In this post, we will show you how to fix error A required device isn’t connected or cannot be accessed with codes 0xc0000185, 0xc0000225, 0xc0000001, 0xc00000f, 0xc000000e on a Windows 10 system. We have recommended below a few solutions, depending on the error code and the system.
A required device isn’t connected or cannot be accessed
All of these errors point to the same thing. The PC needs repair. It happens mostly when the computer is not able to find the system files to boot up the computer. The only way to fix this is to correct the boot record.
We recommend that you use /RebuildBCD option to rebuild the BCD. If that doesn’t help, there is a crude way to rebuild the boot record from scratch. The steps below will export and delete/backup the BCD available on the system. Then when we again rerun the program, it makes sure that the BCD store is completely rebuilt.
In the Advanced Recovery Mode, execute these commands one after the other in the Command Prompt.
bcdedit /export C:\BCD_Backup
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old

If nothing works, you may want to reset Windows 10 using the recovery tools.
