I have approx 32 years experience with computers and it has taken me about that number of hours to successfully install Ubuntu 12.10 as a dual boot system on Windows 7 machine.
A most frustrating experience.
Now I find I cannot boot into Windows 7. The boot partition indicates it has a size of zero.
In my slavish reproduction of scripts to edit 'Grub' and avoid the /cow I have obviously done something but have no idea where to turn to now.
I have a Recovery Disk and obviously an installation disk for Windows but neither help. The 'Repair your computer' just goes into an apparent endless loop and no backup images are detectable anywhere even though I thought they regularly got created.
As an added complication No LH bar of icons appears nor the top toolbar when I log into Ubuntu.
Could this just be an incredible coincidence?
Thanks in anticipation.
