Want to install new to existing installation

Keruskerfuerst · October 8, 2020, 1:53pm

I have an existing installation with GPT.
The only partition I want to keep is the /home partition.

But the installer of Manjaro 20.1.1 does not recognize my existing installation:
there is an GPT partition table and the installer does not find one.

In the future, when providing code/output, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text so that the output looks like this:
```
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
```
instead of like this:

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.

(as that makes our life much easier so you get helped more quickly and efficiently)
An output of parted --list would be more beneficial than blkid…

So basically you already have a Manajaro install on /dev/sda with GPT and want to reinstall Manjaro, but the installer doesn’t recognize the existing install automatically?

If my understanding is correct:

Did you install in UEFI mode last time? (GPT partitioning <> UEFI install)
what does “manual partitioning” show? (Screenshot please? Yeah: in German is fine…)

If incorrect:

Please correct me.

Keruskerfuerst · October 9, 2020, 10:38am

I have an existing installation and I want to keep /home.

The last installation was in UEFI and GPT.

Screenshot follows.

Keruskerfuerst · October 9, 2020, 2:50pm

I know, what I error was: missing installation in UEFI mode.
I had to select UEFI partition on the Manjaro USB to boot from.

~~So alles Okay denn?~~ So everything hunky-dory now?

Keruskerfuerst · October 9, 2020, 12:25pm

Now, the installation works.
Thanks!
