I was running out of space on my root partition, so I made a backup with the default Ubuntu backup software to my second HD. After resizing the windows partition I get the following errors:
[ 1.123158] tpm_crb MSFT0101:00: [Firmware Bug]: ACPI region does not cover the entire command/response buffer. [mem 0xfed40000-0xfed4087f flags 0x201] vs fed40080 f80

Welcome to emergency mode! After logging in, type "journalctl -xb" to view system logs,
"systemctl reboot" to reboot, "systemctl default" or ^D to try again to boot into dafault mode.
Press Enter for maintenance (or press control-D to continue):
I tried to boot a live-USB and doing boot repair. I also tried restoring the backup I made through the live-USB, selecting the backup location: "/media/2TB_HDD/Backup/Ubuntu" but this gives me the following error:
storage location not available, waiting for Google
The tpm error is probably from the "Trusted Platform Module" chip.
A Trusted Platform Module (TPM) is a specialized chip on an endpoint device that stores RSA encryption keys specific to the host system for hardware authentication. Each TPM chip contains an RSA key pair called the Endorsement Key (EK). The pair is maintained inside the chip and cannot be accessed by software.
The PKCS error probably has to do with Nvidia drivers being out of date, or not "signed".
Try turning off Secure Boot in your BIOS, and see if it solves one/both errors. Otherwise, if you can find a way to turn off the TPM chip in your BIOS, that'll take care of the first errors (but may cause a problem in Windows... you'll have to check).
