Uninstall grub2 when booting without secure boot (tried everything, nothing worked)



I used ubuntu and windows in dual boot and deleted ubuntu so I ended up still having grub2. When I install secure boot this prevents grub2 from starting and I can boot into windows. When I disable secure boot (for example to boot a liveCD of ubuntu) it starts the grub2 command line (I think it is emergency mode) and I cant boot anything. I tried everything:
I used a windows 10 repair dvd and used bootrec - didnt work
I used several programs including easybcd, mbrfix, dbr, etc. - didnt work
I tried using the bootsect in the cmd - didnt work
I tried using grub2 to boot windows - didnt work




What else can I do to get rid of it? If you need anymore information feel free to ask. Thank you very much for your help



If UEFI boot, you should just be able to set Windows as first in UEFI boot order.



But you may want to remove ubuntu entries from UEFI NVRAM/menu and /EFI/ubuntu folder from ESP - efi system partition.



How do I remove "Ubuntu" in the bios boot menu? (UEFI)



OR:




Can I remove Windows Boot Manager from dedicated Ubuntu computer?
