Out of curiosity, how come this was marked as solved?
Not sure if you noticed but this is an old topic that was marked solved even before you posted. That’s one of the reasons why we keep telling people to open their very own topics and post all their details in that new one. Makes things a lot clearer. If you think a lot of the information is in the old topic, then just link to it from your new one.
Please add details like the exact commands used to prepare the files and version of GParted you use as this might make a difference. As well post if you boot in UEFI or legacy BIOS mode and if it’s a VM setup or on hardware.
