Booting from a USB on Windows 10 never feels super straightforward at first, especially because every manufacturer seems to have its own quirks with key prompts or BIOS layouts. But once you get the hang of it, it’s pretty useful — whether you’re trying to do a fresh install, run a diagnostic, or just test out Linux without messing with your main drive. The main thing is, you’ve got to prepare the right bootable USB, then access the right menu at startup. And yes, Windows definitely has a habit of making this more complicated than it needs to be.
How to Boot from USB Windows 10
These steps will help you get your computer to boot from a USB drive. It’s not magic, but it does require a few key presses and some prep work on the USB side. Once you’re done, your system will load whatever setup or recovery tool you’ve put on that drive — pretty handy if something’s busted or you’re doing a fresh install. And, honestly, once it’s set up properly, it’s mostly just a matter of timing and patience.
Insert your USB drive and get ready to restart
Think of this as the crucial step — plug in your bootable USB (preferably at least 8GB, formatted to FAT32 — tools like Rufus make this mostly painless).Once it’s in, save anything you need because, yep, this process often involves rebooting and possibly formatting the drive if it’s not already prepared. Keep that USB tucked in, because from here, it’s all about the next restart.
Jump into the BIOS or Boot Menu
The tricky part is timing. As soon as the computer shuts down and starts back up, you’ll need to hit the right key to access either the BIOS setup or the boot menu. Common keys are F12, F2, ESC, or DEL. If you’re lucky, your startup screen will show which key to press — but if not, a quick Google for your PC model + “boot menu key” will usually give you the answer. Sometimes pressing the key repeatedly right after powering on works better than holding it down.
Select the USB drive as your boot option
Once you’re in the menu, navigate with arrow keys and pick the USB device. Usually, it’ll be named after the make or just listed as USB or Removable Storage. Hit Enter, and if things go right, your PC will start booting from that drive instead of your hard disk. Expect to see some splash screens or loading prompts from the setup or diagnostic environment on your USB. Sometimes it doesn’t work the first time, so don’t be surprised if you need to repeat the process or try a different port.
Tips for making this work smoother
- Always double-check your BIOS/UEFI settings — look for Boot Order or Boot Priority and make sure Secure Boot is disabled if you’re using a non-Windows ISO. Otherwise, it might skip the USB entirely.
- If your USB isn’t showing up, try a different port. Preferably, use a USB 2.0 port — some systems have issues with USB 3.0 during boot.
- Keep your laptop or desktop plugged in, especially during BIOS changes or OS installs — power cuts during this process can corrupt your firmware or drive.
- Sometimes, it’s easier to jump into Windows Settings — go to Update & Security > Recovery > Advanced Startup > Restart Now. From there, pick Use a Device and select the USB, which bypasses fiddling with the boot menu keys. It’s a kinda hidden way to get there.
FAQs About Booting from USB Windows 10
What if my PC doesn’t see the USB at all?
Check if the USB is properly formatted and bootable. Sometimes, creating the drive with Rufus or the Media Creation Tool helps. Also, try different USB ports—preferably USB 2.0 nowadays. And verify in BIOS/UEFI that Secure Boot is turned off and Legacy Boot (if applicable) is enabled.
How do I figure out the right key for the boot menu?
It varies by brand—Dell, HP, Asus, etc., usually show a message like “Press F12 for Boot Menu” during startup. If it’s not clear, a quick web search with your model name will usually crack it.
Can I just use any USB stick for this?
Pretty much no. Not every USB will boot properly. Make sure it’s at least 8GB, formatted correctly, and that you’ve made it bootable with Rufus or Windows Media Creation Tool. Otherwise, the PC won’t recognize it as a boot device.
How do I create a bootable USB drive anyway?
Tools like Rufus (free and easy) or the official Windows Media Creation Tool do the job. Rufus lets you select your ISO, format the USB, and make it bootable with a few clicks. Just remember, this wipes the drive, so back up anything important first.
Does booting from USB delete my files?
Not unless you go ahead and install Windows or wipe the disk. Booting from a USB itself is just a way to run an OS or recovery tool from that drive, not a destructive action. But, always be careful if you proceed to install or wipe disks afterward.
Summary
- Prepare your USB with a bootable OS or recovery image using Rufus or similar.
- Insert the USB, then restart your machine.
- Use the appropriate key (often F12 or ESC) to access the boot menu.
- Select your USB from the options and hit Enter.
Wrap-up
Getting into boot from USB mode in Windows 10 can be a pain in the neck, especially because every maker has a different way of doing it.

And yeah, it’s kind of weird how these steps vary or sometimes don’t work the first time, but with patience, you’ll get it. Fingers crossed this helps someone cut down the hassle a bit.
