The problem is, that when I download the ISO and burn it to a CD disc it wount boot up from the CD. Startup is configured to boot from CD. CD gives the install screen what starts to loop. I think it is a server problem.

Did you check the md5sum for the iso image before burning to disk? Since you get the install screen, I believe you properly burned the disk from an iso image (not as a data disk). I often hear of issues resulting from burning a CD at the rated speed. It is best to burn a disk at a slower speed to reduce the possibility of a corrupted burn. Unless I misunderstand their methodology you have an installation disk. The basic distribution should be installed from the CD, so there should be no reason to suspect a "server problem". If the size of the iso image from which you burned the disk is about 700 MB (a full disk), this is the case. If the image size is less than 100 MB, you may have an ftp based installer (unlikely). I suggest you first check the md5sum for the iso image file. Google "md5sum" to find a suitable Windows (or DOS) based utility. The executable should be named something like "md5sum.exe" or perhaps "winmd5sum.exe". You can get the md5sum information file from the location where you downloaded the iso image file. If the resulting value from running the md5sum utility against the iso image file matches the information you went back to get, then try burning the image to another disk at a slower speed (about half the rated speed of either the disk or your burner - whichever is slowest).

check md5 as above. Some hardware might need a boot time switch. Might search for exactly that on ubuntu sites. Some cd drives are odd. Some older CD drives are very picky with burned cd's. Some may work a bit on track 1. The brand of cd sometimes is the issue. Relates to mark space value. There are older computers that can't boot to syslinux, they need isolinux. (or the otherway around) Try the cd on another machine just to see or use qemu or other virtual machine to test. I always boot a downloaded image to a VM. Try a puppy or dsl cd in the older bios choice. "Best Practices", Event viewer, host file, perfmon, are in my top 10
