In addition to an empty 8 GB USB drive and ayou have to reserve about 30 minutes, perhaps longer, depending on your internet speed.
For clarity, it is possible to use a Mac to create a Windows 10 boot disk, but the process is quite technical and requires familiarity with Terminal, the Mac's command-line tool. It is not a process that I would recommend for the average user. I recently built my first gaming PC, and despite my mild comfort level with Terminal, I found a Windows computer still a safer and easier process.
Use the Microsoft Media Creation Tool
Microsoft has a special utility that you can use to download the Windows 10 system image (also known as ISO) and create your bootable USB drive.
1. Get started by going to this page and clicking on Download tool now .
2. After the download is complete, double-click the file named MediaCreationToolxxxx to execute it. (The last four digits of the file name indicate the version number of Windows 10. The file name is currently MediaCreationTool1909 but that will change if newer versions are released.) The file must be in your Downloads folder. .
3. Accept the Microsoft general terms and conditions, select Create installation media (USB stick, DVD or ISO file) for another PC and click Next .
4. You are asked to select the language, edition, and architecture that you want to use. By default, the tool uses the best options for the PC on which you create the boot disk. You can change any of the options by clearing the check box next to . Use the recommended options for this PC and use the drop-down lists. If you are not sure whether you need a 64-bit or a 32-bit architecture, select Both from the Architecture drop-down list.
5. Click Next when you have adjusted the options, leave USB stick selected and connect your USB drive to your computer. Select Next to continue.
6. Finally select the USB drive from the list. If you have more than one drive connected to your computer and you are not sure which one to choose, disconnect the additional drives. Select the correct station and click on Next .
The Microsoft tool takes care of the rest from there. Have a drink, take a walk or surf the internet while the tool does its work. Again, the process takes about 30 minutes, give or take, depending on your internet speed.
When the utility is ready, click Finish and remove the USB drive from your computer. From now on, if you need to install or reinstall Windows, you can connect the drive to your computer and restart. Your PC must boot from the disk so that you can install Windows.
If that does not happen, you must restart your computer in the BIOS firmware – usually done by pressing Esc, F2 or a similar key while the computer starts up – and the boot disk or "boot menu" to your flash drive. The process for each computer (or motherboard if you are building a gaming PC) will be different. I recommend that you consult your manual for instructions.
You can also use the media tool to upgrade from Windows 7 to Windows 10,. After installing Windows 10, . If reinstalling Windows 10 feels too much, use .
