    Flash drive not recognized when trying to boot Win7


    I've created the ISO file and moved it to the 4g drive using the AWESOME guide found here. However, the BIOS doesn't seem to recognize that the device is present. I've done some research and found that some usb drives aren't compatible with the BIOS? I made usb storage the only available boot option and nothing showed up. However when I look at the drive while in Vista through my computer->G: It shows up as a windows system. I've also seen somewhere about enabling "Legacy usb"? I didn't find anything like that. Should I just got buy another flash drive and try again? Thanks. -Zach

    Has nothing to do with type of drive. The option should be there as one of the choices in bios. Sometimes it's obscured and difficult to figure out which one it is. If you want, write them down, boot to Windows and post here with all the choices you have.

    We can tell then most likely.

    An ISO will not run from flash stick in my experience. You need to format the stick Primary in Disk Management, then copy the installer files into the root. I have a 16g stick with my apps/tools and two OS's I keep in folders, then just spill out into the root for booting.

    It will be listed as HDD.

    THere should be a shortcut key (like f10) that gives you a boot menu at startup. It will be there under HDD's.

    Otherwise find it under HDD's in advanced BIOS settings and set it to boot first. But don't disable your main HDD!

    If your computer is older it might need a BIOS update to enable all of this. Look on your manufacturer's product downloads page.

    Can you provide the link to that particular 'AWESOME guide' ???

    There's tutorials, links all over, etc. Which one did you use?

    I'd say to Hang on a bit, before buying another USB stick, until the link is posted...
