Installing Windows 8.1 on bootcamp in Yosemite in MacbookPro 2009 mid How do i install windows 8.1 or the latest in bootcamp in a Macbook pro 15 inch 2.53 ghz 2009 mid ? i tried installing parallels, but the system is damn slow due to graphics driven programmes running. My cd drive got some issues and wont accept any cds. So I have gotta rely upon the experts in macrumours to find a solution to boot OS from usb. So I followed http://forums.macrumors.com/showthread.php?t=1680652 I have followed this process and successfully completed 15 percent of the process, so far so good Now i reached the stage where its asking for partion ... hope no more surprises to the next stages. What I could see is that bootcamp let me create bootable version of only windows 7, 64 bit version !!! If everything goes well and if i see windows 7 installed, will i ever be able to upgrade to windows 8.1 in bootcamp ? Or is it restricted only upto Windows 7 for older MBPs on bootcamp ?
