bios access key asus eee pc

I just bought a Asus Eee Pc 1005PH and I want to install Ubuntu remix. I have downloaded the files to a USB stick and now I am supposed to configure the boot in bios in order to boot from the stick, but when I start up the machine there's no way to get into bios. It goes straight into windows with no break in the beginning, so there is no screen saying "press f2 to enter bios" or whatever. ANybody who knows how to fix this? Thank you
