How to make grub2 boot another drive MBR?
4
My laptop (DELL Vostro 3350) has two hard drives:
Main one (/dev/sda), is a ssd mounted on SATA-HDD slot with Ubuntu14.04 (grub2 installed to this MBR). Installed on normaly hd bay
Second on (/dev/sdb), stock hd (with recovery partition etc etc) moved to SATA-ODD slot in place of dvd drive with an adapter
I can not figure out how to boot Windows from grub2. In the past I remember that (maybe with grub1) I could point to second disk mbr and then Windows booted normally.
So my config is:
Disk /dev/sda: 128.0 GB, 128035676160 bytes
255 testine, 63 settori/tracce, 15566 cilindri, totale 250069680 settori

Last, but not the least, from my BIOS i cannot change hard drive boot priority, so there's no way to boot /dev/sdb first.

Did you run sudo update-grub? That should automatically add a chainload to the partition with Windows boot files. If not seen then you have Windows issues.

Run sudo blkid and post the output. Maybe your UUID is wrong. I see sdb3 is marked bootable, but your config refers to ...msdos2 (disks start at 0, but not partitions).
