WindowsがGrubメニューにありませんか?

この質問にはすでに回答があります :デュアルブート後、GrubはWindows8オプションを表示しません

コンピューターの電源を入れると、GRUBが表示され、Ubuntuを起動できます。しかし、GRUBに表示されないため、Windowsを起動できません。

boot-repairとsudo update-grubの両方を試しました 無駄に。 BIOSがUEFIを使用して起動を管理していることはおそらく言及する価値があります。

Ubuntu12.10とWindows7を同じドライブのどこかにインストールしています。

/ dev / sdbにMBRがあるのはなぜですか?

これはbootinfoscriptの出力です:

sudo update-grubを実行するだけです およびsudo update-initramfs -u
そしてそれを行う必要があります。
Windowsが/dev/sda1にある場合 sudo update-grub コマンドには、Windows 7 (loader) auf /dev/sda1 gefundenが含まれている必要があります (ドイツ語のローカリゼーション)
