私はWindowsとFedora KDEをデュアルブートします。システムの起動時にWindowsブートマネージャを選択すると、次のエラーが表示されます。
error: ../../grub-core/commands/search.c:315:no such device: 7E79-F46D.
error: ../../grub-core/net/net.c:1552:disk 'hd1,gpt1' not found.
Press any key to continue...
Fedoraで直接起動するとFedoraでうまくいきます。
error: ../../grub-core/net/net.c:1552:disk 'hd1,gpt1' not found.
error: ../../grub-core/loader/i386/efi/linux.c:258:you need to load the kernel first

さまざまなディストリビューション（mint、manjaro、pop os）を試しましたが、問題は解決しません。ただし、BIOS起動メニューからWindowsから起動できます。オンラインで読んだ後、Ubuntuブートリカバリを試してみましたが、次のような結果が出ました。

SSDにはWindowsを、HDDにはFedoraをインストールし、100GBのスペースを割り当てました。
クイックスタートが無効になっています。
ブートメニューはブートローダのインストール自体を管理するため、Ubuntuでうまく機能します（少なくとも私の考えではそう思います）。
答え1
sdb1私が見るには、Fedoraがインストールされた後、ある時点でディスクのESPパーティションが再フォーマットされ、それ以降Fedora用のGRUB構成ファイルが更新されていないようです。 ESPのボリュームシリアル番号（FAT32パーティションでファイルシステムUUIDの代わりに使用される番号）が変更され、GRUBはまだ古いシリアル番号を探しています。
Fedoraにos-proberこのパッケージがインストールされている場合は、Fedoraを起動してrootとして次のコマンドを実行すると、変更が簡単になる可能性があります。
grub2-mkconfig > /boot/grub/grub.cfg
os-proberこれにより、Windowsブートマネージャの場所が再検出され、古いFAT32ファイルシステムのシリアル番号7E79-F46Dが新しいシリアル番号（9228-4C98と表示）に置き換えられます。
または/boot/grub/grub.cfgFedoraで手動で編集し、文字7E79-F46D列を9228-4C98。
このメッセージは、見つかった各オペレーティングシステムに複数の「検索のヒント」を追加したdisk 'hd1,gpt1' not foundためです。os-proberしかし、ファームウェアのディスク検出順序を正確に知らないため、パーティションがおそらくsdb1ファームウェアhd1,gpt1用なのでGRUB用であると推測するだけです。
펌웨어가 실제로 드라이브를 다른 순서로 감지하여 os-prober추측이 잘못되었을 수 있습니다. 그러나 파일 시스템 UUID/FAT32 일련 번호가 정확하다면 GRUB에 대한 우선 순위가 더 높습니다. GRUB가 올바른 UUID/FAT32 일련 번호를 가진 파일 시스템을 찾을 수 있는 한 펌웨어가 무엇을 호출하든 상관하지 않습니다. 그것. 일련 번호가 변경된 것으로 나타나므로 GRUB는 찾고 있는 이전 일련 번호를 찾지 못하고 추측된 hd1,gpt1식별자로 대체됩니다. 이 식별자 역시 분명히 잘못된 것입니다.
