目前，我在 hp15r204tx 笔记本电脑上使用双启动的 ubuntu 16.04 LTS 和 windows 8.1，运行良好。但突然间 grub 在启动很长时间后才出现，当我移动箭头键选择任何选项时，grub 菜单非常滞后且响应缓慢。我的 etc/fstab 文件如下所示
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda11 during installation
UUID=dbfa8dc7-3265-4f19-85ef-584294eed2fe / ext4 errors=remount-ro 0 1
# /boot/efi was on /dev/sda2 during installation
UUID=207F-463D /boot/efi vfat umask=0077 0 1
# swap was on /dev/sda10 during installation
#UUID=070ab5c2-2c28-4e86-baae-3d3900bfeeac none swap sw 0 0
这是 systemd-analyze blame 的输出
