Snow Leopard install problem... Help

[RKG]

Hi guys,

(first post haha)

Ummm Im having some major issues installing SL on my macbook white (luckily I backed it up). I inserted the install disc in leopard and the installer booted up etc. It seemed to be going fine until it rebooted.

When it rebooted it went into the OSX installer - i clicked the accept agreements etc again. Pressed install and my disc didn't show up. I looked in disc utility and it wasn't there either however when I went into system profile under Sata it showed the hdd.

I am really confused - 1. as to why it loaded the osx installer again and 2. why has my disc not displayed.

As it wasn't worse... Now my mac wont boot automatically off of the HD. I have to hold down the option key and select Mac HD else it wont boot. When it does boot it just goes back into leopard 10.5.8....

I dont understand... All I want to do i to be able to upgrade my mac to snow leopard. The internal HD is a 300GB WD HDD encase you wondered.

Any help would be appreciated.

Rebooting into 10.4/10.5 after install. You may also want to try verifying the hard drive while booted to 10.5.

As far as the drive not showing up as a valid install location, is the drive Mac OS Extended (Journaled)? Using the GUID partition scheme? Both of these can be determined by either selecting the volume or the partition in Disk Utility. Had you been using the drive or a partition of it to backup with Time Machine?

The system may not be automatically starting up from the internal drive if the Startup Disk preference was changed. Once you are able to boot with the option key held down, go to System Preferences->Startup Disk and make sure the hard drive is selected, then click restart, it should boot normally.

Yup its Journaled and GUID - I am also running Win XP via bootcamp...

Im backing up with TM via an external drive. Could it be because its a Western Digital drive - I know others experienced problems with this when upgrading to leopard and had to install via an external drive and then swap the discs.

That being said I never had a problem before - I don't really want to have to go through the whole process of swapping the drives around and then back again quite simply because I shouldn't have to.

Both discs also check out after a verify.
