[SOLVED] First time installing linux (Debian). Got this error. Please help
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?
At some point, the installation should ask you the driver on which it should be installed and also how the driver should be interacted with; i.e full wipe and then installation or only specified partitions. You specified elsewhere that you don't intend to dual-boot. Hence, selecting the correct drive and following the instructions for full wipe + installation (which should be regular/default installation) should have been sufficient.
Considering that it has a 2020 firmware, and is built by "to be filled by OEM", my completely unfounded wild guess is that the system firmware has broken legacy boot support. From other posts here, I gather you're using a legacy dos-style partition table. Try installing again with GPT/EFI instead.
