Windows 11 update error encountered when upgrading from Windows 10
Is there a way to fix this error when I was trying to upgrade my laptop from Windows 10 to Windows 11, it says: Windows 11 Setup Setup has encountered a critical error Sorry, we're having trouble...
If you want to see exactly where Windows 11 Setup failed, open this file after a failed update:
C:\$WINDOWS.~BT\Sources\Panther\setuperr.logSearch inside it for “0x80888002” or “0x40008” — you’ll often see clues such as:
SP_EXECUTION_OP_PREPARE_SAFE_OS failed; error code = 0x80888002That indicates the problem happened while preparing the Safe OS. It usually means disk, partition, or recovery layout corruption.
You'd better format the disk with GPT and make enough room for recovery partition in order to fix Windows 11 update error encountered (Error code: 0x80888002 - 0x40008) when upgrading from Windows 10
It could be the last option as I don't want to reinstall all apps. This would take hours to be done not to mention the time for file backup.
