Windows 7: Can't install Windows 7 Ultimate

21 Nov 2009   #1

Windows 7 64-bit
Can't install Windows 7 Ultimate

I got a studuent copy of Windows 7 Ultimate which I downloaded
an ISO and burned to a DVD-ROM.

When I boot off the DVD it seems okay and starts the install process.

It comes to a screen that says "Install Now" and I click on it and
it comes up with

"A required CD/DVD drive driver is missing...blah blah ms blah"..

I have been working on this for 3 days.

I have read how to boot Windows 7 off a memory key and tried that route.
I get the same problem. I even totally unplug the only DVD-Rom drive from
the power and from the IDE cable and boot off the memory key and it comes up with the same error.

I had read that it could be a SATA driver. I have downloaded the SATA drivers
from the vendor's website and it does not like that.

You think Microsoft would at least tell us what freakin driver it is looking for.
It must know what PCI/VEN and DEV it is looking for. Why not tell us?

I have since downloaded from River something Windows 7 Home Premium 64 and
I am running it without a key for the next month. It ugraded from the Vista
64 just fine but it started the install from inside of Windows. I cannot find
the same type of installer for Ultimate. Just the ISO. Can't run the setup
from th CD because I get an error on SPWIZENG.DLL. From what I have read
you get this eror when not booting Windows 7 from the DVD. Well duh!

Now I have VWindows 7 Home Premium 64 installed I downloaded DriverMax and
copied all the drivers to a folder. I then try to boot from the
Windows 7 Ultimate DVD and I give it thst folder to look for drivers.
There is like 200+ drivers in the folder. I have tried the CDRom drivers
and the Hard drive drivers and some of the chipset drivers and some of the
system drivers. No, I have not tried all 200 drivers. It takes the installer
like 1-2 minutes to think and finally tell me its not the right driver for each one.

Anyone know a digital download installer for Windows 7 Ultimate that does
not need to be burned to a DVD?

Some of the other fixes for this I have read and tried and does not work

Change IDE mode for hard drives to AHCI mode,
Make sure the DVD Rom in the first boot device and its jumper is on master
Delete some filters for the DVD Rom in the existing Windows installation.
Make sure you download the lastedt SATA and Chipset drivers and have ready.

My motherboard is Gigabyte UD2

If anyone else has any additional ideas the would bee welcome. Right now I am
dead in the water.

Are you sure about that? Every user that I've ever seen with the error message has successfully installed using a USB key.

I am 110% sure. I have the memory key right here and I can boot off of it
and it starts the installer, then goes to the blue GUI and then I click
on Install Now and then I get the driver box.

Someone posted it could have been a bad download although when I burned
the ISO to the DVD the burning software did not report any CRC issues
or anything. I am in the process of re-downloading the ISO so who knows.

But to answer your question, yes I am positive about that.

Oh, I also (before I had attempted to boot from the memory key) switched
out the DVD Rom drive for a slightly older one and I got the same error message.
I really don't think its a CD/DVD Rom driver it is looking for but that is what it says.
If I remove the DVD-Rom totally out of the system why would it come up on
the install from the memory key and ask for a CD/DVD Rom driver? Makes no
freakin sense.

Windows 7 Ultimate RTM

Since you say you have the ISO file, why not just use Daemon Tools and mount the ISO file and run the setup from there. - Published Software Download

Good luck.

XP Pro/Vista Ultimate (64)/Windows 7 Ultimate Signature Edition(64)

Just wondering if it could perhaps be an IRQ conflict?
open the case and unplug any USB/Firewire header connectors, PCI devices (except your graphics card) secondary hard drives, secondary DVD drives if you have them.
Also try swapping your SATA cable with a spare if you have one, and plugging it into different SATA ports.

Yeah, can't do it.

It did not work trying it in Vista and now in Windows 7.

If I run setup from the DVD or from an ISO mounted drive, I get
an error about SPWIZENG.DLL not being able to be ran in Windows.
I researched this and it said that I needed to burn the ISO to
a DVD and boot from the DVD. The image does not support
running setup from Windows. Unless someome knows some
switches or anything else I can try.

It sounds like your PC has an allergy to Windows 7...

No system specs, so I have to ask: Do you have SATA? If so, make sure BIOS is set to SATA and try again.

If it still prompts for drivers, you need to unzip your SATA drivers onto stick and browse to them from the installer prompt.

Are you booting from the installer or running from an OS? Which OS?

Windows 7 Ultimate x64 SP1

Once you update your system specs, we can better assist. Click the link in my signature for instructions on how to edit your system specs.

Here's something to try - plug in your flash drive and reboot, but boot from the DVD. Also, you might want to download the ISO again and verify the checksum matches. If you downloaded with Firefox, use IE this time. Quite often this error is attributed to a bad download and burn.
