I Can't Convert My GPT Disk to MBR, Any Suggestion

I have a hard disk with three MBR partitions. The first of them got corrupted somehow, so I launched TestDisk to try and rewrite the partition table. But it ended up writing the partition table as GPT instead of MBR. So when I try to reinstall Windows 8, it sees my three partitions, even letting me delete the corrupted one and create a new partition, but I cannot install it because it is partition-tabled GPT. How can I fix this problem? Any help is greatly appreciated.

Besides, there is another method, which is to use the command prompt. This method also can help you achieve the conversion from GPT to MBR. However, it is a more difficult and inoperable way for computer beginners, and this method needs to delete all partitions on your GPT disk. Therefore, if you do not hope to delete all the data, you need to make a backup of your key data.

There are some steps for you:

Step 1. Open Command Prompt running as an administrator and type diskpart.

Step 2. Type list disk and then press Enter. Note the disk number of the GPT disk.

Step 3. Type select disk #, and Press Enter. (# means the GPT disk)

Step 4. Type clean and press Enter, and it will delete all the files on the disk.

Step 5. Type convert MBR and press Enter.

Step 6. Type exit to close Command Prompt.

In a word, it is believed that you can fix your problem via the two methods. Now you can have a try. Good luck.
