I would like to reinstall windows Xp (an original version). Thing is i'm not formatting my drive. I've got 4 partitions C,D,E,G (F is cd drive ). G contains the OS. Since I've a lot of data and cannot take backup of them (anyway it'll take ages). So how do I go about it? PS :- I once overwrited on the existing OS which was in C. That is why it became G in the new OS. What happened was the pirated key got installed in the new os even though i had put a NEW Original key!!
