On my late 2012 Mac Mini, I have installed both Mac OS X Mavericks (with FileVault) and Windows 8.1 (natively, not via Bootcamp):
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *1.0 TB disk0
1: EFI EFI 268.4 MB disk0s1
2: Apple_CoreStorage 859.0 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
4: Microsoft Reserved 134.2 MB disk0s4
5: Microsoft Basic Data Windows 140.2 GB disk0s5
That's working fine, and I can boot both Mac OS and Windows.
However, I'd like to be able to boot my Mac into Windows from the command line - without permanently changing boot settings.
To my understanding, this should do it:
sudo bless -mount "/Volumes/Windows" -setBoot --nextonly
The command produces no output. With --verbose, it tells me this:
EFI found at IODeviceTree:/efi
Mount point for /Volumes/Windows is /Volumes/Windows
Mount point is '/Volumes/Windows'
No BootX creation requested
No boot.efi creation requested

Checking if disk is complex (if it is associated with booter partitions)
GPT detected
Booter partition required at index 6
System partition found
Preferred system partition found: disk0s1
Returning booter information dictionary:
{type = mutable dict, count = 3,
entries =>
0 : {contents = "System Partitions"} = (
disk0s1
)
1 : {contents = "Data Partitions"} = (
disk0s5
)
2 : {contents = "Auxiliary Partitions"} = (
)
}
Path to mountpoint given: /Volumes/Windows
IOMedia disk0s5 has UUID D4FC6318-275B-427D-B039-3AB033DE8ACC
Setting EFI NVRAM:
efi-boot-next='IOMatchIOProviderClassIOMediaIOPropertyMatchUUIDD4FC6318-275B-427D-B039-3AB033DE8ACCBLLastBSDNamedisk0s5'
Setting EFI NVRAM:
IONVRAM-DELETE-PROPERTY='efi-boot-file'
Setting EFI NVRAM:
IONVRAM-DELETE-PROPERTY='efi-boot-mkext'
Setting EFI NVRAM:
IONVRAM-DELETE-PROPERTY='efi-boot-kernelcache'
NVRAM variable "boot-args" not set.
That looks good to me - but the command has no effect, after rebooting, I'm back in Mac OS X.
What am I doing wrong?
