Hi , I recently bought a new Lenovo 320S laptop that is running Windows 10. It has no CD drive. I use Windows 7 on a different laptop and routinely used to make backup system images using the Windows backup tool. This needed the creation of a system repair CD which I would insert into the built in drive and on start up you would have to interrupt Windows to make it boot from the CD drive and then you could make it re-image the disc from a system image backup on an external HDD. I am new to Windows 10 and while I have found the “create system image (Windows 7)” back up option ... and have actually created a system image to an external drive , I would need to be able to make the new laptop boot from a CD drive. It doesn’t have one built in. So would this be impossible to do , even if I get an external CD drive ? When I go to the option to “create a system repair disc” , it says “the system repair disc could not be created , Windows did not find a CD/DVD burner, make sure it is connected to the computer and try again”. But I am doubtful that this would work as a boot option. Don’t the boot options have to be specified in the BIOS ? Sorry I am not very informed about this stuff. So if it not in the BIOS , then it could never be a boot option ? I would be grateful if someone could enlighten me please. Thanks.
