[SLE] HDA has lost GRUB and boots to grub> prompt
Hello All, I have been a SuSE user since 6.4 and have subscribed off and on to this list. I have a problem that I would like some help with: I recently moved my hardware of my server, running SuSE 9.0 with one mounted hDD, HDA, and a running, but unmounted HDD, HDB, to a new case only. The only thing I did not move was one of 2 SCSI tape drives. Initially, everything ran just fine, but it would not do updates. Then after about 48 hrs, the machine hung and I could not unhang it, except by rebooting, then the hardware hung when bringing up the HDDs. I reset it and all went well until it got to Grub and then it just booted to a grub> and nothing was mounted. It is trying to boot HDB, but there is no grub or boot sector on that drive, What is the best way to recover from this? I can mount the partitions on HDA, but I notice no /boot/grub directory. (/boot is there). Should I run a recover from the install disc or should I boot from the install CD and then run grub-install /dev/hda. Grub was originally put in the MBR of /dev/hda. Thanks and awaiting your help.

means it cannot find the menu.lst file
and nothing was mounted. It is trying to boot HDB,
any idea why?

So you're saying you lost the grub sub-directory from the /boot directory? Highly unusual.
Should I run a recover from the install disc or should I boot from the install CD and then run grub-install /dev/hda. Grub was originally put in the MBR of /dev/hda.
You might try running a 'repair' from the install CD but I really think you have some serious hardware problems somewhere. Power supply inadequate in the new box?? or failing? Have you run memtest just to check on memory? Sounds like your box lost HDA at some point. Are these SATA drives by chance? I just replaced 1 SATA and two SCSI drives yesterday in a box and discovered that 10.1 was seeing the two drives a lot differently than grub was. You might be seeing the same thing. When running the rescue system, grub was saying that (HD2) = SDA and (HD0)=SDB but when the system was booted, they were the other way around (like you would expect) -- Check the headers for your unsubscription address For additional commands send e-mail to suse-linux-e-help@suse.com Also check the archives at http://lists.suse.com Please read the FAQs: suse-linux-e-faq@suse.com
