Plucka Posted July 31, 2007 Share Posted July 31, 2007 Hi all, I have asked this before, but got stuck when it came to details? Could someone please post some detailed info on how you would go about dualbooting 2 osx's on a single hard drive with 2 partitions. I have two 40gig,on the first partition is 10.4.8 Biker ich7 and on the second one I have a lot of Apps backed up that I have downloaded and wanted to keep when I have to reinstall I can apply them without searching. On the second partition I would like to try Uphuck 10.4.9 with patch 10.4.10! Is there a better way, or can a second Osx live happily with all the apps, please help would really like to have an extra version installed for experimenting. Please reply, and thanks a lot, Cheers, Plucka Link to comment https://www.insanelymac.com/forum/topic/58580-2-versions-of-osx-on-one-partitioned-hd-please-help/ Share on other sites More sharing options...
BJMoose Posted July 31, 2007 Share Posted July 31, 2007 My guess is that when you install uphuck on that second partition you will lose your software so be sure to back it up on DVDs first. Hard drives are pretty inexpensive these days. Is there a way you could either install a second internal drive or at least an external usb drive to back up any data?

Hello there BJ Moose, thanks for your reply, as a matter of fact I do have a second HD installed but thats for Vista, I have a manual dualboot system, in the Bios I have to disable the Vista drive and enable the Osx drive, plus disable APCI. But I dont mind this because I know I always have one system that is bootable if something goes wrong. I could put the software onto the first partition with 10.4.8 on it, could you help with more details about the actual dualboot then? My system: Processor pentium 4 2.4ghz sse2 no sse3 Video Nvidia gforce 4200ti 256mb agp (no core image or QE, any help here much apprciated?) Sound realtek AC97 working with msi kext (sometimes choppy?) Motherboard msi ms-6547 Memory is 1gb ram Hard drives are both ATA Anyway thanks very much for replying and I eagerly await you answer, Cheers, Plucka Link to comment https://www.insanelymac.com/forum/topic/58580-2-versions-of-osx-on-one-partitioned-hd-please-help/#findComment-418294 Share on other sites More sharing options...
roxen Posted July 31, 2007 Share Posted July 31, 2007 Just install OSX on the second partition and at startup press F8 to manualy choose the boot partition or use fdisk in the Terminal to set de active boot partition. sudo fdisk -e /dev/rdisk0 (or rdisk1 ...) then use print (p) to see partitions from that disk and Flag (f) the given table entry as bootable. So if you want the second partition active type 'f 2' and then quit and save. Use 'man fdisk' to see the manual.

Thankyou for the info, I forgot to mention one detail, and I dont know if its important or not but the second partition is Mac Osx extended, does this influence your advice in any way? So what your saying is I can install a second Osx on the second partition and if I dont do anything at boot it boots into the existing 10.4.8? Thakyou for your reply, cheers Plucka Link to comment https://www.insanelymac.com/forum/topic/58580-2-versions-of-osx-on-one-partitioned-hd-please-help/#findComment-418313 Share on other sites More sharing options...
roxen Posted July 31, 2007 Share Posted July 31, 2007 I got two Partitions on one HD bootable, both Mac OS Extended (Journaled). To change, this is all it takes: sudo fdisk -e /dev/rdisk0 fdisk: 1> f 2 Partition 2 marked active. fdisk:*1> q Writing current MBR to disk. A reboot will be needed for changes to take effect. OK?

My second partion is not journaled just mac osx extended. Also will this affect my 10.4.8 install in any way? Sorry if you find these questions annoying, from several bad experiences an umpteen reinstals, you can appreciate how cautious I am. Thanks once again Cheers, Plucka Link to comment https://www.insanelymac.com/forum/topic/58580-2-versions-of-osx-on-one-partitioned-hd-please-help/#findComment-418331 Share on other sites More sharing options...
