Can't load Ubuntu: Superblock checksum does not match superblock while trying to open /dev/sda7

I have a problem while loading into Ubuntu 17.04. This happens for the 2nd time after I booted into Windows. For the 1st time I just reinstalled the Ubuntu. I am not good at this question, so I hope to get a full list of steps to diagnose and resolve this issue. As a workaround e2fsck -b has been used. Here is the output of fdisk -l and it is seems fine to me: Disk /dev/sda: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: gpt Disk identifier: F3EBBDD3-ABDB-4AD4-BBFB-9F97E38D2A2B Device Start End Sectors Size Type /dev/sda1 2048 2050047 2048000 1000M Windows recovery environment /dev/sda2 2050048 2582527 532480 260M EFI System /dev/sda3 2582528 4630527 2048000 1000M Lenovo boot partition /dev/sda4 4630528 4892671 262144 128M Microsoft reserved /dev/sda5 4892672 1029873663 1024980992 488.8G Microsoft basic data /dev/sda6 1029873664 1541873663 512000000 244.1G Microsoft basic data /dev/sda7 1541873664 1737185279 195311616 93.1G Linux filesystem /dev/sda8 1737185280 1741185023 3999744 1.9G Linux swap /dev/sda9 1741185024 1953523711 212338688 101.3G Linux filesystem
