thnak you so i did get a ssd drive 250 gig one.SO what i understand is when installing mac i need to point to the external to install the OSX.I read this can be done so when the laptop boots i will do the boot manager and select the external right,or are you saying i must swop the drive in my laptop to the ssd drive.either way i think it will still work.
I am gonna scrub the flash and start over and follow your link tutorial.NB...i still working on that probook to get signal to hdmi cause the new screen wont plug in and that darn cable is so short..lol
