I installed KDE Neon aside with win 10, but during startup the win 10 is selected and I can not any menu to fi change to KDE Neon. How can this be fixed ?

Thanks

Change your boot order in the BIOS to put neon as the first choice there.

On other PC I am running I do get a meny where I fi can choose between win 10 or debian. I think it is strange when KDE neon installation do not make such a meny for startup.

The menu will probably be there, assuming the installation was fully successful.
Normally, a Linux install does change your BIOS boot order, but it also occaisionally doesn't work or fails to happen for whatever reason. At least this has been my experience over the years.
Check your boot order in the BIOS, change the boot order preference, and you should then see the menu.

Case closed, installation of Ubuntu beside it made everything work. Probably a better grub i Ubuntu.
