终端命令行先输入密码
完后看启动log里面的错误
journalctl -xb

修复命令
fsck /dev/sda2
参考:
My guess for your situation would be that environmental changes have affected you HDD. So from the error message from journalctl -xb which points to file inconsistencies and the instruction to run manual file check. Use the fsck command to correct this error:
fsck /dev/sda2
And simply accept all the options give during the process. Then reboot you system.
