Instructions: Autorun

Make a "writable filesystem" systemrescuecd usb according to this doc:

https://www.system-rescue.org/Installing-SystemRescue-on-a-USB-memory-stick/

Copy the autorun file from this repo to the /autorun/ folder in the systemrescuecd when mounted from your machine. If the usb is mounted to /mnt then the file should be at /mnt/autorun/autorun

Boot the usb key on a machine with the following BIOS/UEFI options if applicable

  • SATA Operation: AHCI
  • Secure Boot: Off

Note: you can set AHCI back to RAID On after running the script to boot Windows again if needed.

Make sure only 1 Windows HDD or SSD is installed on the machine.

If BitLocker is enabled, dislocker will be run to mount it, have your recovery key handy for this step.

Instructions: Manually

Just boot a plain old systemrescuecd iso and run the autorun as a shell script

bash ./autorun

Same bios settings as above apply.
