Cannot install Windows 8 on 7720 (Inspiron 17R (SE))

This question is answered

Windows 8 will not install on the Inspiron 17R SE 7720.

Yet it is listed as being supported here:

http://supportapj.dell.com/support/topics/global.aspx/support/kcs/document?docid=575111

I have gone through the step for a clean installation here:

http://supportapj.dell.com/support/topics/global.aspx/support/kcs/document?docid=575110

Then when it comes to point 7, it only lists one hard drive. Shouldn't there be 2 listed? Anyway the hard drive that is listed is named as 'Drive 0 Partition 1' with a total size of 931.5GB. Then when I delete the partition and select the unallocated space it says

"We couldn't create a new partition or locate an existing one. For more information see the setup log files.'

My only option then is to quit setup, and I don't even know where the log files are found.

I have also installed the latest bios located here ( http://www.dell.com/support/drivers/au/en/audhs1/DriverDetails/Product/inspiron-17r-se-7720?driverId=76N71&osCode=BIOSA&fileId=3080131888 )

How can I get Windows 8 installed on this?

  • Hi,

    The Inspiron 7720/17R (SE) is shipped with mSATA drives with capacity of 32 GB. If you are referring to this hard drive as the one not visible in the list, that is as per the design. The mSATA hard drives are mainly used for caching purposes and to enhance the system performance. In order to re-install the Windows with an mSATA drive present in the system you will have to disable the Accelerate form iRST application.

    • Launch Intel RST User Interface from system tray.

    • Select “Accelerate” Tab, click “Disable acceleration”.

    • Click “Reset to available” to reset volume.

    If you have formatted the OS partition already, you will have to install the Windows in AHCI mode. And follow the steps mentioned below.

    • Boot into OS in AHCI mode

    • Once the Windows Desktop Appears

    • Click Start, type Regedit

    • Right click Regedit and run as administrator

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorV

    Change REG DWORD Values of Start from (3) to (0)

    • Close Regedit

    • Restart

    • F2 – Go into bios

    • Change sata mode from  AHCI to Intel smart Response Technology

    • Save and exit

    • After system reboots, download and install the iRST application and Enable the acceleration.

    I hope this helps, please do write back in case you need any further assistance.

  • Thanks greatly for your response, swapnajan.

    The hard drive I am referring to as missing is the second 1.0TB hard drive. I thought it would list two in the setup. I have the top of the range 17R Special Edition Laptop with 2 1 tb hard drives and 3D capability.

    Anyway I tried install again by removing the second hard drive and the message I got then was 'We couldn't find any drives'. That was a puzzle as I still had the C drive in my computer and Windows 7 was running from it.

    So I have now placed the second hard drive back in again.

    I haven't formatted the OS partition yet as it wouldn't let me. saying it couldn't find any.

    You mention AHCI. Will I be able to install windows 8 from boot if I change the bios setting from Intel Smart Response Technology to AHCI? Then once Windows 8 is installed switch it back to Intel Smart Response Technology?

  • I have done a search trying to find others with a similar problem and it seems that it has occurred in this topic as well en.community.dell.com/.../19471140.aspx

  • Actually, its all good now. I just disabled the acceleration as you suggested first and it seems to in installing now with no problems. I thought that was only within windows and didnt matter if you tried installing from boot. Thanks so much, though. Very easy tip! You should have it up on the dell site somewhere as I'm sure I'm not the only one.

  • Hmm.. now that I've installed Windows 8, I can't seem to install the Intel Rapid Start Technology driver here:

    www.dell.com/.../inspiron-17r-se-7720

    After running the download it says 'This computer does not meet the minimum requirements for installing the software.'

    How can I enable that again?

    Also, the second hard drive I have isn't visible within Windows anymore. Yet it is listed in the bios. How can that be fixed?

  • Ok, finally got my second hard drive back by using disk management and was able to enable intel rapid start again by following this en.community.dell.com/.../dell-whitepaper-intel-responsiveness-technologies-setup-guide.aspx

    Problem is now when I go into Intel Rapid Storage technology and enable that it stops the intel rapid start from working as it overwrites the data that was created for that on the msata. How can I have both like I did in windows 7?

  • All solved! Finally! You need to enable intel rapid storage before you do the setup for intel rapid start. I was doing it the other way around. All fixed now.

  • Where do I have to enable the IRST? In BIOS?

    So the tutorial posted above is correct? I'm a bit scared because I read a lot about blue screens when disabling ISRT (http://support.euro.dell.com/support/topics/global.aspx/support/kcs/document?docid=575109#Intel-Rapid-Start, at the bottom of the page)

    I think I have the same problem: en.community.dell.com/.../19473153.aspx

  • Duy, I always left irst enabled in the bios. I never switched to ahci or ide.

    I can only say what I did. First it was this step from within windows 7:

    • Launch Intel RST User Interface from system tray.

    • Select “Accelerate” Tab, click “Disable acceleration”.

    • Click “Reset to available” to reset volume.

