Debian Bookwormにアップグレードしてください。ハードリブートすると grub が起動します。とても良いです。
ただし、デフォルトのグラップ選択を取得するのを待つか、Enterキーを押すと、「ソフトロック - CPU＃0停止」が発生します。
興味深いことに、最初にgrubで「Debian用の詳細オプション」（つまり2番目のメニューオプション）を選択し、Escキーを押して外部メニューに戻り、デフォルト（Debian GNU / Linux）トップレベルメニューオプションを選択してからEnterキーを押すと正常に起動します。できます。特定の詳細オプションを選択して開始することもできます。初期の基本的な定着が可能です。
/boot/grub/grub.cfgを見てみましたが、この問題を引き起こす可能性のあるものは見つかりませんでした（手動で編集していません）。
