MBR-based partition table schemes insert the partitioning information in the master boot record (MBR) (which on a BIOS system is also the container for code that begins the process of booting the system). In a GPT, partition table information is stored in the GPT header, but to maintain compatibility, GPT retains the MBR entry as the first sector on the disk followed by a primary partition table header, the actual beginning of a GPT. Now here comes to the problem to convert this disk to MBR disk, there is a very simple and easy method to convert this disk to MBR disk but you will lose your data and partition from that disk. I assume that you have an empty disk where you have accidently enabled GPT and you need to convert it back to MBR disk.
If you are using Windows XP and you are not able to access or modify GPT protective disk, you can easily convert a GPT disk to MBR Disk by using the clean command under DiskPart Disk Utility, which will remove all data and partition structures from a GPT disk.
1. Go to command prompt (Go to Start Menu, RUN and then enter CMD command)
Enter DiskPart command.
and then type list disk command (this will show all the disk attached to the system)
Use select command to set the focus to the specified partition.
For example I will select the disk 2 “select disk 2″.
Use clean command to remove GPT disk from the current in-focus disk by zeroing sectors.
2. Go back to Disk Management, you can see all disk is “unallocated” now. Right click on disk, choose Initialize Disk.

we are very thankful to you for giving us such a great knowledge.
thanks and regards
Thank you!! This took me from WTF to NTFS in about 4 minutes.
Hi, as long as you are using diskpart anyway, why not complete the job of setting up the disk? (Check you have the correct disk selected with the “list disk” command. Type Help to find out what to do.)
After the clean command finishes:
>CREATE PART PRIMARY
>FORMAT FS=NTFS LABEL=”New Volume” QUICK
You actually only need the first 3 letters of each command.
“cre par pri” is the same as the first command above.
Thanks a lot. The above worked well.
keep it up.
Thank you so much. I’d been struggling with how to stripe my new WD Thunderbolt Duo for a few hours now. This was so simple and it worked. It would have sucked to use the drives individually.
