Yesterday, a friend tried to install a Dell laptop cu Windows Vista pre-installed Windows 7 build 7100. I was there when he did the installation, but had to talk on the phone and explain what to do to install Windows 7. (His level of knowledge in the installation of Windows being quite small.) He had Windows Vista installed and was going to install Windows 7 from a bootable DVD.
A clean install was done, avoiding trying to upgrade from Windows View the Windows 7. The files from Windows Vista were automatically moved by installer the 
Windows 7 folder Windows.old. Everything went normally during the installation, until the last phase, when it appeared error: Bootmgr is missing. As the last phase of the installation, there was no chance of entering the old operating system and the display had no option.
He repeated the wealthy, but no result. To complete installation of, Bootmgr is missing.
Solution: (on the phone)
him - How are you? install again Windows Vista? bootmgr is missing again…
I: - ppfff… no… Hold down the Shut Down until the laptop shuts down, then restarts the system. Do not press any key. You let him see what he's doing.
him (after a while) - mergeeee !!
Good. I didn't understand much, and why the error appeared in his situation. On Windows Vista, the error can be corrected with Installation CD, but on Windows 7, it seems like a simple cold restartIs enough. :)
If you know a real solution to this problem, please leave comments ;)
