Hello, I got a free optiplex, and formatted the hard drive to try and install Gentoo on it. Every time i try and start the computer and boot to any disk, whether a BIOS or Gentoo, it says press F1 to restart or F2 to enter setup...and I try one of those keys but nothing happens. Ive checked the connections, contacted Dell (hahaha)...they said that the hard drive might be broken but it was fine before i formatted it. Any ideas?
