Tricks how to solved Initramfs error and can't load Ubuntu OS

My Ubuntu OS 14.04 was in trouble and can't boot properly.

It was happened when I was trying to configure my GRUB file to figure out  how to resolved my webcam issue.

I know that this is a boot system file but after editing and saving the file, I forgot to issue a command grub-update to update my boot file.

This is the only reason I know why my OS was not open properly as expected.

I couldn't afford to loss my OS because I don't want to loss my file and the settings of my Kubuntu OS, obviously I don't want to end up to re-install my OS from the start again.

 I am very thankful that I found my live cd OS which is installed in my usb stick.

I'll just want to share with you guys what i did to resolved this issue.

•  Insert usb to a Laptop (mine is HP Probook 4430's) and power it on, and while it's booting press [esc] and press [f9] to show the boot option, in selection click to select boot from usb drive option. Note: Other Computer has other way/keyboard to press for booting from usb options.
• After the live cd OS successfully loaded, click the try ubuntu then press ctrl + alt + t to open the terminal window
• On the terminal window issue the following command,  

1. sudo add-apt-repository ppa:yannubuntu/boot-repair
2. sudo apt-get update
3. sudo apt-get install boot-repair
