Hello,
I had some free time and finally managed to crack DELL's restricted bios to accept USB boot, after a lot of frustrated attempts. It is like cracking a code. Why they make it so hard is beyond me, unless it is to stop the user fixing things himself?
I had to load Windows 8.1 and then upgrade to 10 to find my installation code. So after many hours I am up and running, I just have to decide whether to do a clean install now I have my code?
I would like to thank Bruno Schröder for his generous offer of help, I am very grateful.
Cheers
Bez
