just tested the bootpack with 10.10.3, no issue. 

Make sure to use the correct patched Kernel if you're installing 10.10.3. Can't use patched kernel from 10.10.2 or older.

If you have an external video card, you'll need to remove that. In the BIOS, set all to default, apply and then set SATA Operations to AHCI.

Also boot on the USB 2.0 port, not USB 3.0, you'll get a better chance of success.
