furri Posted October 11, 2005 Share Posted October 11, 2005 Hi Guys, I want to build a dual boot system with each OS on a separate disk but with both disks on a single IDE channel. This is because my mobo only has 2 IDE channels and I want to leave one channel solely for the DVD burner. So I have installed XP and OSX on 2 separate HD's with each running great, but at present I'm physically disconnecting and reconnecting the IDE ribbon cable from one drive to the other to switch OS! I've read all I can find on chain0 and editing the boot.ini file but I'm not sure if this method suits my requirements (putting both HD's on a single IDE channel one as primary, the other as slave). Or if this is even possible at all. Can anyone advise? Any help is massively appreciated. Thanks Furri Link to comment https://www.insanelymac.com/forum/topic/3412-dual-booting-from-2-separate-hds-not-partitions/ Share on other sites More sharing options...

Big Kahuna Posted October 11, 2005 Share Posted October 11, 2005 go ahead and install XP on your Primary Drive. to set up multibooting using osx on your second drive, use this guide: http://wiki.osx86project.org/wiki/index.ph...bootloader_boot Link to comment https://www.insanelymac.com/forum/topic/3412-dual-booting-from-2-separate-hds-not-partitions/#findComment-21682 Share on other sites More sharing options...
Druid Posted October 11, 2005 Share Posted October 11, 2005 Why not just use cable select..I imagine your mobo supports it and switch boot order of the hard drives in the bios when you wanna switch..that's the setup I have..works wonders, just use one ide cable with master and slave connections on it, and set the jumpers to cable select Link to comment https://www.insanelymac.com/forum/topic/3412-dual-booting-from-2-separate-hds-not-partitions/#findComment-21707 Share on other sites More sharing options...
Big Kahuna Posted October 11, 2005 Share Posted October 11, 2005 yeah, but why should I have to jump in the bios every time I boot? the chain0 method is easy, copy one file, edit one line in boot.ini. done! if you decide to remove OSx, just remove the line in the boot.ini and the file. done.

Druid Posted October 11, 2005 Share Posted October 11, 2005 Ahh, I guess if you still rely on windows and switch back and forth commonly that would be better. also it sounds like he needs a dual ide cable..sounds like she/he only has a single.

I installed OSX using the generic DVD. Do you know if chain0 is on this DVD or do I need to download the Darwin image?

furri Posted October 12, 2005 Author Share Posted October 12, 2005 I've unzipped the chain0 file to the root of my C drive. Due to my OSX installation being on another drive the chain0 file isn't working and I get the chain booting error. I think I need to add a line to the boot.ini something like this: multi(0)disk(0)rdisk(1)partition(1)\?????????="Mac OSx86" /fastdetect ???????? = I'm not sure what the root system folder of OSX is. Am I getting any closer? BTW, I'm using 1 IDE cable with 2 connectors; XP is on the master HD and OSX is on the slave.

furri Posted October 12, 2005 Author Share Posted October 12, 2005 After messing around with this for several hours I've found that (without going down the cable select route) the only way of booting OSX on a slave HD is using the Darwin bootloader on the DVD. To boot OSX on the slave HD, the DVD must be in the drive and when prompted I press F8 then rd=disk1s1. As far as I know, its the only way.

Actually any Boot Manager you install into MBR of 1st disk can handle this easily. I boot OSX off slave of 2nd IDE port using Boot Magic. Lots of People use Grub Google "Boot Manager" for lots of choices.

Grub was the best choice for me: - I can boot OSX, XP & Suse Linux (I will install FreeBSD later) - It's free Link to comment https://www.insanelymac.com/forum/topic/3412-dual-booting-from-2-separate-hds-not-partitions/#findComment-21960 Share on other sites More sharing options...
