Ah, got it.
I'm frankly not sure it would work. I suppose it's possible, w/ the right
software to access a linux share (using Samba?), but not sure that can be
extended to optical drives. I'm not so concerned about the Windows side,
but whether Linux could share it. Even if all this was possible, I'm not
sure the XP install wouldn't need the CD available after rebooting, when the
share (or any other) network resource might no longer be available.
Assuming that you currently have mininal connectivity between the machines,
you can use FTP, HTTP, or something similar to transfer the CD contents from
the Linux box to the laptop. So you'd have to have the ftp server, http
server, whatever, enabled on the Liunx side, then use IE or other FTP/HTTP
client and copy the files over. For a basic install, you only need the i386
folder contents anyway, but if you want the WHOLE CD, go for it. Using a
standard Internet protocol is just going to make things a whole lot easier.
Or if setting up a server is too much trouble, either email the contents to
yourself, or perhaps find a webhost that will act as an intermediary.
Granted, these last suggestions will take considerable space, more than
perhaps you have available, but it will work, if slowly. Or you might send
and retrieve the CD contents in "batches". I know, not ideal, but desperate
times call for desparate measures.
Once you have the files locally, it's a rather trivial matter to create a
new partition, move/copy the files there, and install from the HD (the CD is
not absolutely necessary for installation, the OS will install just fine
from the HD). But first determine if you want to do this, and how you will
transfer the files, then we can talk about getting the files on a new
partition.
