I am pretty sure that I was able to boot the same linux kernel as now and windows on the HD, when using the grub instance which was on another SSD (which is now retired). I guess I can try putting it all back together again to collect values of environment variables in a working setup - will this help? > > > prefix (hd0,gpt3)/boot/grub > > IIUC, (hd0) is the SSD containing the GNU/Linux system root filesystem ; > the EFI partition (hd1,gpt3) containing Windows boot manager is on > another drive (hd1). correct, linux root file system is on the same SSD where grub is, Windows is on the new SSD. > You mentionned that you could reinstall Windows.

Right, I created a gpt partition on the SSD and then installed windows on it, which carved a few small partitions out of it. But the linus root file system is also on a disk with gpt. > Could you provide the previous and current drive/partition layout of > this machine ?
