I've got a Samsung 900X Ultra-book with Windows 8 Pro preinstalled and wanted to install Ubuntu 13.04 alongside (as dual-boot) from a DVD which came with a Linux-Ubuntu special edition of a magazine. But i cannot make my ultra-book boot from an external dvd-drive. I already looked into the UEFI-Firmware Settings. But as I am a total newbie, I am not sure what I have got to change in order to be able to boot from a different source than my ssd. Can somebody help me?
May be this can help you. Just try once..
You have to follow these very simple steps..
Connect your external HDD and start your system. This time boot from your Ubuntu LiveCD/DVD inserted and select 'Try Ubuntu' (not 'Install Ubuntu'). When system starts open ternal (CTRL+ALT+T) and execute following commands:
Installing boot-repair ( a good s/w to fix grub ):
When started select Option 'Recommended Repair' from out of two options:
'Recommended Repair' & 'Advanced Options'.
Follow very easy onscreen instruction, it will build/fix your grub..
Restarting your system may list all the Operating Systems installed in your all HDD.
Be sure that you have properly shut down your Windows 8 OS, before starting these steps.
