ren c:\boot\bcd bcd.old > the system cannot find the file specified after clean boot

_{Tuesday, March 20, 2018 5:59 AM}

This computer had a clean boot in the past 30 days.

It is being used to test commands to be used on a computer that has a failed boot.

The command:  ren c:\boot\bcd bcd.old

displayed the system cannot find the files specified.

How does this get troubleshooted?

The directory of c:\   displayed:

EFI

program files

program files (x86)

users

windows

windows.old

bcdbackup

bcd_backup

test run bootrec rebuildbcd.txt

1) How come it cannot find the file specified?

bcdedit /export C:\BCD_Backup

displayed:  The operation completed successfully.
c:
cd boot

displayed:  The system cannot find the path specified  (How come it cannot find the path?)  Is there a syntax problem?

attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /RebuildBcd

from the Boot Configuration Data Editor Frequently Asked Questions: 

EFI–based operating systems. The BCD registry file is located on the EFI system partition.

So how do you fix a boot problem when it displays the system cannot find the path specified?

What is the command for the proper path?

The EFI partition is by default hidden.

The EFI partition was labeled b.

All of the commands on other links indicated that in the windows RE that disk 0 and C: where the methods to use for the command.

Running dir on b displayed:  1 dir 74,362,880 bytes

bootrec /fixmbr 

displayed the operation completed successfully

bootrec /fixboot

displayed the operation completed successfully

bootrec /scanos

displayed total identified windows installations: 0

bootrec /rebuildbcd

displayed total identified windows installations: 0

attrib bcd -s -h -r

displayed file not found

changing the drive back to X:

attrib b:\boot\bcd -h -r -s

displayed path not found B:\boot

attrib C:\boot\bcd -h -r -s

displayed path not found C:\boot

In b:

ren b:\boot\bcd bcd.old

displayed the system cannot find the file specified

In c:

ren c:\boot\bcd bcd.old

displayed the system cannot find the file specified

So what is happening?

How come none of the commands are working in C: or the EFI labeled B?

You seem to be calling commands for files and directories which are not existing on your system?
Aren't the error messages clear enough?
Its probably "b:**\EFI\Microsoft\**Boot\

I never needed to fix a EFI boot system, but google finds this:

Thank you for your less than helpful and facetious response.  Why even bother if you are no help?
