I'm going to echo booman on asking for the specific laptop model. Almost all newer laptops do not have BIOS anymore, but UEFI, which is a replacement of the old BIOS. The boot process is also different. When you install a distro such as Linux Mint, it will automatically detect if you have a BIOS or UEFI system, so you don't really need to worry much about it. However, there are a few things you need to be aware of, so if you post the laptop model then I can do a quick search to find out which it is.
Basically, if you have a UEFI system you need to disable a few things in the UEFI setup (which mostly looks identical to the old BIOS interface). A little tip, the most typical keys to enter the BIOS/UEFI setup screen is from my experience is:
F2 or the Delete key. With most newer laptop you need to start pressing it immediately after it boots. However, it could be that your laptop have another key, so trying out the difference F- keys might be necessary.
