How to install Windows 7 from USB flash drive

Good Grief! is the better expression. First you have to boot live from a 7 dvd or installation not run the 7 installer from within ubuntu.

The guides posted so far take you through the entire process step by step for seeing a custom install of 7 on a separate NTFS primary partition. For setting up a dual boot of ubuntu with 7 that's where a 3rd party program called EasyBCD will help when seeing the 7 install made the default OS.

As far as UltraISO you run that on a Windows machine where it will extract the setup files in order to create a disk image you then see written to a flash drive. As the screens showed earlier UltraISO will prompt you with the warning about overwriting any files remaining on the flash drive used as the installation key.

Once that is made up you boot from that live as you would the 7 dvd or any live distro to run the installer as well as selecting the primary where the 7 installation will go. The MS tool was provided for those who bought and downloaded direct from MS not for creating a live usb install key from a 7 dvd.

By using he format option seen in UltraISO that will be Fat by default while it will still write the disk image to a flash formatted to NTSF. Once 7 is up and running you can use the NeoGrub option found in the EasyBCD program to see the entry for ubuntu added in if you are planning a dual boot between the two OSs. Othewise the drive tool provided with the 7 installer can even delete if necessary the ubuntu root/swap partition(s) and create the new MS primary(NTFS) for 7 to go.

Review the guides already posted by Bare Foot Kid. If you follow those you won't get lost!

ISO Files or ISO image? You can create an image from the files and then see that written to a flash drive or burned to disk. UltraISO or the native option now seen in 7(once on for you there) can burn the image to disk while any iSO or even other types of disk images can be written directly to a flash drive.

Note you will need at least a 2gb flash drive to work with. While the files won't take up 2gb anywhere the process of writing will use the capacity of the drive. Here I tested this ar first with the 7 RCs mostly for various custom installs and later checking things with the retail 7.

Looking back at the second image posted before that shows the ISO for GParted there but illustates how any ISO image is opened for viewing before the write to flash drive or burn to disk is seen.

With all files in plain sight in the upper portion as seen as there for the setup files you are ready to use the make image option and then see the image written afterwards or try a direct write to flash drive while viewed.

The write itself is seen in a flash since that only takes a minute at the longest. Well depending on drive as well as the system used anyways! Do you have a flash drive onhand or still have to get one?

You can easily find out if you have an image since that will be only one file ending with the iso file extension if already seen in disk image form. If the drive presently has any files on it you want to keep copy those off first into a folder for safe keeping and format the drive using the option for that in UltraISO. Even if reformatted with the right click option in Windows programs can be fussy and still want to see that done with their own option at times.

You may get away with simply browsing to and clicking on the iso file which then opens it for viewing and selecting the "menu bar>Bootable>Write Disk Image" option followed by starting the write which acts as the run option on the popup screen. That's when the confirmation prompt will then appear and ask if you want to overwrite the files found.

You can opt to reformat to NTFS if not Fat 32 since the program will still write to either file systems. Once you have a good working install of 7 seen you will want a repair cd onhand. The option to burn a repair tools cd for live repairs that may come up is found in the Control Panel>Backup & Restore.

While the flash drive can still be used a live cd usually works best when not running 7 on a netbook which comes without any. The option in the CP will automatically burn the correct 32 or 64bit flavor for that. Even with the 100mb Boot, BCD store, repair tools partition created if seen a live repair tools cd is good to have onhand.

I think this needs to be marked as unsolved-able.
