Windows 10: Bootrec fix/mbr marked as incorrect function.

My laptop is missing the winload.efi file. I have gotten to CMD though, and am trying to use the bootrec fix/mbr command yet its marked as an incorrect function. I'm not very good with technology but I haven't been able to find anything regarding the command being listed as an incorrect function, most people had access denied.

Fix Windows 10 MBR

Windows 10 MBR is broken! I tried reinstalling the operating system but no work. It always shows: 0xc000000e (winload.efi). I tried these commands with the command prompt built in with the installation media:

1. bootrec /fixmbr
2. bootrec /fixboot
3. bootrec /RebuildBcd

Although it says "The operation completed successfully", the blue screen still loads up. I don't have a system restore point already. Can anybody help???

 

Access denied on bootrec /fixboot


These are the commands and how to run them. No reason you should get Access denied.

Windows 10 MBR boot - bootrec /rebuildbcd says "requested system device cannot be found"

During the cleanup after building my PC I managed to break my Windows installation and I can't figure out how to fix it without starting over.

I have a Samsung 960 M.2 SSD in an Asus Strix X370-F and 2 sata HDDs. I've installed Windows 10 pro on the SSD from an old DVD via a USB DVD drive. I've accidentally booted the DVD in legacy mode instead of UEFI for the install, and it formatted the SSD in MBR. For some reason it also formatted one of the HDDs in MBR and made a 500-ish MB system partition on it.

After setting up everything, I nuked the HDD and reformatted it as GPT with a single partition, deleting the system partition. So now I have an MBR SSD with the OS and a recovery partition and 2 GPT HDDs with some user files, but nothing related to the system.

The PC comes up with a blank prompt. I tried running the boot recovery from the DVD both booting it as UEFI and legacy but it did nothing. I tried bootrec /fixmbr and bootrec /fixboot, they completed successfully, since then I get missing bootmgr at boot. I tried bootrec /rebuildbcd, it finds the Windows install but then says "requested system device cannot be found". I tried the suggestion to export and delete my bcd first but that failed too, I don't even have a boot folder.

All guides I find for next steps suggest to create an EFI partition but I can't do that on an MBR drive. What can I do instead?

Thanks a lot!
