Windows 7: OSX and Windows 7 Dual Boot

OSX and Windows 7 Dual Boot

Anybody want to share their experience installing and booting OSX and Windows 7 in a dual boot, single drive, setup? I'm experienced in partitioning, etc. My first try was not sucessful, but I didn't really give it a chance. I had OSX running, but I couldn't get the dual boot sorted out and I ruined my Windows installation a couple times...gave up.

Just looking to see if threre are any people out there that can steer me a little.

Not having a Mac myself, I can't offer you first hand experience, but lifehacker (an awesome resource) has this to offer.

Dual Boot: Install Windows 7 Beta on Your Mac with Boot Camp

Though maybe someone here who has a Mac and has successfully done this can offer more adequate advice.

I think he's talking the other way around: putting OS X on a PC. Correct me if I'm wrong

I have a triple boot at the moment: Vista, Win7 and OS X. I just used a bootloader from the DVD and it picked up all my other operating systems... that's about it actually

Hello pmcgarr

I have dual boot W7 and OSX 10.5.6.

All you need to do is first , install W7. Then, create a new partition for your osx within W7 , format it as fat32 or ntfs and set to to be "active".

Then run the osx installation and before you start the install, go to Utilities and "disk utility" , select the partition you created from W7 and format it as Journaled (don't delete it!).

Then, install as you would normally, selecting this partition as your installation target. (don't forget to customize your OSX installation with the necessary drivers for you system.)

After installation is complete, you will need to repair your W7 boot loader, cause you probably won't be able to boot W7.
Insert the W7 installation DVD, at the first installation screen select your language etc, and at the second screen select "repair computer".
This will bring the W7 boot loader back, so you can boot W7.

Now you won't be able to load osx!
So boot in Windows 7, and unhide your hidden 200MB partition:

1. In disk management, assign a drive letter for your 200MB hidden partition.

2.Download EasyBCD and add a new boot entry, select MacOS, Generic X86, Add, Save. That's it.

You can now have dual boot with W7 and OSX

I'm having just a bit of an issue, I format the partition that I want to used for OSX to fat32 and make it active, When I get into the OSX installation, I select the partition and format it for Mac OS Extended (Journaled). But when I do that it seems to change the format of the other 2 partitions on the drive but doesn't change anything on the partition selected. I may be doing somethign wrong, but I just don't see it. Any advice would be apreciated.

You might be doing something wrong.

Are you sure you're not deleting the partition in osx installation?
Try to label the partition from within Win7 so you can recognize it later in OSX install. You should only alter that partition. Additionally, you might be changing the partitio type...you should leave it as it is (GUID, I think) or in any case, don't change anything under OSX format, just format as journaled.

If you're still having problems, please tell us which osx version are you installing
