Okay First off, I am using Windows 7 Ultimate RTM. Anyways, I have an interesting issue since I clean installed from RC1 to RTM. The issue is that when booting the system without the Win7 RTM disk in the drive it fails to load with a missing bootmgr file. As soon as the disk is in the drive, and reboot or startup, it will load fine and I am back to work.
So Disk in drive it boots, no disk in drive no boot.
I have tried the windows 7 repair utility and it hasn't fixed the issue yet. On a second hard drive I have some old windows 2003 boot records(and setting that drive to default it tries to load win2003)
