Ubuntu :: Can't Get Win7 To Load?

I can be somewhat long-winded at times and I'd rather give a full account of the problem I've always used windows as an OS but have been curious about Linux for a while now, so after looking around online I decided to try ubuntu. I have an Asus EEE PC netbook that came with win7 already installed on it. Last night I downloaded the netbook edition of ubuntu via their website, burned the .iso to a disc via my external dvd drive and then ran the demo. I couldn't get it to boot off the disc when I rebooted, so I had to pick the third option which I think installed some files to the computer in order for me to be able, to run the demo. When it finished that and I rebooted, the dual boot menu came up with both win7 and ubuntu on it. I messed around with ubuntu for a few hours before deciding I wanted to keep it on my computer, so I ran the full installation and selected the side-by-side installation. I remember when the installer asked about the partitions. I wasn't sure what to do as I wanted to keep both windows and ubuntu. There were three options: 1. Install them side-by-side choosing at startup 2. Erase and use entire disk 3. Specify partions manually (advanced). I wasn't sure how much space to allocate ubuntu, so I chose the first option thinking that it would just give me a default amount and would probably be plenty to effectively use the OS. After installation, it asked if I wanted to continue testing ubuntu or reboot and start using the full version. I rebooted, and it gave me no option for windows 7. In addition to this, the update manager came up and told me there were some 200 or so updates available. This is always common with windows when you use it for the first time, so I tried to update, and an error came up telling me that I needed at least +500mb free space for the update and only had 400mb or so. I'm a bit confused, and I've since tried rebooting several times, but windows is still unavailable.

I guess what I'd like to know is why win7 isn't listed in the GNU Grub at startup, and how I can fix that. I would also like to know how I could go about getting more disk space allocated to ubuntu. I thought about just uninstalling it, and then reinstalling it and giving myself 10-20gb of space when asked about the partitions again, but I obviously can't do that right now. The only other thing that I could think of was doing a factory restore for my netbook to get windows back, and then reinstalling ubuntu once again. I wasn't sure that would work though and didn't want to take the chance without getting the advice of somebody much smarter than me.
