HackerName Posted August 22, 2007 Share Posted August 22, 2007 As I said in the installation thread, I tried installing Leopard to the same BootCamp-made partition that I installed A466 on. This worked fine, but halfway through the Archive and Install I got an unknown error and I had to restart. It booted back into Tiger just fine (phew), but when I restarted back in the installer, no partitions appeared (eek!). I verified and repaired both partitions (only one needed minor repairs), as well as fixed permissions on the Tiger one (I know that won't make a difference, just thought I'd try everything). Still no dice. Disk utility on Tiger recognise the partitions just fine, but neither the Leopard 499 installer (on an external HD) nor the A466 Leopard recognise it. Curiously A466 can still boot up fine on the "unknown partition", but it won't recognise the Tiger one once booted up - neither in Finder nor Disk Utility (which doesn't show the boot-partition there either). Back in Tiger I tried undoing my partitioning with BootCamp Assistant. Uh-oh, gave me this message: "Your startup disk cannot be partitioned or restored to a single partition. Your startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows." So, something has definitely gone wrong with my GUID partitioning scheme, and there doesn't seem to be an easy way to restore it to normal. I even tried repartitioning it in Leopard disk utility (nailbiting experience), but it gave me the error that a "resource was busy". Any suggestions other than cloning the hard drive and reformatting?

HackerName Posted August 22, 2007 Author Share Posted August 22, 2007 So far I've tried: Merging the partitions with diskutil. Worked fine, but still isn't recognised by Leopard. Repartitioning with BootCamp. Works fine, but neither partition is recognised by Leopard. As a sidenote, BootCamp partitioning and collapsing only works with either a single JHFS+ partition, or one JHFS+ partition and one FAT32/Microsoft Basic Partition/NTFS partition, not with two JHFS+ partitions. The diskutil method for resizing on the fly via terminal works fine though. Still the problem remains: What's wrong with my partitioning scheme so that Leopard doesn't recognise it? My EFI partition starts at block 40, is this normal?

HackerName Posted August 24, 2007 Author Share Posted August 24, 2007 This forum is full of smart people. Anyone have any idea what might cause this? It's not an isolated incident either, as someone else posted the same problem in the installation thread.

AppleNick Posted August 24, 2007 Share Posted August 24, 2007 I had a similar problem. I just booted from the 9A466 installation disk, repaired permissions and my disk. Then my partitions were found again by 9A499 and I could easily upgrade.

HackerName Posted August 26, 2007 Author Share Posted August 26, 2007 I installed 9a527 to a different partition, repaired in 9a527 and was then able to install to it. Yay.
