It looks like you erased the Windows bootloader when installing Linux.
You can send a screenshot from GParted?

[gosts 87]

I do not see your mount points. They need to be assigned during installation. And I do not see the designation of the ext4 file system

I wrote above. Can't see mount points. I also don't see the boot section.

Due to the very long name of your first section, all sections of the GParned are not visible ... The most important thing is just on the right side of the screen (GParted).
