On my computer, I have Windows 8.1, Linux Mint, and recently Arch Linux, installed in a partition scheme like so
/dev/sda1 SYSTEM (Win 8 bootloader, BCD, etc.)
/dev/sda2 Windows 8.1
/dev/sda3 Extended
/dev/sda6 /home
/dev/sda8 Linux Mint
/dev/sda9 Arch Linux
/dev/sda10 /boot (Grub 2)
When I installed Linux Mint, I installed GRUB2 to a /boot partition. I then installed Arch, and overwrote the information in /boot with grub-mkconfig.
It’s now impossible to boot into Mint. I can boot Windows fine, but when I select Mint in the GRUB2 menu, it loads Arch instead. There’s things I would like to use Mint for, but I am unable to now. This is on a BIOS install.
How can I get back into Linux Mint?
