And don't forget to edit your fstab. This is mandatory!
This command helps to identify your device names:
ls -l /dev/disk/by-id/
This commands shows the UUID:
ls -l /dev/disk/by-uuid/

Ok booted SalixLive CD and mounted root of installed system:

Code: Select all

su
mkdir /mnt/myroot
mount /dev/sda3 /mnt/myroot
cd /mnt/myroot
nano fstab

But I can't edit the file due to lack of permissions. Any suggestions.

Edit:
Ignore that just rebooted, tried again and now able to edit fstab. Not sure what I did wrong the first time around.

Despite doing a new GUI install which wrote uuid to lilo.conf and editing fstab to use uuids , system still will not boot.

Can anyone see what I have done wrong?

What does "will not boot" mean?

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,3)

You need to pass root=/dev/disk/by-uuid/... or root=UUID=... (not sure whether the UUID= one works) to the kernel. Also make sure you built and load an initrd with udev (-u) included. Important!!! Don't use the lilo root= option. Put root=/dev/disk/by-uuid/... into an append or addappend list!!!

Sorry, but that seems to my knowledge about lilosetup impossible. You would have to generate an initrd (with udev), modify the fstab and change the lilo.conf to load that initrd. If you specify the root, boot lilo options with UUIDs it's only used at install time. Lilo resolves it to major/minor, I guess, which is effectively /dev/sdXY. But it definitely looses the uuids for boot-time that way. If you were correctly specifying the uuids so they're used at boot-time, any system without an initrd (with udev) would be broken.

I used grub; installed it and used the terminal to run it. I have multiple operating systems on my PC and tonight installed Salix OS. Grub showed my other operating systems on each partition where as prior to running grub I could only see Salix and Vista. All of the partitions with each operating system showed up with grub; but not with the default boot loader.

I installed grub2 and sg2conf to get my other partitions installed with the new grub boot loader..
