Changing Space on partitions

[Fritzy]

Hi all, I have bootcamped W7 with 70 gigs; but want to change it to have more space for games. I think I have to Delete the whole partition and then reinstall/bootcamp my W7 Disc, but will my key work with it?

You cannot officially resize the NTFS format, although apparently with the right tools some people have successfully done it. I tried, everything was in tact, but it wouldn't boot.

The best option would be to reinstall. Your license key will still work after the reinstall. (Source)
