ok ok ok, relax! Bought the SL at Best Buy..But new problem. When I load the disks at start up it give me the language I wish to continue in, I choose english. Than it asks me to select the disk to install on, I choose he HD (the only option..I think). I agree to the terms and conditions and than it tries installing for about 2 or 3 seconds than gives me this message:
"The contents of this disk can't be changed. Mac OS X couldn't be installed on this disk."
Anyone else ever run into this problem? Any clues on how to fix this? Thanks guys for all the help.
This problem happens because the Snow Leopard installer detects a small discrepancy in the partition table of the drive, and assumes booting off the drive may not be successful. The fixes involve rewriting the table without formatting the drive, but if that does not work then formatting should definitely work (provided you have a backup).
Fixes:
1. Run drive checks.
The first thing to do is run Disk Utility or, even better, run a third-party utility program to check out the drive to ensure it is functioning correctly. Fixing any errors may require booting off a volume other than the boot volume (i.e., the Snow Leopard DVD or a Drive Genius DVD), and performing the fixes from there.
2. Repartition the drive.
This problem might happen even if the drive checks out with various disk utility software. The way around this is to have Disk Utility repartition the drive, which, luckily, can be done without having to format the drive. To do this, boot from the Snow Leopard DVD and select your language. Then launch "Disk Utility" from the "Utilities" menu and perform the following steps:
Select your boot device (the device above the boot volume name), and select the "Partition" tab.
Resize the partition by selecting the volume name in the rectangular volume representation and drag the bottom-right corner of it to change its size.
Click "Apply" to change the partition's size.
Revert the change by dragging the same resizing corner back to the bottom, and click "apply."
After this is done, quit out of Disk Utility and try installing Snow Leopard again. Since you are booted from the Snow Leopard DVD you should be able to continue immediately without having to reboot your system.
Workarounds:
1. Format and install.
If you have a full system backup via Time Machine or a drive clone, you can format your boot drive and do a clean install of OS X. To do this, first be sure your backups are complete and accessible, and then boot off the Snow Leopard DVD (click the "Utilities" button instead of "Continue" in the Leopard installer, or reboot and hold the "C" key to boot off the CD/DVD drive). When the installer loads, select your language and then launch "Disk Utility" from the "Utilities" menu and perform the following steps:
Select your boot device (the device above the boot volume name), and select the "Partition" tab.
Select "1 partition" from the drop-down menu, and then give the partition a name and format it as "Mac OS Extended (Journaled).
Click the "options" button and select "GUID" for the partition table.
Close this window and click "Apply" to repartition the table.
Close "Disk Utility" and continue with the Snow Leopard installation.
When the installation completes, migrate your data from your backup to the new system.
