How to fix the issue of not being able to enter the sys…
If Ubuntu fails to start, you can try the following troubleshooting methods:
- Rebooting your computer: Sometimes restarting your computer can fix startup issues.
- Check the boot sequence: press the corresponding key (usually F2, F10, or Delete) when starting the computer to enter the BIOS settings interface, and verify if the boot sequence is correct. Make sure the hard drive (typically SATA or IDE) is at the top of the boot sequence.
- Check the startup disk: If an error message like “Boot Device Not Found” or “No Bootable Device” appears during startup, it could be due to issues with the hard drive. You can try reconnecting or replacing the hard drive.
- Fix startup issues: If Ubuntu is having trouble starting up, you can try using the startup repair feature. Press the Shift key during startup to enter the GRUB menu. Select “Advanced options”, then choose “Recovery mode”. In recovery mode, select “Repair broken packages” or “fsck” to repair the file system and other options.
- Reinstall Ubuntu: If the above methods do not solve the problem, you can consider reinstalling Ubuntu. Start by using the Ubuntu installation media (such as a CD or USB flash drive) to enter the installation interface, then choose the “Install Ubuntu” option. During the installation process, select “Upgrade Ubuntu” to keep your existing files and settings, or choose “Erase disk and install Ubuntu” to completely reinstall Ubuntu.
If none of the above methods can solve the problem, it is recommended to consult with professional experts or the Ubuntu community for further assistance.
