I have applied the partition table mentioned above. Windows 7 Disk Management
Tool does not allow to create an Extended Partition on the third Primary
partition slot. Thus I used the Ubuntu installer to do it. At first I tried to
install GRUB2 from Ubuntu 10.10 (Lucid), but the error message remains :-( Then
I tried GRUB1 and succeeded, luckily. Probably there is a problem with the
sector offset or the data partition is too large for GRUB1 to skip over. It is
> 1 TB. In the actual scheme, the 1.1 TB data partition comes after the root
partition (where GRUB is installed).
After a kernel update I have to call 'update-grub' manually, but I am happily
doing this, it is only a minor glitch of Ubuntu 9.10.
If there is a new version of GRUB2 which supports dmraid devices, I happily
test it. Maybe it is only a configuration issue, as GRUB2 has become quite
flexible.
Now I know very well how to restore the GRUB bootloader, I have had much
practise.
Of course I will do a backup from my RAID0 system soon.
The system is very fast. No need to wait for boot and shutdown anymore :-)
