HDD not booting Windows 10

[bahenriques]

Hello,

I'm having a problem with my computer after disassembling for house move.

I have a:
asrock 970 extreme3
AMD FX-6350
Strix GTX 980Ti
HyperX 16Gb Ram
Corsair 650 Power supply

The problem I'm having is that after reassembling the computer it's not booting Windows 10. The hdd where I had Windows 10 installed is recognised by the BIOS but Windows itself isn't being recognised. With the recovery disk, it's not even showing the Windows installed hdd as a valid hdd for installing the OS. My Ssd is showing but I can't install Windows 10 on it as it's in Fat32 format and has things I can't lose. Please help!

I've checked in Bios, it's there. Did a CMOS reset just in case, changes USB for Windows install pen, changed sata cable and still not showing. Don't know what else to do.
