It did do the boot repair; the entry entitled
Windows UEFI bkpbootmgfw.efi should boot Windows. If it doesn't, I recommend you try the following procedure:
- Disable Secure Boot in your firmware. Unfortunately, the details of how to do this vary from one computer to another, so I can't be more specific.
- Use the Boot Repair tool again, but click "Advanced Options," check "Restore EFI Backups," and proceed. This will undo most of Boot Repair's "fixes," which obviously aren't working.
- In your regular Ubuntu installation (not in a live CD), download and install the Debian package version of my rEFInd boot manager.
When you reboot, the result should be an ability to boot either Windows or Linux (the latter, most likely, via at least two menu entries, one of which uses GRUB and the other of which is more direct). This procedure works for most people, but for some there are other complications -- unfortunately, subtle differences between EFI implementations, EFI bugs, and bugs in software can cause problems, and you've just got to deal with them on a case-by-case basis.
