The eye-catching Windows 7 starts global beta, if you are planning to try it, but don't want to give up the original XP or Vista system, this article will show you how to implement it in these few Double boot between systems.
Confirm that you have downloaded a full copy of Windows 7 and engraved it on a DVD for a fresh installation. To handle this step, you must use today's popular burning tools, such as: ImgBurn, which is free to use, just to burn Windows 7 ISO files to DVD. Next, we proceed to the second step.
Before installing Windows 7, first, all you have to do is create a new logical partition to install the new system.
As for how to partition, depending on whether you are currently XP or Vista, if Vista is better, because it comes with a partitioning tool, and XP does not, you may need to use third-party tools to partition. Operating System
To create partitions in Windows XP, you need to download some third-party partitioning tools. There are many such tools available. I recommend using GParted Live CD. Recommended reason: It is a free, open source and free tool, itself is an ISO CD, support for self-starting, with the functions required for various partitions.
Download the GParted Live CD from here, burn it to CDR, reboot the system and boot from the CD, and go directly to the partitioning tool.
The use of Gparted Live CD will not be described here. In this article, its role is:
1. Adjust the current system partition size, make room for Windows 7 (according to the official minimum requirements of 16GB).
2. Create a new partition from the freed space.
3. Confirm and save the above settings.
Creating Partitions in Windows Vista
When you find that Microsoft's brothers have integrated partitioning tools into Windows Vista, you will be pleasantly surprised. Yes, it is not difficult to find it:
Go to Control Panel-->System Maintenance-->Administrative Tools--> Computer Management. The partitioning tool is just below the disk management area.
As we said before, the new partition created in Windows Vista can also be no less than 16GB, please remember that this is the minimum system requirement for Windows 7. After confirming that it is correct, select “New Simple Volume".
The main steps have been completed, and the rest of the tasks are much simpler: install Windows 7 in your new partition. Remember to set the CD boot in the BIOS.
The installation wizard for Windows 7 is quite simple. When choosing the installation type, be sure to choose Custom (Advanced) to install Windows 7 in your newly created partition by manual setting. Be careful with this step, because once you select the wrong partition, you will completely erase your previously installed system!
The installation process is in progress and may need to be restarted several times, all of which is done automatically by the installer. Eventually, you will be prompted to create an account, enter your license key, and complete the installation.
