"error: serial port `com0' isn't found" Error When Trying to Boot Arch

Hi everyone,

I'm in the process of installing Arch Linux on my new laptop(Acer Aspire 5) and I'm encountering a specific issue. After powering on the computer with the USB flash drive to boot Arch Linux, I'm seeing an "error: serial port `com0' isn't found" message, and the boot process stops.

I've recorded a short video demonstrating this issue: https://www.youtube.com/watch?v=V0HrLA5 … annel=leaf

My computer works perfectly fine with Windows, so I suspect that this issue is related to the attempt to boot Arch Linux.

What is the issue?  That should be a harmless error.

I can't install arch, you can see that in video. I tried to wait about 5 minutes, sound doesn't stop and error doesn't disappear

The serial port warning/error is probably not the issue.
Do you have secureboot enabled?

no, secure boot is disabled(you can see that in the video).  I have tried an older iso, and it even shows menu, but when I select an option, it just reboots(https://youtu.be/dBWVxMi0Kpo)

Re: "error: serial port `com0' isn't found" Error When Trying to Boot Arch

Can you boot in legacy mode?
Are any UEFI updates available for the system?
What specific HW is this? https://en.wikipedia.org/wiki/Acer_Aspire_laptops

How exactly are you writing the USB key? dd?
Does any other live distro (eg. grml) boot?

On a remote chance, disable windows fast-start (3rd link below)
It'd possibly cause this but should™ not when booting an external medium.

Re: "error: serial port `com0' isn't found" Error When Trying to Boot Arch

no I can't boot in legacy mode(buttlon is not active), maybe because my laptop doesn't support it
no, there is no updates https://www.acer.com/us-en/support/prod … /downloads
It is A515-48M

I write it by rufus
debian show practicly the same trouble, but without this error(just black screan with "beep" sound)

I have not tried it, but unfortunatly it doesn't help

The model shows up w/ that record
https://bbs.archlinux.org/viewtopic.php?id=286986
https://forums.linuxmint.com/viewtopic.php?t=401391

Can you boot grml (afaik should still use syslinux to boot)?

grml wouldn't start grub?
Are you sure you end up booting from the proper device?
Did you try a different USB slot?

some how i even can start grub by creating usb image with manjaro, but every time when i select the option "Boot with open source drivers" or "Boot with open proprietary drivers", it goes to reload)

Re: "error: serial port `com0' isn't found" Error When Trying to Boot Arch

What I meant is that an attempt to boot grml should not result in  "Welcome to GRUB" because it boots w/ syslinux.
