No, it does not work.
They definitely fail.
I tried your tutorial on a Lenovo X201. The tutorial shortcut gives no error (just a flash of command prompt) butshutdown /r /fw
gives the error "Boot to firmware UI is not supported by this system's firmware.(1)"
It seems in fact this only works on EFI (it works fine on EFI systems for me certainly - I tested it).
You should change the title to exclude the word "BIOS" as it does not work.
I guess not many people use legacy any more but if it isn't clarified it would confuse for sure as it doesn't work for legacy BIOS PCs.
Thanks Shawn, works like a champ :)
@Kari, something I should have brought up is there is a delay of about 30 seconds (stop watched it the second time around) from when you click the shortcut to when the system restarts. At least on my system. In fact, the delay is so long I thought the shortcut didn’t work, and was about hit it again when the PC suddenly restarted. At any rate I timed it the second time around and that’s where I got the 30 seconds from.
Is this normal? If so, just want people aware of such a delay.
Thanks.
Yes, that is normal. The default timeout delay in shutdown command is 30 seconds. It will be used if no custom delay is set with/t X
switch where X is preferred delay in seconds.
Some examples:
Shutdown in 30 seconds, using either default delay or setting delay manually to 30 seconds:
shutdown /s
shutdown /s /t 30
Restart in 30 seconds:
shutdown /r
shutdown /r /t 30
Restart to advanced startup options (/o switch) in 5 minutes (300 seconds) forcing all programs to close before restart (/f switch):
shutdown /r /o /f /t 300
Shutting down PC in one hour (3,600 seconds), forcing to close all programs, booting to UEFI settings next time PC is turned on:
shutdown /s /f /fw /t 3600
Restarting to UEFI settings immediately (no delay):
shutdown /r /fw /t 0
The last two sample commands above need to be run elevated because of the /fw switch. All other sample commands can be run without elevation.
