'No root file system is defined.' during installation on USB

Post by AmbroseJakis » Tue Nov 20, 2018 12:05 am

I am very new to LInux and have no idea how to fix this. Please be patient with me.

I should add I am installing it from another USB onto the larger 65GB one.

There are several things you might need to do. First, turn off secure boot in BIOS and make sure Windwoes starts. If it does, I think it's in the power options, where you need to turn off fast boot. Finally, you need to shutdown Windwoes completely. You should also check your BIOS for a fast boot option and disable it.

I think it's trying to tell you that you need to define the partition used for "/" (root).

In the pic w/o the error, e.g. select sda7, check "format", hit "Change" button (change what you use it for), and select "/",

Ahh, much better place to get help than Reddit. You'll get fixed up in no time.

First:
The first figure has a window in front and both do not show the entire disk drive. Please post readable images.

Note that the figures show a disk drive (sda), at first, to install the system and another (sdb) to install the boot loader.
Is that really what you want to do?
Install the system on a drive and boot loader in another force having the two drives always present.

Second:
Windows has a directory tree for each filesystem (partition). Each file system has your root directory, represented by "\" (backslash) and is represented by a drive letter (c:, d:, ...).

Linux provides a directory tree only and your root directory is represented by "/" (slash). The other file systems (partitions), when they are mounted, are hung in existing folders on "unique tree". There is no "drive letters".
These folders are called "mount points".

The filesystem (partition) that contains the "unique tree" is called a root file system. This is the partition that the system is installed.
It is necessary to set it so that the operating system installation can be performed.
