Mine is Dell xps 13 ultrabook shipped with windows 7. I thought of installing ubuntu, so I unknowingly deleted recovery partition, formatted it and installed ubuntu. Now ubuntu is working fine. But in grub, I am not able to see windows. So I followed this tutorial How to Manually Repair Windows 7 Boot Loader Problems - How-To Geek
to fix my windows. But it didnt work
In second screenshot, Windows 7 option didnt appear. I clicked next and did Startup repair which didnt help and then went to command prompt to execute the two commands
The first command executed successfully but the second command gave me an error "the volume does not contain a recognized file system"
How can I recover my windows . Please help. I need windows badly
