ubuntu 無法啟動 - Linux

更新之後就無法啟動

啟動出現像修復模式的選項

隨便選一個之後出現以下訊息

mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting / sys/ on root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or dirctory

照著

的教學均產生以下訊息

fsck.ext4: Device or resource busy while trying to open /dev/sda1

請問接下來該.....???
