私はかなり長い間Debian（Acerノートブック）を使用してきましたが、多くの問題は発生しませんでした。しかし、最近使用を開始したときに、次のようなメッセージを受け取りました。
No bootable device - insert boot disk and press any key
ライブCD（xubuntu）と連携し、ハードドライブが表示されます（ライブCDからいくつかのバックアップを作成できます）。
インターネットを検索した後、BIOS AHCIモードをIDEモードに切り替えました。動作しますが、パフォーマンスがはるかに低く、ブラウザを開いてファイルをコピーすると入力/出力エラーが発生し、ハードリセットを実行する必要があります。
ハードドライブが破損しているか、システムに問題がありますか？
たぶん役に立ちます：

一般に、Live CDは、システムのすべての機能を使用せずに自給自足が可能なソフトウェアパッケージであるため、よりうまく機能します。
まず、ブート時間パラメータを使用してacpiをオフにしてからdsdtを確認します。
