Ubuntu won't boot, caused by TPM

[stealthjong]

Hi,

My laptop, a HP Elitebook 8530w, is 6 years old, and, albeit rather fast for its age, not fast enough to properly run Windows 10. So I decided to install Ubuntu 15.10. Running from an USB-stick, Ubuntu made the laptop relive again, and it looks way nicer than Windows too. Anyway, I installed Ubuntu onto the hard drive (a 5400rpm HDD), and, to run Ubuntu from the hard drive, I was supposed to reboot. Sadly, I got this error:

ACPI PCC  probe failed

tpm_tis 00:01: A ATPM error (7) occurred attempting to read a pcr value

Gave up waiting for root device. Common problems:

- Boot args (cat /proc/cmdline)

  - Check rootdelay= (did the system wait long enough?)

  - Check root= (did the system wait for the right device?)

- Missing modules (cat /proc/modules; ls /dev)

ALERT! /dev/dis/by-uuid/a2f80475-78a1-4a4e-8d94-dcd74620a724 does not exist.

Dropping to a shell!

Busybox v1.22.1 (Ubuntu 1:1.22.0-15ubuntu1) buit-in shell (ash)

Enter 'help' for a list of built-in commands

(initramfs)

After a little reading up on TPM, and this problem in general, I tried switching TPM on and off in the BIOS (as administrator, with password), but to no avail. And I have the feeling other Linux distros have this same problem, since most of them run on the same kernel.

How do I fix this problem? 

Thanks,

Ubuntu is not supported on your system which means you need to go to a Ubuntu forum and ask for support from there.

Hi,

This looks like the bootloander can't find the boot partition. I don't think it's a serious issue. Follow this: http://ubuntuforums.org/showthread.php?t=1127779
