I have a Hyper-V Core Server 2012 R2 with the following disks:
Disk 0: SSD C:\SSD (mount point to Disk 1)
Disk 1: HDD C:\ (boot drive)
Disk 2: RAID-5 (not mounted)
Disk 3: RAID-0 (not mounted)
I want to clean disk 2 and create a new partition. I did the following:
C:\Users\mark>diskpart
Microsoft DiskPart version 6.3.9600
Copyright (C) 1999-2013 Microsoft Corporation.
On computer: LITHIUM
DISKPART> list disk
Disk ### Status Size Free Dyn Gpt
-------- ------------- ------- ------- --- ---
Disk 0 Online 111 GB 0 B
Disk 1 Online 232 GB 0 B
Disk 2 Online 10 TB 1936 GB
Disk 3 Online 3724 GB 0 B *
DISKPART> sel disk 2
Disk 2 is now the selected disk.
DISKPART> clean
Virtual Disk Service error:
Clean is not allowed on the disk containing the current boot,
system, pagefile, crashdump or hibernation volume.
DISKPART>
I don't understand the error I'm getting. How can I tell for sure which disk I have booted from? Here's disk management if that helps:

You can see in the screenshot that the second partition of Disk 2 is marked 'System', and that's what the error message tells you about.
It seems to me your Windows Boot Manager and the BCD store is on that partition, you need to move it.
