Uups, sorry, I misread your report. Your problem is, you can only boot Windows, and NOT boot Debian. I mixed that up with reports, where a start entry for Windows is missing in the grub menu. In your case, my best guess would be, to start the debian-installer again, but from the installer menu choose the "Rescue" entry, to not perform another installation, but start a recovery environment, where you get the possibility to fix such things. There, mount the corresponding partition (the partition, where you installed Debian on; I guess this might be /dev/sda2) as /root, and then do similar as written above: execute "TERM=bterm nano /etc/default/grub" to make a line containing "GRUB_DISABLE_OS_PROBER=false" in that file Then call "update-grub". Please report, how it goes. Holger -- Holger Wansing <[email protected]> PGP-Fingerprint: 496A C6E8 1442 4B34 8508 3529 59F1 87CA 156E B076
