Dual boot scenarios get tricky, it is vital to assume nothing. You left |
| 54 |
out a lot of info, so I have to make some reasonable assumptions. Reply |
| 55 |
with corrections if we're going to wrong route. |

You can only have one primary bootloader, either grub from Gentoo or |
| 58 |
grub2 from Mint, it cannot be both. But it looks like that's what you |
| 59 |
do have. Seeing as you intend to drop Mint eventually, you must |
| 60 |
uninstall grub2 and all it's files from Mint. |
| 61 |
|
| 62 |
Your supplied grub.conf will only work if you have a boot -> . symlink |
| 63 |
present on /dev/sda1. Gentoo normally does this for you. |
| 64 |
|
| 65 |
For Mint you probably need something like this: |
| 66 |
|
| 67 |
title Mint |
| 68 |
root (hd0,7) |
| 69 |
kernel /vmlinuz-<whatever_mint_uses> root=/dev/sda8 ro quiet splash |
| 70 |
<any_other_mint_params |
| 71 |
initrd /initrd-<whatever_mint_uses> |
| 72 |
|
| 73 |
|
| 74 |
You can pick up the correct kernel and initrd arguments |
| 75 |
from /boot/grub/grub.cfg on /dev/sda8 by looking in the menuentry |
| 76 |
sections. |
