If I have 1 physical drive, organised into 3 primary partitions, with one of those being a system partition and EVERYTHING else split over the other 2 partitions, so that there's nothing but Windows on that 'system' partition, will I be able to, providing I back all the relevant application data, simply be able to reinstall Windows on that partition, and still be able to access the data and use the programs on the other partitions once I've restored the backup?
