I try to upgrade windows 10 to windows 11 24H2 but at the end of upgrade I get this error: The installation failed in the SAFE_OS phase with an error during BOOT operation
I do upgrade from windows 10 to windows 11 23H2 without issues
Is an old PC with a 2 core cpu,
PS: 24h2 requires that the cpu has SSE4.2, and that is a hard requirement to upgrade. Any processor without 4.2 will be stuck at 23h2.
