I had Debian 6 on my machine (Dell Vostro 260) and used GParted to shrink the partition. I then tried installing Windows 7 on that partition. After Windows 7 installed, I could not choose which OS to run. It would just boot into Windows.
I ran GParted again, and saw that Windows created another partition, labeled "System Reserved". That partition had the boot flag set. I tried moving the boot flag to other partitions, including my Debian partition and one with a file system "linux-swap". No option would actually load an OS or anything except for the Windows partition, which is not what I want.
Is it worth it to try to fix this installation, or should I start over. I have all my data backed up, so I can easily install from scratch if I need to. If I do start from scratch, which OS should I install first? And then, how do I set up the partitions to install the other OS?
Let me know if you have any questions. Thanks for your help.
