Thank you Precizion for the info
I have several installs I have done with my TechNet Windows 7 Ent x64 version. If yours is the Trial version I beleive it is only good for 90 days trial. I asume that you downloaded it as an .iso file.
That is best burned to DVD with ImgBurn (Freeware) at 4x speed & verify ON. So you may have had a bad burn that is preventing a complete install.
Does your MB Bios have the IDE mode for the HD's, even though it is a 1tb Sata HD ?
