My question would be whether the solus distribution has software where you can perhaps optimize the bootloader? Because if I want to go into Windows, I always need the BIOS... or a command in the console? thank's for the Tipps...
I am assuming that you do not get the usual Linux boot load page when you switch on, and that your computer boots directly to Solis,
so try boot Solis
copy/pate to terminal $ sudo clr-boot-manager set-timeout 5 && sudo clr-boot-manager update
you should [fingers crossed] now get a boot screen giving you the options to chose what to boot, but it won’t be on the screen for very long.
