重啟電腦並使用Fedora的LiveCD（安裝光碟）開機
點try fedora後打開終端，輸入並執行
# lvm
lvm> vgchange -a y
lvm> exit

sudo fsck -y /dev/mapper/fedora-root
然後重啟電腦

重啟電腦後（記得拔出livecd安裝光碟），會發現Emergency Mode螢幕已經消失，可以直接進入系統了。
本解決方案適合那些安裝Fedora時選擇了清空整個硬碟的安裝方法的人。
此時根分區是綁定在/dev/mapper/fedora-root這個設備上的

sudo lvm

非lvm分區（也就是standard標準分區）的修復方法：（以 /dev/sda11為例）
sudo fsck /dev/sda11
（注意此時不可以掛載該分區）

[liveuser@localhost ~]$ sudo fsck /dev/sda11
fsck from util-linux 2.26.2
e2fsck 1.42.12 (29-Aug-2014)
/dev/sda11: clean, 27085/3186688 files, 390415/12723712 blocks
執行後如果顯示這個，則說明分區正常。這個命令也就白運行了，沒有起到作用


[liveuser@localhost ~]$ sudo fsck /dev/mapper/fedora-root
fsck from util-linux 2.23.1
e2fsck 1.42.7 (21-Jan-2013)
/dev/mapper/fedora-root contains a file system with errors, check forced.

如果顯示這麼一長串，那麼該分區有錯誤。
