Let me explain my problem in as simple as i can. I have a desktop PC with 4 partitions. Earlier i was using Windows XP on C drive, later installed Vista RC1 on D Drive. yes, it was Dual Boot. Now i have uninstalled XP and installed Vista RTM to C Drive. So i have Vista RTM on C and RC1 on D.
Now i want to remove Vista RC1 from D partition. To do the same, i simply deleted all folders in D drive except Program Files, ProgramData and Windows because these files are not deletable. Whenever i try removing them it gives me an error message saying "You need permission to perform this action". I dont want to right click the drive and format becais eit contains few important data folders as well. I also changing ownership to admin group, as well as give full rights to admin group to these folders but no help.
Furthermore i also changed the owner of a folder from TrustedInstaller to admin. Due to some reasons i now need to set TrustedInstalled back to the owner, but I can't find it when using "Select users and groups". Hence i need you guys helps regarding these two stuffs.
First please let me know how can i delete those undeletable folders from my D drive? and secondly what is the correct location of TrustedInstalled ?
Please help.
