HAOS boot problem

Installation
1

I have HAOS 16.2 installed on a VM in Proxmox.

I’ve forwarded the /dev/ttyS0 and /dev/ttyS1 ports.

qm set 101 -serial0 /dev/ttyS0
qm set 101 -serial1 /dev/ttyS1

The ports are working, but there’s a problem with HA booting after a reboot.
I have to manually select the system boot option in Grub because the system console is displaying some garbage.

How can I fix this and restore autoboot?

The solution turned out to be very simple. Just changing a single line in /mnt/boot/EFI/BOOT/grub.cfg from set timeout=1 to set timeout=0. This eliminates the waiting time – GRUB immediately boots the system, before data from the port can block it.
