bootcamp assistant refuses to assist
This on my trusty old early 2007 20" iMac (2.16Ghz Core2Duo)-3GBRAM-250GB HD-RadeonX1600(256MB)
Previously, this machine ran the latest version of OSX Lion.
I did a full system restore on this machine to pass it on to my son. So restore from original system discs (Tiger), download and install all updates, upgrade to Leopard from DVD, download and install all updates, upgrade to SnowLeopard, download and install all updates. Finished.
I do not want to upgrade back to Lion yet, because it will not allow me to install WinXP, and Win7 is not supported on this hardware (technically a late 2006, last of the white ones).
I open Bootcamp Assistant, but when I click continue on the first window, I get this:
The startup disk cannot be partitioned or restored to a single partition.
The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows.
So I run Disk Utilities, 'Verify Disk', everything checks out, of course the disk is formatted as Mac OS Extended (Journaled). Yet Bootcamp won't let me continue.
What do I do?
Mac Pro, Mac OS X (10.6.8), '09/2.66GHz quad/12GB RAM
