CentOS - Dec 2005 - FIXED Re: Re: MD Raid 1 software device not booting not even reaching grub

doing that grub-install /dev/sda will give me the "corresponding BIOS
device" error.

But now I fixed it by doing a manual grub install.

first boot with cd1 and type linux rescue at the prompt
when you're at the linux prompt after detecting and mounting the
partitions, do a "chroot /mnt/sysimage"
then
# grub --batch
#grub> root (hd0,0)
 Filesystem type is ext2fs, partition type 0xfd

grub> 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
 Running "install /boot/grub/stage1 (hd0) (hd0)1+16 p
(hd0,0)/boot/grub/stage2 /boot/grub/grub.conf"... succeeded
Done.

#grub> root (hd1,0)
 Filesystem type is ext2fs, partition type 0xfd

#grub> setup (hd1)
 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 (hd1)"...  16 sectors are
embedded.
succeeded
 Running "install /boot/grub/stage1 (hd1) (hd1)1+16 p
(hd1,0)/boot/grub/stage2 /boot/grub/grub.conf"... succeeded
Done.

#grub> quit

Reboot, you're done.

Question: A simple power outage will kill grub's mbr or am i just plain
unlucky?

You are unlucky.  The disk head can scribble something somewhere
accidently as it crashes.  That must have been the 'somewhere'.
