A few days ago, I bought this laptop, and now I want to change its OS (Windows 7) to Ubuntu but failed.

I burn it to a USB stick, set BIOS to startup from USB and it worked. I followed the install steps to install Ubuntu, it was a success. But when I restart the computer after installation, it's not working, it'll be continual reboot at start up until I shutdown or let it start up from USB stick.

Can anybody to tell me this is why? Please help me to resolve it.

It might be because you installed GRUB on a partition. To resolve this:

  • Boot from the Live USB.
  • Open a terminal (Ctrl+Alt+T).
  • Run the following commands:

    sudo grub-install /dev/sda
    sudo update-grub

    Here, /dev/sda is the name of the harddrive. To check the name of the harddrive, run sudo fdisk -l.

In the screenshot, the devices /dev/sda1, etc are the partitions, whereas /dev/sda is the harddrive.
