Question Installing HDD into Old PC

[Nasho23]

I have installed a HGST 1TB Sata ex Laptop into an ASUS P5 KPL-CM - Set BIOS to BOOT from this Drive on SATA 1 - When it starts BIOS Runs and Posts, but Cursor sits blinking on a Blank Screen - NOT BOOTING - WAS Working correctly in Laptop - It was removed to Clone to a SSD.
Thank You

Laptop disk expect there to be the laptop hardware, it doesn't know how to boot into the new/different hardware, you will have to boot from windows installation media and do a fresh clean install.

The blinking cursor means that it did boot from the disk, it just doesn't know what to do next.

You can not expect to boot windows from a different pc. With different pc be prepared to reinstall windows.
If you try to avoid reinstall you get several issues:

boot mode compatibility - system doesn't boot (you have this now),​

drivers incompatibilities - bsods, crashes, bad performance,​

windows activation issues - can not activate windows.​

If I had to guess - windows on laptop was installed in UEFI mode.
Your ultra old pc (LGA775 G31 chipset) doesn't support UEFI boot.
In this situation you get blinking underscore on screen, when trying to boot UEFI windows in legacy mode.

During my Sleep last night, when I solve most problems, my Grain told me to Convert GPT to MBR. Just have to find software that can do this, without losing System and Data - I have handled Activation Issues previously. Thank You.

without losing System and Data

Does the data from this exist on a second drive of some sort?

If not, prepare for tears.


You're attempting to move a laptop drive into a desktop system, and assuming you can make it boot up with the OS?
Good luck with that.

GPT vs MBR is only one of the many problems doing this.
