error coming up when flashing boot loader to nano when using a uno as an isp

i'm having problems flashing a bootloader to a arduino nano clone using my arduino uno clone to flash.It can't have anything to do with my uno clone because i just used it to flash my other arduino uno clone.

here is the error message:

This report would have more information with

option enabled in File -> Preferences.

Did you forget to disable autoreset on the Uno acting as programmer (by connecting a ~10uf cap between reset and ground on the programmer)?

why do you need to disable autoreset what does it do?and how many volts does the cap need to be?

If you don't disable autoreset, when avrdude opens the connection to talk to the Arduino as ISP sketch, it will reset the board, so avrdude will instead be talking to the bootloader on the one being used as programmer - which runs at a different speed. You must disable autoreset when using Arduino as ISP - the usual way to do this is a 10uF cap (any value around there will work) between reset and ground on the arduino being used as the programmer after uploading arduino as ISP to it.

k thanks will try and see how it turns out
