Need help installing Tiger 4.6!

Question

I have a powerbook G4 that runs OSX 2.8 currently, I'm trying to upgrade to Tiger, but whenever I restart to begin the installation, it boots up to a plain blue screen. I have more that enough space and specs, any reason why it wont boot up? Thanks

Answer 1

First, you must have at least 256 MBs of installed RAM to run Tiger. Second, you need a retail Tiger installation DVD. If you have a disc with a gray label then you have an OEM version intended for use on the machine with which it came. The retail Tiger DVD has a black label with a large gray "X". You will also need 6-8 GBs of free space during installation. This is in addition to maintaining a minimum of 8-10 GBs of free space for normal operation of OS X.
Be sure you repair the hard drive and permissions before attempting to upgrade your current system. You should also update all your third-party software for Tiger compatibility. This includes applications, preference panes, startupitems, login items, contextual menu items, etc. If you cannot find upgrades then remove them before installing Tiger.
I highly recommend you not upgrade 10.2.x. Instead I suggest you install Tiger using the Archive and Install option. You can select the option to preserve users and network preferences.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
