Cannot reboot window7 after installing VirtualBox + Ubuntu

[guifson]

Hi All

I am unable to reboot my window7 OS after installing VirtualBox + Ubuntu 11.04 (at least I can access the secure mode but don't really know how to solve the issue).

Please can someone advice on how to recover my OS?

Thanks for your help

Did you install Ubuntu inside VirtualBox or by booting your PC to the installation?

Thanks

I install Ubuntu inside VirtualBox and everything was working fine during but when I switch off the computer, the following day, it was not possible to reboot it

That has nothing to do with VBOX or Ubuntu.

Ask a friend knowing something about computers.
