I've tried using this method, but i'm not sure which syslinux.cfg to copy over and rename to kaspersky.cfg. I'm assuming there is one on the Kaspersky Rescue Disk but i cant find it. I'm using the CD version as it looks like it's the same as the USB one because you have to create the USB one with a utility using the CD image.
I've also tried copying the syslinux from the boot\syslinux folder but obviously that just restarts the menu. Any help? I think i've got everything else copied over properly.
Typically, you must make the Kaspersky Rescue Disk as a USB using their utility first.
This will not only affect the syslinux.cfg file you need (which should be located in the root directory of the KRD USB), but will also affect the files in the Rescue folder. Basically, the USB version of KRD is required.
