Hi Andrew, Matthew and Kevin, Thanks for the replies, it is really appreciated. I have solved the problem and my LFS boots fine.... there is no one more surprised than I. I feel I have really achieved something.
I did not manage to get it to boot on the USB stick, I believe the problem is more to do with this laptop than anything else. I recompiled the kernel 4 times and included every module I could think may even have the slightest to do with it. I did read all the help info and after getting no further forward this is what I did. My laptop HDD was already partitioned into 4 primary partitions... sda1 boot 60MB sda2 swap 500MB sda3 / 15GB sda4 /home 280GB I cleared some space on sda4 and shrunk it. I deleted sda2 and called it a loss. I created 2 extended partitions in the 20GB I recovered from sda4, sda5 became a new 500MB swap and sda6 an empty ext3 drive. I copied everything from the USB stick to sda6 changed the LFS entry in my existing old grub menu.lst and rebooted. Selected LFS and it booted perfectly. Thanks to everyone for their help. As soon as I have finished having a play with it I intend to delete it all and do the LFS install all over again (doing all the tests fully this time). Thanks again Clive.
