Acer Aspire M5-583p :: Hard Drive Password / Can't Get Into BIOS

i was wanting to boot from a usb stick to try out ubuntu. and acer rep told me that in order to do that, i needed to set a password in the bios system. so i did so, and turned off security to set the password. when i boot now, i get that little blue screen to put in my password, and i know what is is, but when trying to turn that off and using f2 to enter the bios normally it won't let me. it will ask me in a different format for the password.

My password that i put in is blue. and it takes me to the default screen where i can put in another password to get into windows. acer told me i needed to send in the computer and pay 100 dollars which isn't gonna happen anytime soon. i really need to get into the bios system to change the order up the boot sequence so i can try out ubunu. or any other program i want. i just tried to update the bios driver, and it still asks me for a "sato security password" just to clear the air. it has some number and letters associated with the pop up.
