Windows bootloader gone

Anonymous

HI, since i updated to windows 11, the windows bootloader option disappeared from my bios options to boot. I have dual boot with ubuntu and the only way to access windows is by the grub. I want to uninstall Ubuntu, but i'm afraid it can cause trouble. I've tried repairing the bootloader but it shows an error at trying to copy my boot files. I've also tried using EasyBCD, but my bios is set-up as UEFI, so I can't do a thing. I don't know what else to do, please help. My disks are GPT, both of them.

This are my partitions, the one on top is the main disk, a ssd, and the one below is for storage, HDD. The only critical partition is the Disk 0 partition 6 (EFI File). The rest of them that have no letters assigned are from Ubuntu. In advance, thank you.

Answer 1

Windows Boot Manager will appear in a UEFI install during install from media booted as a UEFI device, when you clear the partitions the partitions to reset the formatting and then set up your partitions, or choose the Unallocated Space and click Next to auto-create and format the needed partitions and begin - this makes it foolproof.

When you installed Windows to that system, or it was installed at the factory, it should have triggered the WIndows Boot Manager, so something done subsequently with the Ubuntu dual boot GRUB boot manager must have gotten rid of it.

This is why I gave you every Linux dual boot removal tutorial I could find that exists on the internet, because there are that many things that can go wrong when trying to recover Windows after removing Ubuntu. You may need to reinstall Windows, making sure (again) to delete all partitions off the drive, choose the resulting Unallocated Space and click Next to auto-create and format the needed partitions and begin which makes it foolproof.

Looking further, other tutorials for removing Linux Dual Boot and recovering Windows here:

You can also try creating the EFI System partition from scratch to see if that fixes it:

Another method I sometimes use to save a stranded Windows 11 install that's lost it's boot partition is to do a Rescue install to another partition, which will configure a Dual Boot between the two. If the old WIndows partition will start then you can boot into it and delete the rescue install (and it's boot listing in msconfig > Boot) and have a new working EFI System partition.

Feel free to ask back any questions. Based on the results you post back I may have other suggestions if necessary.

Hi, I read all of them none of them helped me. The only thing I want to do know is to make the Windows Boot Manager an option in my BIOS. I only have the option to boot into Ubuntu, but not to windows directly. The windows boot manager is located in the partition #6 of my SSD, but o don't know why it is not an option in the bios but it is in the GRUB. I've tried all of the methods but none of them work.

What are the present BIOS options? For UEFI first boot prioirty should be Windows Boot Manager or the windows UEFI hard drive.

The tutorials I gave you show everything needed to remove Ubuntu from a dual boot and repair Windows boot loader so it starts. Did you read them?

Thank you, deleting ubuntu is easy, I just stopped from doing it because windows bootloader isn't an option on my bios settings. Once I delete the ubuntu partition, automatically the grub would disappear and my pc will run into windows?

Hi Rax. I'm Greg, 10 years awarded Windows MVP, here to help you.

When you have separate hard drives it's much better to install Windows and Linux each to its' own HDD and then boot them independently via the BIOS Boot Menu key. This avoids problems like you have now needing to extricate Linux from the system while saving Windows.

Try these fixes for removing Linux from Windows dual boot with WIndows 10 or 11 (the fixes are the same for both):

One of those should work. If not report back all results so I know what else to suggest.
