Failed Installation

Newbee-Forum.

It reminds me to my school-days when the Math Teacher
looked at me with a mixture of contempt and suspicion.

The deep night is the only time I can get online here
without broadband-restrictions.

When on online-installation I click on "something else."

Then a menu opens with the title >>INSTALL<<
The table shows in the upper left side:

/dev/sda Size Used System
free space 1MB
/dev/sda1 efi 104MB 52MB Win Boot Usage (?)

When I click on Forward (or Continue?) I receive the message

"No root file system is defined.
Please correct this from the partitioning menu."

Wow. What is the partitioning menu. Wait a second.
Momentary I am in the >> INSTALL << menu. Right?

Where could I find the partitioning menu. Should the >> Install <<
menu be the partitioning menu, what I presume to be very likely,
then - should I define the root file here?

I tried every possible option. Every. And I received the same
error-message (No Root File Sysem is defined) over and over again.
No matter what I crossed.

Beside the fact that I read the installation manual before
this experiment and learned most of the cryptic abbreviations
I must admit that I still miss 50 percent of understanding the
content of this table.

So I must conclude, or better, speculate, where I could find the
highly frustrating Partitioning menu. This is hard work, is it?

Thank you. For this night I will return to windows 10.

It would help to know what you are trying to install, at which stage you click on “something else”, and what other options exist. Also, can you clarify the term “online-installation”? You say you tried every option. What are those options? What table do you not understand?

FYI, installations include disk formatting, which includes a partitioning option. My feeling is that before you click “forward”, you have to select a partition to which the system will be installed, but I don’t have enough information to be certain.

Just a guess based on the limited information you provided. Because you see a "Something Else" option, likely that you are trying to install Ubuntu or one of its many derivatives. The sda1 and efi means you already have an installation using UEFI and have a windows install of some kind. Try reading the link below if you are using Ubuntu or trying to install it. If you are using a different Ubuntu derivative, the General Principles section should still apply.

It would be useful to post the full drive/partition output rather than just the efi.

"do something else" this is you doing everything in setting up your partitions, and to format or not to format and what filesystem format type and mount points.

that is why you got the message,

When I click on Forward (or Continue?) I receive the message "No root file system is defined. Please correct this from the partitioning menu."

double clicking on partition brings up an option, selecting a partition in the other dropdown boxes too give you an option, a little check box next to the partition selections for formatting. they all have to do with mount points, and formatting. you obviously skipped that part, hence the message.

Thank you BW-userx,
thanks Yancek and
thanks to Bernd Bausch,

I am grateful for your help.

I proceeded in the standard-way to install my Linux Mint 19.

For this purpose I am online and ckick on install. That is
described in the installation instructions and I acted accordingly.

BW-userx mentioned I have to double click the partitioning suggestions.

Wow. - Since I tried only single clicks on these options and nothing
happened, that sounds quite promising. I was not aware that one has to
> doubleclick < . I will try it again tomorrow. Fearless!

If you visit YouTube and search for "install Linux Mint," you will find many tutorials (some, of course, better than others). I think you will find it very helpful to watch a couple of them. Sometimes a picture is worth a thousand words.

Without knowing more about what you are trying to do, I hesitate to recommend a particular one.

I guess that “something else” refers to step 5 in the instructions https://linuxmint-installation-guide...t/install.html. As part of this step, you need to set up a partition, it seems. This partition needs at least 15GB. Again I guess: You either did not set up that partition, or there is not enough space on your disk. Perhaps an error message was issued at this point, which you didn’t see or ignored.

It’s unlikely that you have to double-click anywhere except in step 1.

Disclaimer: I have never attempted to install Mint 19.
