Sometimes, you may have to join a meet immediately or submit a report urgently. But your system won’t respond. Ubuntu won’t boot. But don’t worry. Automatic Cable has your back. Ubuntu is generally trustworthy, but sometimes it may not react the way we would like it to. This article presents some common causes and how to repair your PC when Ubuntu does not start.
What To Do If Ubuntu Won’t Boot?
Generally, for any Linux application, the follow the steps. Especially for Ubuntu, if your system is not booting, try the given steps, and you will be good to go.
Is There a Bootable Device Responsible for Creating Ubuntu Boot Problems?
If Ubuntu won’t boot, it may be because a boot disk is attached, and it usually occurs as soon as the installation is done. It is due to the reason that the Ubuntu boot disk is set as the boot device. It is so problematic that the installer instructs you to remove your installation media before starting the installation.
Open the UEFI / BIOS system or the start order menu to check the current launch device. You can access both on the POST screen, which appears where your PC powers up. If you have trouble finding the start order menu, check the computer documentation (or motherboard).
GRUB Bootloader is Not Active
GRUB is a bootloader that verifies that the operating system boots. The double-booting machine will list and launch all installed applications, including Windows. But, simultaneously installing Windows next to Ubuntu may overwrite the boot loader, leading to Ubuntu booting problems. Other problems may damage the bootloader, such as a failed upgrade or a power failure.
Restarting your PC while holding Shift checks the GRUB bootloader. You should now see a list of installed applications; Navigate the menu using the arrow keys. The GRUB bootloader might be broken or overwritten if that didn’t happen. Fixing the bootloader is the only solution. (If you double-click, you’ll still be able to access Windows). In case you see GRUB Bootloader, skip to the next section.
Adjust the GRUB Bootloader to Boot Ubuntu. If GRUB does not load, then Ubuntu will not start. Fortunately, you can edit GRUB using the Ubuntu input media. Please restart the computer with the disc inserted and wait to load. Also, you may need to change the startup order, as described above. Please write a note of the launch order before changing it!
If the installation media is live, make sure you have a network connection and open the terminal. Enter:
Sudo apt-add-repository ppa: yannubuntu / boot-repair
sudo apt update
sudo apt install -y boot-repair
This will install the startup tool and start after the last command. Wait till the system scanning before selecting Recommended Repair. (There is also a view of advanced options, where you can choose the default OS, default disk or partition, etc.) Click Apply when done. Now you should restart your PC and start on Ubuntu. Otherwise, it will be there as an option in the GRUB bootloader menu.
If still Ubuntu won’t boot, you may choose to re-install Ubuntu. Do this without overwriting your existing files and folders, and it is one of the ways to fix it if Ubuntu does not start.
- First, turn on the live environment in your Ubuntu input media. Next, start installing Ubuntu. If the installer finds Ubuntu, select Reinstall Ubuntu.
- Select an option with the note “Docs, music, and other personal files will be saved …” Continue with the re-installation
- Of course, as a warning, you should already have a backup copy of all your Ubuntu data, and this can be manually with a backup tool or disk cloning tool.
- Once the installation is complete, Ubuntu will back up and activate.
Note: The Clear Ubuntu and Install option are not recommended unless other options fail. Also, your data should be cached.
Another reason Ubuntu won’t boot is the faulty hardware. Boot problems can be due to:
- Hard disk drive and Cable
- Power Supply Unit
After replacing faulty hardware, you will need to re-install Ubuntu from scratch without baking. Although it is a “burning world” approach, this will solve problems when Ubuntu does not start.
If you installed it or used Ubuntu for a while, it does not start; it does not mean an easy fix.
If the GRUB bootloader cannot be repaired, it may take a long time before your computer works. Another argument favors maintaining a backup, or at least syncing your essential data with the cloud!
By following the above steps, you will reboot any operating system, not only Ubuntu! This was out take on what to do if Ubuntu won’t boot. We hope you liked them!
