I have a redhat 5.2 system that will not boot, system halts at the grub prompt.
Been on the phone with redhat all morning and am now running an sosreport for them to look at.
I have even tried to run theinstall media and do an upgrade to get the system to boot, when it attempts to update the boot loader a bug alert pops up and that's it..

Is their anyway to boot the machine from the install CD or rescue media and worry about the getting grub fixed later?
I really need to get this machine back running as well as gte a backup of the system..

Not sure what happened..system downloaded several security updates this morning and while it was installing one a bug error popped up.. Everything was fine until I rebooted, then it would not boot..

The link you gave does not work..http://www.bootdisk.com/linux.htm
Is there no way to boot the system from the rescue / install media and then load the system on the harddrive?
If I recall correctly, suse had an option to load the system on the harddrive from the install media..

Link http://www.bootdisk.com/linux.htm works for me

when system gets to grub>

can you type commands or just freezes?
if you can type try this

root (hd0,0) (assuming that you have linux on first partition first disk)
kernel (hd0,0)/boot/yourkernel
boot

also you can use http://www.knoppix.org/ to boot in and fix /boot/grub/grub.conf which seems to be erroring

The rescue mode is usually the way to go, I've never had problems with it before.
It sounds like a bad update.

Can you post the error messages?

Everyone helped solmewhat..
Finally got it back up and running.
I had to do a clean install and mount my backup drive and copy the backup tar to the filesystem.
Then I had to boot into rescue mode and load the file system which let me access the backup file.
Then I had to un mount /dev/sda1 so the backup would not overwrite the /boot folder.
