I installed it from the Calamaries Installer found in the LIVE USB ISO this time. And Instead of my primary hdd, I installed it on the other one. Works now, thanks for all of your support, dear nerds.
Absolutely not an expert or anything, but is it possible that the partition of your harddrive that you’re trying to install Debian on (hd0) is too small?
The original error actually makes it sound like there’s a partition on hda that’s bigger than hda itself.
Partition size wasn’t specified in any step of the setup. If that is the issue, Is there any way to fix it?
