I reset my boot manager, easyBCD warn me that I should add boot options and I add drive C option. So I was wrong and now I have fully functional and installed Windows 10, but I just can't boot in. So there is the question, in bios (Asus) I have option: add new boot, and possibility to add boot path, I found some .efi files like bootmgfw.efi fbx64.efi bootx64.efi.

Any chances that this files are not corrupted and I can booting with them?

Or there is no chance and I just need to make another windows image and install/repair it? And now I have Ubuntu live USB by my hands, so maybe I have another options? I don't need any data.

  • You just need to restore the boot loader. Nothing is needed in the BIOS. It is automatic. dell.com/support/article/us/en/04/sln300987/…

  • @Appleoddity could I do that process with Ubuntu live USB? I assume I need to burn windows image for this

  • It’s just as easy to make a windows USB so I would recommend that.

You simply need to add the path to bootmgfw.efi as the boot option. This is the default Windows 10 Boot Manager file for EFI systems. bootx64.efi (or bkpbootx64.efi) is a copy of bootmgfw.efi and is used as the fallback boot manager if anything were to happen to the original one.

The path should (you have to check for your case, not blindly copy/paste) be something like the following:

/EFI/Microsoft/Boot/bootmgfw.efi or /boot/EFI/Microsoft/Boot/bootmgfw.efi (most probably the first if no other OS has been installed on the system before that).

And yes, those files are most likely to be safe and not corrupted.

Edit:

As you reply that using the path to the boot manager does not work, I can only suggest you to either repair by using a recovery windows image (as stated in comments by @Appleoddity), or just install your Windows again from scratch, since you don't need any data.

  • When I try to use bootmgfw.efi file as a path for boot, and use it screen go black for a few seconds and that's all I'm staying in bios.
