BIOS: Hard disk not detected!

[Myhealzor]

hey,

I put my first pc together with all new parts except my dvd drive and hard drive. Now after I read:
''Adapter 1 Disks Information: AHCI Mode
No hard disk is detected!''
it fails to boot, I get like a 1 sec blue screen

But when I go to BIOS -> Advanced Mode -> SATA configuration I see
SATA3G_4 detecting my dvd drive
5: ST31000333AS (1000,2 GB) this is my 1 tera Seagate HD

So its like detecting it and not detecting it?
Worth noting is I also tried an old 180 and 60G SATA3 HD and all 3 of these HDs are off PCs that died; virusses, hardware failure
Maybe all of these HDs have just bitten the dust?

What exact motherboard do you have?
