Your advise seems to very badly thought out if you have thought about it at all that is, you would see him loose both his OS's and all his Data without even trying a few simple repair/recovery steps.
I also installed Windows 7 from an ISO many times and I also dual boot with Vista and I am sure that having Vista has nothing to do with his problem and deleting his only working OS will not help in any way, also the RC can still be used for some time and can only be obtained only as an ISO, plus like myself you can also get the RTM as an ISO if you are a Technet Subscriber.
