Hi,
Thanks. I tried that suggestion to no avail. Decided to convert again but first used easybcd to create a clean bcd.
It still BSODs - this is all I tried.......
New conversion, HW version 8, both recovery partition (0) and C: (1) (but not D: and old ubuntu partition) Just Vista in the BCD using easyBCD. Conversion fails with FAILED: Unable to find the system volume, reconfiguration is not possible.
Boot VM > get bootloader error
Boot VM via vista CD > start repair, recovers error
Boot VM > BSOD
recofigure VM > Fails
Boot VM via CD > repairs issues
Boot VM > picks up recovery partition and boots into that via bootldr. No repair possible.
Converter > Fails
Boot VM using recovery Partition > bootrec /fixmbr and bootrec /rebuildbcd - this does not find an installation of Windows even though I have started the boot process several times!!!
Reconfigure > failed
Boot VM > BSOD
Boot using recovery Partition > check registry entries for LSI_SAS as before - set to 0
Boot VM > BSOD
Bit of a loss really 
. Do not understand why the converter cannot find the system volume, but the VM can boot from it (well start to) 
Last converter logs attached.
