Try new ways to succeed:
F1 loading process is too slow.
In the Gandalf.ISO BOOT.WIM Copy it out, boot WIM with ventoy and start it normally (tested)
After entering PE, load ISO and set the drive letter to y. You can use the built-in program.
This avoids renaming before and after startup, and takes up less space of USB flash disk.
Optional operation:
Delete Gandalf.ISO In document BOOT.WIM Then save the ISO. This will not take up extra USB disk space.
