    Quick rundown of what happened:

    My desktop has 2 hard drives, 1TB and 320GB. I have Win 7 installed on the TB drive, and I use the 320GB drive for testing. I previously had a full installation of Server 2008 Enterprise on the 320GB drive. Yesterday I went and installed Server 2008 R2 on the 320GB drive. Now the Win 7 drive won't boot.

    Now this is what happens, if I have both drives plugged in Server 2008 R2 (Core installation, so there's no gui just a command prompt) boots up with no options (straight into the OS, doesn't give me any choices like it used to), doesn't matter which drive I list as first boot. If I unplug the 320GB drive I get no boot at all. I ran the Win 7 disc and when I get to the repair screen it doesn't show an OS in the window to repair. I can get to a command prompt and see that everything is there, but it won't boot. I tried running the Startup Repair and oddly enough it says it found a boot partition error and that it fixed it, but it still won't boot.

    Any idea's? I haven't had to deal with Win 7 boot issues before (I'm used to just fixing the boot.ini). When I had previously installed Server 2008 a few months ago it just modified to boot options to show me both Operating Systems and I could just choose. Not sure why 2008 R2 pooched the Win 7 startup.

    I'm really trying to keep both of these OSs intact if I can. I did a couple hours worth of configuration and testing on the 2008 R2 server that I'd prefer not to lose. I also really don't want to reinstall 7 as I only backup my files and I don't want to have to reinstall all my programs again (just finally installed the full version a couple weeks ago when the beta expired). This might make me start looking at doing an image based backup...

    Did you try (both in Server and in 7) Control Panel > System > Advanced > Startup and repair options > Check the option to display os boot entries ?

    Windows 7 couldn't boot at all and Server 2008 R2 is a Core installation (no gui, just command line) so I couldn't check that.

    I did get it working, but I honestly don't know how. I went in through the WIn 7 install disc and ran through the repair options. At the first screen it wouldn't show an OS at all, but when I did the startup repair it showed a boot partition error. It said it fixed it, but even after running it at least 5-6 times it still wouldn't boot. I was then trying to figure out what happened by using bcdedit, but the Win 7 HD showed no BCD store at all. I went through these instructions to fix it: Boot Trouble - The NeoSmart Forums but couldn't get it to create a bcd store. After running through the startup repair a few more times I ended up giving up, as there's no way to boot Windows with no bcd store. So I used xcopy to copy the few files I know hadn't been backed up recently, ran the startup repair one more time (it gave me the same results as every other time) and rebooted. I was pretty much ready to install Windows again and it just booted up like nothing had happened. I have no idea why the startup repair worked on probably the 11th or 12th time, but it finally worked.

    At least it's working now, but I seriously have no idea how. I haven't checked my Server 2008 R2 installation yet to see if it's working. At least if that one is dead it'll be easier to redo than my desktop would be.
