Can you manage to migrate the application into the bootable USB? Otherwise I would buy/borrow another drive, clean install and try to unformat your current drive.

IS THERE ANY DATA-LOSS AT STAKE HERE?

Cheers

Can you explain it more clearly.

Noop.
It has also not worked

how many partitions do you have into your disk? If you make backup of data you want to store using a Linux live CD or Hiren's Boot and saving data to external HD/USB, then you could try to remove every partition into your primary disk and let windows partition when you choose the installation drive; that should work, but remember to backup data, if any, because that would wipe everithing!

You stated you ACCIDENTALLY formatted your drive! My simple Q is:

IS THERE ANY DATA-LOSS AT STAKE HERE?

Hope this helps.

Cheers

I dont think so there was any important data on C drive except windows.

Thanks for the help but I had alredy seen that and the problem is while selecting upgrade option it says'The computer started using the windows installation media and needs to be restarted.'

And while selecting custom(advanced) it says ' The windows cant install on this disk. The disk has an MBR partition table . On EFI systems , windows can only be installed to GPT disks.

When you get to the first screen in Windows setup, press shift+F10 to open a command prompt window. Run the following commands - NOTE this will erase anything left on your hard drive!:

diskpart
select disk 0
clean
convert gpt
exit
exit

Then proceed with the custom install.

Thank you very much @NavyLCDR I tried it and it eventually worked .
Thanks again.
