My experience with BOINC OS

So, I decided to install and test out BOINC OS, which is made by @delta1512. Unfortunately I could not make it work with my spare hardware which is:

• Intel Core 2 Duo E4300
• AMD Radeon HD7770
• ASUS P5B Deluxe
• 2.5GB of Patriot DDR 2 RAM
• Corsair VS550 PSU
• Seagate Barracuda 80GB ATA HDD.

I tried to run it using two different (8 GB and 16GB) memory sticks and using external DVD Drive with image written to an DVD-RW disc.

PC just didn't boot (it has BIOS not UEFI, it is old MOBO); It was automatically passing to second boot option, no matter how I or what image of BOINC OS I have been using.

Any help, ideas how to boot this on my PC?
