[SOLVED] Do I need to convert my Flash Drive to GPT in order to install Windows 11 in UEFI instead of BIOS?

[orinorin]

I intend to install Windows 11 in UEFI mode and my current Windows 10 is installed in BIOS instead of UEFI in an MBR SSD. I will be converting my SSD to GPT. Do I need to convert the Flash Drive which I will be using install windows 11 to GPT? I'm not very knowledgeable in all the BIOS stuff.

flash drive doesnt need gpt for boot, just fat32 with efi loader is enough

For the bootable flash drive, you could use Rufus (it’s a free program), or format the drive in FAT32, then let Microsoft Media Creation Tool create the bootable drive for you.

NOTE:
In case your PC isn’t “see-ing” the flash drive, insert it in a USB 2.0 port.

If your drive is MBR and need to convert to GPT in order to use in UEFI, you dont have to reinstall the entire disk

Checks if your drive is MBR format

Follow the link to convert MBR to GPT, you will need to use /allowFullOS to work.

You can specific the disk number if its not 0. Eg, mbr2gpt /validate /disk:0 /allowFullOS

Once completed, restart and boot immediately into bios page and change boot mode to UEFI and viola.
