Obviously we don't want you do anything to compromise the running of a working computer!
But making the HP Recovery Media is a priority.
Here's a link to the Support Home Page for the product with tabbed sections for drivers, troubleshooting, user guides etc.
HP Pavilion g7-2341dx Notebook PC support
Here's a link to the HP User Guide Manual for your model .
And here's the Maintenance and Service Guide which overlaps on some of the recovery stuff buy is invaluable for it's exploded view of components in case you ever have to change anything after the warranty expires and it gives detailed specifications for different models of the g7.
They are worth downloading as pdf files and keeping it on the computer even if you have a paper version.
In both those manuals you will find full details of exactly how the HP Recovery Manager works including how to access it from the Start Screen so make sure you have a bunch of DVDs (not RW) and do that before trying the poker game again.
I'm having difficulty on pinning down the way to make the Windows 8 Recovery disk other than on a thumbdrive since there option to make a disk seems to have disappeared. More tomorrow I hope.
On that Support page, under Troubleshooting there is an Alert which you should read:
Windows Update 2756872 Hangs at % (Windows 8)
Installing the KB2756872 or KB2770917 using Windows 8 Update can cause the system to hang at 12%, 13%, 14%, 15% preventing the update to install. Follow these steps to troubleshoot your system and complete the update.
You might run into this since I've heard of people reporting this including here in the Norton Forums I think. Not to do anything unless it happens to you. The procedure they describe is relatively simple!
Let me know if you have any questions and/or how you get on.
