@onkar
40_custom entries were in a single line.It was the problem while pasting
into gmail
It should be in a single line as you said.


It Worked!
I did not modify anything .Itt seems that lucid is not friendly with my
hardware --so it hangs.


However you cannot install to the hard-disk in which your ISO is located as
all the partitions were required to be unmounted during installation.

I have installed lucid but now it hangs at the GDM login screen ( same as it
did when i first booted from iso) ,will collect more details and will send a
new mail if help is needed.

Thanks
