The boot drop down menu can be found in the server control panel under the Boot & Power tab.
The menu includes the following options:
- Boot from first HDD
- Boot from second HDD (if available)
- Boot from third HDD (if available)
- Boot from fourth HDD (if available)
- Boot to Selectel Boot Menu
- Boot to Rescue
Choose your boot option and then restart your server. Booting from the first or subsequent HDDs are the standard. By booting to the Boot Menu or Rescue, you can use different installers or tools for troubleshooting and restoring your system.
Selectel Boot Menu
The Selectel Boot Menu gives you access to installers for the most popular operating systems and software for troubleshooting and restoring your system. The boot menu is accessible from the KVM console:
All of the distros in the menu are net-install versions, so only the kernel and initrd are downloaded during installation. All other files can be downloaded from local or public repositories. This is why you will be asked to enter a repository to download from at the start of the installation. To simplify the installation, you can use our repository.
This kind of installation is the same as a disk installation. Several operating systems (which are marked SemiAUTO in the menu) offer semi-automated installations. For these options, the installer will prompt you for some key parameters (such as network settings, RAID/LVM settings, etc.).
Under Tools and Utilities, you’ll find an array of utility suites for troubleshooting and restoring your system.
Boot to Rescue
When you choose Boot to Rescue, a system is loaded from the RAM that doesn’t use the server’s local volumes. Boot to Rescue is recommended when general server access is lost or troubleshooting isn’t possible with the operating system’s tools. The rescue-system contains a wide array of tools for troubleshooting and restoring malfunctioning systems.
As soon as you choose Boot to Rescue, a login and password for the SSH connection to the server will be displayed in the control panel.
As soon as the server is restarted, it will be accessible via network connection and can be managed over SSH, which is much more convenient than a KVM console.
The rescue system will immediately try to find and connect RAID/LVM partitions. This lets you check and restore file systems, as well as restore data from backups. This can be done using supload, a utility designed for working with Selectel Cloud Storage.
The rescue system includes infiltrate-root, which makes it easier to change the root catalog (chroot) to gain direct access to the server’s data, reset the root password, edit configuration files, and more.
List of tools
- fdisk/gdisk, parted, tesеdisk - for working with disks and their partitions

- megacli/megactl - for working with LSI MegaRAID controllers
- cyberduck cli - for working with files over sftp, webdav, Amazon S3, and OpenStack Swift protocols
Boot to Windows PE
Window PE is a minimal Windows OS with limited services that launches from the server's memory. It is primarily used for troubleshooting, restoring, and deploying Windows. The operating system lets you:
- Create partitions and format disks
- Edit the system registry
- Launch utilities for troubleshooting and restoring Windows
Our Windows PE build includes the following utilities:
- BlueScreenView — tool for identifying the cause of a "blue screen of death"
- Regedit — registry editor
- 7-zip — file archiver
- CPU-Z — tool for gathering information on main system devices (processor, RAM, cache, motherboard)
- FAR Manager — console-based file manager
- CrystalDiskInfo — tool for analyzing hard disks
- IOMeter — tool for measuring the performance of I/O operations
- SMCIPMITool — tool for troubleshooting and configuring IPMI on SuperMicro servers
- Putty — popular SSH client for Windows
- Wireshark — network traffic analyzer
- WinMTR — program for troubleshooting network connections
- arcconf — program for managing Adaptec controllers
Launching Windows PE
You can download and launch Windows PE from the server control panel:
1) Open the Power & Boot tab.
2) From the template list, choose Boot to WinPE.
3) Click Reboot.
4) Click the console icon in the control panel.
The server console will open in the next browser window.
5) Open the terminal (the first icon to the left).
For the Windows PE console to properly work, you will have to configure the network.
1) Initialize the network setup:
2) Run the following command, filling in your server's parameters:
interface ip set address name=”Ethernet” static [server IP address] [subnet mask] [node]
3) Configure the DNS:
interface ip set dns "Ethernet” static 126.96.36.199
More detailed information can be found in the Windows PE official documentation.
