First of all i wanted to greet everyone here, as this is my first post on this forum 🙂
Now to the problem.
I am happy owner of HP Pavilion dv7-1150ew laptop. It's a good computer, i really like it, but the OS it came with (Vista Home Premium) was temporary from the beginning. I knew from day one i'll install Windows 7 as soon as it becomes available. And the day came. Windows 7 Professional appeared on the MSDNAA site. I downloaded 64-bit version, burned the DVD disc and waited for the weekend to come to do the installation and post-intallation stuff.
So, am i Windows 7 user now? No. I am not. I didn't even get to the installation process 😞 The installer boots up flawlessly, i choose language, then i click Install now, wait and... "Missing required CD/DVD drive device driver" message appears. Here's what i tried:
- installing from USB pendrive (formatted the pendrive to NTFS using diskpart, unpacked the iso to pendrive using ultraiso and winrar)
- providing Intel ICH9M/E-M AHCI SATA driver version 8.9 to the installer - it shows the progress bar for a while, then the "No new devices could be found" message appears
- installing 32 bit version
- installing from USB pendrive with DVD drive and secondary harddrive disconnected
- installing to clean harddrive (i dropped both system and recovery partitions)
- updating laptop BIOS
- updating DVD drive firmware
Still the same problem. No required driver, and if i load the Intel SATA driver - no new devices.
The Windows 7 Professional from MSDNAA is at least RTM release, as it has no RC, Beta or whatever next to it.
I googled that others who had this problem solved it by switching SATA controllers from AHCI to IDE mode (or otherwise), but BIOS on the DV7 laptop doesn't have any regarding option.
Just googled that error, and found many threads about it in the TechNet forums. I suggest you search there for better results, and post the steps that worked for you in here. Just linking you to a thread below that could be helpful.
Thank you for your reply. I didn't find these threads earlier, thouhg i googled for error 🙂 I read through these threads and got some new ideas. First was downloading ITA 8212 ATA driver and providing it to the Win7 installer - it didn't help (does dv7-1150ew even has this chip?). Second idea was to install Vista 64 and starting Win7 installation process in it. I downloaded Vista 64 Ultimate from MSDNAA, unpacked it to the USB pendrive and installed without a glitch. Then i installed Intel chipset drivers and Intel WiFi chip driver (so i could connect to the net and check for further drivers updates on windows update - it had none). At this point i decided to try with the Win7. It didn't work 😞 Now i get the SPWIZENG.DLL/autorun.dll error right after trying to launch the setup.exe. Think i'll try to redownload the Win7 ISO.
I asked a friend of mine to burn the ISO he has downloaded for me and it installed without any problems. What's worth noticing is the progress bar/splash screen when installer loads up. My version was showing the vista-like progress bar at the bottom of the screen and my friend's version shows Windows logo in the center of the screen. Both are Windows 7 Professional 64-bit English and both are downloaded from MSDNAA, but mine was downloaded few days ago and his 15th august or so (just when it got released). Maybe something happened and the ISO at MS servers got corrupted?
Anyway everything is allright now, thank you very much for your support 🙂
