Here is my situation. I installed Windows 7 RC a year or so ago on my second drive while running Vista on my main drive, just to test Windows 7. Since then, I have of course upgraded my main drive to Windows 7, and no longer need Win7RC on my second drive.
I have removed it from startup options, and deleted all the files I could, from the following folders: program files, program files (x86), users, programdata and windows.
However, in all of these folders, there remain other folders and files that I cannot delete, no matter what I try.
So far, I have tried safe mode, I have tried to load PELoader and access the drive completely without any OS, I have tried the attrib command, and even with the attrib command, it says ACCESS DENIED.
There are about 10GB of folders/files in the Windows folder, so that is quite a bit, and about 1GB in the other folders I mentioned.
If everything else fails, I will format the drive, but I would really like to do this properly so I know how to proceed in the future. I can't believe even attrib won't work, these files are seriously protected, somehow, even tho they have nothing to do with the OS that is currently running. How is that even possible?!?!?!
Can anyone help?
