did you create an Ubuntu USB flash drive? should just have to hit F12 at boot, and select your USB drive
I created the the USB boot drive with Pen Drive, UNetbootin, Rufus, Etcher
I can see the desktop for half a sec then it goes to a black screen. If I close the lid and press the power button, the same half a sec comes up and black again.
It seems Ubuntu booted but I just can't see it on 14.04
What exact steps did you guys do?
Is it a bios version problem?
USB 3.0 or 2.0 drive problem?
Update: 1
- I found an old USB 2.0 flash, Ubuntu 14.04.5 boots, ghex downloaded and I get
- "You have No Permissions to Edit the File"
- So I used the same method I made the 14.04.5 to create a 14.04 and as above. Black screen.
- I am trying to create the USB again with Etcher.
- Etcher doesn't work too
- Downloading 14.04.2 now
- Downgrade bios to
https://download.lenovo.com/consumer/mobiles/76cn38ww.exe and 14.04.5 still has No Permissions to Edit the File
- 14.04.2 doesn't have WIFI after boot
- Downloading 14.04.1 and .3 now, because WHY NOT, only been 10 hours
- 14.04.1 Black screen
- Chattr -i doesn't work, efivars mounted read-write doesn't work
- It does seems the new version cannot edit anymore.
I will try 14.04.3 if it doesn't work, then it's time to give up.
