grub-install：錯誤：找不到 EFI 目錄。（重新安裝 Grub Boot Loader Windows 10/Kali Linux Dual Boot with Dual Hard Drive）
我的筆記型電腦中有 2 個硬碟驅動器 (SSD)。一個硬碟安裝了windows 10，另一個硬碟安裝了kali linux。重新安裝 Windows 10 後，我的 kali linux grub 引導載入程序不再工作。因此，我嘗試使用 kali live cd 重新安裝 kali linux 的 grub 引導載入程序。
我使用這些命令為 kali linux 安裝 grub 引導載入程序：
sudo mount /dev/sdb4 /mnt sudo mount --bind /dev /mnt/dev && sudo mount --bind /dev/pts /mnt/dev/pts && sudo mount --bind /proc /mnt/proc && sudo mount --bind /sys /mnt/sys sudo chroot /mnt grub-install /dev/sdb每當我寫命令時：
grub-install /dev/sdb我收到一條錯誤消息“ grub-install：錯誤：找不到 EFI 目錄。 ”
誰能幫幫我！
這是 fdisk -l 結果：

這種類型的問題在 Windows 10 中很常見。它有重新格式化 EFI 分區的習慣。
Grub-install for EFI 將文件安裝到 EFI 文件系統。首先為自己掛載文件系統還不夠智能。它期望 EFI 分區已經掛載到
/boot/efi.使用 .找到您的 EFI 分區
blkid。它應該是一個 0.5GB 或更小的 vfat 文件系統。然後將它掛載到 /boot/efi 並檢查你現在有一個目錄 /boot/efi/EFI這將讓你執行
grub-install根據您的螢幕截圖，這意味著您需要：
sudo mount /dev/sda2 /boot/efi sudo grub-install
