Vista Beta 2 is a 64-bit operating system. You cannot install it from inside
XP x86, a 32-bit operating system.
Before you go any further, please keep in mind that Vista Beta is not stable
and should not be installed on a computer that you intend to actually use.
For somebody who is as unfamiliar with basic things like .iso files, you may
be overwhelmed by the upcoming situations if you intend to actually use this
beta as your primary source computer. Beta releases primarily are for people
to test the software and find the problems, because it does have many
problems. Some people find this fun and challenging. You may or may not.
Because this is a 64-bit operating system, it is likely that most of your
peripherals (mouse, modem, ethernet, printer, etc...) may not work correctly.
Also, many older software programs that were written with 16-bit
installation sequences will not work. Ever.
If you still want to install this operating system, I stongly urge you to
purchase a program from Norton (Symantec) called PartitionMagic 8.0. This
will help you to create a partition (virtual) hard-drive. Make this new one
at least 25 GB. If you do not install to a new partition you will lose your
current operating system and any files too. And you will never get them
back. Ever.
Then pop in the DVD you just made and turn the computer off, and then on
again. The installer will ask you where it should install and you then tell
it to install on your new partition.
Search around on the forum and read a few horror stories, and also some more
indepth instructions for creating a partition and installing a new operating
system to a new partition. This is commonly called a dual-boot system
(although there are some pirates out there with duel-boot systems... sorry,
ninja joke), because when you try to actual use Vista and nothing works and
then your screen locks up, you can still boot into your other OS and
everything will be good again.
SERENITY NOW!
