Windows on a partition on the HDD. Possibly to format?

[Rixxz2]

Well, long story short, my aunt asked me to format her PC. However, she doesn't have the Windows XP disc. HP decided to be fucknuggets and laid it on a partition on the HDD.

Now, how the fuck do I reinstall Windows XP? She tells me she's had help formatting it before.

The PC in question is an old ass HP. It's probably around 6 years old.

(Also, just to clear some things up, I'm not at her place yet, but I'm currently on the bus that'll take me there).

Meh. Google'd it. You're supposed to press F10 during boot.

Yupp, done this to my PC myself ( i got HP) It's very easy to format, really.
