I've been using Ubuntu for bout 3 months now and wanted to try something different so I choose Fedora 7, Still havnt got the hang of rpm based gets a bit confusing going from Deb based but then again i'm a noob so never mind.
Anyway when i installed Ubuntu it deleted the grub booter and now I only have Fedora to choose from. I tried to edit it to add ubuntu and it did but everytime it tries to boot in it crashes on the boot up bar right at the beginning. I was wondering if anyone could help, heres a copy of both the /boot/grub/menu.lst i changed

Fedora:

Ubuntu doesn't use Partition Labels and its crashing only coz of that.
Fedora's grub.conf file should look like this
i deleted UUID from Ubuntu root coz sometimes it creates problems after Partition resize.
dont forget to put # sign before hiddenmenu line.

i tried some stuff with ubuntu and grub aswell, but havent figured out what goes wrong.

i did discover that if you use grub-install to install grub, it repleces (hdo,1) or /dev/hda etc to uuid's

i think that is logical, but i do not understand what a uuid is.. is it something that is being calculated from partition info? is is like a serialnumber written to the partition info?

i do think uuid could be handy if partition order changes , or even diskorder when you plug in usb disks ?

so that is why i would like to know what a uuid is, and when it is "set" and why it would change after partitionresize, is the resize program doing that? and why ?
how is uuid determined?

further i dont think using disklabels would cause problems, it just is when users change them that they could cause problems.

that is why i would say using uuids as a unique discription for a partition would be a very good solution, though the "cryptical" numbers dont realy mean anythng to users or admins.

UUIDs are generated by vol_id. Whenever you change partition structure, UUIDs are also changed. Check manual of vol_id.
