I had this same problem with my HP Pavilion g6 when trying to dual boot Ubuntu 12.04.3 LTS and Windows 8. That is, even after "successfully" running Boot-Repair, I still had the notebook booting directly into Windows 8. If I pressed F9 before the HP symbol showed up, I was able to get into a Boot Menu (HP's menu? I don't know...) and from there, to select the "Ubuntu" entry, which in turn took me to GRUB 2 and finally to my Ubuntu installation.

Still, I wanted to be able to have the computer boot directly to Linux, without the need for any user intervention.

In the end, Rod Smith's answer above, combined with the information that I found in another forum, did the trick for me. I have Secure Boot disabled and Legacy Boot also disabled.

This is what I did:

• I booted into my Ubuntu installation using the trick of the F9 key in the start up to be able to choose the boot loader.


• Once in Ubuntu, I opened a terminal.


• 
  

  Using the command below, I checked where Windows boot loader was located:

  
  
  

  $ sudo efibootmgr -v
  
  

  
  



• In my case, the original boot loader was in here: /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi . Please note that in your computer it might be in a different place. If so, you will need to adjust the commands below.



• 
  

  As per Rod's recommendation in his answer (the one about how to repair the boot loader manually), I made a backup of that file by moving it one level up:

  
  
  

  $ sudo cp /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi /boot/efi/EFI/Microsoft/bootmgfw.efi
  
  

  
  


• 
  

  Finally, I copied GRUB2's boot loader in that place, "tricking" the system into loading the boot loader I wanted instead of Windows' original boot loader.

  
  
  

  $ sudo cp /boot/efi/EFI/ubuntu/grubx64.efi /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi
  
  

  
  

So finally I had my dual boot working with GRUB2. In case Windows overwrites the boot loader again after an update (as it did with me), I already know the steps to get grub back to its place.

Hope this helps someone. Please let me know if there are any issues with my solution.

I faced the same problem on HP ProBook 4340s with original Windows 8 already overwritten by new Kubuntu 15.04 (I prefer no dual boot). Among other tries, I also tried Boot-Repair (both from HD after its installation and via boot-repair-disk), but that exercise was most probably unnecessary.

What made the trick was the following changes in the BIOS Setup (after computer start push F10 - go to System Configuration - open Boot Options):

1. Check Customized Boot




2. Check off SecureBoot




3. Boot Mode: choose UEFI Hybrid or UEFI Native (I chose UEFI Native)




4. UEFI Boot Order: put Customized Boot to the top




5. Define Customized Boot Option: choose Add + put the setting: EFIubuntugrubx64.efi

We found the correct path string when opening the GRUB via the Boot from EFI File option in the Fast Boot Options (F9). In the beginning, the options list contained:

• OS boot Manager


• Boot from EFI File

After adding the Customized Boot option, it was added to the list:

• Customized Boot


• OS boot Manager


• Boot from EFI File

Ordinarily, running Boot Repair backs up Microsoft's original boot loader file (bootmgfw.efi) as bootmgfw.efi.bkp and replaces the original bootmgfw.efi file with a copy of GRUB (or shim), and the Boot Repair output you posted would show this; however, I don't see such a backup file. Thus, I recommend you do one of three things:

• Run Boot Repair again, but look for options related to backing up and replacing the Microsoft boot loader. Activate those options to continue the process. GRUB might or might not be able to launch Windows; that seems hit or miss -- and more "miss" if you leave Secure Boot active.


• Do the job manually: From Linux, back up /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi (I recommend moving it down one level, to /boot/efi/EFI/Microsoft/bootmgfw.efi, rather than renaming it to bootmgfw.efi.bkp, since the latter is non-standard and makes tools other than Boot Repair and Ubuntu's GRUB unable to locate it). Copy /boot/efi/EFI/ubuntu/grubx64.efi in its place; or if you plan to keep Secure Boot working, copy /boot/efi/EFI/ubuntu/shimx64.efi in its place and copy grubx64.efi to /boot/efi/EFI/Microsoft/Boot using its original name. You'll then need to modify your GRUB configuration to enable it to launch the Windows boot loader in its new location or under its new name. (I've heard that GRUB can't yet launch the Windows boot loader in Secure Boot mode, though, so if you want to launch Windows from GRUB, you may need to disable Secure Boot. OTOH, I've never tried this myself, so I could be mistaken about GRUB's capabilities in this respect.)


