Booting Windows 7 from a USB Drive/External HDD?

I recently built myself a new desktop computer and downloaded the Windows 7 OS onto my external HDD and a flash drive and tried to boot up the comp from there. I went into BIOS and made them both priority after the other didn't work and i'm still getting no results. I downlaod Unetbootin and it brings me to an error screen with a 10 second count down and it tells me to hit tab. Anyone know how i can get this to work and stop getting error messages? i

    What do you mean by "downloaded" ? From where, and how?
  2. My friend had it on his computer and sent me the file and I put it on an external HDD and a USB.

    "It" what.....

    You have your own license key for this? You can't use your friends.

    Well I hope your friend has an actual Retail disk and just made an ISO for a faster install through USB. Otherwise it's most likely a cracked version of windows and you will receive no support from me. But if it is a legit version of windows, you have to make that device you put it on Bootable. You cant just drag and drop a file and load it. You pretty much have to reformat that particular drive/usb to be read as a bootdisk. Which there are programs that will do it, it just takes forever.

    But first before we go further. How did your friend obtain this file?

    And if his friend does have a cd key for that disk, he can use it. He just has to call MS and they issue a new one.
  6. Guys I say again stop torrenting and downloading pirated software- if you are caught you'll have to pay a fine that is more than the price of the full version software.

    Indeed. Even though Microsoft really doesn't care, unless you're running a business, if you download the wrong file or don't have a friend with a retail disk than can make a legal "Backup" of the disk, then you are putting yourself at risk. For example, if your friend downloaded that cracked windows 7 from a site, it could have hidden viruses/backdoors on the installation file that will instantly infect your computer. Also, there could be a "Tracker File" embedded within it as well. So all in all, be safe and just buy the disk or only accept Retail Backups. Windows 7 is only like 60 bucks now anyways. And windows 8, if your hardware is compatible, is the better choice now that they fixed a lot of issues with 8.1.
