MacBookPro10,1 had problems booting, now some system images are pink and fuzzy
It sounds like your USB did not contain the clean bootable version.

I would suggest you start over and follow the procedure from Apple.

You can get a copy of 10.9.5 from here or from Apple Store.

Make sure the USB is single partition and minimal 8 Gig. (no other partitions on that disk)
