Package: grub-pc
Version: 1.98+20100804-14
Severity: important


I installed a fresh server in SATA environment using mdadm. All went smooth even rebooting from one or the other disk after installation.
I used a net install SQUEEZE CD from around 08/2010.

After having removed the linux-image-2.6.32-5-trunk-amd64 image from installation, I again tried my RAID setup and from here I'm unable to boot from HDD who whas sda during installation. Worth, when booting GRUB I see the welcome message, than quickly appears some errors and the server is going to reboot, no GRUB Cli even in rescue mode :-(! Pressing SHIFT key during GRUB start gives only a blanck screen, nothing usable.

With a camera I could get an image from the procedure and saw:

GRUB loading.
Welcome to GRUB!

error: no such device 83fe9f48-467b-43bc-bffa-0c0f09be70a5
error: no such disk
error: no suitable mode found

and server is rebooting

the above UUID device is the / partition wich is /dev/md2. Separate is /boot being /dev/md0 partition.

Booting from other HDD or from entire RAID area is working well.

Now I enabled in /etc/default/grub
[...]
GRUB_TERMINAL=console

ran update-grub and try again my RAID area: booting from each HDD is effective!

I checked my raid area with boot_info_script055.sh script, everything is fine (output is filename RESULTS.txt below).
