Win2008: Boot from mirrored dynamic disk fails!
- by Daniel Marschall
Hello.
I am using Windows Server 2008 R2 Datacenter and I got two 1.5TB S-ATA2 hard disks installed and I want to make a soft raid. (I do know the disadvantages of softraid vs. hardraid)
I have following partitions on Disk 0:
(1) Microsoft Reserved 100 MB (dynamic), created during setup
(2) System Partition 100 GB (dynamic)
(3) Data partition, 1.2TB (dynamic)
I already mirrored these contents to Disk 1. Its contents are:
(1) System partition mirror, 100 GB (dynamic)
(2) Data partition, 1.2 TB mirror (dynamic)
(3) Unusued 100 MB (dynamic) -- is from "MSR" of Disk 0, created during setup.
Since data and system partition are mirrored, I expect that my system works if disk 0 would fail. But it doesn't.
If I force booting on disk 0: Works (I get the 2 bootloader screen)
If I force booting on disk 1 (F8 for BBS), nothing happens. I got a blank black screen with the blinking caret.
I already made disk1/partition1 active with diskpart, but it still does not boot from this drive. Please help.
Both partitions are in "MBR" partition style. They look equal, except the missing "MSR" partition at the partition beginning (which seems to be not relevant to booting).
