How To Install And Run Windows 10 From a USB Drive.



Install an operating system on a bootable USB drive, and you can take your whole computer with you – almost. Granted, you still need a PC or laptop to plug it into, but it is a great way to carry your favorite programs and essential data wherever you go. You can access them on someone else’s PC, even if they’re not willing to share their login credentials with you.

Install Windows on a USB drive Despite its power, Windows actually has a fairly conservative system requirements and it will happily live on drives as small as 16GB (for the 32-bit version) or 32GB (for the 64-bit edition).

How To Install And Run Windows 10 From a USB Drive.

Step 1: At first, open Windows10 page and download Windows 10 tools by clicking on ‘Download tool now’.


Step 2: When asked whether you want to save or run the linked file, click Run and, once it’s launched, click through the wizard, accepting all the defaults until it asks ‘What do you want to do?’. Click the radio button beside ‘Create installation media (USB flash drive, DVD or ISO file) for another PC’, followed by Next.

Step 3: Leave ‘Use the recommended options for this PC’ ticked and click Next again, then select ‘ISO file’ and click Next. Select your Downloads folder as the destination for the download and click Save.

Note- Tell the Windows 10 Setup tool you’re creating media for another PC.

Step 4: You’ve downloaded an image of the Windows installation disc, now you’ll need a copy of WinToUSB so you can write it to your USB stick.

Step 5: Launch WinToUSB, confirm it to make changes to your system, then click the folder icon to the right of the Image File box.


Step 6: Navigate to your Downloads folder and select the installation file (Windows.iso). Select the version of Windows for which you have a license and click Next.

Step 7: On the following page, select the USB drive on which you want to install Windows from the drop-down menu.

Note- Be sure to select the Windows Installation files you have a license for.

Step 8: WinToUSB will ask you to select a partition scheme. Leave the default selection as it is and click Yes, and the tool will format your USB drive. This will remove all its data, so make sure you back up anything you want to keep.


Step 9: When the format completes, you’ll be asked to select an installation mode. Select Legacy and click Next. WinToUSB will then start installing Windows on your stick.

Step 10: The time this takes to complete will depend on the speed of both your PC and the USB stick – in our case, it was over 30 minutes. When it’s finished, leave the stick plugged in and reboot, making sure your computer starts from the external drive.

So these are the following steps by which you can run Windows 10 from a USB drive.


Booting From External Drive.



Booting from an external drive You’ll need to configure your PC to stop it launching from your regular hard drive by tweaking the settings in your PC’s BIOS (Basic Input Output System) or UEFI (Unified Extensible Firmware Interface).

You can access these by pressing a shortcut key while your PC reboots – often, it’s F10, but the designated key will normally be displayed briefly during booting. If this doesn’t happen, check your manual. 

Navigate the menus until you find an option for setting the boot order, and rearrange the options so that USB has priority, then save the settings and exit. Your PC will reboot, this time launching from the USB drive. 

If you reboot without the drive plugged in, it will resort to the second, third and lower priority options, eventually finding your internal drive again and launching Windows as usual.
