之前發生在更新Kali Linux後，同台電腦多重開機的Windows選項居然不見了的事！只好上網找資料解決。其實解法也不難，只是還要找很討厭。為什麼Kali Linux系統更新後，不能自己執行更新GRUB的指令呢？
(一)修改開機OS選項：
1.執行sudo leafpad(Ubuntu下改成nano) /etc/default/grub。
2.接著修改GRUB_DEFAULT=0的參數值，看看欲開機的OS在選單順序為何？(如果沒出現，可先執行一次sudo update-grub指令)即設該值(注意是0 base)。
3.存檔後記得執行sudo update-grub。
(二)系統更新後原多重開機選單不見：
1.執行sudo update-grub即可。
回覆刪除請問前輩:
我在我的surface pro 電腦上安裝kali系統
從網路上找的grub
做更改
但是還是無法成功的安裝
可以請前輩幫忙看一下
是否在那邊出錯了
以下是grub 更改細節
