Answer :
Final answer:
MBR stands for Master Boot Record. It's a boot sector that was traditionally used on BIOS systems, but can cause issues on UEFI systems that usually require a GPT partition table.
Explanation:
MBR stands for Master Boot Record, which is a type of boot sector that was traditionally used in computers with BIOS firmware. When trying to install Windows on a system that uses UEFI firmware, you might encounter an issue - such as the error message you mentioned - if the hard drive you want to use has an MBR partition table. UEFI systems typically require GPT (GUID Partition Table) instead of MBR as they support larger hard drives and more partitions. The Master Boot Record contains the boot loader for the installed operating system and information about the disk's partitions.
