I'm not 100% sure but it seems Mint may be the only one using UUID.
Daryna does not use it in menu.lst but in fstab.
So if it happens again edit fstab (from some working Linux) and exchange UUID for dev
First you have something like
UUID=8cb04e6f-dee9-4de6-980e-d648eba537af /media/sda2 ext3 defaults 0 2
/dev/sda2 /media/sda2 ext3 defaults 0 2
I prefer to keep the UUID for reference
I did not read the topic again before answering (just your last post) as I'm pretty sure this is it...
