Hi all, I'm trying to upgrade a Dell Inspiron 5000e laptop with CentOS 4.4 installed. When dependencies is checked I receive error "Cannot unmount CD /mnt/sources...". I have CD media and I have tried both text and graphical installer. Anyone have a clue ? Maybe the spec for this laptop is to weak and I must stick with my 4.4 installation... 700Mhz 512Mb ram. When I use the graphical installer, the X server starts but does not display correctly. It is possible to use but you have to guess what and where to click sometimes. Jens
