- I have made a flash disk booting into uefi mode.
- Then i have added windows 7 pe and windows 8 pe. both of them loads in uefi mode.
- i start windows 8.1 setup from a folder in flash disk. when it starts copying files. computer hangs immediately.
- if start my laptop in legacy bios mode, i can install windows 8.1 setup in windows pe successfully.
Why can't i install windows 8.1 setup from a Windows PE which is in UEFI mode ? what am i doing wrong ?
