The same problem appears when the Windows installation on disk is configured for UEFI boot, but the repair process is attempted from commands stored on a USB drive which has been booted in non-UEFI ('legacy') mode. After whole day of efforts finally I tried it with DVD and it worked. Although it booted from the USB drive image due to some reason it was not able to start up the installation process. From this post I learned and realized the Windows 7 PE does not recognize USB drive. Update: I had hard time even reinstalling windows on my laptop. Update: Another user (improvedcomputers) contacted me to confirm that this also happened to them as all their USB slots were unrecognized by Windows 7 PE they ended up having to pull the drive and perform the repair on another computer. To make matters worse, I later discovered that it was by plugging in the wrong slot and allowing the rescue environment to attempt auto-repair that I messed things up in the first place! By plugging it into a different (usb 2.0 instead of usb 3.0) slot, the standard repair actions worked fine. I spent two days pulling my hair out, wrestling with this issue (the BCD store was ALWAYS unavailable with this 'The requested system device cannot be found.' error, no matter what I did), only to find that the problem was simply the USB slot I was plugging my bootable USB stick in. This error can happen if you are booting from a USB stick, and your BIOS supports a given usb slot, but the windows PE/repair environment does not!

Not directly related to your issue as you resolved it, but rather to your original description (particularly 'The requested system device cannot be found.' on BCD operations despite all attempts to recreate/rebuild): I'd like to avoid having to reinstall Windows since all the files on disk seem to be fine. It fails with similar message: The boot configuration data store could not be opened.ĭoes anyone know what does that error message mean, and what is the requested system device?

Many Google results say that I must use diskpart to set my partition active, however it's already set as active. The requested system device cannot be found. it fails with the following error: The store import operation has failed. When I type the following command as in the tutorial: bcdedit.exe /import c:ootcd.temp I've tried all the methods detailed here (including Windows repair which fails), and I'm left with the last one (near the bottom of that page). It seems that something is wrong with my /Boot/BCD, so I'm trying to recreate it from scratch. Info: an error occurred while attempting to read the boot configuration data. Insert Windows CD and run a repair your computer option.

A recent hardware or software change might be the cause. What I cannot do: I cannot boot into Windows - I get this message: Windows failed to start.

Although automated Windows repair fails, I can get to command prompt when I boot Windows install from USB drive, and I can see my drive and all my data. What I can do: I can boot Windows install from the USB drive, and I can boot the Hiren's Boot CD.

NVIDIA drivers upgrade crashed my Windows 7 installation, so I'm working to undo the damage.
