Last time I installed Ubuntu on a machine that had a different primary |
31 |
OS/bootloader I chose for it to be installed on the Ubuntu partition and there |
32 |
was not problem with it. It was GRUB2 |
33 |
|
34 |
Then I chainloaded it from the primary bootloader. |

The OS can do the same, but this means that he can either: |
37 |
|
38 |
a) Install Gentoo's GRUB to the MBR and chainload from Gentoo's grub.conf |
39 |
Mint's /dev/sda8 boot loader (assuming that he has installed the Mint |
40 |
bootloader to /dev/sda8 instead of the MBR); or |
41 |
|
42 |
b) Install Gentoo's GRUB in Gentoo's partition, or some other partition (e.g. |
43 |
a boot partition specific to Gentoo) and chainload this from Mint's GRUB2. |
