reinstall is a one-click VPS OS reinstallation script for low-spec instances.

- One-click reinstall to Linux, supporting 20 common distributions.

- One-click reinstall to Windows using official original ISO files rather than custom images, with automatic ISO link lookup, automatic installation, and automatic installation of VirtIO and other public-cloud drivers.

- Supports reinstalling in any direction: Linux to Linux, Linux to Windows, Windows to Windows, and Windows to Linux.

- Automatically sets IP configuration and intelligently handles static and dynamic addresses, `/32`, `/128`, gateways outside the subnet, pure IPv6, and IPv4/IPv6 on different network interfaces.

- Requires less memory than official netboot, making it suitable for low-spec VPS instances.

- Identifies disks throughout the process by partition-table IDs to ensure the wrong disk is not written.

- Supports BIOS and EFI boot, as well as ARM servers.

- Contains no custom packages; all resources are fetched from mirrors in real time.

Additional functions include one-click DD of a Raw image to disk, booting Alpine Live OS as an in-memory system, and booting netboot.xyz. It can be downloaded from GitHub or cnb.cool. On Windows, disable Windows Defender real-time protection before use, as it can prevent `certutil` from downloading files.

The lowest listed target requirement is 256 MB of memory and 1 GB of disk space, depending on the target system. The script theoretically supports dedicated servers and PCs, but is not recommended when IPMI or a USB drive is available. It does not support OpenVZ or LXC virtual machines.
