We have a lot of computers that have been donated to our school, but they are all running very slow. I am trying to find a way to make the computers run better without costing us an arm and a leg.

Someone suggested I try Ubuntu and I just tried installing it on one of our old computers. I got the following message:

This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot.

Is there an older version that I would be able to install so we can use the computers. I have about 20 computers throughout the school and we have not been able to use very many of them for a few years. We are trying to make them run faster, so we can run some new math and reading software we will be getting in the fall.

    From about 2006 onwards most Intel processors have been 64-bit enabled. Older processors will require you to install the 32-bit version of Ubuntu. (for old computers you might find that Lubuntu runs better on them) – pHeLiOn Jun 01 '16 at 01:14

The message you are receiving means that you are trying to install 64-bit software on a 32-bit system. You have to download the 32-bit version of Ubuntu which can be found over here and this is the .iso you need to download: ubuntu-16.04-desktop-i386.iso.

Since you are about to use Ubuntu on older machines, it would be better if you gave us more information about their hardware and RAM size because Ubuntu is not a very light distro and it's very likely that you may need a lighter one.
