Btw I did find a solution to my prob. I'll post it here in case other asus users have the same problem. I finally got administrative access to the bios.

Here's how to easily reset your BIOS or UEFI password on Asus laptops (actually it will remove your BIOS UEFI password, wipe it out) :
This only works if you can boot into windows (or other OS) ! It will reset you BIOS or UEFI password if you have forgotten it.
- Boot into windows and change the date to 2002/01/02,
- Reboot while while hitting F2 to get into the BIOS / UEFI, when the enter password window appears hit "Alt + r", a "Enter rescue password" window will appear, with 2002/01/02 date showing (if not the code won't work), enter the following rescue password : ALAA4ABA
- Done ! You're in the BIOS / UEFI
- Change back the date and other settings to their correct values in the BIOS / UEFI, save settings, and you're good.
On the internet, you can even find whole lists of date/password couples to enter in the "Enter recovery password" window, i used the one above which worked perfectly.. "
Cheers
