After cleaning my garage out I found my old PC. I cleaned it off and everything, plugged it in and what do you know.. I had Ubuntu installed on it.. I forgot my password and everything, and I tried going to the recovery menu then editing the kernel or whatever but on the recovery screen when I try to scroll down I get a bunch of red error messages..Anyways... I don't really want Ubuntu on the machine. I want Xubuntu.. I was wondering if there was a way to delete Ubuntu so I can install Xubuntu. Because if I try installing Xubuntu I get to the installation screen but I don't want to go on if Ubuntu is on there..

Thanks guys.

Yes you can, your HDD will be formatted automatically when you install Xubuntu if you choose to use the entire disk.

No it won't work I get this after it loads: http://i.imgur.com/kmTBe.jpg

Hi AcidRa1n.
I was curious on how you got that. Did you download the latest version of Xubuntu? Currently the version should be Xubuntu 12.04.
I believe once you download the latest ISO you just need to burn it on a CD and put it on the computers tray and reboot.
Then the system should walk you throught the installation process with questions about time zone and user log in stuff.
Good luck to you.

My guess would be that the CD you booted to is faulty. Check the MD5 on the downloaded *.iso to make sure that you have a valid *.iso, then burn to a new disk, making sure to use the "burn image" tool (not the "create data CD" tool) of your burning program.

No this is the oldest version of Xubuntu which I actually want. Very lightweight. Do you really think that could be the problem? And before I push install theres a check CD for errors and that was ok.

being an older version, yes it is a problem because it means you will not be receiving security updates etc. it is recommended to use the latest version. if you still think its not light enough for your liking. try a different distro, which is know to be lighter. since you familiar with buntu, maybe debian stable will be a good option since you don't seem to be bothered by older software and it has some things in common with buntu. debian is also longer supported. I think you will be very happy with debian.

Thanks guys I just went ahead an installed Ubuntu 10.. I'm not that worried about updates/security becuase I'm only going to be using it for coding and other offline stuff.

Just to quick mention that Lubuntu is actually lighter than Xubuntu, and your computer will probably run the latest version which is 12.04 as well.
Good luck to you.
