Enter device identifier of Melco installer flash drive or null line to exit:

You need to enter something like disk1, disk2, disk3, .... depending on what is shown under the previous heading "The following USB drives are available".

Make sure you don't enter the wrong USB drive as this would destroy all data on that drive.

Thank you for responding.When I try to instal program from hard drive of my Mac first time I enter disk 1 following process and it was looking like process is successful but Melco didn’t recognise and didn’t back up from flash memory(error 12). Then I try many times to repeat process and despite I was trying different options like disk0 disk 1 ( only those two are possible) and different USB drive but result is only: it is not USB flash? So I am stuck at this point. Maybe I have to uninstall and then reinstall program but I don’t now how to do this? Any advice?
