How to install Windows 7 from USB drive (step by step guide):

Step #1: Creating bootable USB drive
 1. Satrt UltraISO (V9.3 or newer version, < download here >)
 2. Choose ‘File’->’Open’ from main menu and open ISO file of Windows 7, for example “d:\ISO\WIN7_DVD.iso”; You may also open the original DVD by 'File'->'Open CD/DVD' from main menu if you have not an bootable ISO
 3. Choose ‘Bootable’->’Write disk image’ from main menu
 4.Insert the USB drive you intend to boot from
 5. Choose proper “Write Method”,USB-HDD+ is recommanded
 6. Hit “Write” to get a bootable USB drive
If no errors occured in the above process, you should now be all set to boot from USB and install Windows 7!

Step #2: Configuring the BIOS of your computer
 You should now reboot and go into the BIOS configuration to boot from USB. Instructions for doing so wildly from system to system, but generally entail the following:
 1. Reboot the system.
 2. While booting (before Windows starts loading), get into the BIOS configuration screen by hitting something like F1, F2, Delete or Escape. Hotkey instructions are generally provided on the screen.
 3. Go to the section that contains your boot devices.
 4. With your USB drive plugged in, the USB drive should be listed. If it isn’t, your system might not support booting from USB. Assuming that it is supported (as is the case with virtually all modern hardware), promote your USB drive to the primary boot device.
 5. Exit from the BIOS configuration, saving all changes.
If you’re completely new to BIOS configuration, < BIOS for Beginners > over at Tom’s Hardware might be a good primer. Be aware though, that you can seriously screw up your system by providing incorrect settings!

Step #3: Booting and setup Windows 7 from USB
 Assuming that you properly configured your BIOS and your USB device supports booting, Windows 7 setup program should now load, you can now continue to finish setting up Windows 7 from USB drive. Depending on the speed of your USB device, this may take a while.


Note #1: If it isn’t working, then double-check the following before making a scene:
  • Is your BIOS properly configured for booting from the USB disk? (Is the USB device listed and does it have top priority?)
 •  Have you correctly prepared the USB disk in step two? (Restart the procedure.)
 •  Does your USB stick properly support being booted from? (Try another one!)

Note #2: The above guide works with Windows Vista/Windows 7 only. For Windows XP with SP2 or SP3 please refer to another guide at <;f=2;t=2440 > .

2. Choose ‘File’->’Open’ from main menu and open ISO file of Windows 7, for example “d:\ISO\WIN7_DVD.iso”
3. Choose ‘Tools’->’Write CD/DVD image’ from main menu
4. Hit “Write” to get a bootable CD/DVD

I try the above steps and it gives me " the number of devices 0"

This is a Vista/Win 7's UAC related problem.
Please right click on desktop icon of UltraISO, choose 'Run As Administrator' from popup menu, then try again.

This is an excellent alternative to the long, drawn-out, command-line-intensive methods for putting Win7 on a USB key that are out there!

However, does this procedure work for other OS's too?  (Vista, XP, etc)

Please explain how to write to one partition on USB HDD. It seems it wants to format entire disk, not only the selected partition.

CLick on 'Xpress Boot' button and choose 'Xpress Write' from popup menu, active partition of your USB HDD will be selected automatically.

Wonder if anyone can help.  I followed the instructions carefully, and Im sure I did them all right, but when I went to boot it, I got an error that starts with " Windows failed to start.  A recent..."  and ended with "an error occurred while trying to read the boot configuration data"  File Boot\BCD.

Can anyone help?  I didnt install new hardware.

I am a newbie to the forum and have just purchased UltraISO. I want to write an ISO image to a flash drive. First opened the image then from bootable I selected write disk image but there is only one output drive showing, which is a large external USB drive.

Despite the fact I have the flash drive inserted in and was able to format it through Windows 7 Ultra it is not showing in UltraISO. Why not?

Hi muffybean, please click right button of your mouse on desktop icon of UltraISO, choose 'Run as administrator' from popup menu and try again.

I have followed all the correct steps to make a bootable USB flash drive.  When I go to "write disk Image" and I click on "Write" it doesn't allow me and a error code shows up that says "you need admin privileges to run this operation".  What do I need to do in order to get those privileges?

The simpler way to install Windows 7/Vista/XP from USB is FlashBoot utility.
It automates everything.

I tried many times but during writing it changes the folder names.

Posted by rope on Jul. 22 2011,10:51
watch this one < >  i make this one today

**when you downloated the hirens boot cd you only have to extract the iso file  nothing else..
**then you open ultraiso and select the tap file ..load the iso hirens boot cd ..
**hit tap bootable and select write disk image ..
**select now your usb stick an format ..if nessecary..
**select  USB-HDD+
**hit write you have to wait ..
when burning is done you see the mesage burning succesfull..
do a control and open your usb stick

I just got a new software called Portable Drive. Does it work that way? I am just not sure if it works in OS.
