Link not working? Let us know
Debian is a free, open-source operating system developed by the Debian Project. The current release is Debian 13 "trixie"; the default download is a small network-install (netinst) image for 64-bit PCs, and a desktop install needs at least 1 GB of RAM and 10 GB of disk.
Debian is the base for many other distributions, including Ubuntu, and is known for careful, stable releases. It suits servers, older PCs and anyone who prefers reliability over the newest version of every app.
What you download
The main download link gives you a netinst image for 64-bit PCs (amd64), for example debian-13.7.0-amd64-netinst.iso. It contains just enough to start the installer and fetches the rest from the internet, so a network connection is needed during setup. Debian also publishes live images and installers for other architectures on the same site.
The installer ISOs are hybrid images: you can write them directly to a USB stick, or burn them to a DVD.
Hardware requirements
Debian’s installation guide recommends at least 512 MB of RAM (1 GB recommended) and 4 GB of disk for a system without a desktop. With a desktop, plan for at least 1 GB of RAM (2 GB recommended) and 10 GB of disk.
Verify the image
Next to the ISO you will find SHA512SUMS and a signature file. Check the signature, then compare the SHA512 sum of your download with the listed value; Debian’s ISO Verification Guide explains the steps.
Writing the USB
Any tool that writes images byte for byte works. On Windows, Rufus is a simple option; Ventoy is handy if you keep Debian next to other installers on one stick. During installation you choose a desktop (GNOME, KDE Plasma, Xfce and others) or none at all. Back up existing data first, especially when installing next to another system.
Pros
- Very stable, carefully tested releases
- Small netinst download
- Choice of desktop during installation
Cons
- Software versions are older than in fast-moving distributions
- The installer is less polished than some alternatives
Frequently Asked Questions
Do I need internet access to install Debian from the netinst image?
Yes. The netinst image only contains the installer and a minimal system; the rest of the packages are downloaded during installation.
Can I write the Debian ISO to a USB stick?
Yes. Debian installer ISOs are hybrid images that can be written directly to USB sticks or burned to CD/DVD/BD media.
