This really is a known problem with dual booting XP and Vista. You are lucky
you have One restore point, I have never even had One! If you have Vista
Ultimate then use bitlocker encryption to solve the problem. If not then you
are going to loose the restore points. To be honest Microsoft know about it
and couldn't care. I bugged this issue all through the beta of Vista and the
simple reply was 'won't fix'.
An alternative is, rather than physically dual boot, use a virtual machine
instead. This means allows you to run both Vista and XP (assuming you have
enough memory) on the same partition at the same time. This is the method I
now use. Microsoft's own Virtual PC 2007 is available free (just Google
virtual pc 2007). One downside to VPC 2007 is that it has no USB support,
the last time I used it it also had no sound support for onboard sound. If
you need USB support, as I do because my USB printer doesn't work correctly
with Vista, you would need to look at VMWare WorkStation. Unfortunately, you
do have to pay for this one.
