My system has 2 disks. (/dev/sda and /dev/sdb)
I am dual-booting Linux Mint 13 and Windows 7.
Windows 7 is on /dev/sda1
Linux Mint's / is on /dev/sda6
Linux Mint's /boot is on /dev/sda5I just installed Linux Mint 17.
During installation, I formatted all the Linux Mint 13 partitions, but assigned the same mount points.
The Windows 7 partition was left intact.
Bootloader was installed on /dev/sda
After installation, when I tried to boot up, I got the error:
error: no such device: XXXXX Entering rescue mode... grub rescue>
I read around and though that perhaps I installed the bootloader on the wrong disk.
So I repeated the whole Linux Mint 17 installation process, but this time, selected /dev/sdb as the bootloader installation device.
Now, when I boot up, it bypasses grub altogether and boots into Linux Mint 17 directly.
How can I get the system to boot into grub?
ADDED: BTW, not sure if this is crucial, but I just found that the Windows 7 (Loader) is on /dev/sdb1. This was created automatically when I installed Windows 7 (previously, I installed Windows 7 followed by Linux Mint 13).
