Dear Maintainer,

Steps to reproduce:
Set GRUB_TIMEOUT_STYLE=hidden in /etc/default/grub

Expected behaviour:
Grub remains hidden during boot.

Actual behaviour:
* If Windows is set up as a default:
  Grub appears as a short flash after the timeout is done, and before
  the Windows bootscreen appears
* If Debian is ser up as default:
  Grub appears to show that it loads the kernel.

I am not entirely surprised by the fact that grub appears
on screen when booting Linux (after all, it actually still has
to do something there), However, when it boots windows and
just hands off to the next loader, IMHO there is no reason
for grub to appear on screen - so a completely "silent" boot
should be possible.

Kind regards,
Ralf
