Do you receive the following error message?
/bin/sh: can't access tty: job control turned off (initramfs)
Please try this approach:
1. Launch FixMeStick again, but this time when you see the screen with "FixMeStick - Virus Removal Device" and the 3 booting options listed in the top left corner, hit any key on your keyboard.
2. Using the down arrow on your keyboard, select the option that says "FixMeStick (Failsafe 1)" or "FixMeStick (Failsafe 2)"
3. Press enter
FixMeStick should now start and you should not receive the error message. Note, however, that you will have to perform the simple steps above each time you use FixMeStick.
