My install for OX Lion failed -How do I backup and reinstall

HI,
I am using a Mac Book Pro 3.1
Intel Core 2 Duo
2.2 GHz
# of Processors 1
# of Cores 2

was running with Snow Leopard 10..6

Installed OX S Lion and the computer went to restart and install but cannot
it says the disk is damaged. I tried to repair in disk Utility but failed
It says to save files and folders and do an erase and then reinstall
How do I do a backup. I have not backed up my HD prior to install
Do not use Time machine
I can see my folders in Disk Utility but cannot get to see the burn button

When I start my computer the gray screen comes on and says install Mac OSX to set up click continue.

Help
What Do I do before trying to reinstall
Thanks
Rose

cannot think of doing back up, the main thing is to make your mbp work. If HD fails, it fails, not much you can do. All human made stuff tends to fail.
' the gray screen comes on and says install Mac OSX to set up click continue' may mean your hd is still good ? if not , get yourself a new hd and install the osx see how it works.
Get another hd, to back up your internal drive, this is the route to go.
Sorry to see your old data gone, let this be the last, always back up.

HI yc11688,

My HD has not failed thankfully.
Will try to install snow leopard again and hopefully trust everything will be back on
Thanks for your help

And assume you purchased Lion through the App Store? If so go back in, hold down the Option key and hit Purchases. Lion will come up, double click and download another copy f.o.c. Do not run the installer, but get a USB thumb drive and burn a copy as set out. It will be bootable the same as a DVD:-
