And this is unexpected? I'm assuming you installed Win7 as an upgrade to Vista, so I fail to see how this is unexpected behavior.
Today, I installed a copy of Windows 7 onto my machine which is running fine, but now I am unable to boot Vista. When I select Vista at startup, I get the loading bar for about a second and then my computer restarts. I have tried to use System Restore but it does the same thing, and Startup Repair just continues to say that it is attempting to fix the problem but it does nothing. Is there anyway for me to fix this? Also, here is a screen from my Disk Management. I do not know much about this so I don't know if you can identify the problem from there. Thank you.
