UPDATED Jan 3 2010 to support adding Windows 7 on the second partition of an already functional Snow Leopard install For posterity, the original version of this guide is attached as a text file below.

With this guide I’ve tried to list every single...

Whatever you want... in my case since I had the 160gb hd, I chose 75/75 aprox for each

The "Repair my computer" option shows up at the bottom of the second W7 install screen. The first screen asks you to select a language, the second has a big "Install Now" button, but to the lower left are two other options:
-What to know before you install Windows 7
-Repair my computer.

Hope I didnt kill OSX. Anyone have thought on how to fix? Thanks guys

I believe, although I am not certain, that the only way for W7 to boot on a GUID partition scheme (which OSX requires) is for it to be the first active partition. It doesn't have to be the ONLY active partition, but I think it has to be the first. I could be wrong here, but if I'm correct you'll never be able to dual boot with OSX installed on an earlier partition than W7. My family is in town for the holiday but I'll search around and report back if I learn more on that issue.

During your boot cycle, right after the Dell splash screen, do you still see the Chameleon bootloader screen, or is it now going directly to Windows or to a Windows bootloader?

It appears I am wrong here. W7 can be in any active partition of a GUID partition table, according to this guide over at InsanelyMac.

I think you need to reinstall Chameleon so that it reflects your current partition map. Launch into the SL USB. At the first screen, from the Utilities menu, select NetBookInstaller and run it only with the 'Install Chameleon' option selected.

Reboot and remove the USB stick. See if that fixes it. Good luck!

Unfortunately that did not work either... Just a quick question, my Chameleon version is only RC3, my bios is A05. It worked fine for installing OSX.... I assume it would not be causing the problems?

Ok BTW if I select Win7 as the active partition I get no Chameleon it just boots straight in... if I select OSX as active it launches a bootloader... but very quickly... then shows a grey screen like its trying to load OSX for a second, then black screen... then reboot

OK, you're pushing the limits of my OS understanding, but I think there is something fundamentally wrong with your partition map. I think you are running as an MBR, not a GUID table. Check this by doing the following:

-boot into your SL USB stick
-from utilities, run Disk Utility
-select your hard drive at the topmost level (should say 160 GB WDC or something like that
-on the lower right hand corner, what does it say for "Partition Map Scheme?"

Then you should have two disk icons in the second level of this drive on the left pane. Select each individually, and in the lower pane, how are they formatted? One should be NTFS, the other MacOS Extended (Journaled).

I don't know the differences between the different Chameleons. Did you make your SL USB stick with NetBookMaker 0.8.3 RC5? If so, you have the same Chameleon I used. If not, you can re-run NetBookMaker RC5 on a Mac and point it to the SL USB stick and it will update the version on the USB drive.

If you check the release notes for NetBookInstaller, it seems that there have been significant changes to the way Chameleon works since RC3. In addition, the kernel fix for the lack of Atom support in 10.6.2 was not introduced until RC4. So if you upgraded your SL install to 10.6.2, it won't be bootable.

No. XP cannot boot from a GUID partition, only MBR. I don't know how to do such an install, but I'm sure there are threads in this forum that would be able to help.

I've already have OSX installed and now I want to dual boot. Is it possible to create 2 partitions and then install W7 or do I have to format and start over?

I tried precisely this and was unable to get it to work. The W7 installer would not allow me to install on anything but the first partition of a newly formatted drive. So I erased it and started over, basing my work (and this guide) on Anguish's triple boot guide.

Yea i'm interested in this. Just bought a 10v with 16gb SSD. Don't know if that will be enough for both OS's.

My SL install is 10.18 GB, but that includes ~1.75 GB of software in addition to what SL installs. So I would say you could probably squeeze SL into ~8 GB, and others report <8 GB installs according to a quick Google search.

W7 took 10.98 GB, but that includes Office 2010 beta (840 MB) and AVG free (90 MB). So that seems to equal a default install size of about 10 GB.

I did not make any attempt to trim the installs by removing nonessential items.
