I use Windows 8, but I also want to use linux based OS. I use DELL Inspiron 14 laptop, series 5000. There's an ubuntu sticker here. Does that mean ubuntu is downloaded? How to get sure/use it then? Please tell, I don't know. If not, then what should I do?
If your laptop has Ubuntu installed as well, it will give you the option to choose which one to load on boot screen, as
jedishrfu points out. You have nothing to do to see this. You can also check if your hard disk is partitioned and the
properties of your hard disk, as an alternative way to see if another OS is installed (NTFS is for Windows, ext2,ext3,ext4 for Linux etc.).
On the other hand if it is not installed, you can do what
newjerseyrunner recommends, but keep in mind that Windows are not too friendly to multi-boot configurations and particularly to
GRUB and if you don't know how to do it, the process may end up corrupting your boot sector. A more safe way, is to use a virtual machine - like VirtualBox or other free such software and use your machine as a "host". You'll have a sufficiently well isolated OS, inside the virtual machine, that is
fully operational, with a cost on your machine's resources and the boot time of the hosted system, but given todays available resources, there will be no notable problem whatsoever. This way, you can experiment with more Linux flavors and other OSs as well - you can check which OSs a certain virtual machine supports, in order to decide which one to download and install.
