Issues dual-booting MBP3,1

[Pyrocide]

Hello All,

 

I recently came into possession of a MBP with a broken hinge/bezel and decided to throw Mountain Lion and Ubuntu on it.

 

Mountain Lion install was the easy part, took a bit longer than expected, never the less done and over with.

 

I installed rEFIt

Partitioned my 500GB drive (100GB for Ubuntu)

Used unetbootin on 4 different USB drives (Sandisk 4GB, PNY 4GB, noname 1GB, Corsair 8GB) as I read that Mac hardware doesn't like USB drives often. Got 4 bootable USB drives (working on a separate Win laptop)

Burned the x64 ISO to a DVD as well just for safe measure.

 

Restart into the rEFIt menu, run partition tool, and choose Boot Legacy OS from HD/CD/DVD/"ubuntu usb" etc whatever the media is and every time this is done, I get a "missing OS" message and a blinking cursor.

 

I even tried booting the boot img and get to the grub screen choose any one of the 2 install options as well as the live option and just sit staring at a blank screen. Let it sit for hours on one drive and still nothing.

 

Tried holding C to boot off CD instead of rEFIt, cleared NVRAM, reset SMC, MacOSx works flawlessly. Linux installer just will not load.

 

What am I doing wrong here? I cant possibly have THAT bad of luck with USB drives. Thanks for the help.

PS. If anyone has or knows where I can find the hinge for the MBP I would be most appreciative as I don't feel like spending 800$ on the entire display from Apple just for a hinge/bezel

You can't boot from a USB drive in legacy mode. Legacy mode just gives a simple BIOS that will support the optical drive and whatever hard drive EFI set as your C: drive for it.
