Package: installation-reports squeeze / amd64 fresh install on a Thinkpad X61s Windows 7 is already on the machineThe installer told me it found Vista and asked if I want to install grub to the MBR. I agreed to install MBR.
On rebooting, the grub menu appears and Debian is the only option.Checking the partition table with fdisk, I can see that Win 7 is still there.
