Professional Windows & Mac OS Installation, Upgrade & Repair

Professional Operating System Installations

We perform complete operating system installations and upgrades, as well as standard software package installations on desktop computers, laptops, and servers. We also can transfer data from your old computer system to a new operating system installation once completed, and depending on the situation, we may be able to transfer certain applications without needing the original installation media.

We recommend clean operating system installs on most equipment to avoid migrating any underlying problems from the original installation. Our technicians ensure all drivers, updates, and settings are properly configured for optimal performance.

Repair Microsoft Windows OS Without Data Loss

Repairing a Windows installation without losing data is possible through several methods. One of the most effective approaches is using the Startup Repair tool, which can fix common issues preventing Windows from booting properly. To access this, restart your PC and press the F8 key (or the equivalent) during startup to enter the Advanced Boot Options. From there, choose Repair Your Computer and then select Startup Repair.

Another method is to perform an in-place upgrade (also known as a repair install), which involves using the Windows Installation Media (USB or DVD). This process installs a fresh copy of Windows over your existing installation while preserving your files, settings, and installed programs. To do this, run the setup from the installation media, choose Upgrade, and follow the on-screen instructions. This method is ideal for fixing system files or resolving stability issues without the need to format or reinstall Windows, ensuring no data loss.

Always make sure to back up important data before proceeding with any repair process, just as a precaution.

Upgrade Your Old Windows to a Newer Version

Upgrading an old computer to Windows 11 or 12 involves several key steps to ensure compatibility and a smooth transition. First, verify if your system meets the minimum requirements, such as a compatible 64-bit processor, 4GB of RAM, 64GB of storage, and TPM 2.0 support. You can use the PC Health Check tool from Microsoft to check compatibility. If your PC meets the requirements, the next step is to back up your important files.

You can then proceed with the upgrade by either using Windows Update (if available) or downloading the Windows Installation Assistant from Microsoft’s website. If you prefer a clean installation, you can create a bootable USB drive with the Windows Media Creation Tool and perform a fresh installation. During the upgrade, the system will retain your files and apps (unless you choose a clean install), but it's always wise to back up your data beforehand.

How to Get a Newer Version of Windows

To get a newer version of Windows, such as Windows 11 or 12, you have several options. First, check if your device is eligible for an upgrade by reviewing the system requirements. If your PC is eligible, the easiest way is through Windows Update – go to Settings > Update & Security > Windows Update and click Check for updates. If an upgrade is available, it will be listed.

If you don’t see the update, you can use the Windows Installation Assistant from Microsoft’s official website to manually initiate the upgrade. Alternatively, use the Media Creation Tool to create a bootable USB drive and perform a clean installation of the latest Windows version. In some cases, you might need to purchase a new license. Always back up your data before upgrading.
