Microsoft Vista on Apple Mac OS/X

After my Vista post (above) I had several emails about the base install of a Vista upgrade on OS/X. I have several spare WIndows XP licenses from defunct systems and assumed the upgrade would work with either an original XP CD or XP serial number before the Vista one. But no.

Here is my Vista install to OS/X with Parallels.

1) Get a modern licenced version of Parallels and install it on OS/X
2) Create a Vista partition in OS/X with at least 512Mb memory and 20 GB disk space
3) Boot the legitimate Vista DVD from the Parallels partition (when the Parallels session boots, it trys to start the DVD in any case)
4) Click "Install Now"
5) Do not enter a Product key when prompted - if you try to you will get an ACPI, BSOD or can't upgrade error.
6) You will see a list of Vista editions. Select the one you have bought.
7) Install Vista normally - though it will be a trial copy with no serial number, only valid for 30 days.
8) Once the install is complete after circa 30 minutes, restart the DVD-based Setup from within Windows Vista.
9) Perform an in-place upgrade.
10) Enter your Product Key when prompted
11) Let Vista go through the upgrade a second time.


This procedure is much faster than installing a copy of XP and then upgrading to Vista. In fact, the upgrade after the original install completed in about half an hour on my iMac.
