Yes, it is still not booting into Windows, but it has been a couple of days since I have had a chance to be in the office.

 

This is what i see when i do the list disk command

Hi robkbriggs

 

For some reason the 260MB Fat32 System partition is not been assigned a drive letter can you please again execute below commands and if you can post the results of the commands.

Diskpart

Select Disk 0

Select volume  5

Assign Letter=W

Exit

bcdboot C:\Windows /s W: /f  ALL

bootrec /scanos

bootrec /rebuildbcd

It seems to have taken the letter W, but it still is not finding an OS.

At the Command Prompt, type below commands as shown and then press Enter:

 

Diskpart

Select Disk 0

Select volume 5

Assign Letter=W

Exit

bcdedit /export C:\bcdbackup

The bcdedit command is used here to export the BCD store as a file: bcdbackup. There's no need to specify a file extension.

The command should return the following on screen:
The operation completed successfully.

Meaning the BCD export worked as expected.


At this point, you need to adjust several file attributes for the BCD store so you can manipulate it. At the prompt, execute the attrib command exactly like this:
 

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

What you just did with the attrib command was remove the hidden, read-only, and system attributes from the file bcd. Those attributes restricted the actions you could take on the file. Now that they're gone, you can manipulate the file more freely - specifically, rename it.

To rename the BCD store, execute the ren command as shown:
 

ren w:\boot\bcd   bcd.old

Now that the BCD store is renamed, you should now be able to successfully rebuild it.

Try rebuilding the BCD again by executing the following, followed by Enter:
 

bootrec /scanos
bootrec /rebuildbcd

If there were not errors restart your computer after rebuilding the BCD store. If there was error when executing any one of the commands please post the error message.

Is it possible that something is wrong with that volume? After rebooting, when going back into diskpart, it's not keeping the drive letter. If I assign it and do the list volume command again, it shows the letter, but if I restart, then it's no longer there.

Can you please post a screenshot of below commands.

Diskpart

List Disk

We might need to create a new System partition but i need to know which disk partition type you are using and List Disk will help me find that information.

Lets first set the Fat32 partition type and see this will resolve the issue.

Diskpart

Select disk 0

select volume 5

set id=c12a7328-f81f-11d2-ba4b-00a0c93ec93b

exit 

Restart your computer to see issue resolves.

This is the output I received from entering the commands.

Microsoft Windows [Version 10.0.14393]

X:\windows\system32>diskpart

Microsoft DiskPart version 10.0.14393.0

Copyright (C) 1999-2013 Microsoft Corporation.
On computer: MININT-F72ONCM

DISKPART> list disk

  Disk ###  Status         Size     Free     Dyn  Gpt
  --------  -------------  -------  -------  ---  ---
  Disk 0    Online          465 GB  1024 KB        *

DISKPART> select Disk 0

Disk 0 is now the selected disk.

DISKPART> select volume 5

Volume 5 is the selected volume.

DISKPART> set id=c12a7328-f81f-11d2-ba4b-00a0c93ec93b

DiskPart successfully set the partition ID.
 

After restarting the PC, it's showing the same issue as before.

after issuing the DELETE PARTITION OVERRIDE command, it came back with an output of;

 

Diskpart successfully deleted the selected partition.

 

Would you like me to continue with the rest of the commands?
