I have a samsung 30034c 300e5c 300e7c 64 bits with a BIOS: Phoenix SC-T v2.2.

Recently i install Ubuntu Studio 16.04 on an external hard drive, i was able to open the BIOS with f2 and every time i want to use ubuntu i hit the f10 button without a problem, everything is smooth and nice, and i'm thrill with this system, but now i want to install it on my hard drive and replace windows 7 that is currently on the computer hard drive. 

The problem begins when this laptop was purchase, windows 8 was its operating system and then it was replaced with win 7 (not without a fight), and i've reading about replacing win 7 with ubuntu and i found out that some Samsung computers have problems with ubuntu, some odds things happend with the BIOS and the UEFI, making the computer useless.
