My current grub is
menuentry “OSv” {
multiboot /boots/service/release.x64/vmlinuz.bin
boot
}
This returns “no multiboot header found. You need to load the kernel first”
Also, I don’t need any networking capabilities. Just trying to run a simple
program and show it can boot bare metal :)
Think of it as me trying to run the “native-example” app that prints out “Hello”
Also, thanks for all the replies and help!!
