[ubuntu] Wireless Connection and Booting Issues after installing Ubuntu in Dell Inspiron 14

view story

http://ubuntuforums.org – Hey guys, I've just got a new Dell Inspiron I14-2530p with native Windows 8, and decided to install Ubuntu for a dual boot. I had to change the bios settings to Legacy instead of UEFI Secure Boot (I don't know very well what that means, but was the only way I found to boot from the CD-ROM). I've used an old live CD I had for Ubuntu 9.10. The booting went fine, and so did the installation. At the end of it, I clicked the button to restart the computer, but it took too long, and I had to turn it off. After I turned it back on, no GRUB menu was displayed, but I've got that worked out alread (Hardware)
