On the other hand, since UEFI uses the GUID Partition Tables (GPT) instead of the Master Boot Record (MBR), it could easily read devices that are larger than 2.1TB in size. Moreover, it also has a faster booting time and is much more secure than its counterpart. So owing to all these reasons, it makes complete sense as to why users are looking to convert the Legacy BIOS to UEFI/MBR to GPT in Windows 11. If you are also in the same boat, then this guide shall help you out. Follow along.
