Install Windows 7 from USB Disk

Today, I tried to install Windows 7 Ultimate on HP Mini 210 edition. It so difficult since HP Mini has no optical drive included. How could I install this OS? Ah, finally I found an alternative way to install it and I want to share it in this article.

All you have to prepare for this project is a Windows 7 DVD Installer, a flashdisk at least 4gb, and another computer running with Windows 7 OS that has optical drive included or external DVD-ROM.

Firstly, lets begin to create usb installer. Connect flashdisk on your computer and format it to NTFS.

Open command prompt with admin right. Type CMD in Start Menu search or go to Start Menu >> All Programs >> Accessories >> Command Prompt.

Type the following command in the command prompt:

  • First, type DISKPART and hit enter to see if DiskPart already installed on your system and playing with this handy tool.
  • Next, type LIST DISK command and note down the Disk Number of your FlashDisk. I assume that FlashDisk locate at Disk 1.
  • Lets begin create a primary partition for your FlashDisk, follow the command below and execute one by one.

SELECT DISK 1

CLEAN

CREATE PARTITION PRIMARY

SELECT PARTITION 1

ACTIVE

FORMAT FS=NTFS

(format process may take few seconds)

ASSIGN

EXIT

Don’t close the command prompt as we need to execute one more command at the next step.
Next, insert your Windows 7 DVD Installer into the optical drive and check the drive letter of the DVD drive. I will assume that the DVD Drive Letter is “E” and the USB Drive Letter is “H”.
Back to Command Prompt, locate your directory to E: (DVD Drive Letter), and then open directory BOOT.

C:\> E:

E:\> CD BOOT

E:\boot>

Type another command to update the USB drive with BOOTMGR compatible code.

BOOTSECT.EXE /NT60 H:

(where “H” is your USB Drive Letter)

Copy your Windows 7 DVD contents to the USB flash drive.
Your USB drive is ready to boot and install Windows 7.
