How to make a GPT partition active?

Hello,

I recently had a problem and I need to make a partition active, but since my hard drive (SSD) is in GPT, diskpart tells me that to make a partition active, it has to be converted to MBR.
The problem is:

1- Since my hard drive is the one where Windows is installed, I can't format it and convert it to MBR (at least not without losing data on the drive with Windows on it, not to my knowledge).

2- When I install Windows by previously formatting and converting my SSD to MBR, it tells me that to install Windows, it is absolutely necessary to have the GPT format.

So I was wondering, is it possible to make a partition active in GPT?

If this is not possible, please consider (I beg you) the problem and try to provide me with a solution.

Thank you in advance, and sorry if there are any spelling mistakes.

Sure, thanks for the quick response. Do you know how to configure the BIOS to install Windows with an MBR disk?

Look at the captures there: https://www.malekal.com/le-bios-uefi/

Look for options like CSM / Legacy Bios:
Launch CSM (On/Off or Enabled/Disabled) < Enabled
UEFI/Legacy Boot (Both/Legacy Only/UEFI Only) < Legacy Only


Afterwards, it's a bit stupid to set it to MBR.
- You can't move the data to another disk.
- Set your disk to GPT (that deletes everything)
- Leave the BIOS options as they are and Install Windows?

I don't understand why you are so adamant about having it in MBR?

Thank you for your response.

I’m really hesitant, but I think I’m going to stick with GPT.

Again, thank you for your promptness and professionalism!
