Exactly that is the point, GRUB does not detect any OS on this partition and I'm told that the file system is not valid (After shrinking only the file system and not yet the partition, I was able to boot into Windows). I believe there is a problem with the partition. It starts at sector 2048 (That's what fdisk set it to when creating a new partition, no smaller value possible via this tool). I installed several GRUBs (GRUB legacy & GRUB 2), they all failed to recognize Windows.
Does anyone know of a Linux partitioning tool where you can set the beginning of a new partition at sector 64? That's the starting point of a NTFS-formatted USB drive, and I suspect, that is where the Windows partition should actually start for GRUB to detect a Windows operating system.
In the meantime, I guess I will install Windows 7 on another computer
Thanks for your help,