• Disable Secure Boot, then boot to Linux and install my rEFInd boot manager by using the Debian package. Once that's done, type sudo mvrefind.sh /boot/efi/EFI/refind /boot/efi/EFI/Microsoft/Boot. The latter command moves and renames files in a way that's analogous to the manual procedure I just described or to what Boot Repair does, but it sets up rEFInd as the default boot loader rather than GRUB. If you want to use Secure Boot, you'll be able to do so by juggling files and installing a new version of shim (Ubuntu's shim is early enough that it won't work properly with rEFInd). Installing rEFInd in this way enables you to boot without using GRUB, and the combination of the install script (executed by the package system when you install the Debian package) and the mvrefind.sh script work around the problems you're having.

For the record, the problems you're having are related to known bugs in HP's EFI implementation. Basically, the firmware is hard-coded to boot from Microsoft's boot loader and to make it difficult or impossible to boot from anything else. I strongly recommend you complain to HP about this; they won't fix such problems unless people complain.

Of the three solutions, using Boot Repair is likely to be the easiest to get working; but as I noted, the non-standard naming that Boot Repair uses can end up causing problems for other utilities in the future. The manual adjustments will require more effort to get working, but will be cleaner in the long run. Some people have reported problems getting GRUB to chainload the Windows boot loader, so either option could give you headaches on that score. rEFInd is much more likely to boot either Linux or Windows without problems, but as you can tell from the procedure, getting it working is likely to require a bit more effort than running Boot Repair again, although probably less than doing manual file-juggling. Using rEFInd in conjunction with Secure Boot requires more hoop-jumping at the moment. (See rEFInd's documentation for details.) rEFInd also presents a prettier user interface than GRUB, which might or might not be important to you.

There's risk involved in all three solutions; EFI implementations vary far too much amongst themselves, which means that either an automated or a manual procedure that works well on one computer can fail miserably on another. To protect yourself, I recommend backing up your ESP (normally /boot/efi under Linux); just pack the files up in a tarball or copy them to a backup directory. If something goes badly wrong, you can boot up with an emergency disc and restore the files. That will probably get the computer booting again.

Hewlett-Packard's UEFI has been giving me heartache for a while. Your fix helped me to restart my HP laptop in GRUB again - without pressing F9 first.

I had one problem: after your fix, I could select Windows 8 in GRUB, but Windows 8 then refused to start and I was shown the GRUB menu again.

My fix:

1. Copying the original Microsoft efi-file to /boot/efi/EFI/Microsoft/Boot/bootmgf2.efi
   


2. Editing /boot/grub/grub.cfg to recognise the renamed Microsoft efi-file

Laptop now boots to GRUB, Ubuntu and Windows 8 now start OK from GRUB.

I spent a day for the same problem and I finally solved it. The following is the exact solution. The full article for solving the problem is here Which is written by Rod Smith.

Useful information

In order to boot into GPT partition table with efi boot loaders. efi files are created by operating systems in the time of installation which must be provided to computer's UEFI bios in order to give it the ability to boot into their coresponding operating systems.

For holding the efi files we need to have one EFI partition. This is usually a partition less than 200MB with fat32 format with the label of EFI system. It includes .efi files and their dependencies (In the shape of .dll or .efi) needed for booting into any of the bootable partitions (usually operating systems). In my computer this partition has structure shown by the following schema:

EFI

   |_Boot

     |_fw

   |_Microsoft

     |_Boot

     |_Recovery

   |_Ubuntu

     |_fw

Normally .efi files can have any name but it seems that some computers are looking for specific names. So I mention the standard names too.

1. Boot Folder: Is is recognized as the default boot option and if NVRAM is erased for a reason. This will be used by default. The efi boot loader's name is "bootx64.efi". When you want to choose a default efi boot loader copy your efi file and all files around it to the boot folder and rename the efi file of your source into "bootx64.efi".




2. Microsoft Folder: It holds windows's efi boot files. There are several efi files but the main one is "efibootmgfw.efi". I am sure that this is used by windows to boot.




3. Ubuntu Folder: It holds Ubuntu or Mint's efi file. There are several .efi files but the main one is grubx64.efi

what to do?

There are already some boot options that are installed in the time of operating system installation. However, they can be gone from bios's boot options for different reasons such as removing and reinstalling an HDD or installing a new operating system or even a new motherboard battery. There are two solutions to recover the boot options.

1. (Not recommended) As it is described in some answers we can replace a working boot option with the one that is not working. But the problem remains the other way.




2. Register the missing efi boot loader file manually.

How to do?

1. Boot from Linux bootable flash (I use Linux Mint's bootable flash). This must be an EFI usb. (GPT usb that can be created by programs like rufus)



2. 
   

   Mount the EFI partition, your distro may do this automatically. Skip this step if /boot is available and shows a structure similar to the one above. Modern Ubuntu's should do this for you.

