A technician is troubleshooting a Windows 11 workstation using a UEFI/GPT configuration that fails to boot following an unexpected power loss during a system upgrade. The computer displays a stop screen with error code 0xc00000e, signaling that the boot selection failed because a required device is inaccessible. The technician launches the Command Prompt from the Windows Recovery Environment (WinRE) and determines that the hidden EFI System Partition (ESP) has been assigned drive letter S: and the main Windows installation volume is recognized as drive letter D:. Which TWO of the following command-line actions should the technician perform to rebuild the UEFI boot files and repair offline corrupted operating system files?
- Execute bcdboot D:\Windows /s S: /f UEFI to recreate the boot loader files on the EFI System Partition.Cevap
- Execute sfc /scannow /offbootdir=D:\ /offwindir=D:\Windows to repair protected system files on the offline Windows volume.Cevap
- CExecute bootrec /fixmbr to rewrite the Master Boot Record on the primary system disk.
- DExecute dism /online /cleanup-image /restorehealth to replace corrupted component store binaries.
Cevap
The technician must execute bcdboot D:\Windows /s S: /f UEFI to rebuild the boot configuration files on the EFI partition and execute sfc /scannow /offbootdir=D:\ /offwindir=D:\Windows to scan and repair corrupted operating system binaries in the offline Windows directory.
To repair a corrupted UEFI startup environment from WinRE, the bcdboot tool must be pointed to the OS directory (D:\Windows) and the target EFI partition (S:) using the UEFI firmware flag (/f UEFI). Additionally, to scan and repair protected system files on an offline OS instance, sfc must be executed with the /offbootdir and /offwindir parameters set to the offline OS partition.
