Grub stage2 fails with "Invalid partition table"

Description of problem: Grub Stage 2 fails with the error "Invalid Partition Table" Version-Release number of selected component (if applicable): 97-13 How reproducible: Consistently Steps to Reproduce: 1.Install grub 2.Boot 3. Actual results:Stage 2 failure Expected results:Normal boot Additional info:I have a partition that contains just grub on /dev/hda2. That version of grub chainloads either /dev/hdb2 or /dev/hdd2 where grub is also installed as part of a complete redhat root partition. hdd2 contains version 4 of enterprise, I just installed version 5 on hdb2. hda2 (and hdd2) have version 95-3.8 of grub. hdb2 has 97-13. When the grub-97-13 on hdb2 executes (after being chainloaded from hda2 grub-95-3.8), stage2 fails as described above. When grub-97-13 was installed on hda2, it failed their as well. When grub-95-3.8 is installed on hdb2, it boots successfully (after being chain loaded from grub-95-3.8 on hda2). Grub-95-3.8 on hdd2 has always booted successfully when chainloaded from hda2 grub-95-3.8. When hdd is removed from the system entirely, the problems with grub-97-13 continue. The boot sector on both hda and hdb have signature aa55 in the last 2-bytes. A listing of the partition tables for hda and hdb is attached.

(In reply to comment #0) For a number of reasons, I reinstalled Enterprise 5. When I did so, the problem with grub-97-13 disappeared. So I would have to re-classify the problem as not repeatable. There was nothing unusual in the initial install. The problem with grub-97-13 occurred the first time the system rebooted after the install (before I even had an opportunity to mess it up). And it occurred after manually re-installing grub-97-13 on hdb2, hdb, and hda2. It disappeared when grub-95 was re-installed on those partitions.
GRUB 0.97 doesn't contain the string "Invalid Partition table" at all. What makes you think that it was GRUB failure at all?
Hi, So, if I get it right, there is no issue after reinstall? So it could be really corrupted filesystem, I expect. Closing as NOTABUG. If I misunderstood you, feel free to reopen. Regards Vaclav
