Sounds like you have a bad picroft image. Remove that one, download a new one, verify the hash values to make sure it’s correct and try again?

can you suggest me an image , i have tried 3 images

What images have you tried so far?

picroft - pork and lightning one

Like what names and links were you trying to use?
Did you verify the hashes matched?
How did you burn them (in explicit detail of all the steps you did)?
The more information you provide the more likely a solution will appear.
