[13:34] <Rubenstukken> I installed Ubuntu on a Dell Dimension C521, there is a problem with the mouse, after some search I found out it is a very known problem with Dell C521, which is fixed by updating the Bios. But this needs to be done through MS Dos, So I made an MS Dos Bootable cd, and placed the Biosinstallation file in an ntfs-partition. Problem is, I dont know how to find this partition and hence the installation file when I am booting
