Checksum

as if now in neospace we deliver 2 ways to verify the integrity of the downloaded file.

manual

you can manually download from the internet archive website and we showed you how to verify the checksums.

sums.7z

sums.7z contains all checksums in a single file. so if you extract the file make sure to have a zip file extractor or 7z it’s also free to download from here. next step is to verify using these tools , if you are on windows you can use these commands to just skip the headache of using a browser following command directly installs iso and verifies it :

Scripts to automate the process

Booting up

here are few ways to boot up the iso file:

Virtualization
Bootable USB drive

our following guide covers both of them, however, it is recommended to use a virtual machine for a quick look at the operating system before installing it on your computer, and we don’t recommend using a bootable USB drive for this purpose, it is because IF YOU ARE NEW IN LINUX AND FEAR TO TAKE RISKS WE CAN’T ASSURE YOU WILL SUCCEED. However, if you are confident and want to try it, you can follow the instructions below.

1. Virtualization

For virtualization, you can use tools like VirtualBox or VMware to create a virtual machine and boot from the ISO file. Here are some guides for setting up virtual machines with different operating systems: download a virtualization software like VirtualBox or VMware and follow the instructions to create a virtual machine and boot from the ISO file.

After that setup the virtual machine and boot from the ISO file.
