The rescue CD seems to be broken. I can boot off the thumbdrive it created, but it presents a Unix login prompt after asking what language I want. Since there is no documentation with this software, there also isn't an account to use. This is what I did:
- Downloaded the ISO and Stickifier from http://download.bitdefender.com/rescue_cd/latest/
- Ran Stickifier, copying the ISO to my thumbdrive (I:)
- Rebooted my PC, selecting I: as the boot device
- When the Bitdefender wallpaper and menu appeared, I selected "run BitDefender 2015 Rescue CD in English"
- The system flashed between text and wallpaper several times, then asked for a username and password
