Aspire V3-372 in "Restart System"-Loop after installation of Ubuntu 20.04.3

I tried to install ubuntu 20.04.3 on my Acer Aspire V3-372. Installation via usb worked perfectly. However, after finishing and rebooting, the system is in an infinite reboot loop, similar as reported here: The screen flashes "Restart system" when the acer logo appears, and few seconds after that, it reboots again.

However, I was not able to fix this issue via the UEFI boot management (aka InsydeH20 Setup Utility). In the option "Select an UEFI file as trusted for executing", I indeed find the ubuntu installation and the efi file, and it is set.(This is a common solution for ubuntu installtion/booting options, e.g. here here and here )

The issue persists.

I tried a lot now from solutions of similar issues provided at different places. Most significant change was the error "no bootable device found" when I once tried to define the efi partitions. Of course, I repeated the installation several times, so it does not seem to be a broken installation. The ubuntu Live system also works perfectly. What could I try?

Boot to the live ubuntu stick. Open the terminal command prompt. Enter 'boot-repair'. If the command isn't found in the installation live stick then follow the directions in this link.

Hi @klaush,

# Try to get the BIOS page.

1. Turn OFF the unit.

2. Press and hold the F2 key and turn on the unit.
3. You will be in setup utility page.
4. Once you got the screen release the F2 key.
5. Tap on F9 key and hit enter key without changing the option.
6. Tap on F10 key and hit enter key without changing the option.
7. Your unit will restart by itself.

Check this T/S and post the result.

Hi @Easwar , thank you for the reply! Good idea to try to reset to the default boot settings. Unfortunately, nothing changed after going through your steps: It is trapped in the "restart system" loop again.
