One-Click system reinstallation script for VPS 中文

• One-click reinstallation to Linux: Supports 19 common distributions.
• One-click reinstallation to Windows: Uses the official original ISO instead of custom images. The script can automatically fetch the ISO link and installs public cloud drivers like VirtIO.
• Supports reinstallation in any direction, i.e., Linux to Linux, Linux to Windows, Windows to Windows, Windows to Linux
• Automatically configures IP and intelligently sets it as static or dynamic. Supports /32, /128, gateway outside subnet, IPv6 only, IPv4/IPv6 on different NIC
• Specially optimized for low-spec servers, requires less memory than the official netboot
• Uses partition table ID to identify hard drives throughout the process, ensuring no wrong disk is written
• Supports BIOS and EFI boot, and ARM Server
• No homemades image included, all resources are obtained in real-time from mirror sites

If this helped you, you can buy me a milk tea.

[!WARNING]

In theory it also supports dedicated servers and PCs

but if you can use IPMI or a USB drive, this script is not recommended.

[!WARNING]

❌ This script does not support OpenVZ or LXC virtual machines.

Please use https://github.com/LloydAsp/OsMutation instead.

An ISO usually contains multiple system editions, such as Home and Pro. Therefore, you need to use --image-name to specify the system edition (image name) to install, case-insensitive.

You can use tools like DISM, DISM++, or Wimlib to query the image names included in the ISO.

Commonly used image names include:

Windows 7 Ultimate
Windows 11 Pro
Windows 11 Enterprise LTSC 2024
Windows Server 2025 SERVERDATACENTER

Open File menu > Open Image File, select the iso to be installed to get the image name (full system name), and all available image names are installable.

[!WARNING] Vista (Server 2008) and 32-bit systems may lack drivers.

[!WARNING]

For Windows 7 (Server 2008 R2) installation:

1. EFI-boot machines must enable CSM.

2. On Hyper-V (Azure), select Generation 1 VM. https://learn.microsoft.com/windows-server/virtualization/hyper-v/plan/should-i-create-a-generation-1-or-2-virtual-machine-in-hyper-v

[!WARNING]

In the Chinese version of Windows 10 LTSC 2021 ISO zh-cn_windows_10_enterprise_ltsc_2021_x64_dvd_033b7312.iso, the wsappx process may indefinitely consume CPU resources.

The solution is to update the system patches or manually install the VCLibs library https://www.google.com/search?q=ltsc+wsappx.

[!WARNING]

When installing Windows ISOs released in May 2022 or later on GCP, the system may repeatedly reboot during the Windows installation (PE) stage. You can resolve this issue using one of the following two methods:

1. Add the --force-boot-mode bios parameter. The script will install Windows in BIOS boot + MBR partition table mode.

   (Optional) After installation, you can convert it to EFI boot + GPT partition table using the command MBR2GPT /convert /allowFullOS.

2. Create a custom RAW image and install it via DD.

Most ARM machines support installing latest Windows 11.

During the installation process, you might encounter a black screen, and the serial console may display ConvertPages: failed to find range, but neither issue affects the installation.

According to the Law of Bug Conservation, fixing old bugs often introduces new ones.

If a new bug occurs, try using an older version to see if it works.

Go to https://github.com/bin456789/reinstall/commits/main and find the old version’s commit_id on the right side.

commit_id=xxxxxxx
curl -O https://raw.githubusercontent.com/bin456789/reinstall/$commit_id/reinstall.sh || wget -O ${_##*/} $_
sed -i "/^confhome.*main$/s/main/$commit_id/" reinstall.sh
bash reinstall.sh ...

1. Fork this repository.
2. Modify the confhome and confhome_cn at the beginning of reinstall.sh and reinstall.bat.
3. Make changes to the other code.