   
   
   
   
   

   1. Find the address of your EFI partition. This can be done by using parted command or Disks program. It is usually the first or second partition in the bootable disk.(/dev/sda1 or /dev/sda2) This partition is usually between 100MB-200MB with FAT32 and partition type of EFI System.

   
   
   2. 
      

      Mount the EFI partition.
      You can use df command to check if the partition is mounted before.

      
      
      

      df  /boot/efi
      
      

      
      
      

      If the partition is not mounted before(Is not shown in the previous command) Mount the partition by the use of mount command:

      
      
      

      mount  /dev/sda1  /boot/efi
      
      

      
      
   
   
   
   


3. 
   

   Now if you browse /boot/efi you will see the file structure similar to that of mine explained above. Control if there you can find the folder of your lost operating system. In my case computer's bios only was able to see the windows boot option, however I also had linux Mint's Grub boot option.

   
   
   
   
   
   • 
     

     (Not recommended) My windows boot option was working so First for testing purposes I made a backup of Microsoft folder which holds a bunch of files among with the boot efi file of windows. (bootmgfw.efi) Then I renamed the ubuntu folder into Microsoft, next I renamed the grubx64.efi to bootmgfw.efi. After restart, Instead of booting into windows grub menu is loaded, however, this time booting to windows was only possible with grub. And direct boot to windows was not possible.

     
     
     

     sudo cp /boot/efi/EFI/ubuntu/grubx64.efi /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi
     
     

     
     
   
   
   • 
     

     (Recommended way) Just write the address of the efi file that you want its related operating system to be seen in the boot options of bios. In my case Linux Mint was missing from the computer BIOS's boot list. The address of its efi file was /efi/ubuntu/grubx64.efi relative to EFI partition's root. Then I registered it into NVRAM by using efibootmgr command.

     
     
     

     efibootmgr -c -d /dev/sda -p 1 -l \efi\ubuntu\grubx64.efi -L nameForBootOption
     
     

     
     
     

     in p 1 part of the command the 1 defines the partition number of efi partition in the given disk.
     nameForBootOption is a custom name given to the boot option

     
     
   
   
   
   

*Take care to write the correct address. When You mount the partition in linux. It mounts the partition to some folder under the root, that extend the real address into something like /media/mint/CC1F-9708/EFI/ubuntu however we only need to give /EFI/ubuntu part.

*Disks program is wonderful graphical tool that is on linux Mint's bootable flash by default. It can be used to check and find EFI partition and also can be used for mounting the EFI partition without using any mount or parted command. You only need to search for it in menu, Preferences, Disks.

You are affected by this bug: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1091477

Solution:

1. via Gparted, create another EFI partition (FAT32, 200MB, located inside the first 100GB of the disk)


2. move the 'boot' flag on it


3. make Ubuntu use this new ESP (eg via Boot-Repair --> Recommended Repair).

I faced the similar problem after installing Cent-OS 7 over windows 10. here is the below process i followed.

• initial OS was windows 10


• installed cent-os 7 using uefi usb created by rufus

problem : windows 10 was loading and cent OS boot menu was not even getting displayed.

1. How i solved:


2. went to Bios


3. enabled legacy boot ( just an extra step for future precautions)


4. go to Boot options


5. click OS boot manager


6. Move CentOS UEFI above windows : press f10 to save


7. click OD bootmanager again and verify it.


8. press f10 to save and exit

Now your system will boot in centos UEFI

since we enabled legacy boot we can choose esc key to go to bios or other boot options

I found a way to get my HP Pavilion g7-2269wm (UEFI) to boot rEFInd (GRUB may also be possible) without replacing bootmgfw.efi with rEFInd or GRUB

I installed rEFInd and added rEFInd to the boot managers list using sudo efibootmgr -c -d /dev/sda -p 2 -L "rEFInd" -l "EFIrefindshimx64.efi"

Rebooted using F9 to select rEFInd and then selected Ubuntu.

Then renamed bootmgfw.efi to bootmgfwms.efi using

sudo mv /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi /boot/efi/EFI/Microsoft/Boot/bootmgfwms.efi

Then I rebooted and it rebooted into rEFInd without having to use F9.The Windows 10 entry was now missing so I selected Ubuntu.

Then to get back the Windows 10 entry I ran

sudo mv /boot/efi/EFI/Microsoft/Boot/bootmgfwms.efi /boot/EFI/EFI/Microsoft/Boot/bootmgfw.efi

Then I rebooted and rEFInd comes without pressing F9 and Windows 10 appears as a entry.

