Need Help Installing Ubuntu 18.04.3

[jasperstrange]

Hey Ubuntu Community,

I am not the most knowledgeable in this field, and I am having a tough time installing Ubuntu on my computer, where I partitioned the disk. I followed this guide and got to the point where I can "try ubuntu without installing" or "install Ubuntu".

I spent a couple hours reading about ways to get rid of the errors that pop-up, and have solved a couple but I've hit a wall.

Error Message:

```

```

My computer is a Lenovo Y50-70
-nvidia GTX 960M
-Intel(R) Core(TM) i7-4720HQ CPU @2.60GHz

I was able to get rid of some error messages with:

```

nouveau.modeset=0

```


But i have yet to be able to actually use Ubuntu.


Thanks in Advance for any help

Often ACPI errors can be ignored.

If not mounting the / from installer, I would first confirm you downloaded it correctly lwith md5sum.
https://help.ubuntu.com/community/BootOptions
https://help.ubuntu.com/community/HowToMD5SUM

Some also report that different port, different flash drive or using a different installer solves issues. No one issue.

You will need nomodeset to boot both live installer & first boot of install or until you install the nVidia driver.
At grub menu you can use e for edit, scroll to linux line and replace quiet splash with nomodeset.
How to set NOMODESET and other kernel boot options in grub2 - both BIOS liveCD & grub first boot ( also UEFI with grub)
How to add boot parameters, grub menu after install (also grub when UEFI)

https://help.ubuntu.com/community/Grub2

If wrong nVidia driver or upgrade, you must purge & install correct driver

Thanks A lot. I was able to get Ubuntu up and running with ease after your help. Now I am trying to figure out why I have no WiFi...
