I installed 12.04 64bit with the WUBI installer on a Windows 7 with Check Point Full Disk Encryption.
The WUBI Installer runs without any trouble selecting the compatibility mode with Windows XP and as Administrator.
The problem is that after the installation is complete and the reboot done, when you restart the system, there's no option to start Ubuntu instead of Windows.
I recently installed Ubuntu on other Windows 7 machines without any problem. But those laptops don't have the Check Point Full Disk Encryption. And when you restart the system you have the option to start in Ubuntu.
If somebody has resolved this issue please share.
