I used to have ubuntu installed in pc hard disk but for other purposes, I can have only windows installed. Now I have uninstalled all partitions having ext4 fs, so only ntfs and bootable fs (vfat32 I think) remain. But still, when I boot I see grub bootloader (GNU GRUB version - Minimal BASH-like line editing is supported. For the first word, TAB lists possible command , …). Now I would like to remove this as well. I have tried to go to recovery mode, and from there to command prompt: bootrec.exe /fixmbr and then bootrec.exe /fixboot but access denied (I do not know why), but neither helped - I am still entering the grub. I do not have any media with full windows installation so I cannot boot from usb and make full install (I have tried although full restart which reinstalled the whole windows - still did not helped). So How can I delete/remove the grub bootloader from master boot record (or wherever it resides) to boot directly to windows?

PS: to get from the bootloader, I have to at least twice exit from the bootloader, when it finally boots windows. How to delete the bootloader?

  • You need to make sure Windows boot loader is default in UEFI. You should always have a Windows repair disk or installer with repair console. Also depends on whether grub is UEFI or BIOS & whether Windows is UEFI or BIOS and if system is set to boot in correct boot mode for install. If UEFI, you typically remove the UEFI boot entry and the /EFI/ubuntu or /EFI/grub or whatever Linux you had. But do not remove /EFI/Microsoft in ESP - efi system partition.
