"Could not configure Windows to run on this computer's hardware".

I don't know what could be wrong with it. I removed some RAM, removed the network adapter because removing the nonessential components was recommended. The only new device is the HDD itself.

“Windows Setup could not configure Windows on this computer’s hardware” installation error on a Windows 7-based or a Windows Server 2008 R2-based computer

You're apparently trying to do an in-place Upgrade. I gave you the steps in my last post to correctly Clean Install Windows 7 by deleting both partitions and creating new ones or just clicking Next to let installer do it for you.

Reset BIOS to defaults: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS

While in BIOS setup set SATA controller to AHCI to try install, then IDE mode if it fails.

The error normally means the BIOS is configured with RAID.
