DVD drive not found issue in windows 7

In some cases your DVD drive may not be found by Windows 7, even if it's visible in the BIOS and using the standard driver.

The standard solution here is to run REGEDIT, and navigate to


then delete both UpperFilters and LowerFilters in the right-hand pane (UpperFilters.bak and LowerFilters.bak entries can be ignored).

If its not working you can try resetting the drive letter .To do that,

Go to Start, type Disk Management and choose the "Create and format hard disk partitions" link. If your optical drive is visible here then right-click it, select Change Drive Letter and Paths, click Change and choose a new letter. If the drive is now visible in Explorer, then repeat the process to change the drive letter back; if it's still not visible, reboot and it should appear.

Today when i was installing windows 7 and the setup was just started i found an error- 'cd/dvd driver missing'... i have already format the c drive so System can not even boot up... please help me out of this trouble.. thank you!

Reseat the CD/DVD drive. Reboot and go into the BIOS setting to see if the CD/DVD drive is detected.
If not then the CD/DVD drive is faulty and needs to be replaced.

my dvd rw is not working.. i mean.. its not reflecting on my pc..

1) Computer off, and unplugged from power.

2) Computer on a table open the computer case

3) Observe Anti-Static Precautions.

4) Unplug the power cable (15-pin), and the data cable (7-pin) to the DVD-R/W drive.

5) Press the Power On button in, and hold it in for a count of Five seconds.
Let go of the Power On button.
Do this procedure TWO more times.

6) Plug the power cable, and data cable back into the DVD-R/W drive.

7) Close the computer case, and plug the computer back into power.
WAIT 1 minute, turn the computer on.
After Windows loads you should see a pop-up, "Found new hardware", and perhaps another one, "Found XXXX DVD-R/W optical drive"

Number 5 above clears the CMOS Error Codes out, and resets BIOS settings back to the factory default settings.
Unplugging the optical drive, (DVD-R/W drive) ,and performing number 5, kind of slaps BIOS around, and makes it recognize the drive is attached, and also Windows.
Makes Windows match of one of it's thousands of generic drivers for the DVD-R/W drive.

I have recently purchased a new HDD (I now have 2 Hitachi P7K500 HDDs) and built it into my system. I have first formatted the HDD I already had, then configured my BIOS for use of RAID 0. My mobo (MSI K9A2 CF-F) btw has an on-board RAID controller which supports RAID 0, 1 and 0+1. (I changed the RAID setting in the BIOS from value IDE to value RAID. This triggered the RAID BIOS to launch on startup, so I need to have that selected to run RAID.) That all went well. Then I decided to reinstall my OS (Windows 7 Ultimate 64-bit) again using my LG GH20N DVD burner/reader, so I used the same drive and disk I have used successfully before. (I have installed Windows 7 like 5 times on that PC) However, during installation, when normally the window asking you on which partition you wish to install Windows would pop up, I get an error message, 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." This never happened before...I decided to google for a fix, but found nothing. (I found solutions for people using corrupt ISOs (reburn) or using old DVD drives (buy a new one), but the ISO I burned is OK, because it worked fine when I didn't run RAID, and my DVD drive also worked without running RAID. And the RAID array is the only thing I changed in my hardware configuration. (I even disabled RAID, and lo and behold, the setup ran fine!) Sadly, there were no fixes involving any kind of RAID. I need you to find me a driver that will fix this error message, so I can install WIndows 7 on my RAID 0 array. I can burn the driver to a CD-R or copy it to a USB stick, so that won't be a problem. Here's my specs again: Mobo: MSI K9A2 CF-F DVD drive: LG GH20N Windows 7 Ultimate 64-bit Thank you already, Yannick Verhoog.

1. If you are just setting up your computer to have an a regular HDD and Backup HDD, i would think you should be able to set that up by booting onto your computer regularly, go to start, then into My Computer and right clicking on the HDD you want to set as Raid 1.

But if just want that other HDD for Space on your computer, all you had to do was plug it in and there you go... extra space.

Now if your installing windows 7 on the other drive i would find that pointless because you already have it on your first drive unless your putting 2 operating systems onto your computer.

Hope this helps.

Windows 7 Beta has deleted my DVD drive.

Do this to be sure that your dvd drive is still being recognized by your laptop. Turn on your laptop and go into your BIOS. Once your in there look to see if its listed in there. If it is then you know for sure that the laptop is recognizing it properly and that its a windows 7 issue. If the dvd is not recognized in the BIOS then what you need to do is with the power off. Take out the dvd drive completely and reseat it back into its slot. Then turn the laptop on, go back into the BIOS and see if its recognized in the BIOS now. If its still not recognized in the BIOS then that means the dvd drive is bad and would need to be replaced. As far as drivers are concerned and that you verified that the dvd drive is recongized in the BIOS, you may not be able to get drivers because windows 7 is not out for the public yet and drivers may not be available, you can always check the manufacuter of your dvd drive and go to there website to get drivers but since windows 7 is not out yet to the public your chances of getting a driver for it are slim.
