my error = в основном файле сценария /usr/lib/calamares/modules/boot/loader/main.py для задачи python loader произошло исключение. (help pls)
Welcome to the forum 
If I remember this correctly this has something to do with the fact that your efi partition is not big enough, this mostly happens when you are dual booting (and sharing the efi partition) with Windows. Because the uefi patition of windows is not big enough.
hello, i m use 2 more disk windows = C linux = D disk
It would be nice if you could share a bit more information about your system so someone could help you better.
