Hi,
NOt totally sure if this is the right place, but i think the GRUB loader is more to do with Linux than anything else in this post!
I have just completely reinstalled my laptops after problems with dual booting before (using Norton Partition Magic). I reinstalled XP - after creating 4 partitions on my 40GB laptops drive:
7GB NTFS Windows
5GB EXT2 Linux
500MB SWAP
25GB FAT32 - shared data storage for both OS's
I installed XP, all fine, then installed SuSe 10.1, also all fine.
Booted to both (via the SuSe loader) (Windows is just another option). Updated both, and had bit of play around...didnt change anything thogugh, only really installed a few apps on the windows install.
So, anyway, now when I start the laptop it just comes up with:
GNU GRUB version 0.97 (636k lowe / 1039174k upper memory)
[Minimal BASH-like line editing is supported. For the forst word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ]
grub>
I have done some more research:
OK, I've looked into this a bit, and it seems there's some bad config in the grub.conf file.
So, I tried to load the kernel:
root (hd0,6)
kernel (hd0,6)/boot/vmlinuz
boot
And it loads the kernel but it fails to mount the root.
The actual error is:
VFS: Cannot open root device "<NULL>" or unknown-block(8,6)
Please appeand a correct "root=" boot option
Kernel panic - not suncing: VFS: Unable to mount root fs on unkonwn-block (8,6)
Now when I try to reinstall GRUB, I get this error:
I keep getting an error when I try to reinstall it! (
Error 21: Selected disk does not exist
grub> install --stage2=/boot/grub/stage2 /boot/grub/stage1 d (hd0,6) /boot/grub/stage2 0x8000 (hd0,6)/boot/grub/menu.lst
Error 12: Invalid Device requested

Here is how the config file looks:

Just so it's written down
here';s the /etc/grub.conf too:
root (hd0,6)
install --stage2=/boot/grub/stage2 /boot/grub/stage1 (hd0,6) /boot/grub/stage2 0x8000 (hd0,6)/boot/grub/menu.lst
install --stage2=/boot/grub/stage2 /boot/grub/stage1 (hd0) /boot/grub/stage2 0x8000 (hd0,6)/boot/grub/menu.lst
quit
And /boot/grub/device.map:
(hd0) /dev/hda
If anyone can tell me how this SHOULD look, or what might be wrong, I'd really appreciate it ;o)
Basically I think I just need to know where to put the boot loader (/dev/hda?) or on the Linux partition? And should I replace MBR with generic code and activate partition?
For SUSE it has Image/Device: /boot/vmlinuz (/dev/hda7, root=/dev/hda7)
Could a Windows update have screwed this up??? I saw that SP2 could mess it up on another forum...I cant see it myself, but gotta ask ;p
It worked, I didnt change anything, I rebooted and then it didnt work!
Thanks in advance for ANY amount of help or support you can give on this...i'd only just reinstalled the whole laptop specifically to dual boot, I've done all the Windows config so would rather not start from scratch! The partitions aren't dmaaged anyway (I dont think) so i just need to sort out this boot problem...! Maybe use LiLo? I just want to get to the bottom of the GRUB problem anyway.
