Cannot Install Ubuntu: A TPM error (7) occured

[toastythomas]

Here's a quick back story.

My school was throwing away a HP Compaq Pro 6300 Business PC with Win 7 on it. The boot time was terrible and the login required an administrative password that I did not know. I removed Win 7 and grabbed a Ubuntu 15.10 64 bit ISO USB image.

I boot, click install image and I get this error line.

A TPM error (7) occurred attempting to read a pcr value.

Ubuntu failed to install.

I looked around for an answer and they seemed to vary. Given the back story, I hope someone will give me an answer that will help my circumstance. Thanks.

What piece of hardware inside the computer could I replace to make it work?

It is possible you may be able to enable/disable TPM from your BIOS.

It may be listed as TPM or security chip.

 

My guess is it is disabled an you want to enable it. However if it is enabled you may want to try disabling it.

It is a business grade laptop, which means it has a Security chip on-board. Look in the BIOS for security chip and enable it. If it s reporting an error, it means its disabled. That is error 7. I got the same error on my ThinkPad, it was disabled. Good luck!

 I was told this by a friend and I have searched the BIOS through and through and there was no option. Like I said in the OP, what piece of hardware can I replace to fix this issue? Motherboard?

In a notebook, If you're going to replace the motherboard you may as well replace the entire machine. It will probably be cheaper.
But yes, The chip is on the motherboard.

Is it possible to bypass the tpm or try a different linux?

 

i can't imagine thats impossible. It sounds almost like hdd encryption of was on and needed disabling.

you can blacklist the module. However you have to actually install it first.
I don't believe there is a way to disable modules during install via the GUI installer.
I could be wrong, It's been a while since I've installed Ubuntu.

The computer runs for over $1000 USD. A motherboard off of Newegg is $50 USD.

Is the security chip a physical item on the board that I could yank out?

Laptops are custom boards not average desktop boards..

And parts are soldered nowadays...

Get an Arch Linux live CD and try to boot that, then report back.

Does it have to be a CD?

The ISO i meant, in general, make bootable USB and boot it.

OK, I remoted into the BIOS of one of the computers at work to give you this screenshot: BIOS -> Security -> System Security -> Embedded Security Device. This option is TPM in "HP-language". However, I do not recall running into issues with CentOS with the option enabled before.

 

Alternatively, change "Reset to Factory Settings" to Reset and see if that helps.

Woops, Not sure why I assumed it was. My bad.
You may be able to replace the motherboards. I'm pretty sure all intel motherboards these days have security chips on them. But having an option to turn it on and off would be nice.
The problem however may still be in non-generic hardware. Many OEMs (HP, Dell, Acer... etc) Use custom parts in their machines. For example the motherboard will have a custom connector from the PSU to the motherboard, So if you replace the Mobo you may also need to replace the PSU. The other Issue would be finding a motherboard with the same CPU socket, you may end up needing a new CPU as well. At that point you might as well go all out and build a whole new rig.

How long are you waiting for the system to boot?
On the boot selection screen press Tab and add "debug" to the kernel parameters, also remove "quiet" and "splash" if they're there.
The line should look something like this:

linux /boot/vmlinuz-linux root=/dev/sda3 initrd=/boot/initramfs-linux.img debug

Then press enter. You should get a much more verbose output.

Sorry for the long reply, it's been a full week of middle school and Counter Strike.

Anyways, pressing tab does nothing.
