I tried to install ubuntu permanently in my hard disk along side windows 7, but after the 4th step of the installation (http://www.ubuntu.com/download/desktop/install-ubuntu-desktop) the computer restarted without completing the process. I tried 2 times. Do someone know what is that problem or an easy step-by-step alternative?
My computer is a HP laptop (pavilion dm1) with 2 core AMD ALU and 3Mhz of RAM, etc.
I find relevant information in the installation guide:
If you currently have one hard disk with one partition (a common setup for desktop computers), and you want to multi-boot the native operating system and Ubuntu, you will need to:
Back up everything on the computer.
Boot from the native operating system installer media such as CD-ROM or tapes.
Use the native partitioning tools to create native system partition(s). Leave either a place holder partition or free space for Ubuntu.
Install the native operating system on its new partition.
Boot back into the native system to verify everything's OK, and to download the Ubuntu installer boot files.
Boot the Ubuntu installer to continue installing Ubuntu.
So I will try to find information on how to do that if some knows where I can find a step-by-step guide I will be grateful (or any other suggestion)
