Do you still have the Product Key with COA for the Win7 you bought but didn't use? Does it have SP1 included in the DVD? It saves hours of updating to have an installer with SP1 which we can help you with.
You can copy out any stranded files using Win7 DVD: Copy & Paste - in Windows Recovery Console
Later you'll want to have your son find the packaging, email with Product Key or bank information for his online purchase so he doesn't throw away a $100+ OS.
