How to install WIN 7 without a DVD-ROM/CD-ROM drive?

[MaGl]

Hello.

Situation: Right now i got Windows 8 on my Laptop. It was pre-installed and i don't have a Windows 8 CD. I don't want to use Windows 8 anymore and want to install Windows 7 instead. I have a Windows 7 CD and a Windows 7 Key.

Problem: My Laptop has NO DVD-ROM/CD-ROM drive.

Question: Is there any other way to get Windows 7 installed, that doesn't require a DVD-ROM/CD-ROM drive?

Your help is much appreciated, thank you.

Read over the steps to Downgrade Windows 8 to Windows 7.

In addition to the changes in BIOS setup to disable Secure Boot and take note of settings of CSM, Legacy BIOS and UEFI Boot for possible change later, you must use a special tool to format a 4+gb Flash stick correctly, using only Option One of UEFI Bootable USB Flash Drive - Create in Windows making sure that the settings pictured there do not jump around after you add the ISO file.

The stick once formatted must be booted as a UEFI device, all partitions deleted then create and format New as desired or just click Next to have installer do it for you.
