我更新了 Ubuntu，重新啟動後出現以下錯誤畫面：
到目前為止我嘗試過的事情：
- 從 USB 上的 Ubuntu Live 啟動修復；不用找了;啟動到各種恢復模式也沒幫助。
- Memtest大約90分鐘，沒有發現錯誤。
- 完全更換 RAM；仍然沒有差別。
我並不害怕命令行，但我對 Ubuntu 沒有深入的了解。

答案1
由於您無法啟動進入復原模式，因此fsck您的檔案系統...
- 引導至 Ubuntu Live DVD/USB
- 打開一扇
terminal窗戶 - 類型
sudo fdisk -l - 識別「Linux 檔案系統」的 /dev/XXXX 裝置名稱
- 輸入
sudo fsck -f /dev/XXXX# 將 XXXX 替換為您之前找到的號碼 - 如果有錯誤，請重複 fsck 指令
- 類型
reboot
更新#1：
- /dev/sda2 上的 fsck 沒問題
- 電腦同時具有 -48 和 -50 內核，無法從任一內核啟動
- 我們將 initrd.img 檔案更新為 -50，沒有幫助
- -48 核心的 initrd.img 是從 5 月 18 日開始的，所以它應該可以啟動
- -rw-r--r-- 1 root root 38477701 5月18日10:37 initrd.img-4.15.0-48-generic
- 兩個選擇：
- BIOS從2011年的A05更新到2017年的A20
- 備份重要的 Ubuntu 檔案並重新安裝 Ubuntu
更新#2：
- BIOS 更新至 A20 並沒有解決問題
更新#3：
- Ubuntu 已重新安裝
- 但是它安裝了錯誤版本的 GRUB，並且無法啟動
boot-repair透過安裝正確版本的 GRUB 解決了問題- 使用者應該檢查BIOS設定是否為UEFI，然後擦除磁碟，並重新安裝Ubuntu
