hi guyz

i'm still new in your forum and olso new in linux

when FC5 installation complete successfully

the system reboot

in the choice menu when i choose FC5

while loading

then stop and restart

what can i do

When the choice menu is displayed, go to the FC5 line and press the "e" key to enter the GRUB edit mode.

Go to the line that that starts with kernel, and press the "e" again to edit that line. Use the "End" key to move to the end of the line, and the "Backspace" key to delete the "rhgb quiet" at the end of the line, and then the "Return" key to enter the changes.

This will tell the bootup kernel to display its error messages, and to not use the "Red Hat Graphical Boot" system.

Then press the "b" key to boot from the modified boot instructions. (By the way, the modification is only temporary -- It is not saved to the boot file.)

Watch the screen closely for any error messages before the "reboot" happens, an tell us what message is displayed.

Once we know why the reboot is happening, then we might be able to help you.

I have a similar problem. I have two hard disks, each with core5 on them, and I want one to be the backup of the other. On the one, I boot, and get the grub prompt, but nothing else.
How do I restore only grub on this second hard disk?

How did you install FC5 on the two disks? Specifically, did you create and label your own partitions, or just do two "installs."

Your problem might be that you created a logical volume on on each of the drives with the same name, and LVM will only "see" the first volume. You can check this by logging in to the FC5 that works, and running a pvscan to list all the logical volumes on all physical volumes. If this is your problem, a simple solution would be to reinstall to the second drive and not use the default Logical Volume setup. A more dificult solution would be to rename the second logical volume, but then you'd need to create a new initrd file to boot to the second volume. (See my thread http://www.linuxquestions.org/questi...d.php?t=419510 for details.)

Caution: Back up your /boot directory first, since the second install will, most likely, replace the kernel and initrd files there with ones targeted to the newer installation. You'll need to rename the files used there, and then copy the older files back to get both to work. (And, of course, change /boot/grub/grub.conf to refer to the renamed files as well as the older, working, files.)

Suggestion: Create a GRUB boot floppy from your working system before proceeding, so you can boot if something goes wrong. If there's enough room, put the vmlinuz-2.6.15-1.2054_FC5smp and initrd-2.6.15-1.2054_FC5smp.img on the floppy, or point the floppy's grub.conf to the backup version of the files you created if you followed my suggestions, above.

Note: The /boot backup can be on the /boot drive, if it's large enough.

thnx guy man

it gives me 3 errors

1- cannot open root device "vol group 00 /log vol 00" or unknown-block (0,0)

2- please append a correct "root="boot option

3- kernel panic-not syncing:VFS:unable to mount root fs on unknown block (0,0)

plz help guyz

What exactly is the setup of your hard drives?
I would guess that you need to alter your "root=" boot option but i couldnt say how without further detail.

sorry man i still new in linux

if u mean wht is the format of hard drive

i make a partion EXT2 and 1 GB swap partion

did u mean that

No i meant how many hard drives do you have?
Which IDE channels are they attached to?
Where did you make the partitions? (there should be two primary partitions, the /boot one and the LVM PV)
Do you have any other operating systems?

ok man

i hav only 1

the first

i was running on windows xp i format one partion 20 GB as (EXT2) to be for linux and 1 GB swap partion
but this partion is not primary

yeah i hav windows xp

thnx 4 ur help
plz still helping me

hey guyz plz help

Perhaps this is just a transcription issue, but the volume should be:

VolGroup00/LogVol00

from memory - assuming FC5 installs are the same accross the board, and not:

vol group 00 /log vol 00

To the dual disk FC5 installation:

to install grub on the second drive, use grub-install sd1 or hd1 (but check the drive designation). Note grub uses different designations from what you will see in /dev
I'd also check /etc/grub.conf

hi guyz
i reinstalled fedora again
