|---|---|
| `Boot failed: not a bootable disk` | The first 512 bytes of `nadir.img` are not a valid boot sector (they must end with the `0xAA55` signature). Re-run `make` and check it completes without errors. |
| Black screen / blinking cursor | The boot sector only speaks legacy BIOS (`int 0x10` text mode). This works out of the box with QEMU's default SeaBIOS firmware but will not boot under UEFI-only firmware (or UEFI-only real hardware) unless legacy/CSM boot is enabled. |
| QEMU reboots in a loop after `entering protected mode` (or before any C output) | A triple fault in the boot chain: the CPU crashed with no IDT installed and reset itself. Boot with `qemu-system-x86_64 -fda os.img -d int -no-reboot` and read the fault (`v=...`) plus registers from the log. |
