I recently purchased Dell Inspiron 5548 with a pre-installed Windows 8 OEM on a HDD 1TB with Single Partition. Is it possible to install Ubutnu 14.04 on it? Is there issues related for my model for bluetooth, wifi drivers and working?

How can I partition the disk into multiple partitions so as to install Ubuntu 14.04 on separate disk partition. I don't want to remove Current Windows 8 completely ( as I need it to use softwares like Photoshop etc).

Also my laptop comes with 2GB ATI Graphics Card, will I able to get benefits/ use graphics card in Ubuntu? Do I need to install proprietary drivers in Ubuntu to use graphics card? If Yes, where can I get those drivers for ubuntu?
