    Inspiron 15R SE 7520 Windows 8 Reinstallation


    Hello,

    I recently upgraded to Windows 10 from Windows 8.1. I attempted to reset my computer, so that I had a fresh install of Windows 10. Long story short, my computer ended up in an endless reboot sequence followed by the error: INACCESSABLE_BOOT_DEVICE. After hours of searching online and troubleshooting (I am not the most technologically savvy person, mind you) I gave up and decided to call Dell tech support. Dell tech support did some very basic troubleshooting, then gave me a re-installation disk of Windows 8 and kicked me to the curb with no further support (unless I paid a 'low' one-time free of $129.99 ). I now have the installation CD, but fixing my PC is not that simple. I am attempting to re-install Windows 8, but I have a number of partitions and for all of them I get the message "Windows cannot be installed to this disk. The selected disk is of the GPT partition style" or something similar. I have read a few other people on these forums with the same computer that have eluded to how much of a headache having an SSD and HDD in the same computer along with all of these partitions is. I don't know what to do next to get my computer to work. I appreciate any help I can get from the community. Thank you

    If my previous post isn't clear enough - I can't even get into my OS. When I try to use the reset/refresh utility it says my the hardrive my operating system is on is locked or the partition needed is missing. I am trying to reinstall windows using the setup utility and then clicking through to the custom segment. Then it pops up with various partitions and asks me where I want it installed. It won't let me install it on any partition. Do I need a specific driver or something? I have tried downloading drivers from Dell and putting them on a USB, but I can't figure out how to get them installed also. I am just shooting in the dark. Thank you

    once you get to the "partitions" screen
    click on and delete every partition..

    then point the installation to the unallocated disk space

    Hi KYHI, just to clarify the disc is a reinstallation disc of windows 8. Will it still be okay to delete the partitions and do what you instructed? Thank you for your help!

    Thank you so much for your help, I will do that tonight. Do you have any idea why it is saying my drives are all locked, etc...? Just curious.

    due to a pending operation.. be it a restore, startup repair or whatever..

    Use could also > while on the INSTALL screen
    press SHIFT + F10 and bring up a Command Prompt
    Type> Diskpart
    Type> Select disk 0
    Type> Clean

    Close command prompt and continue with installation

    This will also clear your HDD

    Hey KYHI, it worked, but I did windows 10 instead of 8. I am having a problem where many of my devices are not being recognized like Intel Rapid Storage Techology, etc.. Is this as simple as installing the drivers? My computer still have to boot in legacy mode under ACHI. Thanks

    For people configuring their PCs for the first time all by themselves, an error message like “Windows cannot be installed on this Disk” can be a big time problem. One, the message explains little about its cause and second, most of us don’t really have a lot of experience in setting up systems. The problem, however, is not as elephantine as it seems. It is simply a compatibility issue. This problem generally occurs when you try to install windows on a UEFI-based system while your hard drive partition scheme does not support UEFI.

    The agreement between the firmware and the hard disk partition scheme is essential for locating the boot loader for the Operating System and hence, is the first step in the installation process of windows on a computer system. By default, recent hardware boot using UEFI mode. Thus, when one tries to use an old hard disk with an updated UEFI-based system, the message “Windows Cannot be Installed On this device” pops up. This is because old hard drives maintain partitions using MBR scheme which is not supported in UEFI-based systems. Therefore, for windows installation it is important to convert either MBR partition scheme to GPT partition scheme or configure the system to boot with the legacy BIOS-compatibility mode.

    You can use a freeware AOMEI Partition Assistant to convert disk between MBR and GPT without data loss.
