Windows 7 - Delete partition

Hello Friends I have installed a fresh copy of windows 7 in My D Drive.My OS drive before was C Drive. I didn't want any back up of old OS system files, so I decided to install fresh copy in another drive i.e D.But ,now when I try to format my old C Drive ( inorder to remove 2 options of windows 7 while booting & empty the drive) , it gives an error that windows cannot format drive.When I try to delete folders inside that drive , i get message " You require trustedinstaller permission to delete this file" What does it mean?

Hi,

The 'trustedinstaller' is the main system installer, which created & installed the files to the HD during installation. You can take ownership of the entire C drive (Right-Click C: -> Properties -> Security -> Advanced -> Owner) but there will still be some critical system files tied into C.

I believe BCDEDIT can configure D: to be your uninterupted boot drive but I'm no BCDEDIT guru

i tried formating c Drive ..but still

So is this the new win 7 or the old win 7? did you try using BCDedit like orbital shark sugested? who owns the recycle bin (right-click properties, look for owner)?

Ken

i'm in new win 7.When i run BCDedit , cmd prompt comes and disappears in fraction of sec.

You need to have command prompt open 'As Admin' then type BCDEDIT /? for a list of commands. Best thing to go is check out

BCDEdit Commands for Boot Environment

ok..when i open cmd prompt from ADMIN , BCDedit opens , but what exactly should i do ?

Sorry I gave you the wrong link, try this

BCDEdit Command-Line Options

pls can u tell what exactly should i look for ? The link which u gave have commands explained.

can you post a screenshot of what is displayed when you type BCDEDIT please?
