membuat Dual Boot Installation dengan Windows 8 dan Windows 7 atau Vista

   Information

This will show you how to set up a dual boot installation with Windows 8 Developer Preview andWindows 7 or Vista when Windows 7 or Vista is installed first.

   Note

Windows 8 Developer Preview System Requirements 

Windows Developer Preview works great on the same hardware that powers Windows Vista and Windows 7:

• 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
• 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
• 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
• DirectX 9 graphics device with WDDM 1.0 or higher driver
• Taking advantage of touch input requires a screen that supports multi-touch

EXAMPLE: "Choose an operating system" Screen at BootNOTE: This is the new "Windows Boot Manager" screen that Windows 8 uses now to allow you to select either Windows 8 (Windows Developer Preview) or say Windows 7 to start when your boot or restart the computer. Clicking on the Change default or choos other options link at the bottom will allow you to change the default time to wait before starting the default OS, change the default OS to start automatically after wait time, or to choose a recovery option.








Here's How:

1. Start Windows 7 or Vista, and log on to an administrator account. Go to either step 2 or 3 below for what you wanted to install Windows 8 on.

2. If you Already Have a Empty Hard Drive or Partition to Install Windows 8 On

A) Go to step 4.

3. If you Want to Shrink a Partition to Install Windows 8 On

A) Shrink a partition, such as the Windows 7 partition (ex: C: drive), in Disk Management by at least 20GB (20480MB) (1GB=1024MB) to have unallocated space to be able to install Windows 8 on. (see screenshots below)

NOTE: This example has the 100 MB System Reservered partition that Windows 7 creates when installed on a unallocated HDD. If your Windows 7 installation does not have the 100 MB System Reservered partition, then that is fine since this will still work to dual boot with Windows 8. Just do not delete the 100 MB System Reservered partition if you do have one.

4. Do either step 5 or 6 below for how you want to start installing Windows 8.



5. To Install Windows 8 at Boot to Dual boot with Windows 7 or Vista

A) Insert or connect your Windows 8 installation DVD or USB thumb drive, and restart the computer to boot from your Windows 8 installation media.

B) Go to step 7.

6. To Install Windows 8 from within Windows 7 or Vista to Dual Boot with

A) Do step B or C below depending on if you are using a Windows 8 DVD/USB or a Windows 8 ISO.


B) Insert or connect your Windows 8 installation DVD or USB thumb drive. In the Computerwindow, right click on the Windows 8 installation USB/DVD drive, and click on Open. Go to step6D.


OR

C) After installing a free program like 7-Zip, right click on the Windows 8 ISO file, select 7-Zipand click on Extract Files, extract the ISO file to a folder (ex: WindowsDeveloperPreview) on your Desktop in Windows 7 or Vista, and open the extracted folder when finished. Go to step6D.

NOW

D) Open the sources folder first, and run the setup.exe file inside the sources folder. (see screenshots below)

   Warning

If you run the setup file in the root directory instead of the one in the sources folder, then you will be upgrading Windows 7 or Vista to Windows 8 instead of dual booting with Windows 8 and will lose Windows 7 or Vista.

E) Click on the Go online to get the latest updates for installation option. (see screenshot below)

F) Continue on to step 7.

7. You can now finish doing a clean install of Windows 8 to either the empty HDD or partition from step 2, or the unallocated space created in step 3. Be sure to not select your Windows 7 or Vista partition to install Windows 8 to. If you do, Windows 8 will replace it. 

NOTE: The screenshot below is at step 6 in the clean install tutorial.

8. When finished, you will be in Windows 8 with Windows 8 set as the default OS to start after the wait time. Restarting Windows 8 will allow you to be able to select what OS you would like to start like in the example at the top of the tutorial.

Membuat Dual Boot Windows 7 dan Ubuntu

This tutorial is a simple guide that will explain the two easiest ways to setup and install Ubuntu to dual-boot with your current installation of Windows. One option describes how to do this via WUBI. Another describes how to do this as a native dual-boot.

   Warning

Neither Designer Media Ltd (Sevenforums) nor myself are responsible for any problems that occur from the following tutorial.

   Note

Please bear in mind that the WUBI installation method installs Ubuntu as if it is an application on Windows. It does NOT use its own partitions.

OPTION ONE

---

Using Wubi Installer

Step 1: Go to this website, download and run the Wubi installer.


Step 2: Select the hard drive you wish to install it on. Keep in mind it will NOT erase Windows.

Step 3: Select the amount of space you want to give tos Ubuntu to use. I recommend 3GB.


Step 4: Select your desktop enviornment. This is personal prefernce, if you are new to Linux I suggest sticking with Ubuntu.


Step 5: Select your language.


Step 6: Set your screenname. Note that this cannot contain capitalized letters of any kind.


Step 7: Set your password. When you have completed that hit the install button and wait!


Step 8: When it finishes downloading and installing Ubuntu, just restart to boot into Ubuntu!

OPTION TWO

---

Native Install

Step 1: Burn a CD/DVD with the Ubuntu ISO through Windows.


Step 2: Boot from the CD/DVD when you start up your computer.


Step 3: 
Press the up button the moment something appears on that screen and select a language.

Step 4: Select the option 'Try ubuntu without installing'.

Step 5: When the desktop appears double click the icon on the desktop called 'Install Ubuntu'.

Step 6: When the installer launches fully, select your language and hit the foward button.

Step 7: On this screen you'll want to choose that options you want. I suggest selecting them both. Hit the foward button again after you select what you want.

Step 8: On this screen you'll want to select the 'specify partitions' option and click foward.

Step 9: Here as you can see we already have some unallocated space, click it and select the 'Add' button. (Note: You can select an already created partition, make sure not to overwrite your Windows partition!)

Step 10: A window should pop up, you should make the mount point '/' and the 'Use as' EXT4 filesystem. Click Ok when done.

Step 11: After that click the 'Install Now' button and follow the onscreen instructions. 


Step 12: You'll be prompted to reboot after its finished, reboot and select the top option in the Grub 2 Boot Loader and you're now in Ubuntu!

Membuat Dual Boot Installation dengan Windows 7 and XP

   Information

This will show you how to install Windows 7 and XP to dual boot with when you already have either Windows 7 or XP installed first.

   Note

With a dual boot installaton, you will have two operating systems (OS) installed. When you start the computer, you will have the choice to choose which OS you would like to start up to. This method is the easiest way of doing a dual boot with these two operating systems.

   Tip

When dual booting with another OS (ex: Vista or XP), you may not always have that OS partition show up in Computer with a driver letter in Windows 7. If this happens, then you will just need to add a drive letterto the OS (ex: Vista or XP) partition in Windows 7 Disk Management for it to show up in Computer with adriver letter.

   Warning

To stop XP from deleting your Windows 7 System Restore Points everytime XP is started, then see System Restore Points - Stop XP Dual Boot Delete to hide Windows 7 from XP.
