There are situations where a fast OS reinstall isn't a convenience — it's a necessity. The server has been compromised to the point where recovery isn't worth attempting. You need to switch distributions — moving from CentOS to AlmaLinux after the end-of-life announcement, for instance. A test environment has served its purpose and a clean system is needed for the next experiment. A developer accidentally destroyed something critical in the root filesystem and starting over is faster than untangling the damage.
In the traditional dedicated server workflow, reinstalling the OS means filing a support ticket, waiting, coordinating, waiting again. An hour if you're lucky, several hours often enough. THE.Hosting has removed this barrier: reinstalling the operating system is done through the control panel independently, without involving technical support, in 10–20 minutes.
How Reinstallation Works
The process is initiated from the client area or through the IPMI server management interface. You select an operating system from the available catalog, confirm the action — and the server's management controller begins the procedure.
Technically, the server reboots into a dedicated service environment that formats the system partition and deploys the image of the selected operating system. The entire process takes 10 to 20 minutes depending on location and server configuration. After completion, the system reboots and the server is accessible via SSH with the new operating system installed.
No support involvement, no queue waiting. You started the process — fifteen minutes later you have a clean server with the OS you need.
Available Operating Systems
The operating system catalog for automatic installation on THE.Hosting dedicated servers covers all current server distributions:
Windows Server (2012 R2, 2016, 2019, 2022, 2025), Ubuntu (16.04, 18.04, 20.04, 22.04, 24.04), Debian (9, 10, 11, 12, 13), CentOS (6, 7, 8, 8 Stream, 9 Stream), AlmaLinux (8, 9, 10), Astra Linux (1.7.2, 1.7.3, 1.7.4, 1.7.5, 1.7.6), VMware ESXi (6), Proxmox VE (7).
Switching distributions works exactly the same as reinstalling the same one. Moving from Debian to AlmaLinux — select the image and start the installation. Trying Proxmox VE on the same hardware that ran CentOS — same process.
When Reinstallation Is Actually Needed
Server compromise. If a server has been breached and an attacker had root-level access to the system, restoring that system is risky. Malware can hide in places that are difficult to audit: the bootloader, the kernel, system libraries. The only guaranteed way to get a clean system is to reinstall from scratch.
Switching operating systems. The project has grown and requires a different stack. Client requirements changed. A control panel is needed that doesn't support the current distribution. Reinstallation with a different OS choice resolves this in 20 minutes.
Testing and experimentation. Configuring a new stack, learning an unfamiliar distribution, reproducing a problem in a clean environment — all of this is easier on a system without history. Reinstallation provides that clean slate immediately.
Accumulated technical debt. Servers that have been running for years accumulate chaos: packages nobody remembers installing, modified configuration files with no documentation, remnants of long-removed services. Sometimes reinstalling and redeploying everything through a configuration management system is cleaner than untangling the layers.
Upgrading to a new major version. Some distributions support in-place upgrades between major versions. Some don't. And even where they do, a clean reinstall often produces a cleaner result without artifacts from previous configurations.
What Is Preserved During Reinstallation
This is important to understand clearly: reinstalling the OS completely overwrites the system partition. All data, configurations, and software on the system partition are deleted. This is precisely what's needed to get a clean system.
Data on separate drives or RAID arrays that are not the system partition depends on the specific server configuration. Before reinstalling, back up everything important — databases, user data, configuration files.
A practical note: if you manage server configuration through Ansible, Puppet, or similar tools, reinstallation becomes a routine operation. Install a clean OS, run the automation script, and within 30–40 minutes the server is operational with a fully reproduced configuration.
Reinstallation via IPMI
In addition to the control panel, reinstallation is available through IPMI — the hardware-level server management interface. This matters when the operating system isn't booting or isn't reachable over the network: IPMI operates independently of OS state.
Through IPMI you can mount a virtual DVD drive with an OS image and install any operating system manually — including those not in the standard automatic installation catalog. This makes it possible to install specialized distributions or custom images.
Full IPMI/iKVM/iLO access is included as standard on all THE.Hosting dedicated servers for the entire rental period.
Control Panels During Reinstallation
After a new operating system is installed, control panels are also installed automatically — ISPmanager, cPanel, Plesk, DirectAdmin, Hestia, Webmin, Virtualmin, CloudPanel, FastPanel. This means changing the OS and changing the control panel happen in a single operation rather than sequentially.

FAQ
How long does OS reinstallation take on a dedicated server? Between 10 and 20 minutes depending on location and server configuration. After completion, the server is accessible via SSH with the new operating system.
Is support involvement required for OS reinstallation? No. Reinstallation is performed independently through the client area or IPMI without involving technical support.
Can the distribution be changed during reinstallation? Yes. Any available operating system from the catalog can be selected — switching distributions works exactly the same as reinstalling the same one.
Is data preserved during OS reinstallation? The system partition is completely overwritten. Data on separate drives depends on configuration. Back up all important data before reinstalling.
How many times can the OS be reinstalled? Without limit. Reinstallation is a standard operation available at any time through the client area.
