Thanks a million, worked like a charm. Problem thus resolved.
For future reference, here's an quick outline of the steps that worked:
1. Download Hiren's BootCD 15.2 (or latest).
2. Mount the ISO to a CD or USB: I'd recommend RufusPortable (free, gave good results), and stay away from "ISO to USB", that comes with a bunch of malware and also gave me a faulty USB.
3. Boot from your CD/USB to reset your password: you can find at least one nice tutorial on youtube, probably many others exist. This step takes less than five minutes.
Total time for the whole process with downloads is under an hour.
Thanks again for your help everyone, and tmc8395 especially for a perfect answer.
