Windows 7: removal of windows 7

hi,
i had a beta version of windows 7 and then i installed a legal new copy on another
drive. i have a dual boot where i can choose between the two versions.
i want to remove the old one completely. how do i do it correctly without harming
pc and losing space?



thanks

Easily, just use this tutorial to edit the system so that you only load into the new Windows 7 partition.

BCDEDIT - How to Use
Dual Boot - Change OS Name in Windows Boot Manager

After that, just delete the old partition with the Drive Manager found by right clicking My Computer --> Clicking Manage --> Clicking Drive Management found in the list on the left.
