Error 0X800701B1 - how to fix it?

Hi! Really hope you could help me solve the problem

My problem was with a secondary hard drive controller with a Marvell chip.  I swapped out the controller and my problems disappeared.  I'm not sure what you can do with a USB drive.

Hi Gabriel,

I am Sumit, an Independent Advisor and a 2-Year Windows Insider MVP here to help.

The error code means a device which does not exist was specified.

It looks like the hard drive is wearing out.

Download and run HDTune .

Select the external hard drive.

Make screenshots of the following

Post back the screenshots.

look at your partitions. if you have a #2 partition on the internal hard disk, it will say, "To do this, I am pointing to your DVD/CD. "  And the partition is corrupt.  in ' gparted '  you can see your disk partitions.

And, you can use ' Diskpart ' in windows from an command line, or WinPE X:\ environment.

I had a dvd problem, HP GUB0N  said it could not format/erase/write to dvd+RW.  Well, I had a stack, and I thought I had made backup of the system first thing, but nothing is on them.  The cd/dvd drive takes  cd-r, cd-rw, dvd-r, or dvd-ram disks... 

Installing upgrade from 1809  to 1909, I have tried all manner of ways with the same result. fail.

The drive suddenly blue-screens, with " I got no device" x0c000001..

So, I look, and the MSR partition (my #2 part) is red.. corrupted. 

What it wants is a cd-rom..boot disk from the factory.  If you do not have one, try bcdboot with care!!!

be sure you got all data off.. and do not want the c:\windows.    bcdboot can tell you things also... like, the GUID numbers of the boot devices, and order of boot..

My problem is, why does this say my disk 0, is not the correct thing.  And why the system put that 0 is my cd-rom?   I am not sure, but.. the upgrade installs have been with directions from microsoft to do that.

I suspected a driver, but maybe it was this corrupt partion that made my installs fail..
