An attempt to restore Windows 7 EFI boot record with bcdboot c:\Windows /l en-us /s f: failed with

BFSVC: Failed to create a new system store. Status = [c000003a]

Does anyone have a clue what this error code stands for (search did not help)?

For those interested boot failed completely after the restart which followed trying to change the paging file to another drive (an SSD one).

  1. I tried changing EFI partition type to another random one with "set id=..." described in superuser.com/questions/725322

  2. tried all bootrec commands listed in superuser.com/questions/891804

  3. tried various bcdedit commands described in other posts.

What else can I do to get it booting again?

A few years ago, I was having a problem like yours and it turned out that an anti-virus program had disabled automount. The fix for my system was: Open a command prompt with administrator privileges. Or in your case, from Win RE.

type "diskpart" (without the quotes) and press enter.

when the 'diskpart' prompt appears, type: "automount enable" (again without the quotes) and press enter.

"exit"

I don't remember if a reboot was needed, but it wouldn't hurt

Good Luck, I hope this helps.
