Yesterday I setup ubuntu on my lenovo y330 notebook which originally had windows vista installed. I had to try different setup methods before finally getting the ubuntu installation to work, but the method i used in the end was the simplest and it worked superbly!
First step - backup your current system. I already had windows vista installed on my laptop and wanted to make sure that if the ubuntu installation process messed up my system somehow i could easily return it to previous state. Luckily lenovo notebooks generally come with a 'One Key Recovery' system that you can easily use for this purpose. I used the 'One Key Recovery' software to make an ISO image of my current system and write it to a dvd ( i needed 2 dvds for this). Now i had nothing to fear!:D
Next ubuntu installation
method 1 - tried to install from CD. Didn't work:( The machine booted from the CD woth no problems but when i selected the option 'install' from the menu nothing happend! none of the menu options worked. Thought perhaps the CD i used was faulty so downloaded ubuntu ISO image from www.ubuntu.com and wrote to another CD. Had same problem with CD no. 2 so gave up on this method!
method 2 - tried to install using wubi installer for windows ( www.wubi-installer.org). downloaded the installer and ran it. installer ran with no problems. i could select the partition on which i wanted to install with ease. next the installer started downloading the ubuntu iso image, the program showed 3 hrs 17min to download! this frustrated me becoz i had already downloaded the ISO image to write the ubuntu CDs! luckily on the wubi installer page i found an option for install with previously downloaded ISO image. this lead to method 3!:D
method 3 - copied wubi installer .exe file and the ubuntu ISO image i had downloaded to a folder on my hard drive and ran the installer from there. first the installer kept asking for ubuntu cd, but after cancelling this message (which annoyingly popped up several times!!) it finally started installing from the ISO image in the folder. From then on it was smooth sailing!:)
Now im running a windows dual boot system on my laptop with Windows Vista and Ubuntu 9.04. I'm using ubuntu more frequently than vista because i love the way the OS works!,
