Hello,
I tried everything I know to install a bootloader in a lot of atmega328-pu chip I have, but I always had errors, in Arduino IDE and with the command line of avrdude... the signature of the diveces are 0x010305. My programmer is a AVRISPMKII.
Anyone can help me please... Tkx.
So please describe what you tried and how it's connected 
The ATmega328 (non p) isn't originally supported by the IDE. That's because the ATmega328 and the ATmega328p have different device signatures. If you want to use the ATmega328 with Arduino IDE, you'll have to install MiniCore, which have support for the non p version, as well as the rest of the family. simply select the correct versions in the variants menu.
I'm using the Arduino board and the AVRISPMKII to program the bootlader... since it have the crystal ans the suplly to the chip.
With avrdude I get this error:
