  1. ISO too large for a DVD+R disc


    I have an older PC that will not boot to USB. It did have Windows 10 on it. When I try to burn Windows10 to an ISO from Microsoft, it's too large for a standard disc. Is there a tool that will "slim down" the ISO?

  2. DVD+-RW drive suddenly stopped recognizing blank DVD-R discs

    Thank you for your help, Andre. I appreciate that it was so prompt!

    My system is a Dell Inspiron 5558.

    First step: Running Troubleshooter in Hardware and Devices and then restarting.
    Outcome: No change. The drive says to insert a disc, even though there is a brand new on in the drive.

    Second step: Open Device Manager and update the driver for the DVD drive.
    Outcome: No change. Using the option to search the internet for the most current drive, Microsoft says the best driver for this device is already installed. FYI - the DVD drive is: TSSTcorp
    DVD+- SU-208GB

    Third step: Open Administrator:Windows Powershell and run the regedit.exe command then restart.

    Outcome: No change. The drive does not recognize a new/blank DVD-R.

    Fourth step: Check out the suggestions at groovypost.com. Remove and reinstall the IDE/ATAPI drivers (ATA Channel 0, ATA Channel 1, and Standard Dual Channel PCI IDE Controller).

    Outcome: When I set the view to "show hidden devices" and expanded the IDE ATA/ATAPI controllers, there is only one listed: Intel(R) 9 Series Chipset Family
    SATA AHCI Controller. I didn't do anything because I wasn't sure about uninstalling that driver.

    So, bottom line, nothing changed. The problem of the drive not recognizing a new DVD is persisting. The only thing that changed from four days ago, when I burned about 8 DVDs, and now, is that I ran out of the DVDs I was using and bought a new batch (identical
    brand and type to what I had been using - SONY DVD-R). I bought a second batch of a different brand - Maxell DVD-R - and those don't work either.

    I don't believe it is a hardware issue because when I plug in an external Dell DVD+-R drive, it also doesn't recognize the discs.

    This is really bumming me out. I am in the middle of a project and I can't finish it!

    Any suggestions would be appreciated! Thank you!!

    Cannot burn ISO to a DVD-R disc

    Hello all, I was trying to burn an ISO file to a blank, new DVD-R disc with my external Asus SDRW-08D2S-U recorder,and I tried a few ways do that but none of them have succeeded. I firstly tried to burn the disc with the Windows 10 built-in ISO burner,but it showed some errors. Then I tried a few 3d party ISO burners,but no one did the job. Now my disc is completely destroyed. I will buy a new disc,but please tell me how to successfully burn it. By the way,the ISO file I want to burn is the Ultimate Boot CD. Please help me. Thanks to all in advance. My Windows version is : Version 21H1 (OS Builed 19043.1320)

    misidentified dvd+r discs

    windows identifies my verbatim dvd+r 4.7 GB 16x discs as dvd+rw discs. this causes every authoring program to attempt formating the discs. I have also tried memorex dvd+r with the same result.
