I tried to install UBUNTO 20 as second UBUNTU system besides an existing UBUNTU 16 with GRUB. I tried to install a second GRUB on the third disk.

[Andreas Ohnsorge]

Hi,

I have an existing U16 system and wanted to install an U20 system on another disk in parallel to the first one. Intention was to get the existing grub loader modified to recognize both systems. Instead the installer tried to install a second grub loader on the second disc and failed.

Is there a desription how to do what I intended to do?

Thank you very much and

Kind regards

Andreas
