Windows 7 install stops at "CD/DVD driver not found"

When trying to install Windows 7 with boot camp, all goes well until it stops and gives me the "CD/DVD driver not found". I have a mid 2010 Mac Pro with a 500 GB SSD drive. I have burned a DVD at 1X from a iso file.
Thanks

Can you verify the MD5/SHA1 of the DVD with the ISO using OS X 'openssl md5' or the M$ FCIV tool? The source of your ISO should be able to provide MD5/SHA1.
OS X Example
openssl md5 ~/Desktop/GRMCPRXVOL_EN_DVD.cdr
MD5(/Users/MyName/Desktop/GRMCPRXVOL_EN_DVD.cdr)= 977f4f0f1400be91855789213e07b031

"valid dvd driver not found"

I have a Powerbook G4 12"--has always worked without problem.
However, this am tried to play DVD--got the error message "valid DVD drive not found". No driver seen in system profiler.
There is no CD or DVD stuck.
Have gone through the workarounds suggested in discussions--open firmware ejects etc...
Has anyone found a solution other than paying $500 to replace the drive?
Many thanks

First see if the issue is user or system related. Go to Apple menu -> System Preferences -> Accounts and add an administrator account, and log into it after logging out from the Apple menu.
If that doesn't work, try locating a preference in the System/Library or Hard Drive -> Library for com.apple.dvdplayer and removing it. Same for cache files.
If it still doesn't work, try VideoLan Client:

Cd/dvd drive not found, can I format hard drive with an external cd/dvd drive. If so how?

My cd/dvd drive quit working and is not found in device manager so I purchased an external cd/dvd rw.

Can this be done with external cd drive, if so how do I boot from it? presario v6000 laptop windows vista 32bit os.

Restart the notebook >> start tapping F10 key >> go to configuration menu >> Boot Order >> select the Ext DVD drive as 1st boot device >> save and exit >> Insert the recovery disc >> restart the PC >> press any key when prompted >> follow the instructions..

Force eject: Initialization error [-70012] Valid DVD drive not found

Back in December I had an issue with a DVD from NEtflix that was sucked into the black hole of my G4.
No force eject protocol worked, must have tried at least 1/2 dozen.
Come to find out, my drive works fine with some DVD/CD and not with others.
The one fix on the web that works is an obscure one that I found.
Restart computer and then insert a credit card into the drive slot, slightly putting pressure upon the spinning disc while pushing the eject or track pad until eject initializes.
So, while I can get the disks out my question is: Why do newer DVD/CDs fail to initialize within my drive...
is it an outdated optical thing?

Does the drive make any noise during power up? You may have had a drive fail completely. One thing to do is check System Profiler and look at the ATA info under Hardware and see if it finds the drive. If it is not found there, the CPU is not seeing the drive and the drive may be kaput.
You should be able to find information on ifixit, like at
http://www.ifixit.com/Guide/Repair/Installing-PowerBook-G4-Titanium-DVI-Optical- Drive/100/1
to see how to get the optical out. There may be instructions on getting a disc out of a failed drive there, or you may have to do a Google search for instructions, as I know they are out there and relatively simple to handle.

Initialization error [-70012] Valid DVD drive not found

I inserted a dvd and it has disapperared into the G-4 black hole.
No icon to eject, and DVD app will not open.
Tried to force eject with BFH, I mean restart while holding trackpad, with no reaction from drive.
Feedback??
With Thanks.

Initialization error-valid dvd drive not found-no icons, no disk eject

My mac mini is giving me a hard time. Actually, ever since I got it over 5 years ago, it's been a bit of a headache with the DVD/CD drive.
I've even had the drive changed once under warranty. Anyway, I'm trying to upgrade to OSX 10.6.3. For that, I need to put the CD into the drive.
Right now I have my start up disk in the drive as I tried to do some repairs to the disk before I installed the new OS.
But as in the past, my disk is now stuck in the drive. There is no icon of the CD on my desktop. My DVD player program says that no valid DVD drive has been found. I've tried every way I know to eject the disk as this has happened to me before. I've reset the SMC by shuting down, unpluging the power and other cables. Waiting 15 seconds and even a few hours to see if it made a difference. Plugged it all back in and turned it on. The CD whirls around in there as I can hear it, but then nothing. No icons, no nothing. It's as if I don't even have a CD/DVD dirve on the computer at all. I've tried starting up holding the mouse button down before start up, after start up, durring start up... nothing. I've tried starting up from the disk by pressing C. Momentarily (a fraction of a second)I get a little question mark where the grey apple is supposed to appear but then the grey apple appears and the computer starts up from the hard drive and not the disk. I've even zaped the PRAM a few times for good measure. I just spent $20 on Snow Leopard to install it. I really don't want go to the repair shop again and spend more money on something I already fixed once. Any suggestions or further tips would be very welcome and appreciated.

Whew, sounds like maybe Logic Board problems!?
Does iTunes Eject Disc work? (I doubt it, but...)
Maybe Double backed tape on a credit card to extract it???

