I've followed all the instructions and when I get to dual screen boot I choose Ubuntu and I receive a message: 1. Insert Windows Installation Disc and restart. 2. Choose Language end then press next. 3. Preess restore device.
If you don't have this disc get in touch with system administrator or the manufacturer.
Info: There's a file missing or it contained an error which is preventing from booting the OS.
Enter= OS selection Esc UEFI configuration
Please help me on what to do to complete the installation. Thanks
