Windows 10: "Your PC/Device needs to be repaired" Error 0xc000007b

Yeah, I understand you're trying to get me in Safe Mode. I'll try this in a bit. Also, if I clear the CMOS on the motherboard, it may help?

 

I'm in cd/windows now. It says X:\Windows>

 

You need to list your disks to figure out which drive letter corresponds to "the drive normally known as C:." That's because drive letters don't always (or rather, seldom, if ever) match drive letter assignments in the normal boot environment. Thus, when I boot into recovery, I usually find my drive by using the Windows Management Interface Command (WMIC) utility as follows:
1. Open a command prompt with elevated privileges
2. Type wmic at the command line. It has its own shell just like diskpart and other complex CLI utilities
3. type logicaldisk get name, volumename

Now you can figure out which drive is which. Here's a (hopefully) illustrative example:




And of course, you'll need to type "exit" to leave the wmic cli when you're done, after which you can terminate your command line session, if you choose.

"'wmic' is not recognized as an internal or external command, operable program or batch file."

 

Bizarre! I just tried it with kyhi's recovery disk and it works fine for me. OK, there's another way using diskpart. Here goes:
1. Fire off the admin command prompt.
2. Type diskpart
3. Type List volume
Here's what that looks like:




This should work in any kind of command line environment (goes back to DOS days if memory serves). Sorry for your trouble!
HTH,

It looks like this now: Imgur: The most awesome images on the Internet Also, by the looks of it, do you believe there's hope of getting my system back together? *Sad

 

And, if it all comes down to having to re-install Windows, will Windows 10 keep my product valid? I have a genuine product (originally Windows 7, but upgraded to 10).

 

Yes, I think you can put your system back in working order. And yes, if you activated your upgrade based on a Windows 7 license and associated it with an MS account, your activation data (and PC) is already in the database so when you perform a clean install that should activate automatically. Keep trying!

I didn't really associate it with a MS account, but I have the Windows 10 product key (and Windows 7 one, on a sticker) noted down somewhere, if that helps? And thanks, I'll keep trying, is there anything else I can try to maybe troubleshoot? It seems like the BCD file is missing also now so there are even more problems in the system...
Do you think this guide How to Fix Error Code 0xc00007b in Windows 10 - YouTube can help?

 

I do not think so, because I thought we had determined that the issue is because of the graphics driver?

 

It is yeah, but the graphics driver doesn't seem to be the only corrupt thing...it maybe broke something else with it?

 

Well, the BCD rebuilding is what has already been done if I'm correct.
In this post, the ISO is from Macrium Reflect which you booted and used the 'fix Windows boot problems' option that rebuilds the BCD.
You could try it again, this time on the Windows partition, if you want of course.

 

It seems like this "fix" broke the BCD, maybe because the Windows 10 build is maybe different? Also the boot fixing didn't complete successfully if I remember correctly; the one before the last had a red X near it when I tried it on the Windows partition.

 

The "Updating Partition Boot Sector" has a red X near it in the boot fix process.

 

You never mentioned that the fix failed, at least not specific enough because I had the intention that there was nothing wrong.

There are only 2 methods for booting which have nothing to do with the Windows build, they have been the same for many Windows builds.

Now that I know that Macrium hasn't worked, try to manually rebuilt the BCD *Smile
