In my previous post we discussed about installing Windows XP using thumb drives. The post can be found here, http://delphintipz.blogspot.com/2011/07/how-to-install-xp-os-using-pendrive-or.html .
In this post we will talk about installing Windows 7 and windows vista using thumb drives.
To make your pen drive bootable you need to download and install the latest version of Ultra ISO , and you must have windows 7 or windows vista dvd image in .iso format. If you have a dvd with vista or Windows 7 you can make .iso image using ultra ISO...
Open Ultra ISO application by clicking the shortcut(If you are using vista or windows 7 right click the shortcut and select run as administrator). Open your windows 7 or vista .iso dvd image through file menu of Ultra ISO.
Once you opened the .iso image select Bootable>WriteDiskImage
Select the USB drive you want to make it as bootable. Click format, and format the drive using ntfs partition. Then click on write to begin the process.
Once the process is completed, you can remove the drive from your computer and start installing with that pen drive.
Hope this helps...
