Done it !
With proper acknowledgement to someone called “Raymond” on an Ubuntu forum I managed to by-pass the need to use the Administrator password and then resized the hard disk C: back to the original 60 Meg
Just in case any other Wiki member meets the same problem I give the instructions below
First: to repeat WHY this procedure is needed
Ubuntu installs a boot loader called GRUB into the Master Boot Record (MBR), if you delete Ubuntu partitions all the data will be deleted but not GRUB! So when your restart your pc GRUB will look for Ubuntu , when it does not find Ubuntu it show some error and you cannot even boot into windows.
1. Go to the web and download using Easeus Partition Manager. The (free) download will put an icon on your desktop. You will need to access Easeus laterhttp://www.download.com/Easeus-Partition-Manager/3000-2248_4-10863346.html
2. Download mbfix http://www.download.com/MbrFix/3000-2094_4-10485990.html
3. Extract all files in mbrfix.zip to c:\ - or to whatever is your primary boot disk that holds Windows. Normally this will be C:
4. Open Command Prompt using start->run-> type cmd -> OK
5. Type cd \
and press enter
6. Then type mbrfix /drive 0 fixmbr /yes
and press enter
7. Exit the Command Prompt by typing Exit and press enter
8. Open Easeus Partition Manager
This will show you graphically the set up of partitions on your machine
9. Click on the main partition ie the one holding Windows, and then on “resize/ move partition” from the left hand window
10. The sub-screen that opens also shows the partitions on your disk. However, you can now ‘click’ on the partition boundary and drag it so that the partitions are resized how you want
In my case I wanted to drag the boundary so that the partition was removed and all of C: drive was available to Windows/ data
11. Click Apply and then follow the rebooting instructions
Your machine will reboot into Windows but then shows a “safe” Easeus page asking to confirm that you want to progress. There will be a couple more reboots but finally you are back into Windows with a disk resized as you wanted.
Some of those reboots are slow – keep your hands off the keyboard
So, it all worked for me. I still have NO IDEA why the Windows “repair console” route would not accept my totally valid Administrator password.
