hi everyone. i am planning to upgrade my hp pavilion dv2820tx to windows 7 from the factory installed vista home premium. however i wanted to create the recovery disc just to be sure. after doing so i found out that the first disc i created is corrupted and i couldn't make another one. i have read that are some people able to reset this limit. i have tried using resetrmc.exe but it didn't work for me. can anyone please help me? i just don't want to upgrade to windows 7 without a chance to go back to vista if anything wrong happens. thanks a lot!
