how to uninstall fingerprint sw in safe mode?

[pogacsa]

hi,

i have run into a strange situation yesterday. I was using system-update as regular on my z61m, running XP pro. It has updated access connection and fingerprint reader software. After reboot i was not able to logging in, becasue i guess "myuser" was there, and that piece of lenovo trap was not able to write some files (no info what), just simply was able to hit next, and deadlock. Also tried to login as windows style, ctrl-alt-del and giving win pwd, went thru, but again stick in a modal window of fingerprint software. cannot access my computer.
so booted into safe mode and uninstalled some ibm/lenovo garbage, but unable to get rid of my fingerprint as windows installer layer is not runnig.
Currently the situation is even worst as computer is even not allowing me to get to login window, just booting and showing XP boot image.
So, currently no idea how to save my laptop. I really would not like to reinstal (as running since bought, and always found a way to fix it. But not today.)
thanks for any hints and comments
