Windows 10 can't see SSD - ProDesk 600 G1 SFF

[JP-1983]

I have a HP ProDesk 600 G1 SFF PC with a completely failed hard disk, I have a couple spare SSDs so thought it would be a good idea to use one of these instead of the old mechanical drives. I have tried both an OCZ Agility 3 64GB and a Corsair Force LS 120GB drives, both are recognised by the BIOS and both test ok.

When I try to install Windows 10 it won't display either SSD as an option to install the OS on, but installing to an old Hitachi brick worked just fine.

BIOS seems to be set right - there really aren't that many options to change, and I have updated the BIOS to the latest version with no change. Also now that the OS is installed on the Hitachi drive - under Windows Disk Management the SSD shows up with a warning symbol and the word Foreign. Any ideas - have I got two SSDs which are incompatible or am I missing something else?

Finally got to the bottom of this in case anyone runs into a similar issue, turns out it was nothing to do with the PC.

The two SSDs I had were previously a spanned volume in another system, I had assumed the Windows 10 installation would detect them as useable disks and I'd be able to delete existing partitions and start again as usual.

Connecting the disks to another running system they would show up as dynamic foreign disks under Windows Disk Management, right clicking and importing the disk, then deleting the existing partition was all that was needed for Windows to then see the disk during install. Doh!
