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):
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
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.
