Here’s a general flow that works for many PCs:

1. Back up important files to external storage.
2. Have your product key and Wi‑Fi info handy.
3. Create the bootable USB using the publisher’s media tool or a trusted utility (8 GB+).
4. Insert the USB, power on, and open the one‑time boot menu (key varies by device) to select the USB drive.
5. Follow the prompts to choose upgrade or custom install, select the target drive/partition, and continue.

• Tip: Retailer‑sold install/repair USBs are designed to boot right away.
• Firmware settings (UEFI vs. Legacy) and steps can vary by model, so review on‑screen guidance carefully.

Many users create installation media at no cost, then activate with a valid license:

1. Download the official installation tool or ISO from the software publisher’s site.
2. Use it to write a bootable image to a USB drive (8 GB+).
3. Install the OS and activate with a license key you already own or purchase separately.

• The download and creation tool are typically free, but activation generally requires a paid license.
• If you prefer ready‑to‑use media, retailers also offer installer and recovery USBs.

Availability, editions, and terms vary by region, so review the publisher’s instructions before you begin.

You can either buy one or make your own:

1. Purchase a ready‑to‑boot installer or repair USB from a trusted retailer. Check details like edition (Home/Pro), 64‑bit, language, and whether a license key is included.
2. Create your own using the publisher’s media tool and a blank USB drive.

• Verify compatibility notes (UEFI vs. Legacy support) and minimum system requirements.
• Recovery/repair USBs help fix or reinstall; installer USBs focus on fresh setup.
• Choose delivery or store pickup as available.

Review product descriptions closely to match your device and needs.

There are reputable no‑cost utilities that can write an ISO to USB and make it bootable.

• When possible, use the OS publisher’s own media creation tool for added compatibility.
• If using a third‑party utility, download from the developer’s official page and review the license (freeware vs. open‑source).
• Verify checksums when provided, run tools with administrator rights, and decline any optional add‑ons you don’t want.
• Back up data before modifying disks and safely eject the USB when done.

Features and reliability vary by tool and system, so results can differ.

It depends on the choices you make during setup:

• Upgrade/keep files: Some installers let you keep personal files; apps and settings may still change.
• Custom/clean install: Deleting or formatting partitions removes files, apps, and settings on that drive.
• Repair/recovery media: Can fix boot issues or reinstall the OS; certain actions may overwrite system files and apps.

Always back up important data first. Read each screen carefully, select the correct drive/partition, and confirm you have your license key and passwords. Results can vary by device and installer.
