How To Put Multiple ISO Files In One Bootable USB Disk | Create Multiboot USB Disk

Creating a bootable USB disc comes in handy when we have to re-install our operating system in case of system failure. Keeping the ISO file on portable flash drives is not easy using different tools like Ubuntu Windows USB / DVD Tool and Startup Disk Creator.

There are many operating systems available in the market, either free or paid. Each has many versions and features. You can not waste a flash drive for each of them. It would be great if you put all ISO files on the flash drive and use a multiboot USB. Life is very easy when there are several ISO files in a single storage media.

The process of making the multiboot USB disk is quite simple. For Windows OS, these multiboot USB drives can be built using a popular tool known as WinSetupFromUSB. This allows you to put several ISOs in an installation disc.

You can put Windows and Linux in the same bootable disk or you can make a master installation disc of Windows 7, Windows 8.1 and Windows 10. The choice is up to you. In addition, making multiboot USB can be very helpful for Linux users, who have to deal with different distributions, each of which has a set of features.

You should arrange a sizeable USB flash drive. To do three Windows ISO accessories in the multiboot USB disk, you will need a 16 GB flash drive.

In case, you are searching for some bootable USB tools, here are some suggestions.

How to create a multiboot USB disk in Windows?

• Download WinSetupFromUSB. Remove this file.

• Connect the flash drive to your computer.

Note: WinSetupFromUSB does not support dual-ISO, that is, it can not be 32-bit and 64-bit versions in a single ISO. This will show an error message.

• Click on GO. A data deletion alert message will be displayed. The reason for this is that you have chosen to format flash drives. Click Yes.

Note: Be sure to check the name of the Flash Drive before clicking Yes. In addition, you will format some other connected storage media.

• Another warning message will be displayed showing you that all partitions will be erased. Click Yes.

• Next, it will ask for the folder name. Type in the desired one in 30 seconds or it will auto select. Click OK.

• This boot menu will ask for the name. This will appear when you run a multiboot USB on some PCs and choose an operating system. Type your desired name like Windows 8.1 64-bit. Click OK.
