In this case, could you make/upload RWE reports and backup of the BIOS from both PC - with Win7 and with DOS pre-installed, please?
yes I can but now only for the Win7 PC, How can I backup the BIOS that currently installed on the PC ?
create backup.bat (in the folder with AFUWIN.exe) with next content: AFUWIN /O run this bat file as Administrator (right mouse click and select "as Administrator" )
When you will have access to the computer with DOS pre-installed? (I have an idea how to add a marker, but it needs to be checked)
