I have been unable to get our of the Repair Process loop and I keep getting ACPI BIOS ERROR. I tried to recover the BIOS, but that hasn't worked. I need to reboot from a USB drive, but when I try to get the driver, I get a message that there is no software and no updates for my Notebook. Where can I get it? Thank you.

Disable the TPM in the BIOS.
