Windows 10: I'm pretty sure my bootloader/manager is broken. How do I fix this? Please help!

Upon turning on my tablet PC I get a quick flash to the background of the screen, however, the screen always stays black. I can tell that it accesses the USB when I have my recovery media plugged into the port but I cannot access my recovery media . I can access the BIOS menu and change the settings in there that are available. I can load default settings. I have tried several combinations of settings in order to produce some kind of response that would allow me to reset Windows or get to some sort of Windows system screen giving me the option to troubleshoot but I have been unsuccessful.

How To Fix The Windows 10 Bootloader

THANK YOU. This solved it. I think this was mentioned earlier by you or someone else perhaps but I've messed around with it enough now where I vaguely understood what the commands were doing. I actually had to delete the partition, recreate it, and re write the BCD as you suggested in Step 3.

Shoutout to @topgundcp I'm sure that last method you suggested would have worked too, but now I understand how to do it manually, so I learned something.

Also, thank you @NavyLCDR for your help as well.

I have ONE last question, any SAFE way to remove the old ubuntu EFI entries that are present in my UEFI as boot options?

edit: Nvm, figured it out. For anyone else wanting to know how to remove old EFI boot entries, use "EasyUEFI" it is super easy. Took like 10 seconds after install. I DID have two identical looking EFI's for my samsung ssd, one of them, in the details, showed that it had no file path. I assumed that was my old broken one and deleted it, must have been correct bc my computer boots up perfect.

Thanks!!!

 

Broken window boot manager

Hello Danny,

We regret for the inconvenience. Before we conclude that the Windows Boot Manager is broken, we need to see if the issue is related to Windows at all.

Now, this issue might happen, if GRUB can't find its requisite files. This can have numerous issues.

In this case, we need more information about your system, especially which hard drives or solid state disks are installed in your computer and how they are connected.

Few more details we need to know are as follows:

• What do you mean when you say 'I missed a step on resetting everything'?
• On which drive you installed Ubuntu and (if you know) on which you installed the bootloader?

There is a chance that the grub installation on your hard drive is broken. In that case, you need to update/repair grub using Ubuntu live CD.

Write to us with the required information for us to be able to assist you further.

Thank You.
