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.
I dont know how you flashed the usb, but it seems like the installer is damaged. Try redownloading the iso, check the file hash, flash the usb drive with balena etcher and reinstall.
Did you change the partition layout in the installer?
Okay, I will try again with a live-boot USB this time
edit: Thanks so much! This finally worked
This error (hd0) is typical of legacy (BIOS) booting end happens solely because of the MBR. GRUB2 is hit or miss with MBR.
If you’re not planning on dual booting with Windows XP/Vista/7, I’d recommend going to your motherboard settings and changing the boot mode to UEFI.
Then reinstall Debian. That will automatically sort things out :)
I thought the only reason to still use GRUB2 was its MBR support.
We really should be moving on at this point.
what’s next?
