Now the first thing was trying to get past the “BSOD” by booting into safe mode and then trying the various options , last known good configuration etc.
None of this worked.
This is when I booted from my Ubuntu disc.
Ubuntu will give you the option of having a look without altering your current Windows installation and that is the option you want , not the install option which will wipe your hard drive.
Let the installation run and in a few minutes it will look like a new desktop but you should have access to your files.you will see the hard drive symbol appear on the left hand side of the screen.
You can then back them up to a portable hard drive , flash drive etc.
There is also an option to repair the disc which I did and then reboot the system to see if Windows will run.
In this case it did and once again emphasizes the need to back up on a regular basis.