    Then I was able to do a clean install by booting to the windows 8 dvd, and deleted all partitions.

    Once windows 8 is installed, you need to install the intel rapid storage technology driver, and then enable the acceleration. It's in this guide: en.community.dell.com/.../Intel-Responsiveness-technologies-0.91.pdf

    It tells you about how to enable the intel rapid storage tecnnology first and then how to do intel rapid start after. For a while I was skipping over the intel rapid storage instructions, thinking it didn't apply to me, and I only had to do the rapid start setup, and then I could enable acceleration afterwards but it doesn't work like that. The acceleration with the rapid storage needs to be enabled before the rapid start is setup.

  •  this worked for me. When you want to install windows 8, you have to leave the bios sata mode in INTEL SMART RESPONSE TECHNOLOGY.  Then boot off windows 8 cd or thumb drive. the problem now is that you cannot see the hard drives but follow these directions then it will work.  
    Lets try this. Our goal is to de- accelerate the SSD and the HDD which could be causing the no boot. So our primary target is to get to the CMD whether its windows 7 or windows 8 . For windows 8, initiate a boot failure so we can enter the advanced boot options or if boot is good, enter the elevated CMD inside the OS.
     

    .          Boot from windows 8 cd or thumbdrive and instead of choosing install, choose repair and get to a command prompt through advanced options

    ·         Type > Diskpart

    ·         Type > List Disk

    ·         Type > select Disk 0

    ·         Type > Clean

    ·         Type > List Disk

    ·         Type > select Disk 1

    ·         Type > Clean

    ·         Type > Exit

    ·         Click Restart

    then boot off of your windows 8 cd or thumbdrive and now you will see both drivers, then install windows 8 on your sata disk, after install go to dell website and install Rapid Storage Technology driver and then reboot and run the RST and enable hardware acceleration.  Works like a charm!!!!

         

  • Thanks ComputerNY, these instructions worked perfect for clearing the metadata.  One note, the BIOS must be in AHCI before Diskpart can be used.  Then after the disks are cleaned, switch back to ISRT.

  • yeah no problem.  Im glad i can help.  I managed to use windows 8 for quite some time.  The ISRT worked fine, my 14z ultrabook booted within about 15-20secs.   I eventually had to downgrade back down to windows 7.  Even after all of the frustration trying to figure out ISRT with windows 8,  I went back down to Windows 7.  The problem I was facing with Windows 8 and our 14z ultrabook was i kept getting an audio buzz/video buzz intermittently.  Even though I updated the latest windows 8 drivers for both audio and video and chipset drivers.  I still had an annoying buzzlike skipping sound whenever i played either audio or video.  Again I called dell and they were no help.  Tried a good program called slimdrivers that automatically installs latest drivers and still for some reason I had that annoying buzzing sound every 2-3 mins.  At that point I just pretty much blamed it on windows 8 being so new and drivers maybe not that compatible.  I downgraged back to win 7 and everything is flawless.  No buzzing, ISRT works like a wonder.  So anyone else out there with a 14z ultrabook experience that audio issue??  So far Im just gonna stick with Windows 7.  I have no problems with it.  Windows 8 was cool looking but i will wait until bugs are fixed.  

  • This may help some people who are doing a bare metal installation of Windows 8 on an Inspiron 14z.

    Firstly I made sure that iRST was switched on in BIOS. I then booted from the Windows 8 DVD and very soon got the message:

    Load Driver

    A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.

    Note: If the Windows installation media is in the CD/DVD drive, you can safely remove it for this step.

    I downloaded the Intel Rapid Storage Technology Driver from the Dell support site (AHCI_Intel_W8_X00_A00_Setup-W1DW3_ZPE.exe at the time of writing), unzipped it using 7-Zip, popped the extracted files onto a USB stick and loaded them in at this point. Everything went smooth from then on and Windows installed just fine. I then ran Windows Update to get the latest drivers, etc.

    My next step will be to install the iRST application so that I can configure the mSATA drive. I'll then move on to the Rapid Start drivers/apps.

    Hope that helps.

    Andy.

  • I use Inspiron 14z, installed win 7. Now, I'd like to upgrade to win 8, still use SSD as cache.

    I followed these steps:

    1) In BIOS, switch SATA mode from ISRT to AHCI

    2) Install win 8 in HDD

    3) Install Intel Smart Response Technology

    But it displays:

    Some warning, exclamation mark says SSD is in incompatible??? So why?

  • Hi everyone!

    I have just got a Dell Inspiron 14z, which had Windows 7 on it. I tried to install Windows 8 on it, but I couldn't make it possible, because I didn't see the hard drive during the install. I loaded the appropriate drivers from a USB stick, and I could manage to install Windows 8, but it was crap.

    Next time I tried to install Windows 8 in AHCI mode, it was successful, but I couldn't get the SSD to work in ISRT.

    The other problem is that Windows 8 and HD Graphics 4000 are not very good together, and the laptop do not give any picture after the boot, except I put the machine in sleep mode and then turn it on.

    Can anybody help me?
