install to freeNAS results in blank screen with blinking cursor

[xsalarie]

hi everyone, i installed freeNAS on my old computer to use as a home server, the very first time i installed freeNAS it worked like a charm, installed and ran emediately.

i made some errors in the server so i was forced to reinstall, when i tried to reinstall the system it told me "primary GPT table is damaged, using secondary. please fix"

i fixed that by using another linux live bootable usb and sfdisk and gdisk (verifying, then writing the new table and that fixed the problem) so i tried to reinstall the system. but now wwhen it is installed i get the splash screen of my motherboard, followed by a black screen with a blinking cursor which moves down 2 colums....

anyone know how to fix this?

thanks in advance

adding this: new installment to a USB drive DOES function (meaning that it boots into freeNAS from the system installed on the USB drive 32GB 3.0)
