Hi,

I am new at this, please be kind.

I found out the antivirus software I installed on my dual boot desktop on the win xp side has slowed down my desktop by a factor of more than 10. So I uninstalled the software from executable file downloaded from the software company. This fixed my win XP performance but when I booted my desktop on fedora core 2, I got the following error:
//////////////////////////////////////////////
Red Hat nash version 6.0.19 starting
Reading all physical volumes
No volume groups found
Volume group "VolGroup00" not found
Unable to access resume device (/dev/VolGroup))/LogVol01)
mount: could not find filesystem '/dev/root'
Setuproot: moving /dev failed: no such file or directory
Setuproot: error mounting /proc: no such file or directory
Setuproot: error mounting /sys: no such file or directory
//////////////////////////////////////////////

I googled the net for "no volume groups found" and there are suggestion that I should use LVM tool to fix this problem.

I am wondering if someone can help me with this problem. Please do not suggest that I reload fedora software, I can not afford to loose all my research data.

thanks

Did you do what was suggested?? What was the result? Also, it's hard to give you any guidance, because you don't say WHAT this XP software was, what steps you took to remove it, etc. All we can tell at this point is that you did SOMETHING.
If your data is that important, you have backups, right?? Fedora Core 2 is ANCIENT. You need to upgrade, which will not only fix your problem, but also patch a bunch of security holes, upgrade a LOT of software, and generally make things run much better. You wouldn't run Windows 95, would you? Back your data up, and reload.

If you do have to re-install, give yourself three or four partitions:
Windows
Fedora /
Fedora /home
Fedora swap [only needed if you are low on memory, or want to hibernate]
Then you can always re-install Linux and keep /home intact.

You say you don't want to install because you'd loose all your data. Does that mean you don't have it backed-up? If so, back up NOW: you're living on borrowed time!

Yes, thank you very much . I have learn a lesson. I am backing up all my data now.

Somehow my problem was solved after I setting my BIOS back to the original.

I found out that the problem came from an unauthorized staff had modified BIOS setting by over clocking the CPU.
I realized that this is not a wise thing to do.

My problem is solved. thank you very much.
