Delete EFI system partition in Windows7

EFI stands for Extensible Firmware Interface. It is the upgradation of the old BIOS firmware. EFI support MBR and the modern GPT disk partitioning scheme. MS windows 64bit versions support EFI and GPT. If you happen to have a EFI or GPT partition scheme on your Hard Drive you might have problem using it in older version on windows (xp,win7 32bit).
Following are the step to delete the EFI or GPT partitioning from you Hard Drive in Win7.

1. Type cmd in StartMenu search box and press Enter, This will open the command prompt.

2. In the Command Prompt type Diskpart. wait for it to open in new command window.

3. You will now see a Command Prompt like window of Diskpart utility as shown below.

4. Inside the Diskpart command window type list disk. This will list out the disk connected to the system

5. Type select disk X, where X can be any number disk listed you want to focus on. I did select disk 0.

6. Type list part. This will list out the partitions on the disk.

7. Type select partition X to select the partition from the list of partitions.

8. To delete the partition type delete partition override

9. Type exit to quit DiskPart Utility.

EFI and GPT has a great advantage over the old MBR. It can support disk of sizes upto 9.4ZB way greater than MBR. GPT is surely gonna leave MBR far behind in coming time.
