發行版: Lubuntu 19.10
Linux經驗: 低
昨天安裝完系統後在摸索套件的過程中,用套件管理軟體使用了全部更新按鈕
過程還算順利,但在中途跳出一個問題是請問grub要安裝在哪個分割區
我的分割區主要就 /、/boot、/home 三個(外加一個SWAP)
查了一下grub是開機用的套件,所以就選了/boot
之後他就繼續更新下去,只是最後跳出一個失敗訊息,但是我沒在意就沒記錄下來
然後我將電腦重開機,結果在跑完BIOS硬體檢測後出現亂碼
說亂碼其實也不是,只是由一堆詞跟數字組成,找不到可以閱讀的句子
只看得懂裡面有kernel這個詞
---
現在我想先用USB來修復grub試試看,想先問問看步驟有沒有問題
照網路上找到的方法:
sudo fdisk -l #查看電腦中的硬碟分割狀態
sudo mount /dev/sda1 /mnt #掛載分區 #這邊比較有疑問,我要掛的是/還是/boot
sudo grub-install –boot-directory=/mnt/boot /dev/sda #修復grub
#這邊的疑問是好像上面直接掛/boot分區的中間是--boot-directory=/mnt
#如果沒有/boot分區的話就是--boot-directory=/mnt/boot
不知道對不對,先感謝幫忙回答的各位先進了
