Description Didier Arenzana 2002-02-27 05:28:12 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT)

Description of problem:
When I install GRUB on the MBR of my harddisk or on a floppy to dual-boot 
between linux and NT4, if I choose NT at the boot, Nt starts to load, and then 
reboots without any message.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.install grub on /dev/hda or /dev/fd0
2.reboot, choose Windows NT

Actual Results:  Windows NT starts loading, prompts me the usual (normal or VGA 
mode, then which hardware profile I want to load); then goes into the blue 
screen initialisation, prints the usual version information string, does some 
hard disk activity, and then the machine reboots.

Expected Results:  NT should finish loading, and show me the login screen

Additional info:

If I start linux the same way, no problem at all.
If I restore the original MBR on the harddisk (I saved it with dd if=/dev/hda 
of=mbr.sav bs=512 count=1; I restore it with dd if=mbr.sav of=/dev/hda bs=512 
count=1), NT loads without trouble.
I haven't tried LILO yet. The hardware is a compaq notebook Evo N400c.
Windows NT is on hda1, NTFS formated, it's an NT4 SP6.

This does actually work in the general case.  It's possible you're hitting a
strange BIOS interaction, in which case it might be fixed in the newer GRUB
packages at http://people.redhat.com/~katzj/grub/.  If you install the i386
package and then run '/sbin/grub-install /dev/hda` (substitute whereever you
installed grub for /dev/hda) and see if that works, I'd appreciate it.

Otherwise, I'll need to know a bit more information about your hardware as well
as whether it works with LILO or not

I tried with the newer grub package (0.91-1.7x); and now everything works just 
Thank you very much for your help.
