How to dual boot Vista and XP (with Vista installed first) -- the step-by-step guide | APC Magazine

One problem I have with Vista is that certain XP-happy programs (eg Camtasia Studio) either don't work (in the case of version 3) or have limited functionality (in the case of CS v4, since disabling of hardware acceleration, for smooth capturing of on-screen video, is not possible.)
Note: According to Microsoft, it is possible to disable hardware acceleration under Vista by editing the registry. But the advice on how to do this is seriously flawed. For intance, even the reference to Microsoft in the edited registry entry is mis-spelled:

Disable Hardware Acceleration Option
Registry key Value type
HKEY_CURRENT_USER\SOFTWARE\Microsof\Avalon.Graphics\DisableHWAcceleration
DWORD
The disable hardware acceleration option enables you to turn off hardware acceleration for debugging and test purposes. When you see rendering artifacts in a application, try turning off hardware acceleration. If the artifact disappears, the problem might be with your video driver.

A solution could be to set up dual-boot, with XP available for when I want to use hardware acceleration (or indeed any other program which has problems with Vista).

You'll also need to download EasyBCD from http://neosmart.net/downloads/software/EasyBCD/EasyBCD%201.6.exe

I'd be interested to hear from anyone who has tried this.
