WINDOWS/SYSTEM32/CONFIG/SYSTEM

Hi . I would be so gratefull if someone could please give me some addvice. Im a single mum of 2 boys , I saved up and bought them an acer apsire one netbook each for xmas. Already iave had to send one of them of to acer to have it repaired , due to a fault on there part. Whislt my eldest son was using his a few days ago , my much loved staffy jumped up to say hello to him , knocking over a glass of water. In panic my son dried to dry it using my hairdrier. It did work fine for a day , then certain buttons stopped working. Now when it turns on it says that there is a corrupte or damaged file , so windows will not boot up. It is asking me to insert a cd, which i didnt get. What id like to no is , is it possible to create a recovery cd on one of the netbbooks to use on the other ? . Both have indentical os information . I do also have a genuine xp disc for my desktop, but as i understand netbooks have a oem os . If i were to reformat the netbook with my disc am i still able to use the validation key reg to the netbook. I really can not afford to buy another netbook or windows disc. Thank you for reading this rather long mess,i hope someone can help me :-) ....
