One-click reinstallation script

[中文](README.md) | English

## Highlights

- Installing using official cloud images (Cloud Image) allows bypassing the [memory requirements](https://access.redhat.com/articles/rhel-limits#minimum-required-memory-3) of traditional network installations, resulting in faster installation speed.
- Compatible with 512M + 5G small servers and supports installing Alpine on 256M small servers.
- Compatible with all network conditions, including dynamic/static IPv4/IPv6 and pure IPv4/IPv6.
- Supports installing Windows using the official ISO.
- Supports reinstalling Windows as Linux or Windows itself.
- Supports BIOS, EFI, ARM.
- The original system partition supports LVM, Btrfs.
- Supports installing Alpine, Arch, openSUSE, Gentoo, and can also install these systems from them.
- Progress of DD and cloud image installation can be viewed through SSH, browser, serial console, and web panel VNC.
- The script does not include third-party links or homemade packages; all resources are obtained in real-time from the source site.
- Includes many comments.

## Usage

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

- The parameter --ci indicates forced usage of the cloud image for installation.
- Machines with static IP installing CentOS, Alma, Rocky, Fedora, Ubuntu must include the parameter `--ci`.
- If it is uncertain whether the machine has a static or dynamic IP, you can also add the parameter `--ci`.

```bash
bash reinstall.sh centos   7|8|9  (8|9 for the stream version)
                  alma     8|9
                  rocky    8|9
                  fedora   38|39
                  debian   10|11|12
                  ubuntu   20.04|22.04
                  opensuse 15.5|tumbleweed
                  alpine   3.16|3.17|3.18|3.19
                  arch
                  gentoo

                  If no version number is entered, the latest version will be installed.
```

Parameters:

```bash
--ci              Force the use of the cloud image
```

### Feature 2: DD

- Supports gzip, xz formats.
- For machines with static IP, DD Windows, and the script will automatically configure the IP.

```bash
bash reinstall.sh dd --img https://example.com/xxx.xz
```

### Feature 3: Reboot to Alpine Rescue System (Live OS)

- Can be connected via SSH to perform manual DD, modify partitions, manually install Arch / Gentoo, etc.
- If the disk content is not modified, rebooting again will return to the original system.

```bash
bash reinstall.sh alpine --hold=1
```

### Feature 4: Reboot to netboot.xyz

- Can install [more systems](https://github.com/netbootxyz/netboot.xyz?tab=readme-ov-file#what-operating-systems-are-currently-available-on-netbootxyz) using web panel VNC.

```bash
bash reinstall.sh netboot.xyz
```

![netboot.xyz](https://netboot.xyz/images/netboot.xyz.gif)

### Feature 5: Install Windows ISO

- Pay attention to the quotation marks around the parameters

```bash
bash reinstall.sh windows \
     --iso 'https://drive.massgrave.dev/en-us_windows_10_enterprise_ltsc_2021_x64_dvd_d289cf96.iso' \
     --image-name 'Windows 10 Enterprise LTSC 2021'
```

`--image-name` Specify the image to install, case-insensitive, for example:

```text
Windows 7 Ultimate
Windows 10 Enterprise LTSC 2021
Windows 11 Pro
Windows Server 2022 SERVERDATACENTER
```

Use `Dism++` File menu > Open Image File, select the iso to be installed to get the image name.

3. Vista (Server 2008) and 32-bit systems may lack drivers.
4. For EFI machines without CSM enabled, Windows 7 (Server 2008 R2) cannot be installed.
5. If the machine has a static IP, the IP will be automatically set after installation.
6. Can bypass Windows 11 hardware restrictions.
7. Supports Windows 11 on ARM, exclusively for Hyper-V (Azure), not compatible with KVM (Oracle Cloud).
8. The process `wsappx` will occupy CPU for a long time after installing the image `zh-cn_windows_10_enterprise_ltsc_2021_x64_dvd_033b7312.iso`.

   This is an issue with the image, and the solution is to install the `VCLibs` library.
