Thanks to all who responded, the issue was I had more than one drive in the system.  Once I disconnected all the drives except the primary (C:\) the install went fine.  I had secure boot off and the CSM off but for some reason it just wouldn't work with the other drives hooked up, must have seen other partitions and that was causing the problem.

All is well now and running like a champ!  Again thanks to everyone who took the time to reply!!

What model?

 

Try F12 and change it back (I'm guessing it was on "Legacy" ?)

While that change might not let it boot, it shouldn't kill it.

Hi ‌,

Perhaps you mean secure boot on or off.  You cant change bios to UEFI  it is either UEFI or its not.

Legacy Compatability Support Mode CSM is still UEFI but secure boot is OFF which is required for windows 7 and for hardware and software that does not have a certificate in the BIOS from Microsoft.
