How to download Windows 11 installer to a USB
Let me walk you through exactly how to download the Windows 11 installer to a USB using the DiskPart command-line tool and a manual file copy.
The idea is pretty straightforward: you use a Windows command called DiskPart to completely clean and prepare your USB drive, then you manually copy all the Windows installation files from an ISO file onto that USB drive. Once the files are copied over, the USB becomes bootable and ready to install Windows 11.
How to download the Windows 11 installer to a USB:
Step 1: Download the Windows 11 ISO
Step 2: Open Command Prompt as Administrator
Step 3: Use DiskPart to Prepare the USB Drive
Run these commands one at a time, pressing Enter after each line:
cmd
diskpart
list disk
Step 4: Mount the Windows 11 ISO
You need to access the files inside the ISO. Windows can mount ISO files natively:
- Navigate to the ISO file you downloaded
- Right-click the file and select Mount
- Windows will create a virtual DVD drive (like "D:" or "E:") containing all the Windows installation files
Step 5: Copy Files to the USB
- Open the mounted ISO drive in File Explorer. Select all files and folders inside it, then copy and paste them to your USB drive.
Step 6: Make the USB Bootable
- If you used FAT32, the drive should already be bootable. If you used NTFS, the bootsect command above makes it bootable. Either way, your USB is now ready to install Windows 11.
I used this method to download windows 11 onto the usb, using my MSI Apache pro laptop. My plan was to use the usb to reset my other laptop (my old HP laptop), but I ran into quite a frustrating issue. Let me start from the beginning.:
My hp laptop was my daily laptop before I got my Apache pro. I bought the Apache pro a little over a year ago, and proceeded to set it up, and it has been my daily laptop ever since. I was deep cleaning and sorting through all of my things in my closet, hoping to downsize before I move. I found my old hp laptop and I immediately just stopped everything I was doing, and booted it up to explore my old files and such (Ahaha, ADHD much.?). Once booted, I realized that I had no idea what my login password was.
so I restarted it, booting into recovery mode. I planned to reset it since I didn’t know my login password. I ran into another issue. My drive was BitLocker protected. Okay… cool. I was able to use the USB that I had downloaded the windows 11 iso onto, and I plugged it into the hp laptop.
I went into my bios and I configured the boot order, saved, and restarted the laptop. I was able to boot up into the recovery menu using the usb. I used cmd prompt and I just straight up erased my C: drive 🤣, and I created a new drive, labeled D:. I restarted the laptop once more, using the USB to boot into the blue windows installation screen. Here’s where I ran into another problem.
since I decided to just up and delete my entire C: drive using disk part — without using my brain cells, obviously. I have spent a good 5 solid days trying to fix this problem, putting in over 40 hours of active debugging work. I’ve not made any progress.
I should done my research before I just erased my entire C: drive, because I didn’t realize that doing so would erase all of my data (which is fine), including the windows files (this is also fine), as well as ALL OF MY DRIVERS (this is not fine.!).!
I’m so frustrated with it.! I have wracked all of my brain cells. I’ve searched Google endlessly, I’ve asked Gemini and chat-gpt, but they haven’t been very helpful. I turned to copilot, alas.! A somewhat competent AI, it suggested that I use my Apache pro to go to the HP website and download the drivers for my hp laptop and put them onto the usb. So I did.
I popped the usb back into the hp laptop once I downloaded the drivers from the HP website, but to no avail. No changes.
I have no mouse, no keyboard, no sound, no voice assistant,nothing. I have absolutely jack diddly squat. At this point, I decided that maybe it’s time to turn to the Microsoft community for help.
what do you suggest.? What should I do.?
