I had installed two os in two different drives due to my computer problems. Now the computer is ok, but i don't know how to del my os in my d drive. I want to keep the os in my c drive...do you know how to uninstall os in d drive the right way?
This is unbelievably easy to do. Boot from the C: drive, the double-click My Computer and the D: drive icon. Look closely and verify you're opened drive D:.
Right-click the Windows folder and click Delete, then confirm you really wish to delete the folder. You'll be reminded that it's too big for the Recycle Bin; choose to continue.
When done, right-click the Program Files folder, and click Delete. Continue as above, then close the D: drive window. Done.
