Hello misdirection,

there are several reasons why it's generally a bad idea to install multiple operating systems on one an the same media which I mostly covered in other posts here on Launchpad. Among these are the much too high maintenance costs, silent data corruption and more...

I strongly recommend you to ether backup your data and then recover or reinstall your system. Of course there are more beautiful way to get your system repaired. However I doubt you can do this with a lack of technical skills. Maybe you'd get some professional help?

From a technical standpoint of view I think it's not a partitioning problem. In case the boot loader also works you may have created a problem with SDC or something. Maybe you can boot from a windows CD and go to recovery mode (F3 or F5) and then spawn a shell. Try to enter "fixmbr", "fixboot" and "chkdsk c:" from there. It may help.

Currently, are you able to boot Ubuntu ?

Please provide partition table.
If you can't boot from hard drive, boot en Ubuntu CD/USB stik and then choose "Try without install".
Open a terminal: you can either press Ctrl+Alt+T or Applications->Accessories->Terminal.
To copy/paste in a terminal, replace Ctrl+C by Ctrl+Shift+C and Ctrl+V by Ctrl+Shift+V (for historical reason, Ctrl+C is assigned another function).
Paste to terminal the following commands:
    sudo fdisk -l
where "-l" is lower case "L".
Copy/paste result into a new thread post.
