您好 Elaine，

感謝您聯絡 Microsoft Q&A 論壇！我了解您正在嘗試從 Windows 10 升級至 Windows 11，但 MBR2GPT 工具失敗，原因是找不到有效的開機分割區。

您提供的圖片顯示確實有系統保留分割區，但 MBR2GPT 日誌顯示 Disk 0 上所有分割區均未設定為開機，這表示開機分割區未正確標記，或 BCD 存放區未指向正確的分割區。

以下是解決問題的逐步指南，請依序操作：

1. 檢查哪個分割區為 Active

開啟 命令提示字元 (系統管理員) 並執行：

diskpart
list disk
select disk 0
list partition

• 如果沒有任何分割區標記為 Active，您需要設定正確的分割區。

2. 將系統分割區標記為 Active

如果您有一個小型分割區用於開機檔案，選取它並執行：

select partition <number>
active

3. 修復開機檔案

仍在命令提示字元中執行：

bcdboot C:\Windows /s C: /f BIOS

• 這可確保開機檔案正確配置。

完成上述步驟後，您可以再次執行 MBR2GPT。期待收到您的更新。如果問題仍然存在且需要進一步協助，請點選「新增留言」隨時詢問我，感謝您的努力！
