Actually I was formatting my Dell Vostro Laptop. And while doing that a message showed up that "you cannot install OS in this partition. The selected disk is of the GPT partition style." I have search the solution in technet.microsoft.com and one answer i got is to "To manually wipe a drive and convert it to GPT: " and solution found is
From inside Windows Setup, press Shift+F10 to open a command prompt window. Open the diskpart tool: diskpart Identify the drive to reformat: list disk Select the drive, and reformat it: select disk clean convert gpt exit
And after that when i opened custom installation type. I found that all my hard disk got unallocated.
Kindly provide me solution to get my Partition table back or any solution to recover my data.
Please help me. And thanks in advance.
