Inaccessible Boot Device error in Windows 10

"The /SysDriveDir option specifies the path to the location of the BootMgr files."

Wouldn't the path you want to reference there also be the C: partition (or whichever letter the OS is designated to) rather than WinPE?  

Did I say it Ref WinPE, if so that would be a fau pau. However some 3rd party Recovery systems that have WinPE in them sometime embed themselves in the BCD and thus come up on the Boot Menu. I would NOT do that unless one has a separate System Recovery with centralized Boot Environment implementation on a partition(This the way I run). In my case it is called 'R' and is also where my WinRE files are, that way THEY ARE NOT on 'C'.

That is why one has "/SysDriveDir". 

On 'R' I have Backup Images extra BCD backups that I can copy over if the active one gets corrupted, etc....... It is quit custom. Some OEM Companies build a Recovery partition and hide it. Sometimes they put the Boot files on it as well. Then one need a facility to unhide...

If this is not similar to your configuration and every thing is on 'C' than you don't need "/SysDriveDir".

Ah, that's smart.  In my present case scenario, I have WinPE separately on a drive and only the native (upgraded) OS to the computer on hand.  That being the case, would the DISM commands look like the following?

"DISM /Image:C:  /WinDir:Windows  /SysDriveDir:C:\  /Cleanup-Image"

In other words, both directories pointing to "C:" (or in my case, having checked with Diskpart, "D:")?

Thanks! :)

PS I just went back and looked at Page 12 and what I wrote there(is that where you were looking,Dave?). Were you also meaning doing this in WinPE? If so sometimes one needs to get a bit more specific than one usually has to, in WinPE to get results. In other words sometimes I have noticed that one needs to state the obvious.....

For 0x8000ffff, I tried:

• Renaming ..\windows\winsxs\pending.xml
• Renaming ..\windows\SoftwareDistribution
• Renaming ..\windows\system32\Catroot2
• Set both  "Exclusive" and "TotalSessionPhases" data to "0".
• Mounted the Components registry file and removed some value(was mentioned in a Microsoft article, didn't archive the solution's steps).
• Ran DISM's /scanhealth and /restorehealth commands(tried a second time choosing a 1709 version Windows 10 disk "install.esd" file as the source).
• Ran chkdsk
• Ran SFC

Still getting 0x8000ffff when adding or removing packages using DISM. That computer is also getting the clean install treatment.

OKAY,

Here is what I found using Bing(because both are MS): "0x8000ffff".

Hello,

Thank you for your response. I appreciate your time.

If you are using third party security software, try disabling third party security software and check. Disable third-party Security Software.

a. You should see an icon for your Antivirus program in the Task-bar notification area. It is usually at the bottom right corner of your desktop.

b. Click on the third-party Security Software Icon, you will see a pop up.

c. In that pop and select the option to disable, click on it.

d. Now the third-party Security Software will be disabled.

Important Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other software, you should re-enable it as soon as you're done.  If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.

Sincerely,

Ankit Rajput

The problem I am finding is the nobody seems to be resolving it within MS. So now one need to go to 3rd Party sites....
