(FIXED not Solved) Grub will not find win installation after new install

[melmarker]

that means that windows will only be found _and_ can only start in legacy mode - so i would suggest to switch to "legacy first" and modify the system that way

Yes, I did change to only UEFI just to test. But can it not be "Both" as it has been before?

the problem is that the stick with that you can fix the installation must be started in legacy mode - and that means that you will run both linux and windows in legacy

So would this be a solution?

Boot with a linux-usb stick that boots in legacy mode. Checkroot in to my installed siduction and reinstall Grub?

I have fixed the issue ie, it's not solved really. Couldn't find a solution to start legacy win from uefi grub.

I did a new win install with win  uefi.

Then win allways started first and I had to use "f12" to start grub and siduction, the option in bios to choose boot order is gone.  After update-grub , grub found my win install but win started anyway first on boot.

I tried to reinstall grub on siduction disc and yes now grub is starting when starting computer and I can use it as I want, multoboot with grub.

You solved your problem, not only fixed it. There is no way to use uefi and legay os the same time with the same setting in bios/uefi.
