GRUB rebooting after loading stage1.5?

Bug Description

After a fresh install of Hoary, Windows seems to keep screwing with grub. If I
just boot into Linux, everything is fine, but after booting into Windows, my
next boor goes into an infinite reboot loop. After POST, the screen says "GRUB
loading stage1.5." and then the machine reboots. This is temporarily fixable
using grub from a Knoppix cd to redo the mbr, but booting into Windows again
fubars things. Didn't have this problem previously running
hoary-upgraded-from-Warty on this same machine. It only appeared after a clean
install of Hoary Final.

I'm not the only one having this problem: see

If it is fixed by reinstalling GRUB in the MBR, and booting into Windows breaks
it, then this would seem to imply that booting Windows is modifying the MBR.
This shouldn't happen, but if it is, that seems like a Windows problem, rather
than a GRUB problem.

Are you able to boot into Ubuntu several times in a row without trouble?

Indeed I am. I don't get the reboot loop until I boot into Windows. I reported
it as a bug because I never had the problem until installing Hoary Final and
nothing changed about my Windows partition. Installed Hoary on the same
partitions that had Warty-to-Hoary on them (just let the installer format the
partitions).

This might be a bit of a heavy-handed test, but if you install Warty on the
partition again, does it fix the problem?

Nope. Still getting the reboot problem. Worked fine with Warty before though.
 Not sure what changed. :-/

If you are not using Novell stuff in your Windows, then this bug report is not a duplicate of bug 26058 (see [ http://savannah.gnu.org/bugs/?func=detailitem&item_id=15048#comment5 ]).

Jess Little, could you, please, confirm that you are using Novell ZenWorks (or something similar) in your Windows partition? Otherwise, this bug report should be reopened.

My setup has changed since then, but at the I was using ZenWorks on that machine. This bug can stay closed.
