Converting iso to USB is very easy.

But have you ever thought, that after converting it you also need to restore it back to its normal state?


The same thing happened to me, I thought never of it.

But Last week, when I used my bootable pen drive on other devices it wasn’t working properly.

I don’t know why. It was only showing the error “USB not detected“.

Then I searched on the internet and realized that I need to restore my USB drive to the original state back and make it normal.

And I got my answer, which I am going to show you.

Let’s see How it works…

How to Convert Bootable USB to Normal

In this tutorial, I will show you 3 Methods to restore USB drive to original state for Windows 10, Mac OS & other third-party tools.

So Let’s get started.

Method 1: Format Bootable USB in Windows 10

This is the most common step taken by every user to restore their USB drive back to the normal state. Let’s see how it works…

1. Click on Start and Search for “This PC” & Press Enter.

2. Now select the bootable USB Flash Drive. Right Click on it and Select Format

3. Now select the File system as NTFS or FAT32 and Allocation unit size (as per your need). Also, you can also click on Restore device defaults.

Finally Click on Start, then OK and Close.

And your USB disk is formatted now.

You can also perform this same using Disk Management.

Unboot USB Using Disk Management System

Just follow these steps…

1. Click on Start and Search for “diskmgmt.msc” & Press Enter.

2. Now locate your bootable USB drive. Right Click on it and Select option Format

3. Select the Filesystem and allocation unit size as Default. And Click OK.

This method is a quick fix but does not work always in making USB drive Unbootable. And that’s why we use Diskpart cmd.

Method 2: Convert Bootable USB to Normal using Diskpart CMD

I hope you have already inserted your bootable USB drive in your PC before performing these steps…

1. Click on Start and Search for “CMD” & Press Enter. And the Command Prompt dialog box will open up.

2. Now type “diskpart” command & Press Enter. And it will open up DISKPART

3. Now type “disk list” & Press Enter. It will list all your hard drives present on your Computer.


4. Now type “select disk 1” & Press Enter. Here you have to select the right bootable USB device, like in my case disk 1 of 16gb is for USB.

Note:- Please be careful while selecting the disk as you may end up losing your data by selecting the wrong hard disk.

Now the major steps to convert the bootable USB to normal one.

5. Now type the “clean” command & Press Enter. And it will wipe/clean all your Bios boot files present on USB.

6. Next type “create partition primary” & Press Enter. I will help you to create a partition on your drive.

Now the imp. command to format bootable USB to make it normal.

7. Now type “format fs=fat32 quick” & Press Enter. You can also use the “format fs=ntfs quick” command but fat32 is standard for USBs.

8. And Done! You have successfully converted your bootable USB to a normal pen drive. Now type “exit” command & close cmd.

Now the next method…

Method 3: Restore USB drive to Original State Using Third-Party Tools

If you don’t like command-line methods like the above one, then you can also use other third parties tools like:

1. EaseUS Partition Manager
2. Minitool Partition Wizard
3. AOMEI Partition Assistant

And EaseUS Partition Manager works great to convert bootable USB to normal pendrive. Just you have to follow some steps…

1. Insert the USB drive, Open partition wizard.

2. Now Select the USB, Right Click on it and select Format.

3. Now Select the File system and Done!

Now the next part…

When OS X shipped on a DVD a good number of years ago, you always had the convenience of a bootable installer—an OS X installer that could be used to boot your Mac if its own drive was having problems. But to install or reinstall a recent version of OS X, you must either download a non-bootable installer from the Mac App Store or (via OS X’s invisible, bootable recovery partition) download 6GB of installer data from Apple’s servers during the installation process. In other words, you no longer have the same safety net or convenience.

Because of this, I recommend creating your own bootable El Capitan (OS X 10.11) installer drive on an external hard drive or USB thumb drive. If you need to install El Capitan on multiple Macs, using a bootable installer drive is faster and more convenient than downloading or copying the entire installer to each computer. If you want to erase the drive on a Mac before installing El Capitan, or start over at any time, you can use a dedicated installer drive to boot that Mac, erase its drive, and then install the OS (and subsequently restore whatever data you need from your backups). And if your Mac is experiencing problems, a bootable installer drive makes a handy emergency disk.

(OS X Recovery lets you repair your drive and reinstall OS X, but to perform the latter task, you must wait—each time you use it—for the entire 6GB of installer data to download. At best, that’s a hassle; at worst, it’s hours of waiting before you can get started.)

Parallels desktop 13 activation key free. As with previous versions of OS X, it’s not difficult to create a bootable installer drive, but it’s not obvious, either. I show you how, below.

