10 easy steps to install Win10 from a DVD or USB

If you’re going to upgrade from Windows 7 SP1 or 8.1 Update to Windows 10, and
you want to keep your data and programs untouched, we strongly recommend you to perform
the online upgrade. As long as you stick to
upgrading 32-bit Windows 7 to Windows 10 32-bit or 64-bit to Windows 7 64-bit Win 10, the online
installer works great.
If you buy a shrink-wrapped copy of Windows 10, you get a DVD (or
USB drive) that’s ready to boot. If you download an ISO file, follow the instructions
in the sidebar * making an ISO file usable * to turn the file into a bootable DVD or
USB drive.
1. With your old version of Windows running, insert the Windows installation
disk in the DVD drive, or the installation USB in a USB port.
2. In Windows 7, choose Start, Shut Down to go through a full shutdown. in Windows
8.1, click the power icon next to your name on the Start screen and
choose Shut Down.
Windows may offer to install itself while you’re trying to shut down. If it does,
click the Cancel button.
3. Power off the PC, wait a minute, and then turn on the power.
If the PC can start (or boot) from the DVD drive or USB drive, you see something
like this on the screen: Press any key to boot from CD or Press Esc to choose

4. Press any key is recommended.
If the PC does not offer to boot from the DVD drive or USB stick, you have to
look in your PC’s documentation for the correct setting in your PC’s BIOS. If
you’re not familiar with your PC’s BIOS, go to the website for your PC manufacturer
and search for the term change boot sequence. The process may be
complex, particularly if you have something called a UEFI secure boot enabled.
Only your computer manufacturer can tell you how to deal with UEFI.

latest updates. If you do, choose * Go Online to Install Updates and New *
click Next.

and then click Install Now.
