How to fix the non-bootable Windows issue caused by Crowdstrike?
Windows 10 / Windows 11:
On the Windows recovery screen, please click “See advanced repair options”
On the Troubleshoot window, please click “Advanced options”
On the Advanced options menu, click on “Command Prompt”
Now the system will prompt you to unlock the drive with the Bitlocker recovery key:
Note the unique “Recovery Key ID,” and the unique “Drive Label”
Important: Please note the first 2 letters of the Drive Label at the bottom either FS or AP
Obtain the Bitlocker recovery key from one of these websites:
If the Drive Label starts with FS************, use https://mbam3.lehigh.edu/selfservice. (go.lehigh.edu/bitlockers). (Need first 8 characters of Recovery Key ID for the drive)
If the Drive Label starts with AP************, use
If you have any issues getting the recovery key, please put a ticket at http://lehigh.edu/help
After entering the key, a command prompt window will show up:
Type this command:
wmic logicaldisk list brief
Then take a note for the DeviceID that had the “Windows” VolumeName. In my case was C:
Delete the offending file. Type this command exactly using your DeviceID letter (note the filename with asterisk):
del /p C:\windows\system32\drivers\CrowdStrike\C-00000291*.sys
Then you will get a confirmation message that says are you sure you want to delete that file?
Please press Y but make sure that you are deleting the right file.
Finally, restart your computer.
