By system, I meant what hardware are you running? I know you are trying to install Lion, but you give no indication of the hardware that you are running. See my signature and profile for an example of what you can provide.
Having said that, I'm not sure any of that will help. Verifying DMI Pool Data errors can be generated by improper BIOS settings, possible loose cables, or failed hardware. Since you had just completed your install I will assume that the computer was fully functional. Can you get into your BIOS during the boot process? If you can, then you should probably reload Optimized Defaults, then reboot. When rebooting, go back into your BIOS and reset all of your settings back to your Hackintosh settings (AHCI, HPET, etc). After that, reboot with your UniBeast drive and start the installation again, or boot into the installation that you finished (if it is still there).
