    William, u are da man!!! This was a simple fix and it worked like a champ!
  • Mike Boreham Level 4 Level 4 (2,095 points)
    For the benefit of those for whom the fixes aren't working....I solved it by erasing and installing (booted from the DVD) and migrating all my apps, data and settings from a clone.

    Took more computer time, but no more work than the upgrade method and all seems good.

    Maybe a short explanation: I have a dual boot with a Windows XP and use rEFIt to boot. I never had any encryption software installed. I wanted to try the partition trick, but it does not work and tells me it cannot partition as resizing only works with journaled HFS+ - which is exactly what I am using. Anymore suggestions? I did also all of the repair permissions, verify, check and whatever.

    William and all others interested,
    I have the unibody MacBook Pro 17" with a 500gb drive (specs below). I attempted to try your "partition slider" tip that has worked for some users. However, in Disk Utility, when I go to the "Partition" tab the selection in the "Volume Scheme" dropdown list has "Current" selected, and I don't have the ability to slide adjust the partition size. Additionally, the "Options" button is disabled. I could probably erase the current partition and boot from DVD to a fresh install, but I was hoping for an easier solution.
    Much thanks to William all helping with this issue.

    Here is the requested output and some additional hardware configuration info. Please let me know if I can provide further information.

  • AGF09 Level 1 Level 1 (0 points)
    Hello, I'm running a MacBook Pro Core 2 Duo, no partition, 30 GB free, 10.5.8, no PGP but File Vault on.

    I cannot make the **** SL install. I've tried boot from the DVD, I've tried booting from an external drive, I've tried the original method of clicking "install" on the DVD and always the same "yellow triangle" saying: This Disk Cannot Be Used to Start Up Your Computer.

    What should I do?

    I'm on the desperate stage already...

    Thanks
  • bluecrabby Level 1 Level 1 (0 points)
    This really has gotten ridiculous. Apple should have had this resolved within a few hours of release. Surely this issue presented itself during the testing and beta process. For such a high-profile launch this really is not being handled swiftly.
  • lcs64 Level 1 Level 1 (0 points)
    Hi

    I had the same problem and no PGP installed.
    Unfortunately the suggestion of William doesn't work for me.
    I believe the problem was created by the upgrade of new big disk even if the upgrade was performed using Disk Utility.
    I spent a lot of time using iPartition resizing, moving, changing starting block making a comparison with another disk where there was no problem.
    Nothing ! At the end the only way was format again the disk, restore the system from backup and finally the cursed yellow triangle disappeared
    The Apple should provide a technical note where explain which kind of control the installer is doing on the partition !

    Regards, Luca
  • KenJKel Level 1 Level 1 (0 points)
    I Had the same Problem. Read this entire tread. I am running a 500gig HD with 10.5.8 and Linux Mint 7 on separate partitions. rEFIt for boot up choice. I tried adjusting partition size with DU, but no go. So I booted in linux and used gParted to repartition, and unpluged my external drive and...... and..... and!!!... Tada! it worked.

    So maybe try repartitioning with a nothing probram other than apples DU, and also unplug any extra drives.

    Good luck

  • William Maxwell Level 1 Level 1 (90 points)
    What I have found common to users that continue to get this message after they resize their partition in Disk Utility, is that they have used a third party utility to alter their partition to install Linux etc. Before altering the partition again to attempt to resolve this issue, I would highly recommend a full backup or your systems as a precaution. That might also be a good idea before using Disk Utility to. The Partition table is an essential part of the HD to access your data. Use caution when editing it.
  • Bookworm9405 Level 1 Level 1 (0 points)
    I use rEFIt with OS X, Windows, and Linux, and I was having this error upgrading from 10.5.7.

    I was able to solve it by booting into Linux and using parted to shrink the HFS+ partition holding OS X and thus putting about 1GB of free space between partitions (you only need 128MB, but I didn't have time to do the math for that). This allowed me to install because HFS+ requires at least 128MB of free space between partitions in order to be flagged as "bootable."

    Snow Leopard is working fine now; I haven't yet tested any other OS though.
  • ManuP Level 1 Level 1 (5 points)
    Hi William,

    Same problem on a MBP without PGP installed. Apple Support advises me to reformat and make a fresh install but I would prefer to avoid re-installing all softwares. (not yet tried your solution as I first want to be sure to have all necessary backups in case off).

  • William Maxwell Level 1 Level 1 (90 points)
    Once your precautionary backup is complete, please try the partition resize. I think you will be OK. Please let me know. Cheers.
  • Carl Muckenhirn Level 1 Level 1 (5 points)
    Have you had any progress on figuring what it is about Installer that makes it think a drive is not bootable, when "Startup Disk" is happy with the partition?

    It seems odd to me that the Installer would be this finicky about the partition table, when all it needs to do is operate within the existing partition. Someone obviously thought there was a reason to check something they believed to be immutable about Mac OS X installations, that turned out to be not true.

    In my case, I've now exhausted all possible alternatives short of blowing away the whole disk (which really *****, because I didn't want to have to take 5 hours getting a new O/S loaded...).

    1. Wiggle partition and save again in Disk Utility -- didn't work
    2. Take drive out an put in external case -- didn't work
    3. Try and install to MBP while in Target Mode -- didn't work

    c.
  • Evans Brasfield Level 2 Level 2 (185 points)
    I have had this problem before with user installed hard disks on other OS X installs (both clean and updates). In each case, the user had simply used Disk Utility to add the appropriate partition info onto the disk. While this worked fine for cloned copies of their systems the users had written to their new, larger disks, the Apple install DVD did not like it. In both cases, erasing the disk by writing zeros to it solved the problem. Adjusting the partition or rewriting it had no effect. The zeros had to be written. Then the installs went smooth as silk and data was restored from backups.

    Because of this, I now write zeros to all new disks I install.

    Hope this helps.
