Hi Kyle
Sorry for the long delay coming back to you about my issues.
I tried the recovery process agian from the factory Restore Disks, this time skipping disk 4. unfortunately this did not work and I am again getting the same error message, as previously described, in the 'CTOERROR.flg' dialogue box when I select the "Details" button in the Recovery Manager window.
I have found other references to this error message in this forum but none that appear to relate to Win 8. Some of the solutions provided involved hitting F10 and going to the BIOS and reset. Have tried this but F keys donot respond at all on startup.
Any further assistance appreciated.
Regards
GazzaT
