So, my brother gave me his old notebook since he got a new one. It had Windows 10.
I installed Ubuntu 14.04.4 LTS from my pendrive, choose the option to wipe all disc and install Ubuntu. Logged in on my home wifi and all, the installation seemed OK from start to end. Then it asked me to restart and the notebook doesn't turn on anymore. It gives me a black screen and keeps like flashing, turning off and on again.
If I press F12 after the motherboard logo and choose to try the Ubuntu from pen drive it runs nicely.
What can I do?
Thanks in advance
