Hi
I'm having some trouble with grub. Briefly, when I installed orginally,
I installed a 32 bit sarge system first and then the amd64 system, which
has been working fine. For the sake of clarity we'll call this
64bit install 'production' I decided to use the 32bit sarge space to do a
fresh amd64 system ('test') and I stupidly let the installer install grub.
Well
apart from having to mount and edit the 'production' fstab, I managed to
get back into my production system.
But I've tried both grub-install and the grub command line interface:
grub root (hd0,7)
grub setup (hd0)
setup (hd0)
Checking if /boot/grub/stage1 exists... yes
Checking if /boot/grub/stage2 exists... yes
Checking if /boot/grub/e2fs_stage1_5 exists... yes
Running embed /boot/grub/e2fs_stage1_5 (hd0)... 16 sectors are embedded.
succeeded
Segmentation fault
When I try to boot, I get:
GRUB 1.5 (I think from memory)
and then nothing ;(
So it would appear that neither method is installing grub on the mbr
Unfortunately, I don't have a floppy on this machine and so I have to
repeat the 'test' install to get grub installed to the master boot
record. So the installer is successfully installing grub on the mbr.
I've tried this a number of times but not making headway but before
filing a bug report, I thought I'd check here first.
This is a known bug of grub, i had it 2 weeks ago. You won't be able
to install it by hand. I think it is a conflict with something in the
kernel as it only hapens with some versions of the kernel. For
example, with an old 2.6.6 grub works fine installing in the mbr,
but not for newer kernels like 2.6.8 or 2.6.10. You can download DFS
live-cd and try to install grub chrooting to you debian 64
installation. I thing DFS can boot with an amd64 ready 2.6.4 o 2.6.6
kernel.
Thanks Aritz
DSL got me a grub boot disk - thanks.
Strangely, amd64 ready 2.6.4 o 2.6.6 kernels booted fine but nothing
appeared when typing 'root' to login. Booting off the first 32 bit
kernel worked fine.
I haven't yet tried to chroot into my production system to fix grub -
another little project, once I get some more time ;)
Regards
Clive
