Your HP Pavilion won’t boot into Windows or you bought it without an operating system and need it ready to work? We install the system in your Pavilion completely, together with all drivers. Repair usually takes 1–3 working days.
In short: whether your HP Pavilion won’t start at all or you bought it without a system, we install Windows from scratch, select the version and language, load all drivers turnkey and check the licence key in the Pavilion’s BIOS, which you enter using the F9 or F10 key.
Our experience with HP Pavilion
We’ve installed the system in 4 HP Pavilion laptops. It’s HP’s most popular home series, often bought by pupils and students without a preinstalled system.

Pavilion — a series where the system needs installing particularly often
Pavilion is a laptop widely available in many configurations, so we receive both units without any system and those where Windows has become corrupted after years of daily use. In HP, BIOS launches with the F9 or F10 key, which makes it easier for us to check the licence key and configure system boot.
When you’re looking for help for your Pavilion
You find us after typing „HP Pavilion won’t start Windows”, „Pavilion system installation Warsaw” or „new Pavilion laptop without system what next”.
Symptoms of situations requiring system reinstallation
- Windows won’t start or loops during boot
- Laptop bought without an operating system
- System runs very slowly and unstably despite repair attempts
- Missing drivers after self-installing Windows
During installation we always ask about data on the drive — if there isn’t much, we transfer it free of charge before we proceed.
