If you have two linux installs and one windows
Lets say Debian is the normal bootdevice and we are booted into it.
We then bootnext into Windows.
We then bootnext into Arch - but we will end up in Debian due to the bootnext sets BootNext for Windows bootmgr and not the systems.
The only way to have this work is to have Windows be the default instead of Debian, and then have Debian the default in the windows bootloader.
Hope it makes sense
