Hello, i have and old Dell XPS 420 (Q9300, 5gb RAM) and today i wanted to install a fresh windows 7 on the new SSD. The problem is that i cannot install windows from a USB device and a lot of people have told me that i need to first disable boot secure to be able to do that. I've looked in the bios (bios version A07) and there is no option regarding the boot secure, so my question is: where do i find that option?

Any replies would be so much welcomed.

Thank you,

Andrew
