If you can, try deleting all the partitions and re-create them using GPT instead of DOS (MBR) and see if it then shows the same. Also agree that you should make your boot partition 1G.
Linux
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What does /proc/partitions say?
Also, if you plan to use that 256MB partition for /boot, make it bigger. I go for 1G lately.
same as lsblk
thank you for advice.
Try running partprobe.
partprobe says:
Warning: The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes.
Block size? I’ve never seen that message before and I don’t think it’s relevant here. It should redetect the partitions to what they actually are though, but I assume it doesn’t for you.
Also, are you sure you want MBR on that disk instead of GPT? (At least, I think that’s what “Label: dos” means)
Actually, I don't really know differences between. Just all guides use cfdisk and I forgot about mbr and gpt. But I changed mbr to gpt using gdisk(after start he say, that I have mbr and gpt and which I want to use. I chose "create blank gpt" and now I can use gdisk to partition disk. And after gdisk lsblk show right information! Thats it
Nice! Pretty sure cfdisk also can create a new partitioning scheme but I don’t know how right now
