Usage

Tip

All features can be used on both Linux and Windows.

on Linux, execute bash reinstall.sh

on Windows, execute reinstall.bat

Feature 1: Install Linux

If no version number is entered, the latest version will be installed.
Does not include a boot partition (except for Fedora), nor a swap partition, maximizing disk space utilization.
When installing on a virtual machine, it will automatically select a official limmed-down kernel.
During the initial login, you may receive a password error prompt; just wait a moment and it should be resolved.

Tip

When installing Debian / Kali, x86 architectures can monitor the installation progress through VNC in the background, while ARM architectures can use the serial console.

When installing other systems, can monitor the progress through various methods (SSH, HTTP 80 port, VNC in the background, serial console).

Important

To install Red Hat, you need to provide the qcow2 image link obtained from the following website.
