I might have come to an invalid conclusion from reading the changelog snippet quoted earlier and then went to lay far too much emphasis on Jessie d-i preceding Windows 10. What is fixed is not whether an entry for Windows 10 is displayed but the wording of the entry in the GRUB menu. Apologies for anything misleading. > It does seem curious that the Debian installer would need knowledge of a > particular Windows version in order to provide a boot menu selection for it, > rather than simply having one that says "Windows", booting from whatever > non-native/NTFS filesystem it happens to find containing anything resembling > boot sector code. Yes it does appear curious, especially as the implication in the changelog (and a few reports I've seen elsewhere) is that a Windows 10 install can be discovered by os-prober but provides "Windows Recovery Partition" as GRUB's menu entry. > Should you be game to try installing Jessie again, you might try a network > installation started via a Stretch installer.

Another possibilty is https://wiki.debian.org/DualBoot/Windows10
