Windows 11 -asennus

Alkaen 799 kr

Need to install Windows 11 — as an upgrade from Windows 10, a clean reinstall after trouble or on a new SSD? Datorhjälp Lerum on Göteborgsvägen 3 has over 20 years of experience setting up Windows correctly from first boot to a ready desktop.

We check TPM, Secure Boot and hardware requirements, back up important files when needed and install with correct partitioning, drivers and basic security. You avoid getting stuck in BIOS menus or losing data because an update was interrupted halfway.

Workshop visits in Lerum, home visits in Floda, Gråbo, Partille, Gothenburg and Alingsås, or preparatory /fjarrsupport before you drop off the PC. Call 072-297 55 25 or book via /boka.

Professional Windows 11 installation in Lerum — fresh install, reinstall and upgrade.

When professional Windows 11 installation is needed

Windows 10 is approaching the end of security support, and many want to upgrade before it becomes urgent. Others receive a message that the PC "cannot run" Windows 11 even though TPM or Secure Boot only needs enabling in BIOS.

After virus, a broken update or years of accumulated software, a clean install can be the fastest path to a stable computer. Doing it without backup risks losing photos, documents and software licences.

Wrong partitioning, wrong Windows edition or missing drivers lead to black screen, no sound or Wi-Fi that does not work after installation. We handle the full chain so you can start using the computer right away.

Complete installation and configuration

We install Windows 11 with correct media, update drivers from the manufacturer, enable Windows Defender and basic security settings and install critical Windows updates before handover.

When upgrading from a valid Windows 10 licence we often keep activation without a new key. For reinstall or new disk we back up and restore files as agreed — and involve /dataaterstallning if anything is missing.

After installation we review what changed, which programs you need to reinstall and whether /windows-support or /langsam-dator can fine-tune the experience. You get a computer ready for daily use, not just a fresh wallpaper.

Signs it is time for Windows 11

  • Windows Update does not offer upgrade although the PC seems modern
  • Message that TPM 2.0 or Secure Boot is missing
  • Windows 10 feels unstable and /windows-support has not been enough
  • You want to switch to SSD and take the chance for a clean install

  • Installation from wrong USB media or corrupt ISO file
  • No backup before reinstall — files lost on format

  • Old software not compatible with Windows 11
  • 20+ years of experience
  • 5,000+ computers repaired

What to expect

Allow 2–4 hours for standard installation with basic drivers and updates. Restoring many gigabytes of files or reinstalling many programs can take a full day — we tell you in advance.

You will know whether hardware truly supports Windows 11 before we start. If not, we discuss alternatives: BIOS adjustment, limited upgrade or staying on Windows 10 with extra security until you replace the PC.

Why let us install Windows 11

A correct installation saves hours of troubleshooting afterwards — we do it daily in the Lerum workshop.

Pre-installation checks

TPM, Secure Boot, disk and licence are verified so you do not get stuck mid-setup.

Safe backup routine

We back up what matters before formatting and restore according to your wish list.

Drivers and updates

Wi-Fi, sound and display should work immediately — not after days of searching forums.

20+ years of experience

We have migrated customers through every Windows generation and know common pitfalls.

Local service

Drop off at Göteborgsvägen 3, get a home visit or combine with /fjarrsupport for preparation.

Prepare before installation

  • List programs and licence keys you need afterwards (Office, antivirus, etc.)
  • Back up files you cannot risk losing — we can double-check together
  • Have your Microsoft account password ready if the PC is linked to it
  • Plug in the laptop power adapter — installation must not be interrupted
  • Note if the PC is a work or school machine with special policy requirements

After installation — keep the system healthy

  • Complete Windows Update promptly in the first weeks after installation
  • Install programs only from trusted sources to avoid /virus-borttagning later
  • Enable automatic backup to external drive or cloud
  • Create a recovery image if space allows
  • Keep at least 15% free on the system drive for future updates

Upgrade or clean install?

Upgrading from Windows 10 often keeps programs and settings and is smoothest when the system is already stable. A clean install is recommended after serious virus, persistent trouble or when starting fresh on a new SSD.

We recommend the option that gives you the safest and fastest result — not the quickest for us. You learn pros, cons and how backup is handled before we start.
