Acronis True Image Premium BootCD issue with Logitech G710+

Hallo, my config is:

i7-3770k
Asus P8Z77-V DELUXE LGA1155
Logitech G710+
Acronis True Image Premium BootCD (newest version)

The mechanical gaming keyboard works flawless in combination with Windows 8.1 home.
Only the Acronis BootCD gives me error messages:
Suddenly after booting the Acronis True Image Premium BootCD I can hear a continuous peeping of my motherboard. After checking an empty field in the BootCD software I can see a permanent striking of the key "666666666666666666......"
If I shut down the BootCD i can see the following keys: ^66^66^66^66^66^66^66^66^66
(the circel in the middle 6 is black) during the shutdown messages of the BootCD.
If I want to restore a backup image via hd with the BootCD I must first unplug the keyboard.
With another keyboard I got no errors with the BootCD.
Can anyone help me to fix this issue?
Thanks,
Michael.
