Can't find DVD drive under My Computer and regedit fix doesn't work for it

I did a windows recovery using the recovery disk came with the laptop. Then when I tried to install a printer drive, I found that there is no DVD/CD-ROM icon in My Computer. I tried with the regedit fix, but it doesn't work.

Here are the facts I have:
1. In bios, under Boot session, DVD/CD-ROM is listed.
2. When I tried to run the recovery disk again, it always skip the DVD and boot from the hard disk. I did have the recovery disk in the DVD drive, and I set it boot with DVD/CD-ROM in the bios Boot session.
3. I ran the regedit fix several time but still I can't see the DVD icon under My Computer.

Does this mean there is a hardware problem with the DVD drive? Is there something else I should check before I replace the DVD drive? Thank you very much.

    I tried that. But still I can't see the dvd drive. Well, for now I can't even reinstall Windows since it won't boot from DVD drive.

    It turned out to be that the DVD driver connection was loose. By opening the covery, pull out and push in the DVD driver, it is fixed. Thank you for all the solutions.

You may have to check the registry manually and if this will not work, you may have to reinstall windows.

1. click start > run > regedit > ok.
2. In Registry Editor, expand the following registry path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class

3. Under Class, click {4D36E965-E325-11CE-BFC1-08002BE10318}.

4. Delete Upper and Lower Filters. (If only one is availabel, that's fine).

5. Restart system and check your drive again.

NOTE: Make sure to do this correctly or else, system will not load to windows.

If manually deleting upper and lower filters will not work then you may have to backup your files and reinstall windows.

Some windows files deleted in error can i get them back?


Most of it can be recovered with a recovery disk. You should have it when you bought the computer. Or can ask a friend with the same model.
Put the recovery disk in you CD/DVD drive. Restart computer press F2, or delete either to get in CMOS setup. Set the Boot sequence to CD/DVD drive in the CMOS. Save and reboot computer. It should boot from the CD/DVD drive and follow the instructions.
But if this doesn't fix. Try reinstalling Windows. If you are lucky this should repair. But it could also mean it cannot be repaired and you need a fresh install.
Sorry mate and Good luck.

Ok i logged in but i still have no apps or programs in control panel wut so ever. I checked the contents of the recovery disk i created and used once before now its blank help me figure out please!


Which operating system ?
As for the recovery disk with nothing on it it might be a problem with the cd\dvd player
Click start control panel administration tools computer management device manager scroll down cd-dvd rom drives you might see a yellow question /exclamation mark ? ! or a red X right click to update driver You might have to physically unplug the leads for this cd/dvd computer then plug them back in restart your this should activate the found new hardware wizard. If this does not fix the problem it might be a registry problem "you only need to do the following" if you cant see your disk drive in windows explorer Close all open programs Click on Start, Run, and type regedit and press Enter Click on the plus signs (+) next to the following folders HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control Class {4D36E965-E325-11CE-BFC1-08002BE10318} This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column. Upper Filters Lower Filters Upper Filters.bak Lower Filters.bak If any of the above keys shown in step 4 are listed, right-click on them and choose Delete

After deleting the keys, close the registry editor
Reboot your computer
Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone. if this fails to fix the problem

It could be a problem with the lens you could use a liquid type lens cleaner place 2-3 drops on top of a cd/dvd then run it Hope this helps.

How can i reformat my packard bell laptop without the recovery cd?


The recovery cd is just a Pre-Built Windows version that includes the drivers you need for your computer.
If you want to format your pc and lack the original recovery cd, you just need to get a Windows (or other operating system you want) installation CD/DVD, put it on your optical drive and reboot your computer.
On installation, you will be asked what you want to do: Fix or Install. Choose install and check to format your disk.
After installation, if something doesn't work, its because you don't have the needed drivers, so go to Dell's Support Page find your computer, download and install the drivers you are lacking (video card graphics, sound, etc.)
Hope it was helpful ;)

Detects CD but not DVD


Hi Chopadepve,

Please try this method but be more careful during working out on it:

Since your DVD drive reads cd's, but not dvd's It shows that the hardware works fine. Now we need to Edit the Registry to fix this problem.

1) click the start menu
2) click on "run"
3) type "regedit" and click ok
4) go to string key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
5) delete "upper filters" and "lower filters" in the right side window.
6) right click my computer in the start menu.
7) click properties
8) go to the hardware tab
9) click device manager
10) expand the dvd/cdrom drives
11) right click the dvd rom and click uninstall
12) Reboot PC

Windows should automatically install a clean ROM drive after the reboot otherwise Open the device manager window and click "scan for hardware changes". DVDs just read fine if you have the correct DVD decoders.

If no luck then might be DVD read head wiped out.

Regards
ELLIN
