Is it possible to have both XP and Vista existing at the same time?
I intend to install Vista on another hard disk and there will be a list to
select either XP or Vista to be loaded when bootup.
How can I achieve this?
Any idea would be appreciated.
That's been a standard feature since Win2000.
Dual-booting different windows version:
1) Always install the OSes in order from older to newer (important!!)
2) When you boot from the newer OS's CD or DVD, select another drive
or partition to install it on than where you installed the older.
Setup handles everything automatically (assuming you're dual-booting
with another windows version, linux won't work).
The next time you boot, you'll get an OS selection menu.
Win2000 could dual-boot with DOS, NT4 and Win9x, but I don't know if
Vista still supports all of those, or even if it supports anything
besides XP.
Never try to install two different OSes on the same partition. There
are ways to do it, but a lot of stuff will stop working in the oldest
one.
