This is fixed in 2.02~beta3. Please reopen if you still can reproduce the problem there.

Please note that it is essential that the EFI route of activation is used to reproduce the bug. If the stick is booted using the standard route, a totally different interface appears, and commands can be edited without needing the control key. However this is no good as a workaround, as I am trying to get this to work on a system which insists on EFI booting.

Thanks.

I'm attempting to use the CentOS-7-x86_64-LiveGNOME-1511.iso image from a USB stick via EFI. The image was downloaded and put on the stick using dd if=xxx.iso of=/dev/sdb .

I have a Logitech K120 keyboard on a USB 1.1 interface. On selecting "e" from the Grub menu to edit out "quiet rhgb" from the relevant command, all goes well until I attempt to then execute the resulting commands using Ctrl-X. Instead of executing the commands it instead inserts x.

Similarly attempting to access a command prompt using Ctrl-C instead results in inserting a C.

The result of lsusb -v edited to just show the relevant device is shown below.

If I just boot without attempting to edit the command, it boots fine (but obviously with quiet and rhgb).

If I install grub2 by the usual methods, not using EFI, it works fine.

If you need any further information (that I don't yet know how to get hold of) please let me know.

With thanks in advance.
