Zorin OS 17 doesn't boot after installation, straightly boots into laptop boot screen

[Magnibigg]

I installed Zorin OS Core 17 on the same laptop I installed 16.3 on. After reboot, it doesn't boot, instead it goes straightly into boot screen of the laptop. But when I went to run the installer again, it detects that Zorin OS 17 is installed. Please help.

Make sure you have disabled Secure boot and Fast boot in Bios.

And provide some information about your device like especially what graphics card you have.

Try by editing grub parameter while booting

[HOW TO] add a grub parameter

There may be times that a user must add a specialized grub parameter in order to overcome an issue. The purpose of this guide is not to provide parameters, as that would be a case by case basis. It is to provide a guide on how to add one. To add a parameter, in a terminal (TTY, Recovery Prompt or Terminal Emulator) run: sudo nano /etc/default/grub Arrow key down to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" and place your parameter within the quotation tags. For example if you are adding th…

Let me tell you. I installed Zorin OS 17, and it installed just without any errors. The Live Session also worked fine. But after installation, when I went to restart, it boots into the Boot menu (F12), not Z17. Again, I went to install. That's when I saw that Z17 has already been installed. It's one of my main laptops alongside the PixelBook, as my main Windows PC hasn't been repaired yet. So, please come up with a solution.

Maybe, I'll reinstall Windows 10 or Z16.3 on it, if I have no choice.

But @littlekun, I'll surely try the tutorial you quoted to see if anything changes.

Did you install as EFI boot or Legacy boot?
These are settings in your BIOS as well that you can check from booting to your motherboard.
In the meantime, I would recommend running Boot repair by booting from the LiveUSB of Zorin:

You can relay the boot repair log if you have any trouble with it.

I was having similar issues installing ZorinOS Pro 17 on my Acer laptop in EFI boot. I made sure to disable secure boot.

Zorin successfully installed but when it rebooted, my laptop displayed the "No Bootable Device" error message.

I was able to install in legacy boot and it's working.

If possible may I suggest you install to an external SSD for a number of reasons.

1). If you install both GRUB and the OS to the SSD you can still boot back to an earlier version of Zorin 16.

2). the SSD performance is phenomenal.

3). make sure you use gparted to create a boot partition formatted to fat32, set flags to boot, esp and partition the system to ext4 format.

4). A 256gb ssd can be had for under 40 dollars, although 128gb should suffice.

5). Finally, use Timeshift for system snapshots/backup/restores in worst case scenarios.
