Boot Problems on Acer Aspire ES1-533

[urstru]

I'm unable to install and boot ubuntu on an Acer Aspire ES1-533. Pre installed was Win 10 which I removed.


Acer BIOS is Version V1.08
Secure Boot is Disabled.
Current TPM (TCM) State: Not Installed
Boot Mode: UEFI (Cannot be changed...)


The installation process freezes when installing grub, even the mouse pointer cannot be moved after freeze.

Before the ubuntu installation program starts, a short message shows up: Problem loading UEFI:db X.509 certificate (-65)

I made a check with boot repair: http://paste.ubuntu.com/p/v6fKmJxX5y/


Happy for every support ...

Have you updated UEFI from Acer, many have needed that.
Is Linux entry named by you after enabling "trust"?

You may want trust on the unknown/shim entry as to enable trust you have to have Secure Boot on.
