Hey, been trying to follow and figure out how to boot from USB. Here is my situation. I can ask in another forum if needed, but I am guessing that some pointers might get me to where I need to go. Hi, Here is my deal: I have an HP m490n computer. The registry is messed up, and the restore files on the hard drive are messed up too. So I downloaded a copy of Windows MCE 2005 (same as my computer) because I don't want to pay HP for a copy of the OS that I already purchased. I have HP Windows MCE 2005 Restore as an ISO, and have also mounted via Daemon Tools Lite (both on the computer I'm curren't using). I don't have a DVD burner and the OS is too big to fit on a single CD. [THE FOLLOWING INFO IS FROM MY POST ON USBOOT.ORG OR COM OR SOMETHING AND ISN'T REALLY PART OF THIS DISCUSSION, BUT I WANTED TO ADD IT TO SHOW I AM TRYING BUT CAN'T FIGURE THIS OUT ON MY OWN] I want to boot from a USB flash drive (thumb drive, pen drive, etc). The first time I tried to do this with USBoot the directions said you had to put the USBoot folder in the root directory of the OS you want to make bootable to your USB stick. So, I copied the mounted ISO and USBoot to the USB flash drive. I got through phase-I and phase-II, but at phase-III it said it couldn't continue because the drive wasn't empty. Obviously, putting the OS on the flash drive is incorrect. I can't add USBoot to the mounted ISO. Should I add USBoot to the ISO and remount? Or, what is the correct procedure?? Thank you.
