Broken dual boot W10/8

Windows dual boot menu for some reason no longer displayed and W8 boots. The Windows dual boot menu that used to be displayed, listed W10 and W8. The W10 was shown as the default. The OSes are W10 Pro 21H1 and W8.1 Pro. How can I recover the Windows dual boot menu? Any suggestion is appreciated.

 

Dual boot: Problem reinstalling W10

I can see there are many posts here about dual boot systems and various problems that can come up. I haven't been able to find info that seems to fit my particular problem, so I'm posting my question:

I need to reinstall W10 on my dual boot W10/W7 desktop because of problems. The routine I've used before to install W10 isn't working this time:

--With the installation DVD in the DVD drive, and temporarily having boot from disk as the first option in the BIOS, I "click any key" to boot from the disk and the W10 window logo comes up as expected.

But then nothing else happens. The progress spinner that should show up below the logo never comes up. I have to abort.

The above is exactly what I've done twice before to install W10. The spinner has always appeared and then I step through the install process including being able to tell it where I want W10 installed.

Because of this install failure, I tried a different method to see what would happen. Instead of trying to boot from the disk, I clicked to execute the install from the DVD after I had W7 up and running. The expected windows were popping up, user agreement et al. BUT I was afraid to go beyond the screen I'm posting a screenshot of. It's the last window before "install" -- As per the info I've read online I'm thinking that if I click to proceed from there, W10 will install itself on top of my W7 partition without asking me where I want it to install.

Is that correct? Or am I wrong, and it's actually safe to go past this window because the installer will see that this is a multi-partition computer system?

My understanding is that the only way to get the "Where do you want to install?" window is by booting from the disk which gives you completely different installation windows. But, as I said at the top, for some unknown reason that isn't working this time.

Ideas? Is there yet another way to use my disk and reinstall W10 where I want?

add linux dual boot to w10 system

First check to see if Windows supports dual-boot when one of the systems is not Windows. As best as I know it is not possible and I have tried to get the answer myself but that was a few years ago. As best as I know the only option is to use a Linux utility
to do the multi-booting.

If you did configure dual boot then how did you do that? If you are using a Linux/Ubuntu utility then you need to ask in a Linux/Ubuntu forum.

The suggestion to hold down the shift key while doing a shutdown might help but another option is to go into your system's BIOS while booting. The procedure varies depending on the BIOS but if you can get into the BIOS configuration then you can choose where
to boot from. Sometimes it can be a one-time choice but there should be a way to set the boot device priority so that it boots from whichever device/partition you select. That is
not a permanent solution but it will allow you a
slightly inconvenient way to switch where to boot from.

Also note that it is standard for a boot utility to boot whatever partition is marked active. There are Windows and Linux utilities to select which partition will be the boot partition.
