摘要
本文說明如何使用Microsoft提供的範例腳本來增加修復磁碟分區大小，以啟用 WinRE) (Windows 修復環境的維護。 WinRE 是一項可協助您疑難解答及復原各種系統問題的工具，例如啟動失敗、惡意代碼感染或系統檔案損毀。
WinRE 需要足夠的修復磁碟分區空間，才能成功安裝 WinRE 更新。 不過，有些裝置的修復磁碟分區空間可能很小。 範例腳本可協助您調整裝置修復磁碟分區大小，以避免潛在的 WinRE 維護失敗。
如何使用此腳本將 WinRE 磁碟分區大小增加 250 MB

執行範例腳本的步驟
若要執行此範例文稿，請依照下列步驟執行：
-
開啟文字編輯器。 例如，若要開啟 Windows 記事本，請以滑鼠右鍵按兩下 [ 開始]，按兩下 [ 執行]，輸入 notepad.exe，然後按兩下 [ 確定]。
-
將範例文稿複製並貼到開啟的文字編輯器。
-
將腳本檔案 儲存為Powershell_ExtendWinRE_or_CreateNew.ps1 至您選擇的位置。 例如，將腳本檔案儲存至 C://Documents/WinRE_Script。請注意此位置路徑，就像您在步驟 7 中使用此位置一樣。
-
重新啟動您的裝置。 這很重要，因為您的裝置上可能有擱置中的磁碟分區作業，必須先完成，腳本才能安全地增加 WinRE 磁碟分區大小。
-
裝置重新啟動之後，以系統管理員身分開啟PowerShell。 其中一個方法是以滑鼠右鍵按兩下 [開始]，然後按下 [終端機 (管理員) ] 。
-
輸入 mkdir <新備份目錄> 路徑，然後按 Enter。 例如，輸入 mkdir C：/WinRE_backup，然後按 Enter。這會建立名為「WinRE_backup」的備份目錄，腳本可能會在還原原始磁碟分區失敗時使用。 請注意此備份目錄的位置。
-
輸入 Powershell.exe -ExecutionPolicy Bypass -File <您儲存 winre 腳本>位置的路徑 。 例如，輸入 Powershell.exe -ExecutionPolicy Bypass -File C：/Downloads/WinRE_Script。
注意事項
-
假設腳本成功完成，您的裝置現在將至少有 250 MB 的可用空間，並且可以安裝 WinRE 維護更新。
-
刪除您在步驟 3 中建立的備份目錄，因為它已不再需要。 例如，刪除 C：/WinRE_backup 目錄。
您可能會遇到的問題，以及如何修正問題
如果您從腳本收到下列錯誤訊息，表示裝置上的可用空間不足，無法完成重新分區。 在此情況下，請遵循Microsoft釋放 Windows 磁碟驅動器空間的指導方針。 完成之後，請重新啟動裝置，然後再次執行腳本。
注意 有些裝置的操作系統磁碟分區可能有足夠的可用空間，但是磁碟驅動器太分散，而且會無法執行磁碟分區。 在此情況下，請使用本指南來 重組您的磁碟。
此文稿假設您已啟用 WinRE。 如果您收到此錯誤訊息，表示您的裝置沒有啟用 WinRE 磁碟分區。 對於某些工作負載，裝置建立者可能會選擇不包含 WinRE 磁碟分區。 如果您的裝置沒有 WinRE 磁碟分區，則不需要維護。 如果您的 WinRE 磁碟分區發生問題，請依照 WinRE 疑難解答功能中的步驟進行。
當您嘗試在具有自定義磁碟分區版面配置的裝置上執行此腳本時，可能會遇到問題，其中裝置在操作系統 (操作系統) 磁碟分區與修復磁碟分區之間有另一個磁碟分區。 若要解決此問題，您需要移動或刪除操作系統磁碟分區與修復磁碟分區之間的磁碟分區，讓修復磁碟分區具有與操作系統磁碟分區 + 1 相同的索引。
例如，如果操作系統磁碟分區為索引 2，則修復磁碟分區應為索引 3。 請小心不要刪除或修改任何重要的磁碟分區區，例如系統或開機磁碟分區。 移動或刪除磁碟分區區之後，您需要重新啟動裝置以套用變更並更新磁碟分區索引。 然後，您可以再次執行腳本，它應該可以如預期般運作。
