I'll give you a list:

1. Standardized mode numbers are deprecated and should not be used.
2. You are calling a real mode interrupt from inside protected mode (GRUB puts you in pmode)
   • If you are using v8086, it should work, but based on your question, I don't think you know how

you a reason I do not know and do not drink how: s
if you could explain it to me would be cool

Self-explanatory
