A few questions:

Does your computer support BIOS, UEFI or both?
Did you used graphics or only text mode (console) in your OS?
In case you used graphics, have you choosed VBECanvas, VGACanvas or SVGAIICanvas?
Are you using userkit or devkit?

Answer 2 · 2024-09-17T23:27:52.000Z

My computer supports UEFI, I’m using the console mode and I’m using dev kit

Answer 3 · 2024-09-17T23:51:47.000Z

But you are booting in legacy mode?

Answer 4 · 2024-09-18T00:00:25.000Z

Does it boot on a vm?

Answer 5 · 2024-09-18T00:32:54.000Z

Oh btw I did use SVGAIICanvas but I’m just using console rn. Also what graphics work with real hardware?

Answer 6 · 2024-09-18T02:08:19.000Z

only VBECanvas works on real hardware iirc

Answer 7 · 2024-09-18T02:47:05.000Z

So how do I make it work and boot on real hardware?

Answer 8 · 2024-09-18T02:57:26.000Z

Try with cosmos default OS and see if it works, if not then i think we'll need your code, at least the start of it

Answer 9 · 2024-09-18T03:07:50.000Z

I made no changes to the code it’s the default console

Answer 10 · 2024-09-18T04:03:21.000Z

Are you using rufus, ventoy or another tool to burn the ISO?

Answer 11 · 2024-09-18T05:08:46.000Z

remember that vga doesn't work with uefi (aand vga text mode)

Answer 12 · 2024-09-18T12:10:27.000Z

I’m using Rufus 2.18

Answer 13 · 2024-09-18T16:55:18.000Z

this happens to me too, only boots on real hardware if using the userkit

Answer 14 · 2024-09-18T17:14:26.000Z

But how do I use the vbecanvas?

Answer 15 · 2024-09-18T17:16:08.000Z

Fr?

yeah, but userkit is very outdated compared to the devkit so its not really a good idea to use it

Answer 16 · 2024-09-18T17:22:24.000Z

I tried it with the user kit and it didn’t boot

Answer 17 · 2024-09-18T20:31:44.000Z

im not sure if there are any differences here, but ig you could try the ISO mode in rufus and if that dosen't work then try DD mode

Answer 18 · 2024-09-18T20:40:52.000Z

Ok I’ll try later I’ll let you know if works

Answer 19 · 2024-09-18T21:09:37.000Z

If you have any other hardware you can try, it might help to rule out whether it's your kernel or the hardware. Even better, (but unlikely), if there's a way to get serial output out of your laptop you could access the debugger potentially (think that's how it works)
