    What reply would you like? Nobody has responded with what I need. The tutorial doesn't work for me. I don't have Windows 8 at all on my HD. My Bios doesn't have many options. I'm lost.

    After I select to start instalation, I get the following message almost immediately:

    "A required CD/DVD device driver is missing...."

    I'm installing from a DVD, so it's able communicate with the drive and read the DVD.

    I tried my Win7Ult32 DVD and I have downloaded another copy from msft.digitalrivercontent.net, same results.

    The DVD drive is an HP "Super Multi DVD Rewriter", model GH82N (A2HH).

    Does anyone have any clues as to what's tripping me up here?

    Thanks,

    Chris

    Edit: My old Windows 7 64 retail (2009) give the same results.
    I'm having the same problem, booting using an ISO image on a USB, managed to get through the bios problems to then come up against this exact problem. How did you fix it?

    If Using a USB Pen drive on a PC with a UEFI BIOS.
    USB Pen drive need to be formatted to FAT32 as in
    UEFI Bootable USB Flash Drive - Create in Windows
    Take note of Step 11 for Windows 7.
    Also you will need to use a USB 2.0 port, as there are no USB 3.0 drivers in Windows 7.

    Hi, thanks for this. I have been using (both) 2.0 ports and I was pretty sure I did step 11 last time around but I went and remade my bootable USB this morning and the same message comes up when the windows 7 "install now" button is pressed there is a pause as set up is starting and then this:Click image for larger version

    @ Andrew92

    1) Using a USB3 port.

    2) Bad installer write.

    Where do you buy your DVD & Full Retail Windows 7 Product Key from?

    Thanks again, like I said I've already done the bios faffing earlier
    This final hurdle was also in the bios, I had to disable the AHCI option in the bios (rather than change it to something else like suggested earlier which gave me a problem trying to find it). Once I'd done that and rebooted it worked fine. No more windows 8, Huzzar!!
    Thanks for all the help, this tutorial has been fantastic!

    Hello!

    Can someone help me?

    I have an interesting problem with my girlfriend's laptop..... (SAMSUNG NP350V5C) She bought it with preinstalled WIN 8 but She doesn't like it.
    I thought I can downgrade the OS to WIN 7 without problems...... I was wrong.

    I did it with the similar method than You wrote it. But I think I did a big mistake because I didn't KNOW what is uEFI..
    I just wondered where is the f..kin BIOS, why cannot open it. All the same.... I moved out the laptop's HDD to my usb mobile rack and with my PC I formatted it. Of course I deleted all partitions. I put back the HDD to the laptop. After this I could open the BIOS but the UEFI is disappeared. I didn't care. I set the secure boot to disabled and the os mode selection to CSM mode. After this I installed the WIN 7 without problem. I was happy till the first auto restart during install. I noticed the next: Since I deleted all the partitions from HDD by an other PC, the laptop has only BIOS without uefi. But not is my real problem.

    The real problem is the Win 7 cannot boot automatically. Only if I use boot menu and manually choose the HDD or use boot override from BIOS. (The HDD is set to 1st priority in BIOS boot option.)I tried to re-install 3 times the OS but nothing changes.

    Is there problem with BIOS or what???? I hope you can help me. Thank You!
