I've a Windows 7 working for a while. I tried to install Ubuntu 10.10. I did a shirnk on the Windows 7 partition so I could install Ubuntu. Started installation, chose automatic partition. It went through installation smoothly, but whenever a start de computer it always goes to Windows 7, the boot loader never shows up with options on what OS I want to go.
Basically, Ubuntu is installed alongside a Windows 7, but I can access it.
Windows 7 was not harmed on the operation.
