I would suggest you to make new partition and install windows 8 there for a dual boot. This way you will have both Win 7 and Win8
Just put the windows cd in and restart pc, when prompted choose the new partition and install it there

All Windows 8/8.1 computers come with a restore partition. You should be able to reinstall Win 8 from that.

If you blew away the restore partition, or you want to set up the computer a different way than the factory default, you can still create a Windows 8/8.1 recovery flash drive by using your Windows key and downloading the 4-8 GB recovery image from Microsoft.

Instructions for finding your key and creating recovery image:

If you did not format the HP recovery partition, you can use that to restore the Windows 8 factory install. Otherwise you will need Windows 8 OEM installation media.
