For boot failure this Microsoft link displays:
To do this, type the following commands at the Windows RE command prompt:
- bcdedit /export C:\BCD_Backup
- c:
- cd boot
- attrib bcd -s -h -r
- ren c:\boot\bcd bcd.old
- bootrec /RebuildBcd
How do you troubleshoot failure of the above commands?
For example:
C:\cd boot
C:\boot>attrib bcd -s -h -r
File not found - bcd
C:\attrib c:\bcd\boot -h -r -s
Path not found - C:\bcd
The directory of C: displayed:
Directory of C:\
07/28/2018 02:28 AM <DIR> boot
The directory of C:\boot displayed
C:\boot>dir
Volume in drive C has no label.

K:\EFI\Microsoft\Boot>attrib bcd -s -h -r
K:\EFI\Microsoft\Boot>
Are these the correct commands to get the attrib command to work?
How come the attrib bcd -s -h -r command fails with the method displayed on the Microsoft webpage?
How come the Microsoft link does not indicate that the EFI partition needs to be labeled?
Please explain how to properly use the attrib bcd command if it regularly fails with the displayed commands?
Is the link only for MBR? Is that why it fails on GPT with EFI?
Or would it fail on MBR too?

Hi,
The link you provided applies to Windows 7 Starter, Windows 7 Starter N and Windows 7 Home Basic. Could you tell me what’s your PC version?
The correct command should be like this: attrib -h -r -sc：\ boot \ bcd**
Hope these are helpful.

There are multiple computers with Windows 10 version 1607, 1703, 1803, 1809, etc.
Would like to find the proper command for any computer with Windows 10 to troubleshoot boot failure with the proper attrib command.
The command that you posted was entered and this was the displayed result:
C:\attrib -h -r -sc :\ boot \ bcd
Parameter format not correct -
C:\attrib -h -r -sc :\boot \bcd
Parameter format not correct -

This post is not to troubleshoot boot but to get the correct command for Windows 10 using attrib.
There are many that have boot failure and the TechNet threads commonly display problems using this attrib command.

The attrib command fails for each GPT and MBR.
Are the problems related to the path?
Do the paths for the boot file and bcd file each need to be found before running the command as these commands consistently fail for for GPT and MBR:
Using GPT:
C:\cd boot
C:\boot>attrib bcd -s -h -r
File not found - bcd
C:\boot>
.
.
.
Using MBR:
C:\cd boot
The system cannot find the path specified.
C:\
Which path for the attrib command works for GPT?
Which path for the attrib command works for MBR?

.
The link that was posted refers to directories:
https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/attrib
.
.
This command regularly fails.
Is it because it is the wrong directory for Windows 10 GPT or MBR?
- bcdedit /export C:\BCD_Backup
- c:
- cd boot
- attrib bcd -s -h -r
- ren c:\boot\bcd bcd.old
- bootrec /RebuildBcd
.
.
.
Is this the proper path for GPT?
K:\EFI\Microsoft\Boot>attrib bcd -s -h -r
.
.
.
What is the proper path for MBR?
