UEFI bios settings

I am having a nightmare with this Laptop, I have only had it a week and so far I have been unable to use it. I currently have an open thread about another issue but now a new issue has come up. 

I was asked to update the BIOS as instructed to A01 which I did, now when I go into the bios to alter settings every single option is greyed out, I literally cant change anything like I could before like boot settings, AHCI mode, USB settings etc , the only live options are creating system passwords. 

What is going on, Im really thinking about sending this thing back. 

Its a new 2014 Inpiron service number <ADMIN NOTE: Service tag removed per privacy policy>

Please Dell can you sort this out for me
