If you're merely trying to install a new version of Windows on your existing computer, skip this step. Insert the USB flash drive into a USB port on the computer.

If the computer turns on when you open its lid or move the mouse, you'll still need to restart it before proceeding. As soon as the computer's startup screen appears (the screen right after the computer shuts down and is beginning to restart), begin pressing the BIOS key. Your computer's BIOS key will vary depending on the manufacturer, but it will usually be one of the function keys (e.g., F2), Esc, or Del. You can check your computer's BIOS key online or in the manual that came with your computer. Many computers will flash a "Press [key] to enter setup" (or similar) message at the bottom of the screen as your computer is starting up. This is the key that you should press. If you miss your opportunity and the computer finishes the restart cycle, you'll need to restart it and try again. This section is usually in the Advanced or Advanced Options tab, but each BIOS menu is different. The "Boot Order" section will have a list of different startup locations, including your hard drive's name and your CD drive. Using the arrow keys, move the highlight bar down until it's covering the flash drive's name. On some computers, you'll instead select Removable Storage or Removable Drives (or something similarly titled). You'll usually do this by pressing the + key until the flash drive is at the top, but check the legend at the bottom or on the side of the BIOS screen to see if your controls are different. There's usually a key that you can press to do this, so check the legend to see what it is and then press it. You may have to press another key to confirm this decision. If your computer doesn't greet you with a "Press any key" screen and instead finishes the restart cycle, restart it again to boot from the flash drive. This will launch the Windows setup process.

Summary: Go to the computer on which you want to install Windows. Plug in your USB flash drive. Prompt the computer to restart. Rapidly press the computer's BIOS key. Find the "Boot Order" section. Select your flash drive's name. Move the flash drive to the top of the list. Save your changes and exit the BIOS. Restart your computer again if necessary.

Measure the opening in the door frame to determine the how large the replacement screen needs to be. Then, add 2in (5.1cm) to both the length and width measurements so you have enough room to secure the splines. You can purchase a full roll of screening if you plan on replacing multiple screens in multiple doors. On average, most screen doors come in 2 standard sizes, either 32in (81cm) or 36in (91cm) wide. They often measure to 80in (200cm) high. Center the screen as best as you can and aim to have the same amount of extra screen on each side. Keeping it centered ensures that 1 side is not too short when securing it to the frame. It's okay if the screen is not perfectly centered since you'll trim off the extra later on. Try to keep the screen as taught as possible. This looks the best and ensures no bugs get through the screen. Hold one end in place as your friend holds the other, and pull on the screen gently to get rid of any slack. If you're working alone, use pieces of tapes or clamps to hold the screen in place. After you lay the screen across the door frame, roll your spline roller across each groove of the door frame. This dents the screen slightly, making it easier to replace the spline. Doing this also helps prevent your screen from ripping during the process. If your splines are still flexible and do not have any cuts or dents, use the same pieces that secured the old screen. If the splines are cracked, old, dry, or damaged, throw them away and get new splines with the same diameter. If you are replacing the splines, cut them to the length of the grooves on the door frame. Line the spline up with the groove of the frame, and apply the roller to push the spline into the groove. Start at one corner and roll until you reach the opposite end. Then, secure the adjacent spline, working in an "L" shape. Do this until all 4 splines are pushed down and the screen is securely held in place. For a thorough hold, push the corners of the screen into place using a screwdriver. Once the screen is fastened to the frame, you can trim off any extra hanging along the edges. Line up your utility knife with the screen so it is about 116in (0.16cm) above the spline, pierce the screen with the tip of the knife, and drag the knife through the screen to cut it. Do this for all 4 sides and throw away the scraps of screen. To put the screen back in place, lift it up with both hands, and line up the bottom with the door track. Then, tilt the screen door until it is straight, and slide it into place. If you removed the door handle, screw it back into place with a flathead screwdriver. With a bit of maneuvering, you can easily put the door back on. If your door is on hinges, place the door back into your door frame, and place the hinge pins inside of the hinges. Tap them into place with the handle of a screwdriver.
Summary: Cut the screen at least 2in (5.1cm) wider than your door frame. Place the new screen across the door frame. Have a friend hold the screen in place so it stays taught. Roll the spline roller on the screen before inserting the splines. Reuse or replace your splines depending on their condition. Use a spline roller to press the spline and screen deeply into the groove. Cut away the extra screen using a utility knife. Replace your screen door and handle after you install the screen.
