Installing Windows in GPT Partition Style

Question

Recently, I received three laptops from my family members for installing Windows.

In one laptop, Windows 10 is installed with one volume i.e. C: and with data (like files, images, video, etc). And C: is GPT partition style.

In second laptop, there is one volume i.e. C: with data (like files, images, video, etc). C: is GPT partition style. And the error message on screen is “Operating System not found”. And

In third laptop, there are three volumes (C:, D: and E:) with GPT partition style. Data (like files, images, video, etc) are in both volumes (D: and E:). And the error message on screen is “Operating System not found”.

I have to install Windows 7 in all three laptops without losing data.

I have two bootable USB sticks created by Rufus. One is with MBR Partition scheme for BIOS or UEFI. And another is GPT partition scheme for UEFI. I am not able install Windows with any sticks.

I have gone through some web links but not useful.

Irrespective of manufacturer and modal number, how to install Windows in all three laptops?

Answer 1

There's no way to directly downgrade from Windows 10 (assuming even computer 2 and computer 3 are) to Windows 7.

Backup your data the old way, then make sure laptops are in EFI mode (because without hacks you need that to boot from GPT) and format disk before installation.
