Solve UEFI Boot problems by using rEFInd Boot Manager

I bought new Notebook Lenovo Z585 last year which came with Windows 8     pre-installed. The laptop is UEFI enabled and many of PCs/Notebook nowadays that come with Windows 8 preinstalled are also UEFI boot system.Initially I had problem installing Linux distros and having stable boot system.Finally I was successful working environment with Ubuntu 12.04 and Fedora 18 with some tweaks,you can refer my UEFI Dualboot guide.
Fedora and Ubuntu till date have better UEFI support than other Linux Distributions so if you are planning to installing Linux choose between them.
While reading through websites regarding help on UEFI ,I came to know about rEFInd Boot Manager a boot manager modified and built out of rEFit built originally for Mac.
