Had to convert GPT disk to MBR which I was unable to installed Windows OS on the Disk Partitions available.
Master Boot Record (MBR) disks use the standard BIOS partition table. GUID Partition Table (GPT) disks use Unified Extensible Firmware Interface (UEFI). One advantage of GPT disks is that you can have more than four partitions on each disk. GPT is also required for disks larger than two terabytes (TB).
You can change a disk from MBR to GPT partition style as long as the disk contains no partitions or volumes.
Here are the steps:
– Using the command line
1. Open an elevated command prompt by right-clicking Command Prompt and then choosing Run as Administrator. 2. Type diskpart. If the disk does not contain any partitions or volumes, skip to step 6. 3. At the DISKPART prompt, type list disk. Note the disk number you want to convert. 4. At the DISKPART prompt, type select disk <disknumber>. 5. At the DISKPART prompt, type clean. 6. At the DISKPART prompt, type convert mbr
- Running the clean command will delete all partitions or volumes on the disk.
- Before you convert a disk, backup any data on it and close any programs that are accessing the disk. (But if you are installing an OS from scratch like me, there is no need to perform this).Source
