botaferro Posted February 14, 2009 Share Posted February 14, 2009 Hi everyone. Could somebody point me to a tutorial explaining how to install Windows after OSX? I'm not an expert in this kind of stuff, and when I first installed this computer I never managed to make it dual boot. Every time I tried to install Windows I lost OSX booting, so I quitted on Windows since I only needed OSX for my work. Now I also need Windows, but I'm afraid to try again and every Install option I can find talk about installing Windows first. Can I remove the OSX HD, install Windows on another disk and insert the OSX disk after? I have Kalyway 10.5.3 installed with the 10.5.4 apple update. Thanks In advance, and excuse me for my bad english. Link to comment https://www.insanelymac.com/forum/topic/153075-help-installing-windows-after-osx/ Share on other sites More sharing options...
whodidat Posted February 14, 2009 Share Posted February 14, 2009 the search button needs to be your best friend in this forum. btw, you just might not get any answers without at LEAST posting your specs...

botaferro Posted February 14, 2009 Author Share Posted February 14, 2009 the search button needs to be your best friend in this forum. btw, you just might not get any answers without at LEAST posting your specs... The search button was my friend but, like I said, I only found people talking about installing Windows first. But of course I don't put the question here and sit back in a corner. I'm still searching the forum and the web for an answer. But sometimes a little push is welcome. My computer specs are: Asus P5E Intel Core 2 Quad E6600 Asus NVidia GeForce 8600 GS 8GB RAM Kalyway 10.5.3 updated with Apple 10.5.4 update. Thanks.

Thanks In advance, and excuse me for my bad english. I haven't tried this with Windows 7, but I'm doing something similar with Windows Vista: * Install OS X on Drive 1 w/GUID partition and PC-EFI * Remove SATA connection to Drive 1 * Install Vista on Drive 2 * Re-connect Drive 1 * Use BIOS boot menu to select HD to boot (on my mobo you had f12 at POST screen) Works perfect, they don't intererfere with each other - VMWare Fusion recognizes the Vista "partition"/drive as "Boot Camp" and can boot it just fine.

Flea Collar Posted February 28, 2009 Share Posted February 28, 2009 I also have OSX 10.5.2 installed on one hard drive with 1 partition, can I add a 2nd partition with the Kalyway installer? Would like to dual boot with XP.

X-fact0r Posted July 16, 2009 Share Posted July 16, 2009 Dual Boot is old school, do something new school and install Windows in a virtual machine... www.virtualbox.org Indeed, but you cannot update your mobo bios or flash any firmwares through a virtual machine... I have 10.5.7 installed and will try to install Win7 on a different drive disconnecting the MacOS hd. My question is if Chameleon will be able to detect the new Win boot partition?

I have 10.5.7 installed and will try to install Win7 on a different drive disconnecting the MacOS hd. My question is if Chameleon will be able to detect the new Win boot partition? Yup. I even had an old laptop harddrive in an enclosure and when Chameleon loaded it had detected the stuff on the drive even though it was on USB. It is possible to install Windows after OSX. Infact my laptop I'm using right now was done that way. Can't remember exactly what I did but it was simple enough. Don't quote me on this but I think it went: 1) Installed OSX using boot132 (retail disk) 2) Installed Chameleon (system was now bootable) 3) Made a fat32 partition for Windows 4) Installed Windows (Vista) 5) Used the boot132 disk I had made and booted to OSX in single user mode (-s) 6) Set the OSX partition as active using: fdisk -e /dev/rdisk0 flag 1 quit reboot Its been so long I could have missed out a vital step but just to say it again you can do it. To do it with an unmodified retail disk the harddrive needs to be formatted as GPT which is not supported by XP. Vista and 7 support booting from EFI on GPT disks. iPoco Link to comment https://www.insanelymac.com/forum/topic/153075-help-installing-windows-after-osx/#findComment-1203335 Share on other sites More sharing options...

I had a spare free space partition which I have installed Windows 7 on... now only windows 7 boots and I can't get OSX to boot... how do I go about getting my OSX to boot again? Will the fdisk command work for me also?

Poco Posted July 21, 2009 Share Posted July 21, 2009 Yes. You can use the boot132 disk and boot with -s. There is a way to do this inside of the Disk Management in Windows. If you want you could also look into that. iPoco Link to comment https://www.insanelymac.com/forum/topic/153075-help-installing-windows-after-osx/#findComment-1205347 Share on other sites More sharing options...

X-fact0r Posted July 27, 2009 Share Posted July 27, 2009 Hi, made some progress this weekend. Grabbed a 2nd hard drive and in DiskUtil made 2 partitions in MBR. On the first one installed Win7 and after that fired Ubuntu. I chose the custom option on the HDD selection and made 3 partitions (1 for root, 1 swap and another /home). I chose to install GRUB on the / partition and not on the MBR. And that's it! Chameleon is able to detect the additional installations if you press a key when it boots Link to comment https://www.insanelymac.com/forum/topic/153075-help-installing-windows-after-osx/#findComment-1210109 Share on other sites More sharing options...
