this version is not genuine

[nikilai]

I am lost. Finally my laptop has to send back for repair.

I deleted the 'System' and repaired the boot files with a thumb drive created by another computer because my laptop doesn't has an optical drive. When tried to reboot to Windows, it is found nothing come out after 'Preparing for your desktop' but a message about 'this version is not genuine' at the right bottom corner. I am not sure why it happens. Do you think it is the reason is the recover thumb drive is created by another computer?
Without the 'System" partition, it couldn't get back to the pre-set recovery mode as well. The only solution is repair by sending back to the manufacturer.

Ignore errors produced when clicking on the Copy button - they simply mean that the tool could not create the backup files for some reason. The data is still copied to the clipboard for pasting to your response.

Please also state the Version and Edition of Windows quoted on your COA sticker (if you have one) on the case of your machine (or inside the battery compartment), but do NOT quote the Key on the sticker!
