According to the documentation (which I printed out) says possible floppy driveor hard drive failure. Says to reseat all power and data cables. Screen also says to press F1 to continue or F2 for start up. I can't do this because my usb keyboard still doesn't work.
Your 1st error indicated a HDD error and to run chkdsk /r. The reboot indicates another error re HDD (lights 2&3). You may have to replace the Data Cable, or the HDD itself.
