I have got a new Samsung Series 7 laptop with Windows 8 where I tried to install Ubuntu. It is a 64-Bit system which uses UEFI and has "Secure Boot" switched on in the BIOS by default. After I switched if off (and set it to "UEFI and CSM OS") I was able to install Ubuntu (Ubuntu 11.10, which recognized Windows as Windows Vista, although it is Windows 8), by booting from CD with Settings/Change PC Settings/General/Advanced Startup in Windows 8. But after the installation and the restart of the machine somehow ignored Ubuntu and booted only Windows 8. Then I tried to reinstall Ubuntu 12.10. It still only boots Windows 8. Then I tried Boot Repair, which was not really helpful. Any ideas how I can create a dual boot system with Windows 8 and Ubuntu 12.10 ? Here is the link that Boot Repair generated: http://paste.ubuntu.com/1368624/ Is it necessary to create an extra EFI partition with GParted?

I know that Ubuntu +1 questions are frowned upon, but this I believe is a fair exception.

This has meant in the past that I had to rely on a custom iso to install… >>> More

How will people upgrade from 12.10 to 14.04 after 13.04 is EOL?

Looking at https://wiki.ubuntu.com/Releases 13.04 will reach EOL in January 2014, while 12.10 will reach EOL in April 2014, therefore if a 12.10 user hasn't upgraded to 13.04 and subsequently to 13.10, there will be a 3 month period where a 12.10 user has a supported version of Ubuntu, but will be… >>> More

How do I know if I am running Wubi or a proper dual-boot?

I tried to setup a "proper" Windows/Ubuntu dual-boot system, by installing Ubuntu from a USB key. However, I simply could not get the laptop to boot off the USB despite the fact that I made the appropriate changes to the boot device order in the BIOS. So I then turned to Wubi, and (to cut a long… >>> More
