I tried to install Win 7 64 bit on a new hard drive. I got to the "Enter the key" message and when I did this the system restarted and I got 20 mins of hard drive activity but no signal to the monitor. I was unable to boot from the DVD and I ended up trying to wipe the drive using my laptop. I now get the bootmgr missing message and I cannot get the system to start from my DVD drive. I have tried to change boot order in BIOS to no avail.
I don't think that my laptop was able to wipe the System partition of 100MB that 7 originally set up at the beginning.
