GRUBを修復できるDebianソフトウェアはありますか？

Question

これはDebianとは何の関係もありません。あなたが経験している問題は、オペレーティングシステムが起動する前に発生します。奇妙なことに、これは時々起こります。

1つの可能性は、ハードドライブにエラーが発生したことです。出力を確認してください

sudo smartctl -a /dev/sda

次の行が表示されます。

SMART overall-health self-assessment test result: PASSED

GRUBが取り付けられていない場合は、正しいデバイスと/dev/sda交換してください。/dev/sda以下をインストールする必要がありますsmartctl。

sudo apt-get install smartmontools

そのため、ドライブからデータを読み取るのに問題があるようです。この問題が最近開始された場合、ドライブが破損している可能性があります。私はあなたをお勧めしますすばやくバックアップして新しいドライブを購入する。

ドライブを交換する前に、ケーブルの接続が正しいことを確認し（HDDケーブル）、他のケーブルを試してみてください。
