Help me! Dont iniciate

[Gi_Mendonca]

When turning on my Acer, a window appeared that had never appeared before:
GNU GRUB VERSION 2.04+dev86. 0599233-5bem1

Below are the options:
*ENDLESS OS
ADVANCED…

However, in none of the options, the PC continues the connection. It gets stuck. I don’t understand anything about setup, boot, config, none of that!
Can anyone help me?

How should I proceed?

Hi there,

Sorry this update is not working on your device. You can follow the comment Upgrade 5.0.6 to 5.1.0 failed, ASUS frozen at Bios to boot with previous version.

I believe the step 3 is the GRUB menu you see. In the GRUB menu, you can choose “Advanced …” , then the second item should be “Endless OS 5.0.6 …” (for example) and boot with it.

After you boot into the system. Please help us have the debug log as the step 4 & 5 in the comment. Thanks!

Hi! You can try the method mentioned in

Release | Endless OS 5.1.1

By the way, the document Booting the previous OS version shows how to boot previous version (Rollback) with GRUB. It includes a demo video, too. Some computers, such as Acer Nitro AN515-54 with Intel® RST feature may boot failed after upgraded from EOS 5.0.x to EOS 5.1.0. “Rollback to EOS 5.0.x with GRUB, boot into the system and upgrade to EOS 5.1.1 again” can avoid the the issue.
