[LINUX] When I tried to install Ubuntu 18.04, "Initramfs unpacking failed: Decoding failed" was displayed and the startup failed.
Introduction
I tried to install Ubuntu from a live USB to get a dual boot environment for Windows and Linux Immediately after the BIOS screen, "Initramfs unpacking failed: Decoding failed" is displayed and booting failed. The solution at that time is described as a memorandum.
- The symptom was caused by the screen output from NVIDIA GeForce. If you're not using NVIDIA, reading this article may not help.
Installing Ubuntu For details on how to create and install USB media, see the following articles. https://qiita.com/koba-jon/items/240e6b9a9bee6a0b28cc
Symptoms
When I started the live USB, the following screen appeared (despair)
Cause
I was outputting the screen from NVIDIA GeForce, but it seems that this was not good. Ubuntu that I'm about to boot doesn't have the official NVIDIA driver (obviously) nouveau is working hard to get the GPU running. But it didn't seem to work.
solution
Press the e key when you go to the PC boot → boot OS selection screen (GNU GRUB). Since the screen will change to the kernel parameter setting screen, add the following to the end of the "Linux" line.
When you're done, press Ctrx -x or F10 to boot. This should start.
What to do additionally
Also, rewrite the boot parameter as follows so that it will not be the same next time.
- /etc/default/grub
#GRUB_CMDLINE_LINUX=""
GRUB_CMDLINE_LINUX="nomodeset"
After rewriting, reflect it with the following command.
If the desired resolution is not obtained, please refer to the following and install the official NVIDIA driver. https://sy07-sub.hatenablog.com/entry/2018/10/14/003750
