It all began when I deleted the partition of an old Linux that was dual-booted with Windows 8.1 UEFI. This Linux system was using the Grub2 bootloader and was installed on a secondary disk.
After rebooting grub was thrown in the rescue shell because it probably could not find it's files that were on the deleted partition.
I tired to fix the issue by booting off a Windows 8.1 CD (booted as UEFI) and attempting various things:
Automatic startup issue fixing from recovery options. This failed.
Executing
bootrec
with/fixboot
and/fixmbr
. This said that it completed, but did not change anything.Executing
bootrec /scanos
. This said that there were 0 Windows installations found. As a resultbootrec /rebuildbcb
did nothing useful aswell.Manually rebuilding the BCD. Assigned the EFI partition to drive letter V: and deleted the contents of it (it still contained files from grub). Then executed
bcdboot C:\Windows -l de-DE /s V: /f ALL
. This was successful and actually did change booting behaviour, but gave me the error below.
How do I boot into Windows again?
The bootloader error:
Your PC Needs to Be Repaired
The application or operating system couldn't be loaded because a required file is missing or contains errors.
File:\Windows\system32\winload.exe
Error code: 0xc000000e
You' ll need to use the recovery tools on your installation media. If you don't have any installation media (like a disc or USB device), contact your system administrator.

Did you try running Startup Repair again after getting this latest bootloader error? – Karan – 2015-06-11T15:05:36.937
@Karan Yes I tried that, but it still fails. Looking at the logfile
SrtTrail.txt
it does not show any errors. Bottom line says that it succeeded starting the OS. – typ1232 – 2015-06-11T15:14:29.053
