problem with bootleg

you never know what it may have done. too many nasties hide in them. normally if win7 was the original os that came with the computer is all you have to do is to delete the win8 partition then use a utility such as bcdeasy to fix your bootloader. that is the easiest way.

Re: deleting a partition

That's easy. Any partition manager can do that, even Windows 10 own disk manager. But it's possible the boot procedure still needs something from that 8.1 partition. So first make a recovery drive from Windows 10, so you can do a startup repair if needed.
