How to instal Vista using USB

hi..if you want to us the USB you need to have a portable DVD drive (if the installer is in the CD)... thank you very much....

USE THIS SOFTWARE AND TICK THE CHECK BOX FOR WIN 7/VISTA AND BROWSE THE PATH OF VISTA SETUP FILES

fell free to contact if any problem occurs

First of all, I have to ask if you have vista install on a USB and is that USB bootable. You can use this program to make the USB bootable. Just save the vista file to your flash drive via the program

Next, you have to enter your bios, hold F2 or F12 at power up before windoes starts. I am not sure how yours looks exactly but you need to find and change your boot order so that you boot from the USB first. Once this is all done, you are on your way. Let me know if you need anything else.
