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 <Magic number> <device> 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 sectorsUnits: sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 4096 bytesI/O size (minimum/optimal): 4096 bytes / 4096 bytesDisklabel type: gptDisk identifier: F3EBBDD3-ABDB-4AD4-BBFB-9F97E38D2A2BDevice          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

I've found solution here 64bit and metadata_csum features should be disabledsudo tune2fs -O ^metadata_csum,^64bit /dev/sdXX
