How do I completely remove GRUB from secure-boot UEFI...?

I was dual booting between Windows 10 and openSUSE 13.2 on a Toshiba laptop with a secure boot UEFI setup. I have removed linux and the partitions. Grub remains. I can get around it but it would be cleaner to remove it. I’ve tried the bootrec commands in Windows but it doesn’t faze GRUB. It went on easy enough. How can I remove it?

If EFI then there is a small FAT formatted partition that holds the first stage boot code for all OS’s simply removing partition leave that… but you also have to remove the entry from the EFI BIOS’s flash also.

Simply remove the openSUSE directory from the boot EFI partition. How to do that from Windows Good question since Windows actively hides it from you.

I believe it is the 100mb partition. I’ve tried everything I could think of. Right now I have to hold down f12 when booting, choose the hard drive to boot from, select Windows and then tell Windows to boot Win 10. Then everything is fine till the next boot up.

You should be able to select in a bios screen what to boot by default,
and make it permanent. It depends on your machine.

If not, you could edit that efi partition from a Linux Live.
