I was having problems booting linux mint live cd with my computer and I solved it using boot parameters. I found two solutions:
how to add boot parameters: https://help.ubuntu.com/community/BootParameters
(parameters must be added just before "--")
solution 1 (best): use the parameter "nomodeset"
solution 2: use "noapic" and "acpi=off" together but the the os does not shutdown correctly.
I hope it will help people.
