I've read on here, that it's possible to install OSX on my 750JW. Something I've thought about since picking up this computer. Recently I've become in need of running Kali Linux on my computer as well. I can't seem to figure out how to how to allow me to boot from a different device other than Windows Boot Manager. I've google'd and searched through this forum, and done all the steps that I've read, but NOTHING brings up different options other than Windows Boot Manager as an option to boot from. Kind of frustrating. I was originally going to just Live CD Kali, but I'm attempting the USB boot now, see if that will work better. I would however like to install 3 OS's and have them be able to be booted differently, depending on what I'm doing. Is this possible, and if so, what do I need to do? I do have a few larger games, that I don't want to have to download from Steam/Origin again so is it possible to backup the install directory to an external HDD and copy it back over after installing the OS again? Thanks for the info in advance!
