You know what I am having a similar problem with an Acer desktop that I bought a new hard drive for after my original took a nosedive. After the fist reboot during setup via usb flash drive, a black screen pops up saying "verifying DMI pool data" and it just stays on that screen. I tried switching the boot priority back from usb to the regular HDD, but it still halts at that screen. That screen always pops up during boot all the time but only for a second or two. Any help or suggestions would be greatly appreciated.
