Bryce, I have been building machines for quite some time. Probably longer than you have been thinking OO is bad for your health.
I tell you one thing, the registry is both your best friend and your worst enemy.
I am betting your WINXP CD is not a recovery, it is a "compiled" CDROM made by the manufacturer.
I tell you, copy the D:\\i386 directory from the CD to C:\\Windows\\Options\\.
So you then have C:\\Windows\\Options\\I386
Then in your registry, search for the setup location (currently D:\\i386) then change it to C:\\Windows\\Options\\I386. (I do not have a WinXP machine @ home anymore, so I cannot give you the exact Reg-entry)
From then on you'll never have to insert the CD-ROM. except on a catastrophic.
Thank you for playing.
