This computer's hardware may not support booting to this disk

Feb 10, 2019
My friend got a server mobo in his PC.
He got only 1 SSD plugged in. (120GB)
When he tries to install windows 10 he get this error: "Windows cannot be installed to this disk. This computer’s hardware may not support booting to this disk. Ensure that the disk’s controller is enabled in the computer’s BIOS menu."
In the "Where do you want to install Windows?" part, he got 3 primary disks.

In DISKPART it seems like 3 SSD not one.

Sorry for my bad english.
Get your friend to find that mobo' documentation, and examine BIOS / RAID settings. Ask him also to run again these tests without any SSD attached. 120GB SSD should appear as 111GB storage, and these "three" drives total to very round figure of 100GB.
