View Full Version : [ubuntu] Reinstall newer version of Ubuntu on an existing partition

August 9th, 2012, 05:21 AM
Greetings !

I started with a Windows 7 machine and wanted to have Ubuntu as well.
I used the "Install Side by Side" option to install 9.10. So I had a dual boot system (ubuntu 9.10 and Windows 7) with Grub Loader.

After this point, I got a "black screen" when I boot into ubuntu, because of the display driver incompatibility, specific to my laptop (lenovo g550).

I did not bother to fix the issue, because I had to get going. I used Wubi to install 9.04 inside windows, which worked well.

Now I want to upgrade my ubuntu to 10.04. I want to do a fresh install of 10.04 over the 9.10 (which is not working).

How can I do this ? I want to do this without losing anything on any of the partitions (windows 7 or Ubuntu 9.04) except the one on which the 9.10 is installed.

Thanks for any help.

Welcome to the forums.

You will need to use manual install or something else. It will give you the option to choose which partitions to use for what / (root), /home and it swap exists it should automatically find it. You also have to specify format usually ext4 for / and /home if you have it. If you have /home but want to save the data DO NOT check format on /home.

You also can from liveCD use gparted and just delete the / & swap partitions and then let is install side by side to the unallocated space.