A valid DVD drive not found (error -70012)

Hi.
I get this message when I try to insert a DVD or start the DVD Player app:
'The was an initialization error: A valid DVD drive could not be found [-70012]'
It won't allow DVD to be insert, they just kind of hit a buffer. There seems to be no power to the DVD drive.
Just happened one day.
Macbook Pro running 10.6.8
Any ideas?
I'd try to get an appt at an Apple Store near me but they are all booked up!!
Thanks

I can only think of two possible reasons. 1. The optical drive is dead. 2. The DVD you put in for some reason went in at an incorrect angle, and jammed something in the drive mechanism.
If you buy this reasoning, you could try to wiggle the DVD. I would use the edge of another cd, inserted about half an inch (one cm) till it touches the one inside, and see if you can get some movement up and down of the one inside.
Needless to say you would be doing this at the risk of further damaging the optical drive as well as the DVD.

Valid DVD Drive not found ...

Greetings All,
I have a Power Mac G4, and lately it does not find my DVD drive. The error message I recieve when starting up DVD Player is: "There was an initialization error. A valid DVD drive could not be found {-70012}" I have another LaCie drive connected to the computer, but I want to use the internal drive as well.
Any help?
Thanks,

Boot Camp: Installing windows - CD/DVD driver not found

Hi all,
I have a late 2012 27" iMac - no optical drive. Running 10.9 - Mavericks.
Using Boot Camp Assistant I have created a BOOTCAMP partition, and a bootable Windows 7 USB key.
When I boot into the USB, I can proceed to the point where I click "Install Windows". The next screen tells me there is a missing CD/DVD driver. Well no kidding - my computer doesn't have one.
I've tried removing the USB key and putting it in a different USB port at that step - no change.
I've searched all over, but 99% of the similar problems are from people installing from a disc - I'm installing from an ISO on a USB key.
Any ideas?

Can you verify the MD5/SHA1 of the DVD with the ISO using OS X 'openssl md5' or the M$ FCIV tool? The source of your ISO should be able to provide MD5/SHA1.

CD/DVD Drive Not Found

My Pavilion dv5 no longer finds the CD/DVD Drive in My Computer. The Device Manager shows it and notes all is well. However whatever I put in the drive spins up then stops without anything showing on the screen. I have checked everything I know, uninstalled, reinstalled, updated bios. Any help out there?
This question was solved.

Problem solved. I opened Control Panel, Admin Tools, Computer Management, Disc Management, right clicked on the unnamed drive and gave the explicitive a Drive Letter. Appears to be working now. Thanks for your assistance, I appreciate it. Any ideas on how this happened would be appreciated.

Why do I get a boot drive not found error only when laptop lid has been closed?

I've got a HP Mini 210 P/Number: VX818EA with Windows 7 Starter.
It works fine when turning on after shutdown, but when I've put it to sleep by closing the lid it won't 'wake up', and I get a blank screen. On restarting the computer I get a 'boot drive not found' error, (3F0) which can be resolved by following the steps on this page: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01443463&tmp_task=solveCategory&lc=en&dlc=en&cc...
I've run disk check etc as suggested on that link, no errors are found, but nothing seems to resolve the problem more than temporarily. Seems odd that this only happens if I close the lid (sleep mode with the lid up is fine, doesn't crash the computer).
Can anyone advise?
Thanks

Hello,
Very strange, can you go to BIOS and reset the setting " By Default " ?. How did you check the disk ?
This is an unusual probleme Hp Mini 210 . And notice me after your reset the bios settings.

Network controller& USB controller driver not found and wifi not working

hello I Purchased HP 15-ac025TX (M9V00PA) Notebook laptop . i have installed all driver from HP site here is the link  http://support.hp.com/in-en/drivers/selfservice/HP-15-Notebook-PC-series/7771404/model/8326084#Z7_3054ICK0KGTE30AQO5O3KA30R1  but still netwok controller driver not found also wifi not working i installed blutooth drivers too . I am using window 7 sp1 (32 bit) For network controller device ID is PCI\VEN_14E4&DEV_4365&SUBSYS_804A103C&REV_01 secondly univeral serial bus driver(usb) controller not found i installed all drivers from above link also update windows but still no solution hardware id of usb controller is PCI\VEN_8086&DEV_9CB1@SUBSYS_80C2103C&REV_03  and last i am unable to download AMD/Intel Switchable High-Definition (HD) Graphics Driver. the download link not working KINDLY RESOLVE THE ISSUE THANK YOU

Update: While the driver I knew would work has not shown up yet, I did some detective work and explored some other broadcom wireless card driver folders from some HP links, and I found one that should work for you. While it says it is for HP desktop PC's, they put the exact same wireless card form factor in a desktop PC that they do in a notebook PC. I see no reason why this driver would not work, since the setup information file contains the same hardware ID that you posted. Here is a partial copy and paste of the driver setup information file and you can see the hardware ID you posted is supported by this driver.  x86 - Win7
