My son has an HP Paviliion 915 computor, when starting screen goes directly to password login, he has forgotten the password, it's his password not admins. as it gives him a hint we know the hint just not the answer. None of the F-keys during the black screen stage work. It just goes to login. We cannot get into safe-mode, or bios. We ordered the recovery disc set from HP, however we cannot get in to change the boot order. When we put the disc in and started up nothing just went to login. At this point we're willing to do a complete recovery even if it means loosing hundreds of purchased songs from iTunes. But would prefer to try to save them if possible. Can anyone help me?
