A device which does not exist was specified.

Question

I have Windows installations on two different drives, both working at one point. However, now I can't boot into one of them. Whenever I try to access files on that one while booted into the other Windows installation, I get this error: "{File Path} is not accessible. A device which does not exist was specified." If anyone knows how to fix this so my drive works without reformatting, their help would be appreciated.

Event Viewer Shows "An error was detected on device \Device\Harddisk0\DR0 during a paging operation." Event ID 51 about a zillion times.

Things I've tried so far:

chkdsk

sfc and dism from recovery

startup repair from recovery

Hello,

Here are a few additional steps you can try to resolve the problem:

Check BIOS/UEFI Settings:

Ensure that the drive you are trying to boot from is set as the primary boot device in the BIOS/UEFI settings. Sometimes, the boot order can change, causing boot issues.

Update or Reinstall Drivers:

Update the drivers for your storage controllers. You can do this from the Device Manager in Windows. Look for any devices with a yellow exclamation mark and update their drivers.

Check for Hardware Issues:

Ensure that all cables connecting your drives are secure. Sometimes, a loose connection can cause the drive to be inaccessible.

Repair Boot Configuration Data (BCD):

Boot into the recovery environment and open Command Prompt. Run the following commands:

bootrec /fixmbr

bootrec /fixboot

bootrec /scanos

bootrec /rebuildbcd

Hope this helps.

Best Regards,

Hania Lian
