had windows and i wanted to use 2 OS using boot i installled Kali Linux, I removed it after a few hours, but I forgot to remove the grub boot loader. I tried multiple wats to change the boot system from bios but if i even change one seeting from bios it just gets freeze and I tried holding down the power button for a 30 seconds and restarting, and doing the same thing, but it still freezes when switching to the Windows boot loader.
