# Revision history [back]

I finally did it!

And here is how: I went back to the Windows recovery stick. Within the "Advanced options" i choose "Command prompt" and ran:

bootrec /rebuildbcd


After reboot a "Windows Boot Loader" entry appeared (in the uefi-menu which opens if i hit F11 at startup), but furthermore i only got a short black screen followed by a fall back to the uefi-menu. Again totally clueless, i thought let's try this mysterious "Startup Repair" again and this time it did its job!

@Samuel If you're curious here is my current "fdisk -l" output, still no efi partition on sdb.
