Booting to MBR (Legacy) : HP Desktop - M01-F0016

[BJernigan]

Trying to move an old hard drive (MBR) onto a M01-F0016.

Going through BIOS settings and cleared secure boot. Tried multiple tutorials but nothing has worked thus far. The computer loads the Windows GDP drive just fine, but can't see the other drive from Bios.

I need the windows installation from the old disk to boot up so everything is working.

Bios Version: AMI F.12

EDIT*

From the BIOS I can see the Drive in RAID mode, but the drive is AHCI mode.

When I switch to AHCI mode, I can no longer see the drive.

Will not boot the drive regardless.

My guess is that no-one responded because you're not going to be able to boot Windows from the old drive.

Your new PC is probably preloaded in UEFI mode, and the old drive was probably installed in BIOS mode -- the two are incompatible.

And, the old drive has the drivers for its old PC, not the new one.  So, even if it did boot, there would be no way to "check everything" that you want to do because too much of the new hardware simply would not work with the wrong drivers.
