DVD drive not detected on vista EDIT: What do I rename registry

RoyceSraphim

So My father has requested that I update his laptop to windows 7. I agree but run into a problem. The laptop doesn't recognize the cd drives because of faulty drivers.

The laptop is a Vaio PGP-6Q6P with a Matshita DVD-Ram Uj-852s and a TGH 7W96VGT.

Updating and microsoft support haven't helped and most of google searching has said to edit the registary myself which I am loath to do because this is not my laptop, its one that my father uses for business.

I ask, is the another solutiuon or must alter the bowels of vista myself?

Now, proper google searching has lead me to believe that I must create a restore point in the registery and finangle around with the upper and lower limit things and either rename them or delete them. This is where I am confused due to conflicting messages. Could someone please elaborate on what I should do?

Doesn't recognize the rom in my computer, and device manager shows missing/corrupt drivers?

start>run>regedit

HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Class

Look for what should be the 6th key down, should be at the very top of a list of about 25 identical registry keys. Click on it, should say DVD/CD-ROM drives at the top. Look for Upper and Lower filters and rename them, then restart.


Basically, yeah, you do need to do some registry editing most likely. If you're not comfortable doing that, check to see if the rom shows up in the BIOS first. If it does, this is going to be the first thing to try.

Screw it, tell me what I should rename the registry.

RoyceSraphim

Okay, I found the upper and lower filter files on the registry, do I delete them or do I just rename them, and if I rename them, to what do I rename them?

First, your father is an idiot for even having you deal with this. Second, you are likewise for even taking this on. Give him the laptop back and tell him to pay someone to do it properly and provide some sort of service guarantee. If this is a business laptop he needs to back his shit up and have it done professionally. Don't start mucking around with shit you know nothing about.

Lastly. why are you not just booting off the disc and installing from there?

RoyceSraphim

Insulting as your language may be, you are true on both points, sir.

The funny thing is that the laptop sees the windows 7 upgrade disk as a boot disk but does not see it through vista proper.

Now, proper google searching has lead me to believe that I must create a restore point in the registery and finangle around with the upper and lower limit things and either rename them or delete them.

Boot off the disc, do the installation from there, it'll install in a different directory leaving the old one in place. Otherwise you can go into safe mode, pull up device manager, find the driver in there, delete everything listed for the optical drives and then just reboot and see if it redetects the drive and installs a proper driver. I am baffled why google is telling you to muck with the registry as optical drives are one of those things that normally 'just works' and has since XP came out. The system should just be using the generic MS device driver.

RoyceSraphim

Ah, youb describe my problem proper, for you see, while the computer sees well enough to launch the 7 disk on boot. I require an upgrade which requires it to be seen by vista, the current siren of me nightmares.

If you still are stuck just delete them. Done it a couple of times on some clients systems works like a charm.

RoyceSraphim

Holy crap, do I soooo hate vista, I had to google a solution to make a system restore point!

Try it now.

BTW, the Grub bootloader will also cause some laptops to lose their CD and/or DVD drives in Windows. Ran into this when repairing a co-worker's laptop. Very, very obscure problem - solution was to replace Grub with another non-Grub bootloader (in that case I used EasyBCD).
