Question Bios Legacy to UEFI

[gillbill]

Good day,
I'm trying to meet the requirements for upgrading to windows 11 and found I need to enable safe boot. This has led me down a rabbit hole of finding what needs to change in order to make that happen. My bios is still legacy and it needs to be UEFI. I can do so using MBR2GPT, only thing is it can only have a max of 3 partitions at a time (I've gathered a limitation of it's current format). I've found the recovery package is in the last partition (4) using 'reagentc /info' . So I think partition 1 could be the best option to remove. Is there a way to transfer the 'active' to the (C: ) drive, then maybe I can delete the first partition? Is this worth pursuing?
Thank you!

If the drive is currently using MBR, you will need to convert to GPT to disable CSM/Enable UEFI, which that tool is good for. However, are you sure the disk is currently using MBR? That would generally limit you to 3 partitions, so I doubt that is whats being used currently.

You should never have to delete partitions to convert to GPT as it can support far far more partitions than MBR
