I recently installed Microsoft Windows 7 on my desktop (its awesome). Although it was one of the seamless installation sessions I have ever had (since MS-Dos 6.22), I had a few hick-ups. I burned Windows 7 ISO on a DVD but some how the image did not get burned properly and corrupted my Windows 7 install (see more on how to remove Windows 7 from dual boot). I decided to use USB stick as it does not require 'burning' of an image and is faster than DVD.
My instructions assume that you
have the following:
- Have Windows XP (32-bit) Professional on your current machine
- ISO image of Windows 7 (32-bit or 64-bit) Any Version
- An image mounting tool. I used Daemon Tools Lite (Free) but you can go with any other one (Alcohol 120%) if you prefer.
- An unzipping tool. I use 7-Zip (Free) but any other one (Winzip, WinRAR, etc.) would work as well.
- A 4GB USB flash drive.
Here is what you
will need to download:
- MBRWizard (Free) for Windows XP
- Bootsect (Free) for Windows XP. Scroll down where it says 'Save file to your PC'. Note: Windows 7 image has a bootsect file however, if you are running 32-bit XP and have a 64-bit ISO image, you will need to download this file as Windows 7 version of bootsect will NOT work and will give an error that 'bootsect is not a valid Win32 application'.
And here are the
steps:
1) Plug your USB drive. Go to "My Computer". Right click the flash drive and click format. Check the box "Quick Format". You can leave all the other settings as is.
2) Click 'Start' then select 'Run'. Type CMD and hit OK to open up a terminal screen.
3) In the terminal screen type "cd\" to go to the C root (C:\).
4) Now type "convert
X: /fs:ntfs". Where
X is letter assigned to your flash drive.
Minimize your terminal window for now
5) Download
MBRWizard and extract the file 'MBRWiz.exe' using unzipping tool, to your desktop.
6) Copy the extracted 'MBRWiz.exe' file and go to "My Computer". Right click the 'C:' drive and click
paste to copy the 'MBRWiz.exe' file to your C:\ drive. (
no need to create a separate folder)
7) Download the
Bootsect file and do the same - copy to your C:\ drive.
Maximize your terminal session
8) Type
"MBRWIZ /list". You will now see the detailed table for each of the disk, including your Hard disk. For example you may see table for
Disk0,
Disk1,
Disk2,
Disk3, etc.
9) From the output of the above step,
note the
disk number of your flash drive. You can tell by the size and the drive letter toward the bottom right of each table.
10) Type
"mbrwiz /disk=
Y /active=1". Where
Y is
disk number that you saw was associated to your flash drive.
11) Now type "bootsect /nt60
X:". Where
X is letter assigned to your flash drive. (Should be the same letter as in Step 4).
Type "Exit" or simply close the command prompt session.
12) Now mount the ISO image of Windows 7.
13) Using Windows explorer, copy
all the contents of the Windows 7 image, from the mounted drive (Copy) to (Paste) the flash drive.
Your Windows 7 bootable disk is now ready!
Dont forget to change the boot sequence in BIOS or go to boot menu after the BIOS is loaded to select USB as your first boot device.
Enjoy Windows 7!
