ACPI BIOS Error (bug) : Could not resolve [\_SB.PCIO.SATO.SPT4._GTF.DSSP], AE_NOT_FOUND error booting from USB Ubuntu 18.04(LTS)

I have installed yesterday Ubuntu-18.04(LTS) 32GB USB with ext4 filesystem with along with fat32 partition. It was working nice. I worked on system full day. And shutdown the system. Next day I plugged this USB stick in Windows-8.1 System. It is installed on partition /dev/sdc5, ext4 15GB partition. Now I try to boot from USB It is showing error message
ACPI BIOS Error (bug) : Could not resolve [\_SB.PCIO.SATO.SPT4._GTF.DSSP], AE_NOT_FOUND

My Question is:

What may have cause this problem.?

How can I solve this?

There is also another problem occurred with Windows-8.1, where I plugged this USB stick in. It is that the windows system unable to connect to modem/internet. However I uninstalled/reinstalled/update driver. But that same network card works when I boot another USB live stick (as Try Ubuntu). It was working a day on that Windows system.

May the Ubuntu installed on USB have changed something on board, that do not let Windows/drivers connect to modem?
