Install the operating system without an optical drive can be internal or external (connected to USB) hard disk.
When you install from the internal drive is done most easily if you have two or more hard drives.If one hard drive, it must be divided into several sections.In the absence of several major sections should remove the hard drive from the computer and connect it to a computer with a working operating system.Then make the necessary layout - select one primary partition, format it (the preferred file systematically FAT32, as formatting is acceptable in NTFS, but it complicates the process of installation), copy the distribution files of the operating syste
If multiple hard drives, you simply copy the operating system distribution in the root folder of any hard disk drives (in addition, which then will be installed).
Then, to start the installation process, you will need bootable media DOS, which can be created in the operating systems Windows when you format a floppy disk or flash drives.To simplify the installation process can also be copied to the support of any of the DOS-navigators (Norton Commander, DOS Navigator, Volkov Commander).
Boot from the bootable media.After starting the DOS prompt, go to the I386 folder of the Windows distribution and type winnt.exe or winnt32.exe depending on the type of operating system.
This starts the process of installing the operating system.After passing the first stage of the installation, switch the load on your hard drive with the installed system.
Running from external media is no different than installing from the internal drive, but you can install Windows from your hard drive, without additional boot devices, and make a bootable hard drive itself and booting fromit.
by connecting an external hard drive to your computer and use to prepare the hard drive of one of the plurality of designated programs - PE-to-USB, WinSetupFromUSB or the like.After this installation with an external hard drive will not differ from the installation from a standard CD.
