o0revenger0o Posted June 8, 2009 Share Posted June 8, 2009 Ok. I am a total noob when it comes to os x. Now i am running kalyway 10.5.5and i am too scared to update to 10.5.6 and then to 10.5.7. So what i wanna do is install another copy of os x on a separate partition so i can test it. This is because i don't want to risk loosing all my data and stuff. So guys, do u think this is possible or it will mess up the darwin boot-loader ?? Any suggestions or HELP would be greatly appreciated. PLEASE REPLY!

tk31 Posted June 10, 2009 Share Posted June 10, 2009 thats a VERY good idea.. ive got 2 OSX installs on mine, and no it wont.. it'll just show up like this: Darwin Boot loader. (0,1) Mac OSX #1 (0,2) Mac OSX #2 thats IF you hit F8. if you dont hit F8, it'll just boot into your latest install. you can also change which bootloader you see when u start up your computer. Insert your DVD, and hit F8 when it loads up. type in: -s and hit enter. When it's done loading, type in fdisk -e /dev/rdisk0 then type in: flag 1 or flag 2 (partition number u want to boot from) then type: quit This writes it to the MBR. then: reboot this basically changes which OSX installation boots automatically if u let it count down to 0. You might get a "cant find MBR" error or a "cant write to MBR" error. dont worry, the MBR is still there. As long as your cursor changes to "fdisk" or sometihng similar, your fine.
