Or you can try them so that you can boot either way, BIOS or UEFI, but then you need a copy of the BCD on the Windows partition (for legacy) and not just in the EFI partition (for UEFI). If you're booting using UEFI instead of Legacy (BIOS), then I think you should skip the /fixmbr and /fixboot options. The makers of EasyBCD have documentation to help do this. The BCD should contain at least one entry that points to the Windows partition. Boot the installer, repair, command prompt, mount the EFI partition of the disk containing your Windows partition if it's not mounted already, and recreate the BCD. Yes, repair this with the Windows installer. If you got bootmgfw.efi from the EFI partition, then the BCD would be there already.

Only problem: I originally setup the system years ago and that ancient “WindowsSupport” package and the corresponding setup.exe/MSI package was long gone. So now my idea was to find the old MSI package from the existing installation and uninstall it through that. When I tried to uninstall the old drivers through setup.exe of Bootcamp (the new one I downloaded with the WindowsSupport stuff from Apple) the program declined the action and was referring to an older version of the software that I wanted to un/install. exe file is located.įor me it’s located at: C:\Windows\system32\BootCampService.exeĪfter stopping the service in the previous step, I easily could delete the exe file.
