how to install Windows XP, 7, and the vista from flash

Over time, computer or laptop is usually going to be heavy and slow. The causes can vary, such as: too many applications installed, the registry is not optimal because it is often install and uninstall, or even some system files corrupted due to virus or trojan.

In some cases, these problems can be solved one by one partial. But not infrequently, too, the problem is so complex that the best way to solve it is to reinstall the OS. However, it is an inevitability that one day the laptop or computer needs to re-install the operating system.

A common method to reinstall the Windows OS is to use a bootable CD / DVD of Windows that already exist. But this turns out to be a problem in itself, especially for laptop computer or a CD / DVD ROM is damaged. This is normal given the CD / DVD ROM device that is relatively more easily damaged. In addition, several types of circulating netbooks now deliberately not equipped with a DVD ROM drive to push the sale price. Then how could they do re-install? Do you have to buy an external DVD?

Fortunately since a few years ago, computer motherboard / laptop / netbook is equipped with features that allow it to boot from USB. With this feature it becomes possible to boot from a USB Flash Drive (UFD). Of course UFD we need to prepare in such a way that can be used for this purpose. In this article will discuss about how to create a bootable UFD for Windows 7 and Windows XP .

WINDOWS 7

What is needed:

1. Source Installer Windows 7. If your source form of a DVD then you need a DVD ROM (for those who do not have to borrow an external DVD ROM or borrow a laptop / computer DVD ROM friend who was still good, hehe ..). If your source form of the ISO then you do not need a DVD ROM drive again of course.
2. UFD minimum of 4G. If Source Installer Windows 7 you already include Service Pack 1 , the possibility of 4G is not enough so you need a larger UFD. In this example I use a UFD 8G.
3. This method can only be done under Windows Vista or Windows 7. So if the OS you're using is Windows XP then you can not do it this way.

The steps are:

• Prepare and plug the UFD. Make sure the data is already backed up because during the later processes will be formatted UFD.

• Go to Start -> All Programs -> Accessories , then right-click onCommand Prompt and select Run As Administrator .

• If it appears my windows UAC click Yes .

• Type in DISKPART and press Enter .

• Type LIST DISK and press Enter .

• Take a good directory or drive letter where the Windows 7 Source Installer. In this example I have is on drive E.

• Go back to the Command Prompt window again. Now we want to go to the directory where Source Installer Windows 7 (in this example is on drive E). Thus type E: and press Enter .

• Type CD BOOT and press Enter .

• Look carefully at your UFD drive letter. In this example I have in the drive UFD I. So type bootsect / NT60 I: and press Enter (UFD is like you are in K, then the command to type is bootsect / NT60 C: ).

• Command Prompt window can now be closed. Next live copy all the files in the Source Installer Windows 7 to your UFD.

• When you want to use do not forget to set the BIOS so I can boot from USB.

• UFD result you can use to install or repair Windows 7

2. UFD at least 2G.
