 ====== Fix the Windows boot process ======
-Why is this page here?  2 reasons...   First:   We have seen clients bring in Windows 10 computer that would not boot or would not successfully "fix the boot process" using the Windows 10 recovery environment.   Second:   It is possible to use the process below, as the final step in "cloning" if you do not have a cloning tool.    The process assumes 2 disk drives.     On a new drive, install Windows 10.   Next, using Clonezilla or RescueZilla or ???, copy the Windows partition from the old drive to the Windows partition of the new drive.    The result is likely to be that the new drive will not boot.    The process's below can fix the boot process on the new drive.

 Warning!! Understanding and/or fixing boot failures is tedious, aka "lots of details". Be careful!!!! If you want to understand the details of the Windows boot process this [[https://www.youtube.com/watch?v=Q0R_CXArPd8&t=225s|youtube video]] is a good starting point. It is about 20 minutes long and full of details. If you just need to repair a boot failure,[[https://www.youtube.com/watch?v=sOihh4ZNOf4&t=307s| this video]] may be what you want to watch. The cliff notes for the video are: From a "cmd" window, use diskpart to assign "C" to the Windows partition. Then invoke "bootsec /nt60 all /force". Then invoke "bcdboot c:\windows /f ALL". Then invoke "bootrec /fixmbr". Then invoke "bootrec /fixboot". The details in the video start at about the 2 minute mark and finish at about 6 minutes.

Windows 10 keeps the bcd folder in a separate partition, so you need to use diskpart to mount the partition to a drive letter and adjust the commands/steps identified in the snippet. How do you do this?
