I came across a challenge that prevented my Windows 10 computer from booting. The issue arose when I uninstalled Paragon HFS+ special edition and installed Paragon HFS+ trial, after reboot my computer would not start and gave the following blue screen error:
By referencing a number of sources I was able to reach a solution that allowed my computer to boot. In my solution I used a USB hard drive dock to mount the existing drive as a USB device which allowed me to use another windows PC to decrypt the bitlocker drive.
You will need to delete some files and modify some registry keys. Proceed at your own risk. Make a backup of the registry hive and the files:
- %windir%/system32/drivers/hfs*.sys (search for hfs*.sys)
From the registry’s SYSTEM hive delete keys and folders pertaining to the keys listed below1.
I did this by searching through the hive for each key. A number of keys had text pertaining to other stuff, so be careful to edit the keys and delete things only pertaining to what is listed above.
Also, here’s a guide for opening a registry hive from a slave drive.
It may also be possible that just deleting the files or registry entries alone may be a fix, itself. If you get a chance try deleting just the .sys files and leave a comment whether that was successful.
where is that directory(ies) located?
The %windir% directory? In C:/Windows, usually. But if you type %windir% in run or explorer or anywhere it will take you right to %windir%
Thanks for this – I broke my WIndows 10 installation after installing Paragon HFS+ to access an external HDD. Couple of mistakes:
* The sys files are in %windir%/system32/drivers
* It’s csvol, not cs_vol
However, after following the guide I was still unable to boot into windows. I then discovered while screwing around in the recovery console that windows keeps a backup of the registry hives in %windir%/system32/config/RegBack. I copied the SYSTEM hive from RegBack (which was only 5 days old) over the one in config, and now I’m back in.
Thanks for the corrections! I wrote this from memory and made a few mistakes. Your comment will surely help others find a resolution.
Thank you so much James. You’ve saved for my life. I am eternally grateful.
