Copy existing Windows Install to "boot camp".
If your Vista edition has Windows Backup and if you have a external USB drive of adequate size - you can run the Windows Backup and run complete PC backup to the USB drive. Then you will need to install Vista on your new Macbook Pro and again run Windows Backup to restore the image from the USB drive - I suspect you will need to re-activate Vista although that's just a phone call annoyance.
Please try to explain this a little better, OK? As it stands, it appears that you are instructing folks to
1) Do a complete PC backup
then,
2) Install Vista "cleanly" on your new machine
then
3) Replace that clean instance of Vista with the BACKUP you saved.
This makes absolutely NO SENSE to me.
First of all, Windows is NEVER "installed to BootCamp". Windows is installed on a TRUE Windows partition, which is CREATED by using BootCamp software, which then acts as a BOOT-LOADER for Vista, NOT your Apple machine.
Once Vista is installed using BootCamp software, and booted, NOT A SINGLE BIT Of Apple OS X code will be left in memory, so when running Windows on such a Windows partition on an Apple machine, the ONLY OS running is Windows. PERIOD. Boot Camps ONLY purpose is to create the Windows Partition, then allow your machine to be BOOTED into Windows.
For all intents and purposes, the machine will still be an Apple, but it will NOW be an "Apple" Windows-based PC. IN fact, NOTHING of OS X will be available to Vista when Windows is operating. Even the software which enables one to switch back to OS X is a strictly-WINDOWS application.
I would backup my USER files, but NOT my Windows OS itself, since you will be installing Vista freshly on your new machine anyway. The redundancy will make it more complicated, and possibly could BREAK your new install of Vista.
Also, EVERY clean install of Vista will have to be activated to be used beyone the 30-day shakedown period. There is NO WAY to get around this, short of using an illegal hack. Copying your "complete PC backup" back to your new installation of Vista MIGHT require you to activate it AGAIN, when it isn't necessary.
I advise you to follow OFFICIAL Apple instructions for installing Vista, rather than trying to do a messy hack using advice from people who really don't understand what they are advising you do do.
