I've got a sneaky suspicion on that T440 machine that it may be expecting to boot via UEFI, and you've now installed a Debian system that's booting in BIOS mode. If the system's firmware (aka BIOS) is configured to look for BIOS boot first, that would explain why it's no longer seeing the Windows install. What happens if you go into the firmware setup? Can you change the boot options to try UEFI first, or UEFI only? -- Steve McIntyre, Cambridge, UK. st...@einval.com Who needs computer imagery when you've got Brian Blessed?
