Installing Ubuntu v10.04.1 LTS 64-bit

[UncleAaron]

I was installing Ubuntu, and I think I've got myself a problem.

I have Windows 7 installed on my computer. The partitions were setting up as follows:
100 MB for the boot sector
687 GB for drive C:
15 GB for Win7 drive image

This is what I did. I went to "Disk Management" and shrunk the volume for drive C to make a 100GB space for Ubuntu. I left the space "unallocated", rebooted the computer using the disc that I made with the 64-bit version of Ubuntu. I clicked the button to try out Ubuntu. When I got to the desktop, I clicked System > Administration > GParted.

I selected the "non-allocated" 100 GB area to have GParted to partition for Ubuntu.

Here is where my problem is... after partitioning the area. I go to System > Administration > Install Ubuntu 10.04.1 LTS... I follow the prompts and when I get to the step to install to a partition...nothing shows up in the box for what partition I want to install to. So I shut the computer down, take out the Ubuntu disc, and the computer freezes.

I put the disc back in to reboot to Ubuntu, run GParted and instead of seeing all the available partitions... I see 1...yes 1 partition that is 687 GB that is "unallocated".

I'm guessing that Win7 is completely off my computer. What the heck??? 

How can I get Win7 back??? My computer didn't come with a disc. I guess I'm screwed!!!

What should I do now???

Can you boot into Windows 7 at all?

No. After CMOS, I get a flashing cursor in the top left-hand corner.

Can you boot into Windows 7 at all?

For me to help you, here is what I'd like you to do:
Boot into Ubuntu with the Live CD,
go to System>Administration>Disk Utility,
on the left sidebar choose your disk drive,
take a screenshot (Print Screen key) and post it on here.
