you should also do
bootsect /nt60
If that doesn't work, from here. Please don't blame me if you cannot boot after this!
- Run a cmd.exe process with administrator privileges
- Run diskpart
- Type: list disk then sel disk X where X is the drive your boot files reside on
- Type list vol to see all partitions (volumes) on the disk
- Select the EFI volume by typing: sel vol Y where Y is the SYSTEM volume (this is almost always the EFI partition)
- For convenience, assign a drive letter by typing: assign letter=Z: where Z is a free (unused) drive letter
- Type exit to leave disk part
- While still in the cmd prompt, type: Z: and hit enter, where Z was the drive letter you just created.
- Type dir to list directories on this mounted EFI partition
- If you are in the right place, you should see a directory called EFI Type cd EFI and then dir to list the child directories inside EFI
- Type rmdir /S ubuntu to delete the ubuntu boot directory
