I want to test drive U LTS, but I can't get into the Live environment. I'm getting stuck during boot (the same issue here, though just the first one):

iwlwifi 0000:02:00.0: Unsupported splx structure

and the solution involves "pressing e during the grub menu and adding nomodeset to the end of the Linux line." However, since I'm just booting from live (remember I want to test first), I don't have grub, just the default boot menu.

How can I edit whatever is being modified with the commands above, so that it's built into the USB?

  • Hi. Do you use UEFI or BIOS? –  Oct 15 '16 at 18:22
  • Hi, @MarkYisri! I use UEFI. – Khashir Oct 15 '16 at 20:18
  • Press e during the live boot menu. –  Oct 15 '16 at 21:01
  • Wow, that simple--thanks so much. Now, graphics were crap, as you probably guessed (couldn't go higher than 800*600 res)--I opened the App Center and installed the nvidia drivers, but that didn't help. Will I be able to get proper graphics/resolution once installed? – Khashir Oct 16 '16 at 02:50
  • @MarkYisri: Will you be submitting an answer? I will create a new question (referencing this one), I think it would be better if it had an actual answer. If not, let me know, and I'll submit one, crediting you. – Khashir Oct 21 '16 at 22:36
  • I will submit an answer, can you please tell me where the question is. –  Oct 21 '16 at 23:12
  • Well, it's the last bit, which you answered by mentioning that for UEFI, I have to press 'e' from the live menu. The follow-up question will be how to get working nvidia drivers (using your comment, I got 16.04 installed and loading, but with 800x600 res)—there are so many posts I'm not sure what the right answer is. – Khashir Oct 21 '16 at 23:14

The UEFI Ubuntu USB images also use GRUB. Simply press e during the bootup menu to fix the problem.
