Failing to power off when running the Arch ISO

My computer is HP OMEN 15-ce00x, with GTX 1050.
I have tried many timest to install Archlinux on my computer. However I couldn't power the computer even at the very begining of installation.
After I had booted the Arch ISO, I did nothing but to run the command

poweroff

And then it simply failed.
The error codes are like this:

[   90.036517] [736]: Failed to unmount /run/archiso/boomnt: Device or resource busy
[   90.036815] systemd-shutdown[1]: Unmounting 'run/archiso/bootmnt' failed abnormally, child process 736 aborted.

[  245.387981] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

Then I pressed the power button for a long time to shut it down by force.
And what should I do to fix this?

Re: Failing to power off when running the Arch ISO

Does `..# shutdown -h now` produce similar results?
