The traditional method of installing a Microsoft operating system on a computer is via an optical drive (DVD or CD). But, the Eee PC does not come with an inbuilt optical drive (Eee PC 1000H). So, how does one install Windows 7 on it? By using a USB flash drive with at least 4GB capacity as the installation media. Well, firstly let me describe the traditional method of installing Windows 7 using an USB flash drive as found on many websites on the internet.Method 1
Requirements : USB flash drive (minimum 4GB) and Windows 7 installation files in DVD or copied to computer directly or as an ISO image.
Follow the steps given below to create bootable Windows 7 USB drive using which you can install Windows 7 easily -
1. Plug-in your USB flash drive to USB port and move all the contents from USB drive to a safe location on your system.
2. Open Command Prompt with admin rights -
Type cmd in Start menu search box and hit Ctrl+Shift+Enter
Or
Go to Start menu > All programs > Accessories, right click on Command Prompt and select Run as administrator.
3. Type in the following commands in the command prompt and hit Enter after each command -
DISKPART
LIST DISK
Now note down the Disk number (ex: Disk 1) of your USB flash drive. Let us say flash drive disk is Disk 1.
4. Assuming that your disk drive is “Disk 1” type all the below commands one by one. If you have Disk 2 as your USB flash drive then use "Disk 2" in place of "Disk 1".
So, type the commands given below and press Enter after each command -
SELECT DISK 1
CLEAN
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
FORMAT FS=NTFS
ASSIGN
EXIT
Don’t close the command prompt as we need to execute one more command at the next step. Just minimize it.
5. Next insert your Windows 7 DVD into the optical drive and check the drive letter of the DVD drive. In this guide ,let me assume that your DVD drive letter is “D” and USB drive letter is “H” (verify by opening "computer" from start menu). In case of ISO image, extract all the files to a folder using WinRAR.
6. Maximize the minimized Command Prompt from the 4th step.Type the following command now and hit Enter after each command -
CD /d D:
“D” is your DVD drive letter.
If the files are extracted to a folder in your computer, say "C:\Win7", then type -
CD /d C:\Win7
Now type -
CD BOOT
7. Type the command given below to update the USB drive with BOOTMGR compatible code.
BOOTSECT.EXE/NT60 H: “H” is your USB drive letter.
8. Copy your Windows 7 DVD contents to the USB flash drive.
9. Your USB drive is ready to boot and install Windows 7. Only thing you need to change the boot priority at the BIOS to USB from the HDD or CD ROM drive. This can be done by pressing F2 repeatedly while booting up the computer.
That is it.
Method 2
Now, second method. If the USB flash drive used is a plain vanilla one with only a single partition on it, instead follow the simple steps given below -
1. Plug-in your USB flash drive to USB port and move all the contents from USB drive to a safe location on your system.
2. Format your USB flash drive by using Windows Format Tool. In "Computer", right click on your USB flash drive and select "Format". Quick Format using NTFS file system.
3. Copy all the Windows 7 installation files to your USB flash drive from DVD or your computer.
4. Your USB drive is ready to boot and install Windows 7. Only thing you need to change the boot priority at the BIOS to USB from the HDD or CD ROM drive. This can be done by pressing F2 repeatedly while booting up the computer.
That is it. Easier? You bet! If this method does not work for you, you can always use the first method.
