Ok, I really hope that someone can help me out here. I have a Windows Server 2008 R2 at Hetzner. It is configured in Raid 1, however the server has turned out to have some problems and will now only boot the secondary plesk installation. I had Hetzner test the disks and one of them is failing. However if I use F8 during startup and boot directly on the second disk, i am not able to boot.
I am guessing that disk 1 is failing, however the boot partition is working fine. Disk 2 is working, however something is wrong with the boot partition.
This is sort of the current status of the Raid system:

The issue now is, that i somehow need to make it possible to boot the second disk, in order to replace the first disk.
I really hope, that someone can help me in the right direction, to solve the problem.
