code error 0xc000000f in windows 11

Hi Dominic,

I've had te same issue yesterday and I've tried many time to us the winRE method (with an extern usb Key with windows 11 installed on it). I've spend 8 hours but nothing bring me in to the recovery data. Everytime the system showed the same error. Well, I took apart both SSD drives (the were mounted in a mirror), take my old HDD and install win 11 on it. Now I've ordered an USB SATA cable on amazon, my idea is to connect it to the PC and after that I try to solve the issue from extern with the method that you have posted here. Thank you. The power went out here yesterday, and how often the case is, every time that the power was back I powered my pc on and on the same time that the boot was in action the power was again out. I mean this happens for 4 or 5 times. It's absurd. My question, did you met or heard my issue above in other cases? What is your proposal in that case if we have important files and preferable non want to loose them? This was the reason because I build a mirror system with to same SSD, but how often in Life ..the issues arrives suddenly from an other direction....Cheers Maras

Hello Rahim Marembo,

When you see 0xc000000f, the message usually references \Windows\system32\winload.efi and indicates that the system cannot locate or load the boot manager. This is not something that can be fixed from within Windows itself since the OS never loads. The proper approach is to use a Windows 11 installation USB or DVD. Boot from that media, select "Repair your computer," then go into Troubleshoot > Advanced Options > Command Prompt. From there, run the following commands in sequence:

Code

bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

These commands repair the Master Boot Record, write a new boot sector, scan for installed systems, and rebuild the Boot Configuration Data store. If bootrec /fixboot returns "Access is denied," you may need to run bootsect /nt60 sys first to reinitialize the boot sector. After completing these steps, restart the system and check if Windows boots normally.

If the error persists, it can indicate deeper corruption of the EFI partition. In that case, you may need to manually recreate the EFI system partition using diskpart and reassign it, or perform an in-place repair install of Windows 11. If the disk itself is failing, no amount of boot repair will resolve the issue, so it’s worth running chkdsk /f /r from the recovery environment to confirm disk health.

Since you mentioned you already tried "all options," I would clarify whether you have attempted the bootrec sequence from recovery media. Many users only try Startup Repair or Safe Mode, which do not rebuild the BCD. If you have already run these commands and the error remains, the next step is either repairing the EFI partition manually or reinstalling Windows 11 cleanly, depending on whether data recovery is a priority.

I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!

Domic Vo.
