Bootload Atmega8 UNO

Can I bootload Atmega8 UNO with Atmega328 UNO bootloader.

I’m very new to micro-controllers. Where I can learn about bootloading of Arduino chips. There are many videos in youtube. I don’t know which one is right.

No. Bootloader is a program placed in a part of flash memory. It is like normal program and it means that his functionality depends on parameters as MCU type, frequency... You have to use appropriate bootloader for ATmaga8. It is good to read MCU's datasheet. Bootloading problem is written quite comprehensible (and very similar for each ATmega), but I'm not sure if it is for full beginner.

Thank you Budvar10.
