I have just formatted everything off my pc and reinstalled windows and LFS , i try to start it but it sais could not detect any suitable screen modes? , any ideas of how to fix this ...
Can you get us a screenshot? (press Print Screen on your keyboard, paste into word and save as a gif or jpg), and then attach to a post (you must be in advanced posting view for attachments).
It sounds like you've got a screwed shortcut from your comment, but a picture can be worth a 1000 words..
