Glad it worked for you... I was able to install and boot off the USB but still having trouble getting it to boot from the SSD. Any help you might be able to provide? Thanks!
EDIT: ended up being able to figure it out. For whatever reason it was forcing me to an MBR partition guide, so I grabbed the 10.10.3 MBR fix files and went that route. Booting into 10.10.3 beautifully. No audio yet, so gotta figure that one out still.
