Hello guys

I have a problem with the BIOS. I have a Dell Studio 1558th BIOS version is A12.
So the problem is that when I set Boot from second HDD (I have 2 HDD in a laptop, a DVD drive instead, and it is SSD). So when I switch the BIOS boot from first HDD to SSD and save a species so it works great first start, but the types of boots start again from the first HDD.

some idea ? 

Thanks for your understand and answers.
