In this situation, you will need to shrink the volume or partition (for information on how to shrink a volume or partition in Windows, see the previous article: How to Shrink a Volume or Partition).

You may be asked to do this Press any key to boot from DVD, if you press any key on the keyboard to continue.

Select your language, click on Install now button and choose the customized option when prompted for the type of installation you want to perform. 4. In the next step, find the new partition you just created in the drive list. Click on next sit back and relax while the installer takes care of the rest. Caution: Be careful and make sure you select the correct partition, because you are about to say goodbye to the contents of that partition. 5. When the installation is complete, your computer should boot into the new Windows 8. It is likely that your computer will reboot several times and you will be greeted with the completely redesigned Windows 8 Welcome Screen. You are now ready to log in. So far, you’ve shrunk, created a new partition, and successfully booted Windows 8 and Windows 7. The next step is optional, but it would be advisable to do so.

Step 3: how to make Windows 7 the default boot OS

On first boot, you’ll see that Windows 8 displays a new Start Menu UI, allowing you to choose the version of Windows you want to boot. Windows 8 will be the default, the one selected to boot first if you don’t manually choose Windows 7 after 30 seconds. As much as you love Windows 8, there’s a good chance you don’t want it to be your primary operating system yet, so the next steps are to make Windows 7 the default operating system in the boot menu: 1. On the start menu, click Change the default settings or choose other options button. 2. Click Choose the default operating system. 3. Finally, choose the default operating system. There you can choose Windows 7 and from this point on your system will boot into Windows 7 by default and when you feel like continuing to try Windows 8, restart your computer and select it from the start menu.

Installing Windows 8.1 this way gives you a clear, clean choice screen at system startup of which operating system version you want to use. So how do you accomplish this? It’s really not much more difficult than your typical Windows installation, with a couple of preparatory steps before you start the actual setup. Follow the procedure below and you’ll be able to switch back and forth between operating systems at will. One preliminary note, though: This multi-boot setup only works with Windows 7 and Vista: To set up a multi-boot system with Windows XP or Ubuntu, you’ll need a third-party multi-boot tool such as the excellent EasyBCD(Opens in a new window) from NeoSmart Technologies. choose os Step 1: Back Up! Before you attempt this, however, you should back up your existing Windows PC. You never know what will happen when installing a new OS.

Download the Installer

STEP 3: Download the Installer Now it’s time to actually get your copy of Windows 8.1, in the form of a downloaded .ISO disk image file. There are several ways to go about this, which I’ve explained in How to Download Windows 8.1. You can download Windows 8.1 Preview from Microsoft’s Download Windows 8.1 Preview(Opens in a new window) page. You have a choice between 32-bit and 64-bit; since most modern PCs are 64-bit capable, that’s a better choice. Use Windows 7’s disc image burning capability to create an installer DVD from the ISO file (by clicking Burn disc image from its right-click context menu), or you can create a bootable USB key using the Windows 7 USB/DVD Download tool(Opens in a new window). You must boot to the upgrade disk or USB drive: You can’t create a dual-boot system by starting the installer within Windows while it’s running. download Step 4: Run the Windows 8.1 Installer Pop in the installer DVD you burned or the USB stick you prepared, and restart your PC.

Accept the software license, and after this, choose Custom, not Upgrade. Now is when you’re presented with the choice of partitions, click «Drive options (advanced)» and then select the Unallocated space we created in step 2. Next, click New from the drive options icons below. Accept the full size displayed, and hit Apply. choose partition Now we’ve got a freshly formatted partition to install Windows 8 on. Hit Next, and setup is off and running. Go have a coffee or other snack of your choice; it takes about 20 minutes.

Step 5: Restart Your New System Your system will reboot into Windows 8.1, where you’ll go through the typical first-run options of choosing a color pattern, WiFi connection, and Microsoft account. But the next time you reboot the PC, you’ll see the option screen shown at the beginning of this article. choose os By default, this screen displays for 30 seconds, and then Windows 8.1 launches.

You can also use troubleshooting tools like Refreshing or Resetting your PC, and you also have access to advanced options like system recovery and a command prompt.

Detailed steps to shut down it are as follows: Go to Control Panel, select View by: Small Icons, choose Power Options, select Choose what the power button does, uncheck Turn on fast startup, and click Save changes. disable fast startup After these steps, we can shut down the computer to install Windows 7 if we have had Windows 7 installation disk, like CD, DVD and USB flash drive.

If you do not know which key to press, try searching how to enter BIOS plus your BIOS type or computer trademark on the internet. I press F2 to enter the BIOS setting: enter BIOS Under the Boot menu, we can see clearly that my computer is configured with UEFI boot, but Legacy Boot Option ROM is disabled. Under this situation, we can only install 64 bit Windows 7 on a GPT disk. Why? According to Microsoft, we know booting from GPT disk must be under UEFI mode, but UEFI firmware does not support 32-bit system. Therefore, 32 bit Windows 7 cannot be installed to a GPT disk. Of course, when Legacy BIOS is supported, 32 bit Windows 7 can be installed to an MBR disk. Some mainboards can either support UEFI BIOS and Legacy BIOS: under boot menu Then make corresponding changes in BIOS: 1. Disable OS Optimized Defaults if there is such an option. Enabling it will restore all settings to the state when Windows 8 is installed. Under this state, only Windows 8 can be installed. disable os optimized defaults 2. Disable Secure Boot. It is a feature specially designed to defense virus or malware. Motherboards configured with secure boot are built with some public keys. Only programs or systems that have been signed by these public keys can be loaded. Most of the time, Windows 7 hasn’t been signed. As a result, it cannot be loaded if secure boot is enabled. disable secure boot 3. If you are going to install Windows 7 (both 32 bit and 64 bit) to an MBR disk, please enable Legacy BIOSin boot mode, which has been introduced. 4. Set boot priority order. If you want to install Windows from CD or DVD, make CD-ROM as the first boot device. If installing from a USB flash drive, make the removable device as the first boot device.

Microsoft has given such a warning on its official website: You must install the older operating system first, and then install the more recent operating system. If you don’t (for example, if you install Windows Vista on a computer already running Windows 7), you can render your system inoperable. This can happen because earlier versions of Windows don’t recognize the startup files used in more recent versions of Windows and can overwrite them.
