It does not matter whether you use macOS or Windows 10. It’s just a matter of time until your device will refuse to start, which could happen for many reasons, including (and not limited to) file corruption, hardware failure, and buggy update. If the unexpected happens with an Apple computer, you can use a macOS bootable USB with the installation media to repair it.
This is one of the main reasons you should consider making a macOS bootable USB when your device is working properly. However, if none of your devices (MacBook, MacBook Air, MacBook Pro, iMac, Mac Pro, or Mac Mini) aren’t working when you need them the most, then you can use a PC to rescue your Apple device. You can use a Windows 10, Windows 8.1, or Windows 7 device to quickly create a USB bootable installation media to reinstall macOS Catalina or Big Sur on your Mac.
In this guide, you’ll learn the steps to create a macOS Catalina bootable USB installation on Windows 10, which you can use to reinstall or upgrade the Apple OS.

Then click on ok. Choose mac osx el capitan dmg file. Since the file is huge so it will take quite time to complete. It may take about 20 to 30 mins or more.
- Step 2: Next, we’re going to need to format the USB flash drive to get it into a state where it can accept the payload for the installation of El Capitan. Plug the USB flash drive into an available USB port and launch the ‘ Disk Utility ‘ application. Make sure that the USB flash drive is selected within the left sidebar, and then select.

To create a bootable USB drive with macOS, use these steps:
Download and install TransMac on the Windows 10 device.
Quick note: This is a paid software, but it gives you a 15-day trial, which is more than enough time. (If this works for you and you want to support the developer, you can purchase the full version.)Connect the USB flash drive. (If you have any data on the flash drive, remember to make a backup, as everything on it will be erased.)
Right-click the TransMac app and select the Run as administrator option.
Click the Run button. (If you’re using the trial version, wait 15 seconds.)
Right-click the USB flash drive, select the Format Disk for Mac option from the left navigation pane.
Quick note: You want to do this before creating the bootable media because there is a good chance that the drive was formatted using a Windows device. If this is the case, the chances are that it’s using an MBR partition, and the USB drive needs a GPT partition to work on a Mac.Click the Yes button to format the drive on the warning message.
Confirm a name for the drive. For example, “macOS bootable USB.”
Click the OK button.
Click the Yes button.
Click the OK button.
Right-click the USB flash drive and select the Restore with Disk Image option from the left navigation pane.
Click the Yes button to confirm the erase of the USB flash drive data.
Click the browse button on the right.
Select the .dmg file with the macOS installation files.
Click the Open button.
Click the OK button.
Click the Yes button.
Once you complete the steps, you can now insert the USB flash drive on your Mac computer to install, reinstall, or upgrade the operating system to the latest macOS version, which can be Sierra, Catalina, Big Sur, or higher.

How to use El Capitan Installer for a Clean Install?
01. El Capitan Clean Install on Empty Volume with El Capitan Installer
This is the easiest method for the clean install. Here, you can install the OS X El Capitan Installer onto an empty volume, or you can use a storage space that has the content which no longer needed and don’t mind removing. What it matters here is that you don’t use the current startup volume as the destination here. What makes this method easier is the fact that it is possible to perform this clean install while booted from the current startup drive. You don’t need a special, custom-made startup environment for the empty volume clean install. All you have to do is, start up the installer and go.

USB installer and El Capitan Installer in Apple Store
El Capitan Installer is only available in the Mac App Store. So you can only download it from the App Store. By the way, having a USB installer to perform the El Capitan is a good idea. Because having a copy of the OS version in a separate device ensures that you always have a backup plan to install it or re-install it on the PC. When you have the USB installer with the El Capitan Installer in it, you no longer need the internet connection or the access to the Mac App Store to perform the upgrade.
