I installed the MikeOS on a USB-stick to try to boot from it after my own OS i made wouldn't boot. I turned on legacy boot support from the bios settings and then from boot options I choose the USB stick, but then it just said "Insert bootable medium and press any key", it said the same for both mine os and MikeOS. My OS was made following the instructions: http://mikeos.sourceforge.net/write-your-own-os.html . Later when I used the dd command to write the os.flp straight to a USB stick witch had a FAT32 filesystem it just booted into a black screen with a blinking white text-cursor. Does anyone know how I can fix this? I'm using a HP Envy x360 Convertible 15m-dr0xxx (64bit) Intel core i7 (8th gen).
I had secure boot off from earlier
