Windows Cannot be Installed – MBR to GPT Conversion

The problem occurred during the installation of Windows 7 operating system.

With this problem, I want to delete the existing partition of my hard disk. Then I wanna create a new partition,  but when I began installing the Windows operating system the message. The following error message displayed:

“Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks”.

This  error  means, the existing partition or layout of the storage device  is not compatible for the installation of  Windows 7 Operating system.

To fix the problem, I  have to convert the disk layout to GPT format.

Difference between MBR and GPT

MBR disks have single partition table to keep track all the blocks in the partition.  If the table becomes corrupt/damage, the entire disk must be recovered from backup.

While Windows GPT-based disks have multiple, redundant partition tables so that if one is detected as being corrupt, it can self-heal itself from a redundant copy of the table.
