I've been running Bootcamp Beta 1.2 with Windows XP and OS X Tiger for quite a while and am very satisfied with the whole mix. Now I want to upgrade OS X to Leopard, but I have to complicate matters by expanding the amount of space dedicated to OS X. Apple's Leopard/Bootcamp page (http://www.apple.com/macosx/features/bootcamp.html) mentions how easy it will be to install the new drivers, but no mention is made of shrinking the Windows partition. Is it possible to resize the Windows position smaller, making more room for Leopard?

I recommend Gparted. It will resize (shrink in this case) the windows partition, and Disk Utility on the mac will enlarge the mac partition. If you don't have Disk Utility in Tiger, it's in the Leopard installer also.

Thanks. I used GPartEd for a multi-boot Windows workstation, so I probably still have the CD around.

Well, THAT was less than satisfacory!!! I downloaded the latest GPartED just to make sure I had the current version, and shrunk the Windows partition, believing that I should be able to reboot Windows afterward. I couldn't. "No system disk found", it said. No huge deal, since this is a non-mission-critical machine (read: no critical data stored hereon). So I dug out all the CDs I needed to reinstall Windows, and boom! The installer doesn't see the partitions at all, only one 80GB disk. That won't work.

So, if anyone knows how to solve this problem, I'd love to hear from you. And, if someone is reading this thread thinking about following along, you are warned. :)

At this point, I recommend repartitioning the disk in Disk Utility to 1 partition, and install leopard over tiger, and then use bootcamp in leopard to reinstall Windows XP.

I'll probably have to do that. It's very tantalizing, though, since I can still boot into Tiger and see all the Windows files in the "Untitled" drive.

In that case it's just a boot error. Try looking up fixing the MBR or something. If there is nothing that you need in there, a fresh install is always better anyways. At least you can get any files that you need.

And the answer is ...

rEFIt. rEFIt.dmg (refit.sourceforge.net) is a cool utility that is installed on OS X. Instead of holding down the Option key during the boot cycle, you get a nice little menu that allows you to pick the OS to boot. Also on the menu is a disk repair utility that is smart enough to recover a broken MBR. I ran that, rebooted, got a black screen, rebooted again, and got ChkDisk! It ran fine, and I have Windows back. (Like my wife says, "But I thought you didn't LIKE Windows?" "I don't, but I have work there.") So all is well, and kudos the the rEFIt guys!