Keep the installer safe

Like all recent versions of OS X, El Capitan is distributed through the Mac App Store: You download an installer app (called Install OS X El to your Applications folder. In this respect, the OS X installer is just like any other app you buy from the Mac App Store. However, unlike any other app, if you run the OS X installer from that default location, the app deletes itself after it’s done installing OS X.

If you plan to use the OS X installer on other Macs, or—in this case—to create a bootable installer drive, be sure to copy the installer to another drive, or at least move it out of the Applications folder, before you use it to install the OS on your Mac. If you don’t, you’ll have to redownload the installer from the Mac App Store before you can use the instructions below.

What you need

To create a bootable El Capitan installer drive, you need the El Capitan installer from the Mac App Store and a Mac-formatted drive that’s big enough to hold the installer and all its data. This can be a hard drive, a solid-state drive (SSD), a thumb drive, or a USB stick—an 8GB thumb drive is perfect. Your drive must be formatted as a Mac OS Extended (Journaled) volume with a GUID Partition Table. (Follow this tutorial to properly format the drive if you’re using OS X Yosemite or older. If you’re using OS X El Capitan, use these instructions.)

Your OS X user account must also have administrator privileges.

Apple’s gift: createinstallmedia

In my articles on creating a bootable installer drive for older versions of OS X, I provided three, or even four, different ways to perform the procedure, depending on which version of OS X you were running, your comfort level with Terminal, and other factors. That approach made sense in the past, but a number of the reasons for it no longer apply, so this year I’m limiting the instructions to a single method: using OS X’s own createinstallmedia tool.

Starting with Mavericks, the OS X installer hosts a hidden Unix program called createinstallmedia specifically for creating a bootable installer drive. Using it requires the use of Terminal, but createinstallmedia works well, it’s official, and performing the procedure requires little more than copying and pasting.

The only real drawback to createinstallmedia is that it doesn’t work under OS X 10.6 Snow Leopard—it requires OS X 10.7 Lion or later. Though it’s true that some Macs still running Snow Leopard can upgrade to El Capitan, I think it’s safe to assume that most people installing OS X 10.11 will have access to a Mac running 10.7 or later.

(If you absolutely refuse to go near Terminal, an El Capitan-compatible version of DiskMaker X is now available, although I haven’t yet had the chance to test it.)

Making the installer drive

  1. Connect to your Mac a properly formatted 8GB (or larger) drive, and rename the drive Untitled. (The Terminal commands I provide here assume that the drive is named Untitled. If the drive isn’t named Untitled, the procedure won’t work.)
  2. Make sure the El Capitan installer (or at least a copy of it), called Install OS X El, is in its default location in your main Applications folder (/Applications).
  3. Select the text of the following Terminal command and copy it. Note that the window that displays the command scrolls to the right.
  4. Launch Terminal (in /Applications/Utilities).
  5. Warning: This step will erase the destination drive or partition, so make sure that it doesn’t contain any valuable data. Paste the copied command into Terminal and press Return.
  6. Type your admin-level account password when prompted, and then press Return.
  7. You may see the message “To continue we need to erase the disk at /Volumes/Untitled. If you wish to continue type (Y) then press return:” If so, type the letter Y and then press Return. If you don’t see this message, you’re already set.

The Terminal window displays createinstallmedia’s progress as a textual representation of a progress bar: Erasing Disk: 0%… 10 percent…20 percent… and so on. You also see a list of the program’s tasks as they occur: Copying installer files to disk…Copy complete.Making disk bootable…Copying boot files…Copy complete. The procedure can take as little as a couple minutes, or as long as 20 to 30 minutes, depending on how fast your Mac can copy data to the destination drive. Once you see Copy Complete. Done., as shown in the screenshot above, the process has finished.

Createinstallmedia will have renamed your drive from Untitled to Install OS X El Capitan. You can rename the drive (in the Finder) if you like—renaming it won’t prevent it from working properly.

Booting from the installer drive

Make Bootable Usb Macos From Windows

You can boot any El Capitan-compatible Mac from your new installer drive. First, connect the drive to your Mac. Then, restart your Mac (or, if it’s currently shut down, start it up) while holding down the Option key. When OS X’s Startup Manager appears, select the installer drive and then click the arrow below it to proceed with startup. (Alternatively, if your Mac is already booted into OS X, you may be able to choose the installer drive in the Startup Disk pane of System Preferences, and then click restart. However, sometimes OS X installer drives don’t appear in the Startup Disk window.)

Once booted from your installer drive, you can perform any of the tasks available from the OS X installer’s special recovery and restore features. In fact, you’ll see the same OS X Utilities screen you get when you boot into OS X Recovery—but unlike with recovery mode, your bootable installer includes the entire installer.
