Don't panic. Your computer should be ok.
Rescue your files
First of all, you said you were upgrading to windows 10. If you didn't backup your personal files (like text documents) before upgrading, be careful since installing Windows from disk may erase them (if you choose to format or repartition the disk)
If you didn't erase the disk yet, your files should still be on the disk. Files on
Desktop and in
Documents folder are normally stored in
c:\users\(your_user_name)\. Try this guide if you need them. You may run into exact same problem you already described however - see below.
Fix the "missing driver" problem
In your scenario options 1,3,4,5 will not work because you were in the middle of upgrade process and it failed. You need to reinstall the system to make it usable again.
The real problem is the error:
A required CD/DVD drive device driver is missing.
What it windows DVD trying to say is that it cannot find a driver file that would allow your DVD-drive to function.
There may be different reasons why this could happens:
- Windows cannot find a driver for your USB-DVD drive. I don't think this is a likely case since you somehow booted from it.
- Windows cannot find a driver for your USB-port. If it is a USB 3.0 port (blue color), try connecting the drive to USB 2.0 port (colored black or white).
- If the DVD disk you are trying to boot is not an official windows installation disk, or is for another computer model, or you downloaded it somewhere and burned it, it may not be compatible with your computer. Try a different disk.
- The drive just cannot read the required file off the disk. Your disk may be dirty. Try gently wiping disk surface with a clean cloth that does not leave any threads behind, such as one for cleaning monitor screens or glasses. Do not use cleaning liquids as they may damage the disk and the drive.
- You drive may be faulty. This happens even if it always worked and you last used it ages ago. Try different drive if you can.
- If nothing helps, see next section
Create a bootable USB
I suggest you abandon the DVD and write Windows setup onto a USB-stick flash drive.
You will need a working computer with internet connection.
- Find a USB-drive (at least 8GB should be enough)
Copy any files off your USB-drive. Following steps will erase all files from it
Download Windows installation file from this page
- If you don't already have a Windows 10 license key, you will have to download whatever version you have a valid license number for (select from the top of the download page). Upgrading from Windows 7 and 8 to 10 is no longer free now.
- "Windows 10 N" is for Europe and "KN" is North Korea
- Please remember which version (32 or 64 bit) was installed and licensed on you computer. If yours has a license label on the bottom, refer to it.
Navigate to this page. Download the tool and refer to usage guide on that page.
- You will need to do a
clean installation, not
upgrade because the latter may fail if the system in question is not working properly before upgrade as is in your case.
Insert USB-stick in your computer and turn it on. If it will not boot from USB, read you computer manual on how to get into a boot menu. Usually you need to press F8 or F12 upon boot several times.
Install Windows normally. It should work.
If you still get a same or similar error, update your quiestion with exact model number of your computer (see stickers on the bottom) and windows version you are trying to install.
