A few separate questions here so to take them in order:

1) Cracked screen: Have you looked into replacing this ? Would be the
better solution all round and the screens themselves aren't expensive.

2) Getting OS to use external by default: You should be able to start
the installation from external USB ( either flash drive or CD drive )
by having it plugged in then tapping the [F12] key during boot. The
initial screens should appear on both internal and external screens
but once the WinXP installer gets to the configuring hardware bit you
may need to use the manual switch on the Dell to see what's going on.
One of the function keys should do this, usually holding down the
[Fn] key whilst pressing [F6] or [F7].

Alternatively you could use Virtual Box and install WinXP in that so
you'll not lose your Mint installation :-)

3) Running .exe files: Yes you can run these using Wine, or Play on
Linux, but the results will vary according to what you are trying to
run. Some programs will work, some will work but not 100%, some will
refuse to work no matter what you do. Question is, what program(s) are
you wanting to run ?

4) VMWare is a bit heavy IMHO and Virtual Box is lighter. How well it
works you can only determine by giving it a try and you've nothing to
lose apart from a bit of time so why not load up Virtual Box and see
how your WinXP runs in that ? You don't need to give it a load of
memory during the setup, 128Mb or 256Mb will be fine - the bulk of the
memory load is still with the host OS when running virtual OS's :-)

Hope this is useful but I'd still recommend you look into replacing
that screen - not as daunting as it may seem, just need to know which
end of a screwdriver is which and take it carefully

This machine is for a teen who needs just one program that only works
under Windows.
It was bought used, very cheap so any extra investment is trying to be
avoided but an option down the road. There are several other internet
devices in the home so this one is not a priority.

f1 has the monitor icon and works to active external monitor but only
after BIOS boots. The first clear graphic I get is the cursor arrow in
blank screen and then the boot into Linux. FN & f1 screen says
"missing operating system", but its there on reboot.

I think this may be my solution. Thanks. I was going to run the XP
disk from cd at start up but again I don't get to see the screen when
the disk prompts to begin install. I tested it on another laptop with
external monitor plugged in and saw the info displayed from the second
it was powered on so I know its possible just maybe not on this
certain machine.

?winnt32.exe? The executable to manually start the windows clean
install from the desktop.

Good news!

I'll take apart desktops all day long. Laptops still make me a bit nervous....

If you got it cheap then perhaps it's worth considering replacing the
screen at some point. I too was a little nervous when first taking a
laptop apart but now they are just different to a desktop and pose no
real problem :-)

You cannot start a Windows install through Wine - it just won't work
so no point going any further with that one. Give Virtual Box a try
and I think you'll find it works well but it does depend on what
program you intend to run. Most work fine but anything that needs
direct access to hardware ( notably games ) will struggle and may even
not work at all so what program is it ?

The program is ooVoo. It didn't work with WINE on this machine. 1
person said they got it to work with Virtual Box. There are other
similar apps out there (Hypeater and Skype) but this is the one we
need to work...

ooVoo should work fine but you do realize that with Virtual Box you
will still need a valid Windows COA and installation media ? Also the
Windows installation is just as vulnerable to viruses and malware as a
native Windows system would be so you'll need the same protection. The
advantage of Wine ( if the program works in it ) is that you get Linux
security so even programs that could get attacked in Windows are safe
to use.

BTW - if a Windows installation in Virtual Box does get hit by viruses
or malware it won't spread to Ubuntu, and there's a neat 'snapshot'
feature which you can use that can fully undo everything - like System
Restore on Speed Just need to take a snapshot once Windows is
configured but bear in mind this also includes data so going back also
means data loaded since then is toast.