It's a further answer for mairabc's one for those who, like Vince or I, can't boot into windows. You'll need the fs_uuid:

# grub-probe --target=fs_uuid /boot/efi/EFI/Microsoft/bootmgfw.efi

and the hints_string:

# grub-probe --target=hints_string /boot/efi/EFI/Microsoft/bootmgfw.efi

Then you have to edit the file /etc/grub.d/40_custom like that:

menuentry "Microsoft Windows x86_64 UEFI-GPT" {

    insmod part_gpt

    insmod fat

    insmod search_fs_uuid

    insmod chain

    search --fs-uuid --no-floppy --set=root your_hints_string your_fs_uuid

    chainloader /EFI/Microsoft/bootmgfw.efi

}

Save it and do a

# update-grub

reboot into windows...

After installation of Ubuntu 14.04 64 bit on a notebook HP-15-r248nf with Windows 8 upgraded to 10 installed which happened smoothly besides a problem with a dropping Wifi connection with a Realtek Wifi driver (solved using
echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf
),
the PC still booted under Windows. Ubuntu through grub became only available when using the ESC key during the boot phase. boot-repair did not help, it actually installed quite a number of options in grub, but grub was still not directly accessible.
In fact it was simply required to change the boot order from the default. At the boot step after switching on the PC type Esc, then F10 to enter the BIOS setup. Go to the tab “System configuration”, down to “Boot options”. Press Enter. Disable “Secure boot” Go down to UEFI Boot order. I put using F5/F6 the OS Boot manager on top (probably not required). Select “OS boot manager” with Enter. Using F5/F6 move ubuntu to the top above Windows Boot Manager. Leave the Bios setup with F10 Save/exit and confirm the changes you made. Now you will be directed to grub where you chose the option Ubuntu marked with a star on top which will boot automatically after a short delay.

This is NOT a Windows problem!
The HP firmware is totally buggy as it does not use (or even support properly) the UEFI firmare variable "BootOrder".
I think the only fix to this is to replace the Windows boot loader file (as some already mentioned) with your grub.efi.

My scenario is similar to Michal Žarnay's Aug 19 '15 at 15:20 post: I got some HP Pavillion Slimline 400-314 mini towers, had no need for the pre-installed Windows 8, so immediately repartitioned the HDD and installed Ubuntu 14.04 and Grub2.

Unfortunately, the Pavillion's BIOS menu is extremely limited in boot configuration. It doesn't have most of the fancy choices that most others are describing here. Even attempting to change boot order fails to stick.

The ONLY solution I've gotten to work is to use the "alternative naming" workaround as described in the "Alternative Naming Solutions" section of this blog.

On my HP laptop I did as follows, step by step:

1 - Boot into ubuntu with F9

2 - Check where Windows boot loader is located

sudo efibootmgr -v

In my case /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi

3 - Backup .efi file:

sudo cp /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi /boot/efi/EFI/Microsoft/bootmgfw.efi

4 - Replace original .efi file by the ubuntu one (the trick):

sudo cp /boot/efi/EFI/ubuntu/grubx64.efi /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi

5 - Add windows 10 menuentry on grub. Open /etc/grub.d/40_custom and add this menu entry in the end of file:

menuentry "Windows 10 click here!" {

    search --set=root --file /EFI/Microsoft/bootmgfw.efi

    chainloader /EFI/Microsoft/bootmgfw.efi

}

6 - Save 40_custom and:

sudo update-grub

7 - On bios Disable Secure Boot (I'm not sure if it is needed)

8 - If everything went right, it will boot on ubuntu by default and windows 10 will be another option on grub.

It was easier than I thought.

I confirm that @Vitor Abella's steps solved the dual boot issue for my HP 2000-notebook, except that I will need to do either of the following (as was mentioned by @mairabc):

• enable legacy boot (by default, security boot is disabled)

or

• disable legacy boot, and enable security boot.

If you don't want to move around boot files, you could try changing the boot sequence manually:

Get into ubuntu manually and check the current boot sequence and their ID's using:

sudo efibootmgr -v

then change the boot sequences using -o and the ID's (in boot order left to right):

sudo efibootmgr -o 0000,3000,0001,2001,2002,2003

Example:

1. Show current boot settings

$ sudo efibootmgr -v

2.Change boot order (we want to start ubuntu first, that will show the boot menu at startup):
Note that the first try gave an error because it couldn't find Boot2003 (floppydisk drive?), as you can see it is recreated after reboot though.

$ sudo efibootmgr -o 0000,3000,0001,2001,2002,2003

I've got a 2018 HP laptop, 14 inch with Windows 10 and Ubuntu dual boot. I used to press F9 to choose which OS I wanted and I have done for a few weeks now.

Solution:

• Shutdown and press F10 to go into BIOS




• Navigate to the part of BIOS which lists the boot order




• Press enter on OS boot manager.




• use F5 or F6 to switch Ubuntu with Windows.




• Save and exit.
