What is UEFI boot mode?

UEFI is essentially a tiny operating system that runs on top of the PC’s firmware, and it can do a lot more than a BIOS.

Does MBR erase data?

MBR, Master Boot Record, is the first sector of any disk or diskette. It stores information on how the logical partitions, containing file systems, are organized on that storage medium.
