How can i install winxp in Compaq Presario CQ62 ?

You change the bootdisk in the BIOS to the cd. Then boot from the XP CD. And press a key when it tells you to. However, this will wipe Windows 7. So, if you want anything copy everything you want (except programs), before you format the hard drive.

Also, NOTE: XP doesnt have drivers for most of whats on the system (LAN/Sound/Card reader etc). So, if this is the only computer you've got, go to the HP site search for this laptop, download the drivers and copy them to something. Before you start. Or you wont get back on the internet..

Also NOTE: If the hard drive in this is SATA, you'll have to disable AHCI in the BIOS (change it to IDE mode). Or XP will crash before you get to the setup screen. Unless you download the SATA drivers, unzip/extract them and add them when it says to press F6 (on a floppy).

The XP CD doesn't have SATA drivers on it either. If you dont add the SATA drivers during the install, DON'T change it back to AHCI after you install XP. Or it'll crash

Also, make sure you've got an XP key. A windows 7 key wont work
