Hi! I am making a OS in C using GRUB as mt boot-loader and an asm file to boot the kernel which is in C everything compiles fine and when I boot it goes to GRUB mutiboot as it should, then I click on my kernel, but the screen goes black with just the cursor and hangs for a few seconds then reboots??? do you know what could cause this?

Required Knowledge, Asking Good Questions - You should know these.

Have you tried in an emulator? Have you checked if your kernel even starts to execute? (make a stub that just prints to the screen and then locks)

Triple Fault could cause this. Relevant portion of code required.
