Bootmgr missing

[chimimoryo]

I was able to quickly restart in safe mode before the blue screen would kick in. I ran crystal disk in safe mode and there is nothing wrong with the drive.

 

What's the best way to backup my stuff in this situation? Is there away to do a nondestructive reinstall?

[chimimoryo]

So far in safe mode 

• DISM.exe /Online /Cleanup-image /Restorehealth - - no problems
• sfc /scannow - - no problems 
• Bootrec /fixmbr - - no problems 

 

What am I missing? What else can I do?

Is it possibly a motherboard thing? I found this page about bcd recovery followed it and it worked

But then I restarted my computer, windows booted. Blue screened, and now the c drive isn't recognized anymore. 

 

Why would that drive go missing after windows trying to boot every time?

The recovery console is.  Not 100% sure about safe mode with command prompt.

I'd wait on that m.2 reader if you can.  And if you have another machine to use to back up your files, that will help.  Are you able to read the error code thrown in the blue screen, or does it disappear immediately?

It stays for a while and displays a qr code. The error was just words similar to the linked the qr code took me to

Now after the latest attempt at bios flash, the boot m.2 isn't recognized initially again. 

Google search says hardware b

Problem, drive, motherboard, drive controller, and or cmos battery. How to trouble shoot?

Now the bios is freezing when trying to boot from usd to enter safe mode

My motherboard shows a post code of 42 when it freezes

A failing drive is the most likely of several explainations.

Your boot manager was probably set on one of the HDDs.

Best advice is nuke it and start over.

Wait, what's the problem? 

 

Thank you for trying to help me. 

My m.2 usb reader came today and my boot drive could not be read in my htpc. I had that lexar drive as a spear drive and tired that in the reader. It was read. 

 

Therefore then the sabrent 4.0 I was using as my boot drive appears to be the culprit. 

 

After everything I was doing to try and save the drive, I couldn't. I just couldn't accept that if I could go into safe mode and run diagnostics that the drive would be bad. But after not even being able to get past bios I knew something hardware was to be blame. Just glad it isn't the motherboard. 

 

Again thank you all for your help.

Heck of a journey. Sucks that the drive was dead, but I hope you learned some useful stuff!
