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.
