This prohibitory sign is because of root device unavailability.

Try with different USB ports and make sure that USB options are correctly configured on BIOS.

You have to be more patient on installation of OS X. Apple not releasing OS for installing on custom build.

Make sure that VT-D is disabled on BIOS.

Post a picture of BIOS section where the USB related parameters present.
