upgrading to raring ringtail stalled

You can boot to the USB and reinstate the boot loader, you can also continue the upgrade with:

sudo apt-get -f install

Have made a live DVD of 13.04 and hopefully I can boot up with that.
My desktop screen is totally black with a flashing white spot close to the
top left corner.
If I make a new installation can I restore my data using the backup on
Dejadup?
Thanks
John

The desktop boots from the live CD

Reinstalled Ubuntu 13.04 from the live CD and all is well
