So I know this has been asked alot on this site, but I want to be a 100% sure if I am doing it correct (seeing as I don't want to break my notebook or what not).

I read several questions and I think I figured out how to do it, (please note I only have 32 bit for a day, so I don't have to be afraid of losing files):

  1. First I go to

  2. Once there I'll download the 64 bit version.

  3. I restart my computer and dual-boot to the 64-bit version.

  4. Once I am in the 64-bit version I perform steps 3 to 5 of this question.

Am I correct? Or will my laptop fall apart if I attempt this?

I did the test described here, and yes my notebook is 64-bit compatible.

I am totally new with Ubuntu so please be gentle :)

You don't really have to uninstall the previous 32 bit version of your Ubuntu. Download the 64 bit image and install it on the same partition where you installed the 32 bit version. That should do it. I followed the same approach when I installed 12.10 on my Desktop and I dint screw it up! And don't forget to format the EXT4 partition so that remnants of 32 bit is completely wiped out.

I see you're totally right! By the way I also found out that once you start wubi.exe he automatically asks if you want to remove the version already installed :D Now my notebook is monoboot again! I just have to make a bootable usb for now :) thank you! – Jordy Jul 10 '13 at 12:50
