foshizz :
When i use Ubuntu in virtualbox, my live cd is able to boot fine. When I try to use my live cd on its own, my system seems to always crash. I use all the boot parameters and yet it still seems to fail. Any suggestions?
What do you mean 'crash'? is there any messages?
Post your hardware configuration.
Also please make sure the md5sum matches the one listed on ubuntu website.
Also check that the cd integrity is fine after burning (ie the md5sums still matches)
You can't just say 'it doesn't work' and expect anyone to magically know what the issue is!
