I read the tutorials to make a mimalistic custom kernel from here and am able to boot it up as explained in the tutorial over a virtual machine using GRUB as the boot loader.I think it would be more fun if I could do the same over bare hardware using a bootable pendrive. That is use GRUB, pendrive and my Kernel executable to form a bootable pendrive and then boot into the kernel from this pendrive.Q1. I thought of using the normal procedure of how I make a bootable linux pendrive, but my kernel isn't really an iso image, its an elf format executable. Will the normal method work if I somehow convert my executable to iso format ?Q2. Any other ideas / link to some resource how I should proceed ?P.S. : Its NOT Linux kernel per-se, Its absolutely minimal kernel, no file system nothing. Just boots up, prints something on console and can handle keyboard events, thats it.
