Good day,
I went that same route with an "attempted" Sony Laptop purchase a few months back...
The laptop came with Vista 64 and tons of trial-version / bloatware crap.
I found that 50% of programs (including Premiere 6.5 and Visual Basic 6.0) either did not work right and / or would not even install.
I attempted to use my trusty XP Pro disk and it blue-screened with a STOP 00000xB error meaning the 250 GB hard drive was not being recognized.
I tried this same route with my new desktop I put together myself, which as two 1.5 TB drives, and XP Pro installed fine (I had Vista 32 for that box but tried it, did not like it, so I went with XP Pro).
Much of the XP Pro install disks blue screened on the laptop. I was told pressing F6 (or F7) during the boot-from install CD and have the driver (for the HD) on a floppy / USB card or something.
The hard-drive was 250 GB Hitachi laptop, and no where could I find the driver. And Microsoft? Forget it.
Frustrated, I called it quits. Bringing the laptop back nailed me with a costly re-stock fee (but that story is in another ST thread).
I wout recommend for you trying to find the driver for the HD of the laptop, and putting it on a floppy or USB drive, and pressing F6 (or F7) to load it.
If you cannot install the damn OS, nothing will be possible with XP.
Sorry to say, XP is less and less available on laptops.
The next best thing is to simply use Vista, but you will need to upgrade / replace the programs (especially the older ones) that do not work - Costs lots and lots of $$$.
Windows 7 is showing a bit more promise...
