Re: [LINUX_Newbies] UUID problem

Ubuntu's Fstab lists only the partitions on which it is installed sda3 and
sda4. None of the distributions that grub works for are listed either. I
could understand if none worked, but don't get why some and not others on
the same drive. I tried plugging the drive into another computer and got no
farther.

I am not sure that I understand the idea behing UUIDs. If I wipe the drive
and start from scratch wiping all partitions will this re-occur?
