I cloned a drive, starting with the MBR:
dd if=/dev/hda of=/dev/hdc bs=446 count=1
However, after installing the cloned drive in the new machine, all I get
is a scrolling GRUB filling the screen. I downloaded an amd64 netboot
CD, mounted / and /boot in /target, and issued
chroot /target
Everything in there works fine -- the applications run. (I'm sitting at
another computer at this point with remote access to the installer). But
what I was counting on working, namely
grub-install /dev/hda
which used to work on i386, maybe a year or two ago, now gives me
"/dev/hda: Not found or not a block device." If I do df, chroot sees
only this:
Filesystem 1K-blocks Used Available Use% Mounted on
sysfs 7740384 3197252 4149944 44% /sys
df: `/dev/pts': No such file or directory
tmpfs 7740384 3197252 4149944 44% /dev
In the installer shell, I get
~ # df
Filesystem 1k-blocks Used Available Use% Mounted on
tmpfs 102400 30248 72152 30% /
/dev/cdroms/cdrom0 86390 86390 0 100% /cdrom
/dev/ide/host0/bus0/target0/lun0/part2 7740384 3197252 4149944 44%
/target
/dev/ide/host0/bus0/target0/lun0/part1 97826 9736 82871 11%
/target/boot
So it's using devfs, which I thought was deprecated? What do I tell
grub-installer?
When I chrooted to /target, it rewrote /etc/fstab (why?), like this:
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/hda2 / ext3 defaults,errors=remount-ro 0 1
/dev/hda1 /boot ext3 defaults 0 2
/dev/hda5 none swap sw 0 0
/dev/hdc /media/cdrom0 iso9660 ro,user,noauto 0 0
In dmesg, I get
NFORCE3-250: 0000:00:08.0 (rev a2) UDMA133 controller
ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:DMA

hdc: HITACHI DVD-ROM GD-7000, ATAPI CD/DVD-ROM drive
Obviously /dev/hda is seen, since the chroot is running on it.
What can I do? All I want is to rewrite the MBR, the installation itself
is fine.
