Can anyone explain that many Live CDs do not work on my laptop. All the recent Chip/Digit ones I mean. Linspire (Digit May), ArkLinux (Chip DVD May), Vector Linux, they all boot and I get a Grub prompt grub> with some options with tabs as is the general way with terminal. But nothing beyond. The laptop is Fujitsu Siemens Amilo 7620, AMD 2500+M.
