... Read more私も以前、パソコンが起動時にWindows Boot Managerが見つからず、OSが立ち上がらなくなった経験があります。最初は焦りましたが、正しい手順で対処すれば自分でも修復が可能だと実感しました。 特に、Boot Managerが消える原因は様々ですが、BIOS設定の誤りや起動順序の変化、あるいはブート情報の破損が多いです。私の場合は、BIOSでの起動順序を確認し、Windowsインストールメディアから起動してコマンドプロンプトを開きました。そこで、BCD(Boot Configuration Data)やMBR(Master Boot Record)の再構築コマンドを実行したため、問題が解決できました。 しかし、コマンド入力は初心者には難しい場合もあります。そこで私は『Partition Assistant』という専用ツールを試しました。視覚的に分かりやすく、安全に操作できるので、専門知識がなくても起動情報を修復できます。誤った操作で更にトラブルが増すリスクも減らせました。 また、普段からのバックアップやシステム復元ポイントの設定も非常に有効です。トラブル発生前の状態にスムーズに戻せるので、慌てず対応できます。もしWindows Boot Managerが消えた場合は、慌てずに一つずつ手順を確認しながら進めてみてください。PCを元通りに戻し、大事なデータや作業を守ることができますよ。
