Yes, exactly. It works as it should: Upon boot the GRUB menu is presented,
with Debian, its emergency option, and the option of booting into Windows.
Thus, all is right in the world. :-)
That was done by disabling secure boot in the BIOS and running the
"bcedit /set {bootmgr} path \EFI\debian\grubx64.efi"
command as administrator in a Windows shell/command prompt.

You might want to look through pages like: https://wiki.archlinux.org/title/Dual_boot_with_Windows https://unix.stackexchange.com/questions/524622/what-is-the-relation-between-uefi-and-grub just to get an idea of the issues involved. Then, when you boot into Windows and linux, you'll be aware of where to look for diagnostic information on the problem. If there are better starting points than those references, I'm sure people will post them here. Lastly, it might help to post how you booted the Debian installer, and what choices you made when installing Grub during the installation. Cheers, David.

When I discussed my Windows 10 PRO purchase with them, the earlier part of the conversation was, before I had selected PRO over Home and the person on the phone did not bring up anything about Home on Virtual environments. So my suspicion is that it will, at least technically run in a Virtual environment. Good luck! Kenneth Parker >

What you need to do is to get grub in the right place and have it configure the boot menu for itself to be given first boot. Did you use the Expert installer? I put stretch on a Win10 netbook, at some point the installer said it had found another OS, did I want dual-boot? I didn't actually need Windows, but I said 'yes' to keep the option open, and stretch just did it. No problem. The BIOS was UEFI and didn't have a secure boot disable, but it still just worked. Mind you, when I upgraded to buster, I could no longer boot the machine at all without manual use of the BIOS boot menu, so I consider buster's installer inferior to that of stretch. Haven't tried bullseye yet. And bear in mind that some BIOSes are broken, and do not implement UEFI correctly. Mine fortunately honours NextBoot, or I really would have to eliminate Windows, but frustratingly does not honour DefaultBoot, and always defaults to a state where it looks for Debian but fails to find it. If Debian is NextBoot, it is found with no difficulty, so it's not that the UEFI boot code is in the wrong place or is non-functional. -- Joe
Debian 11 and Win10 dual boot
On a new HP Laptop pre-installed with Win10 Home edition installed on an SSD. In the laptop's BIOS Secure Boot was turned off. A fresh copy of Debian 11 was installed into the machine's 1TB HD. After reboot, GRUB comes up normally and Linux works fine. But once Windows is chosen from GRUB Windows overwrites the MBR and on subsequent boots GRUB has been disappeared and the machine boots straight into Windows every time. Question: How can Windows be lobotomized to stop it from overwriting the MBR and doing this behavior? -- "Every gun that is made, every warship launched, every rocket fired signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed." -- 5 star General and US President Dwight D.
