|Some laptops have a recovery partition included on the drive. Check with hp support site, locate your model etc and see what the manual says regarding recovery options (including both on the drive itself and also a supplied disk set - if there is/was one).|
HP may well send your a replacement disk set - if you contact them and give them details of your laptop... Worth a try...
While the offer from "worldlibrary" is generous and so on.. it may not actually work... Disks sent with a given system are usually "fixed/tweaked" to work only with the kit they came with; or one that is "identical" in terms of bios, and a few items too (I suspect).
If you need help in terms of finding what's available at HP support, post the model number etc of your system here. Then folks here can/will likely have a look-see on your behalf, and then post the information you need here?
I suspect you will need more input anon so do post back with system details - model etc...
Do not post any personal details here though - including your email address, or anything that might allow others to spam you or worse... All you need to provide here is the HP model number of your system (which presumably is a laptop?).
There will likely be a sticker on the case (often on the base) showing the OEM details for the XP installation - aka the XP key entered during installation. Make a note of that and keep safe - do not post it here. That key as it's called "may" (will?) be needed for any re-installation routines you may run. So find it, and keep safe.
