Create multi-bootable Windows 7,8,10 USB without formatting
0. Get WinUSB v3.2 - multiboot
1. Choose USB flash drive
The first you need to choose a flash drive wich will be multi-bootable. You need a USB stick at least 4 GB of free space.
When you plug it in, I will show it automatically in combo-box. The upper horizontal line below of stick name represents the ratio of free and used space. The second line represents a space on drive required for placing selected distributions. If you remove some data from selected drive or unplugging it, I'll see it automatically.
2. Define a distributions list
When USB drive chosen, you may add any number of distibutions to the list by clicking ISO or DVD button depending on what you have.
Windows Installation dvd
Windows ISO file
If you currently do not have any of them, don't worry, it's extremely simple to download Windows ISO from Microsoft website!
Let me show, where you can get it3. Choose file system, if necessary
When you add necessary Windows distributions click "Next" button to open the "Format settings" form.
If you have enough space on flash drive to put windows distribution to it without remove something, as on screenshot bellow, I'll ask you whether you want to format it to one of known operation systems to get clean Windows USB drive.
But if space is not enough, I will have to insist on formatting to release it, because I don't know what files on drive are important for you and what does not. Of course you can click "Back" button, transfer your files in a safe place, then open "Format settings" again.
In text under check-boxes, you can see additional information about selected by default work mode and causes of this choice.
Ok! When you will ready just click "Yes" button, I'll take care of the rest!
4. Burning process
After you submit format settings by clicking "Yes" button, process will start. When format will finished/skipped, all selected distributions will turns to written to a USB drive.
Cancel, deactivate and activate distributions
While burning flash drive, you can do action bellow:
- Cancel current burning
