HP USB Recovery utilty on your Support page should get the Recovery created:
For some odd reason,your Specs page doesn't mention what size hard drive you have:
You will need to find it manually. You can use Disk Management to view the hdd and determine approx size or you can remove it and check the label. You should get one of at least as large a capacity as the original in order to use Recovery Media. It can be larger but not smaller. For instance if you have a 320GB you could use a 500GB but not a 250GB.
