Windows 7: BOOTMGR is missing

Add the HD's back one by one to see if one blocks Win7 boot. If so, you can then boot the DVD Repair console or Repair CD to use DISKPART from the Command Line to deactivate the partition responsible.

This can be determined by detailing each HD with DISKPART, or if you want a graphical display of all drives and the ability to manage/delete/resize/convert/wipe/activate/deactivate/explore/recover data use free Partition Wizard bootable CD. You want no other partition marked Active or System.

If you had GRUB on any HD, it can also interfere with Win7 boot and needs to have data moved off and deep cleaned using Diskpart or PW CD.

But now that you're installing, let's wait to see if they interfere.

I have unplugged all other drives, and I'm in the process of doing a clean install on the single remaining drive. I believe this will work, but what will happen when I plug in the other drives? Will it once again find the old files and hose up my new installation?

After the reinstall is complete, it will be simpler to make the HD containing 7 first in the bios boot order.

I did the reinstallation on the single drive, then I plugged the other drives back in. Everything is working fine now. Thank you to everyone for the great ideas and the help. It's nice to know there are people who can share their expertise here. Thanks!
