    "A required CD/DVD device driver is missing" msg when installing Win7


    Hi there,

    I was wondering if any of you could help me out. I have a Dell XPS 15z L511Z laptop (64 bit, Windows 7, 500GB hard drive, 6GB RAM). Two nights ago, I was factory restoring the laptop to its default settings, when partway through, the screen flickered a couple times, and then restarted with a message saying

    “BOOTMGR IS MISSING
    PRESS CTRL+ALT+DEL TO RESTART”

    Weird… It’s not doing anything. I unfortunately don’t have the DVD’s for the laptop, except for one driver disc. I popped it into the laptop, and it didn’t even read the disc – it just spit it back out. Tried it a few more times, and nothing doing. I didn’t want to force it in, so I figure that wasn’t working.

    I downloaded an ISO copy of Windows 7, and put it onto a bootable USB key, and changed the boot sequence in the BIOS so the USB key loaded first. Thankfully it did… however, when I click on “Install Now”, a window pops up saying

    “A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.
    Note: If the Windows installation media is in the CD/DVD drive, you can safely remove it for this step”

    Since my CD/DVD drive doesn’t seem to be working, I’m not really sure what I should do here.
    I’ve read up on this topic today, and a lot of people have been suggesting to switch the USB key into a different port, but that hasn’t done the trick for me.

    Really looking forward to somebody helping me out with this. It’s been a frustrating couple of days to say the least, I just want to install my Windows and move on.

    NOTE: It doesn’t matter to be whether or not the stuff on my hard drive remains intact. I had like 3 .mp3’s and a few pictures on there, so keeping the data on there is not a big deal!

    Not sure what you used to put the iso file on the flash drive with, but.......

    Try Rufus or Wintobootic, they both work perfectly

    Thank you for your help, it's much appreciated.
    Just to confirm = the USB key that I'm booting from, should it be formatted as FAT32 or NTFS?

    Fat32, but that should not matter as the program will format the flash drive when you burn the files to the usb stick.

    Personally I like Wintobootic, it`s so simple.
