Software recommendation: without making a system disk can also install a new system

Usually, you need a Windows installation CD or USB installation disk to install Windows. In fact, in the absence of an installation disk, you can use WinNTSetup to install Windows directly on a hard disk, as long as you have a computer that can boot into Windows at hand. Even if you don’t have a computer with Windows, you can use it to complete the Windows installation task with the help of any bootable WinPE media.

1. Borrow the current system to install Windows

To install Windows to a new hard drive, first mount the drive to an available computer, restart the computer into Windows. run WinNTSetup and select the Windows category you want to install (for example, if we want to install Windows 10, select the second tab). Assuming that the disk letter of the newly mounted hard drive is E, specify in the WinNTSetup window the location of both the boot drive and the installation disk as drive E (Figure 1).


Next, select the location of the Windows installation files. The folder of the installation files is the sources folder where the install.wim file in the Windows installation ISO image package is located. First, through File Explorer, right-click on the previously downloaded ISO file and select “Open as” to “Windows Explorer”. This will bring up an open virtual CD-ROM drive in Explorer with a disk drive assigned to it (in this case, the G drive) (Figure 2). The installation file location in Figure 1 should be selected as “G:sourcesinstall.wim”.


If the ISO used is a composite version of the installation image, you will also need to select the version you want to install from the “Version” option list (here, select “Windows 10 Professional”). Finally, click on the “Start Installation” button to begin the installation process of the Windows system files. After the installation process is finished, install the hard drive to the target computer and set it as the first self-boot device, then boot the computer. Then go to the Windows installation configuration and follow the configuration wizard to complete the Windows 10 installation process. 2.

2. Find a WinPE to install the new system

If you don’t have a Windows bootable computer around, you can also find a random WinPE media that can boot, such as a WinPE USB drive or CD. First extract and copy WinNTSetup tool and Windows ISO to a WinPE flash drive. If you use a WinPE CD or WinPE boot disk with insufficient space, you can copy WinNTSetup and Windows installation files to another flash drive with enough space for calling. After that, boot your computer with WinPE, run WinNTSetup from the flash drive, and then install Windows to the new hard drive as in step 1 above.

Tip: Optimize the system settings during installation

The “Optimize” button in the WinNTSetup installer also allows you to customize the items that you want to optimize when installing Windows (Figure 3). These include the style of use in Explorer and the disabling of some system items.
