OK, I am back. Sorry for the delay.
@ Old-Polack : success
I made a remaster as per your instructions, changed permissions and burned it.
Put into the Lenovo and it booted up beautifully , right to the end.
Used it in liveCD mode. All OK
Did not install it, as I didn't see an install icon ( of course not ) and was to lazy to find out

@ debaas
Yesterday I read your post again, and decided that there was no reason why it should not work, one way or another.
Tried again. Instead of choosing thailand ( anything ) I stayed with british
I got then a picture on the left half of the screen.
I needed a magnifying glass , not to read, but decipher the text.
However, I got where I wanted to be and after trying different combinations I suddenly got a full screen. Then I was able to install. After that a little of messing with hardware settings and all was ok
@ menotu
I had to install the pae kernel to get the full 4 Gb available.
@ Ramchu
The Lenovo G470 gets presented/delivered in 6 different combinations,
with 6 very different prices , according to the brochure I have here on my desk.
@ pinoc
Thanks for rattling my brain with German

Really.....thanks

Anyone any questions before I move on ?
