I take it you have read |

This did not work for me either, and it would leave me in the same |
| 4 |
place: the root filesystem would not be uncompressed and pivoted to. |

I can't remember exactly what the change was, but I think I retrieved |
| 7 |
the answer from that thread. Try the entry at |
| 8 |
https://forums.gentoo.org/viewtopic-p-6348023.html#6348023, which is: |
| 9 |
|
| 10 |
menuentry "Gentoo Linux minimal install" { |
| 11 |
loopback loop /boot/iso/install-amd64-minimal-20100408.iso |
| 12 |
linux (loop)/isolinux/gentoo root=/dev/ram0 init=/linuxrc dokeymap |
| 13 |
looptype=squashfs loop=/image.squashfs cdroot initrd=gentoo.igz |
| 14 |
isoboot=/boot/iso/install-amd64-minimal-20100408.iso |
| 15 |
initrd (loop)/isolinux/gentoo.igz |
| 16 |
} |
| 17 |
|
| 18 |
The difference being a change in parameter name. isoloop is now |
| 19 |
isoboot. If that fails look at |
| 20 |
https://forums.gentoo.org/viewtopic-p-7719674.html#7719674, but it |
| 21 |
seems to contain the same changes. |
| 22 |
|
| 23 |
Having read all of that again this does seem like the fix. If that |
| 24 |
*still* doesn't work, recursively grep the unpacked ISO file for |
| 25 |
either isoloop or isoboot to find the location in the script you |
| 26 |
should be looking at. |
| 27 |
|
