Try removing all but 2gb RAM to try install.
Check for newer BIOS update. If none reset BIOS to defaults, set SATA controller in BIOS setup to AHCI to try install. Unplug all other HD's and peripherals.
If the HD is used at all then wipe it with Diskpart Clean Command
from DVD Command line using DISKPART At PC Startup
Next try unplugging the DVD drive. Write the latest installer ISO to flash stick using download tool given here.
Boot stick using one time BIOS Boot Menu key given on first boot screen, after setting HD first to boot in BIOS setup.
If this fails burn the latest ISO to DVD using Download tool to see if it is the problem. The error is almost always the installer so check DVD for scratches or dirt.
