Hello, i am currently following an os dev tutorial (https://www.youtube.com/watch?v=7LTB4aL ... a8l0Jb6l8-)

i reached episode 4 and i decided to test my os on real hardware so i used HxD to copy the binary contents of "boot.bin" onto an USB drive and i also made sure that the hex code is placed on the right sectors, the usb drive is MBR formatted (FAT file system). when i boot from it , all i see is a smiley emoji at the bottom of the screen. if you are willing to help me solve this and need more information, you can tell me and i will give it to you, i am not sure what causes the problem and thats why i am saying that

Do not trust OS development tutorials. They're full of bugs.

Did you select the physical disk or the logical disk? Did you overwrite the partition table or leave the one that was already there?

Booting from USB can be tricky. Is your partition marked active?

Source code would help. You might consider using an online version control system like Github - if your hard drive crashes, you'll still have a copy of the code. It's also easier to link to the VCS website instead of pasting your code into forum posts.
