Two Motherboards same error, with 2 different drives, different CPU's.
Both drives boot on an Asrock and a Fujitsu board. Have Reset CMOS and have updated Bios..... anything I might be missing? I don't believe it is software. Because they boot and work perfectly when connected to the other PC's but I need these computers for a client and I cannot reset and lose data, programs. They also have Outlook set-up on it and do not want to lose it because it was difficult to set up with work servers.

When I try to boot on the P8H61/USB3 it says Reboot and Select proper boot device or....etc Even though these drives work in another computer. The drives are under AHCI mode not IDE.
I have tried this with 2 of the same Asus motherboards and 2 different HDDs. I cannot figure out what is causing this
