Windows 7: Can't Delete unwanted Win 7 OS files

29 Dec 2009   #11

Vista Ultimate X64/ Windows 7 Dual-boot

I have two 250 gig hard drives. When I told it to format C: and overwrite the OS it did not do that, instead for some strange reason it changed my C: drive letter to E: and then installed the OS on the other drive leaving me with two copies of Win 7 Ultimate
It" will not decide to do this on it's has to be prompted to install a 2nd instance of the OS.
Must have been something you clicked.

And to stay with what's already been good information, it's best unhook any extra drives so your first prob doesn't accure again. That way when you install the os it will be C:/

Try booting a Linux "Live" CD like Puppy Linux or one of the other bootable CD packages like EBCD, UBCD or best of all, UBCD4WIN. See if you can access the hard drive that way. If yes then you should be able to delete whatever you don't want.

See this post by Happyrck on GeeksToGo for Puppy Linux:
Get the latest version available as the one he recommends is no longer easy to find.

These two are iso images you download then use your burner software to create the bootable CD from:

Ultimate Boot CD

This one you have to build on your system and you need a Windows XP Home, Pro or MCE CD. Takes a bit of work to set it up but it's not difficult and when you boot it, you have Windows XP:

I've not tried to build this under Windows 7 so don't know if it will work that way or if you need a booted XP system to create it from.

Exactly, we're seeing a lot of DISK0 data drives that grab the active flag somehow and end up System drive.

The fix BTW is to deactivate data drive, mark Win7 drive active, boot into Win7 DVD and run Startup repair 3 times to rewrite the MBR to Win7 partition.

The best tool for this is free Partition Wizard bootable CD so all partitions can be easily checked for Active status to Modify:Set Inactive, before Win7 is Set Active.

Win7 Ultimate 64 bit Build 7600

Using a Linux boot disk is a great idea I wish I had thought of it earlier. I'll let you know how it turns out.

I liked your suggestion best because of the ease of the solution. I down loaded Paragon Partition Manager 2010 64 bit FREE Edition formated the hard drive and did a repair of my Boot Manager and all is well in computer nirvana.
Thanks Road Runner
