FreeBSD 4.7 + WinXP + GRUB problem

2002-12-16 Thread Aron Silverton
I attempted to set up a notebook with a single drive to dual-boot and 
now I am having a problem booting into XP.  Here's the story:

I split a notebook's hard drive in half (10GB each half) and installed 
XP (NTFS) on the first parition.  I installed FreeBSD 4.7-Release on the 
second half.  I was originally unable to boot FreeBSD, but this was 
because I did not select a boot manager during the install phase.  I 
went back into /stand/sysintall and installed the FreeBSD boot loader. 
Upon a reboot, I was presented with the

F1 ??
F2 FreeBSD

menu and was able to boot either OS without any problems.  Yeah.  I 
thought that it would be fun to try GRUB, so I did the following:

1.  Built the GRUB port
2.  Made the directory /boot/grub and moved the stage1, stage2, and 
*stage1_5 files there from /usr/local/share/grub/i386-freebsd
3.  I created a menu.lst file under /boot/grub with the following in it:
(only relevant sections shown)

title FreeBSD
	root (hd0,1,a)
	kernel /boot/loader
title WinXP
	root (hd0,0)
	makeactive
	chainloader +1

4.  I created a GRUB boot floppy per the instructions in the manual, 
rebooted, and performed the following steps:

grub find /boot/grub/stage1
 (hd0,1,a)
grub root (hd0,1,a)
 Filesystem type is ffs, partition type 0xa5
grub setup (hd0,0)
 Checking if /boot/grub/stage1 exists... yes
 Checking if /boot/grub/stage2 exists... yes
 Checking if /boot/grub/ffs_stage1_5 exists... yes
 Running embed /boot/grub/ffs_stage1_5 (hd0,0)... failed (this is not 
fatal)
 Running embed /boot/grub/ffs_stage1_5 (hd0,1,a)... failed (this is 
not fatal)
 Running install /boot/grub/stage1 (hd0,0) /boot/grub/stage2 p 
/boot/grub/menu.lst ... Succeeded
 Done.
grub reboot

I wasn't sure what to think of the warnings, so I proceeded.  After the 
reboot, I got the same F1, F2 menu that I started with.

5.  I used my XP CD to repair the MBR thinking that it was the problem. 
 I ran fixmbr and rebooted.

Upon the reboot, I got the GRUB menu.  Selecting the FreeBSD option 
worked fine, but selecting WinXP returned me to the menu.  I was able to 
see a very quick error message saying, Filesystem type unknown, 
partition type 0x7 before the menu was redrawn.

6.  I rebooted using the GRUB boot floppy, and repeated step 4.  This 
time, I substituted setup(hd0) for (hd0,0).  Does that make a difference?

I got the same behavior as before - FreeBSD boots, XP does not.  I tried 
writing a new MBR once again, issuing commands from the GRUB prompt, 
changing root to rootnoverify in the WinXP commands.  No good.

Any suggestions as to where I went wrong and how I can get my WinXP 
install back or is it too late for me?  If it is too late, should I be 
able to reinstall XP on the first partition and maintain my FreeBSD 
install on the second?

Thanks,

Aron

Change that to rootnoverify and see if it helps

hd0 is usually what is used.

Shouldn't be too late.

I have a page on Grub that might or might not be of use, as it's dated,
