This is where the confusion always starts. ANY version of windows will consider the partition that IT is on to be Drive C. This means that when you are in Windows you are trying to delete the current running operating system, which it wisely will NOT allow. Look carefully at your partitions and write down the exact SIZE of these partitions and use THIS as the criteria for deciding which partition to delete. In other words, If the original version of W7 is on a partition that is say 250GB and the added version is on a partition that is say 223GB, then when you go into Disk manager in the first version, the second will show up as 'D' 223GB but if you go into disk manager in the newer version, the original will show up as 'D' 250GB. Please note that after you delete the version of windows you do not want, you will have to go into msconfig and remove it from the boot tab also to prevent the option from showing up on start up. If for any reason you cannot boot back up after removing one of them, put in your install disk and do a repair to fix the boot partition.Then reallocate the space as needed, though if the unallocated space comes before the working partition, you will not be able to add it together with windows disk manager, so make a new partition for other purposes like files or back up, etc.

You have to be a little bit crazy to keep you from going insane.

I use a live linux cd to delete the darn thing.

Might be able to use command line partition tool in W7 to delete the partition.

Hi Fingers

I am sure I am trying to delete the correct copy, it deletes a lot of files before the adm refuses me, I have taken ownership a few times but still no luck

Are you using disk manager to just delete the entire partition? Then you would just create a new partition from the remaining space.
If you still have trouble, do as Jefro suggests, use live linux disk, boot to it and delete the entire partition from there. Just use Disk Manager to recreate the new partition in NTFS though after.
