I want to convert GPT to MBR, here's the reason why:
Recently, I had Windows 8.1, I was thinking to download the .ISO file from Official Microsoft website and reinstall Windows 8.1, and I did. I booted the USB and saw that my laptop (Lenovo B590) was ignoring it, it was just booting to Windows.
I just realized that my disk was GPT, not MBR, and that's the problem. Ubuntu was installed fine, but Windows didn't. I formatted my C:/ drive, just to check if anything works. Nothing did. When I formatted my C:/ drive, I had no OS. And I always got the "Your PC needs to be repaired" notification when I turned my PC on. So I just installed Ubuntu so I can fix the problem.
Please give me detailed answers, I want to convert my GPT disk to MBR.
Back to the story, I realized that I can't install any Windows.
Please, I really need answers about the following:
- Can I install Windows 8.1 on GPT, if yes then how?
- If the above question's answer is "no", then how can I convert my GPT disk to MBR, in able to install Windows?
Update: My boot order is correct. I booted the USB with Rufus, my USB is 32GB.
gdisk
in Linux, Aomei, Easus or Partition Wizard. See Converting between GPT and MBR without losing data. But this isn't the solution to your question which is an XY problem
