How to convert MBR to GPT partition while windows installation.

GUID Partition Table (GPT) and Master Boot Record (MBR) are two types of partition used in hard drives, SSD. Let us talk about MBR; it is a traditional partition of hard disks used in old laptops or pc that comes with Legacy boot mode. But, the GPT partition is used in the latest configuration laptops, which comes with SSD and HDD that supports more than 2TB storage. Moreover, the GPT structure supports UEFI BIOS firmware. The GPT structure has more stability and components than the MBR partition for the Windows operating system.

window installation error:
” Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI, windows can only be installed to GPT disks” this error comes if you boot windows bootable pen drive in EFI mode (GPT); but, your hard disk or SSD partition style is MBR. It would be best to convert MBR to a GPT partition table to solve this problem. Secondly, you can solve this problem by disabling the UEFI boot option.
