Error installing Q4OS 6.2

pzeta59 · 2025-10-25 20:05

Hi, this is the first I post to the forum.
I tryed to install Q4OS 6.2 Plasma on an existing partition of my PC (HP Z220 workstation 240 GB SSD, 16 GB RAM) and I get an error in the installer. On this SSD I have 4 partition: 2 for Windows 10, a partition with working Q4OS 5.8 and another partition where I installed some time ago Q4OS 6.1.

I first tryed to substitute a partition, then, after the error, I format the partition and tryed again to install, but with the same error.

This is the information a get from calamares:

Are you trying to replace a partition ?

Please run:
$ lsblk
$ sudo blkid
and post back the output.

Since Calamares crashed, I would suggest to check first your install media (USB stick).
Please refer to the short description here.

pzeta59 · 2025-10-27 21:02

I create a new install media on a different USB stick using Rufus and the problem was solved.

I think it wasn't a USB stick problem, but the fact that this USB stick was created using Ventoy, with other ISO files on it.
