So i have been running a dual boot set up of ubuntu and windows on my laptop and suddenly tonight both my usb boot disk and the partition its self just loads to a black screen.

Grub seems to be working fine as my windows partition boots fine. Im completely stumped
My laptop is a Lenovo yoga 720

I would start with figuring out why the usb liveboot stick doesn’t work.

  • Might fix the partition boot problem
  • With the stick you can try the easy Boot-Repair

Unfortunately all I came up with is checking some BIOS settings like Secure Boot Disabled, Boot Mode which depends on your install, USB Boot Enabled, and things like that.

Edit:
Just to be sure. Have you cheched that the boot stick works or as I understood that boot stick is the same one you installed Ubuntu with? And you haven’t changed the boot stick in any way?

I’ll try those boot settings when I try next. The first USB boot stick I tried I know works since I used to install my desktop this week. And I tried making a second innrufus but neither worked
