Perhaps dual boot could be a solution to Jim's original question. It
would allow
him to compare the speed and features on both OSs and figure out for his
system and tasks which OS is the upgrade.
Do you have some links on setting up dual boot on systems that are
starting
out as Vista only and WXp only?
No, but the process is the same. Install the older OS first, in this case
XP, then the newer one, Vista, into a separate partition or drive. The
Vista boot loader will setup the dual boot.
There are some considerations in doing a dual boot with Vista and XP.
Firstly if you have an upgrade version of Vista, the Vista license does not
allow for Vista and the qualifying OS that is the basis for using an upgrade
version to be installed at the same time. So if XP is the qualifying OS,
and a Vista upgrade is used, you cannot dual boot them. You must use a full
version of Vista, or have two XP licenses, one to qualify for the Vista
upgrade and a second one for the XP that is installed in the dual boot.
On the technical side, whenever booting into XP, all system restore points,
volume shadow copies, and all but the most recent backup created in Vista
will be deleted. Booting into Vista does not impact XP restore points. The
way to resolve this is to either encrypt the Vista partitions using
Bitlocker (available on Enterprise and Ultimate versions), or to use a 3rd
party boot manager such as BootIT NG to hide the Vista partitions from XP.
