Windows 8 HAL.dll is missing or contains errors. EFI Boot

Hi
I've got a Dell Vostro here, EFI boot. Windows 8 and it has got stuck in a repair loop after a powercut in the office.
There's not that much info around about fixing EFI boot problems but I have tried what i know from repairing Windows 7 plus what little I have found online.
chkdsk says no problems,
sfc /scannow reports Windows Resource Protection cannot start the repair service.

and
http://think-like-a-computer.com/2012/04/17/boot-bcd-0xc000000f-windows-7/
also failed to work. Rebuildbcd seems to find the OS but gives a - The requested system device cannot be found when trying to add it...

Anyone?

I'm really suprised to see any business uses the infamous windows 8.


Try to reboot in safe mode. Safe mode will bybass many drivers.  What is the error in that case?

This is a bootmgr problem. So its the same in safe mode.

Try rebuilding the bcd

C drive... replace it with the drive that contains the os  and user files.

    bcdedit /export C:\BCD_Backup
    c:
    cd boot
    attrib bcd -s -h -r
    ren c:\boot\bcd bcd.old
    bootrec /RebuildBcd

Tried that before I posted, 'Rebuildbcd seems to find the OS but gives a - The requested system device cannot be found when trying to add it...'
Thanks anyway.

I hope the hard drive mode is set correct in bios

Make sure hard drive is set as first boot device in boot priority.

If chkdsk doesn't fix it, I'm afraid you're left with reinstalling the O/S from the recovery partition.

Very annoying as I know I could have fixed this if it was Windows 7...
