Turn off Startup sound on Bootcamp only MBA

[bartonjd]

I am only allowed to have windows on my macbook air for work. I need it to not chime anymore on startup, I have tried
nvram SystemAudioVolume="%80"

in the terminal using a usb OSX recovery drive but for some reason that hasn't fixed it. Any ideas? Thanks!

Turn the volume all the way down.

Put an Ultrabook 'Intel Inside' sticker over the Apple logo and rip the speakers out.

I am not allowed to install OSX on this machine and lowering the volume in Windows does nothing. Appreciate any more suggestions

Are you referring to the Windows startup chime? If so, you'll need to adjust that within Windows itself. I'm assuming you're using Windows 7 since 8/8.1 have the chime disabled by default. The link below has the steps to disable it in 7:

The MBA boot chime is controlled by the volume setting (ok, I know this is true for OSX, perhaps windows is ignoring it), try muting audio prior to rebooting windows. If you're referring to the windows boot chime, does adjusting audio in windows have no effect?

Are you booting / running windows from a USB device? If not, I'd be curious as to the procedure used to load windows only onto your MBA.

Its the mac os chime. I can't turn off the volume because Mac os isn't installed. The chime setting is in the nvram I believe which cannot be altered by windows. But that is all I know

Don't shut down - just put the MBAir to sleep, or hibernate. I know, not a 100% fix, but you don't get a boot chime unless you boot/restart.

boot Camp doesn't work properly on my MBA and so windows will not sleep or hibernate any ideas on that? Thanks

Maybe some of your drivers are not correct, or missing.
Does the device manager show any problems?

There's a real possibility that the full set of drivers are only available from Apple.
You can download a current set from the Boot Camp Assistant.
And, you could access that without having OS X on your MBAir, by installing a bootable OS X system on an external drive - very useful to have if you need to support the Mac hardware/software.

Boot into OS X from USB stick / external HDD / whatever. Mute volume in OS X. Reboot.

Ah, OS X is completely removed from the system. That makes more sense. In that case the above suggestions would probably be your best bet. You'll need to somehow boot into OS X to fix that. Then you shouldn't hear it anymore.
