I have a mid 2010 Macbook Pro running Yosemite that I foolishly did a reset on while it was connected to an external monitor that was designated as default in settings And connected to a USB keyboard and mouse. Now I have the white screen of death on startup.
I have tried all keyboard combos to try to boot into safe mode, single user, reset PRAM, etc and none work. Yes, I know, I mucked up.
My question is; I have a working windows based desktop and is there any way for me to create a bootable image on an external drive (either USB or an external HD) so that I can at least get into some type of diagnostic on the MBP?
Thanks in advance.
