    After I read everything on the subject of dual boot Windows and application of the same, I was unable to install windows 7 on preinstalled Windows 8.1, and ask for help from the community.
    Laptop Alienware 17x with 80 GB SSD mSATA drive, 1TB disk where the OS was and who was moved with a program Paragon to the new purchased 250 GB SSD.
    So, now is the OS on the 250 GB disk, all data on 1TB, a 80GB SSD is empty. On 1TB are still Recovery and OEM Partition. The 1TB and 250 are GPT / NTFS. WIndows 7 I try to install on 80GB HDD mode GPT / UEFI, MBR / Legacy, FAT32 / NTFS, but nothing passes. It appears the error 0X80300024. I tried to remove the 250GB drive, but the error is the same.
    Does anyone have any idea?

    Tnx RCB,

    I tried take out 250 GB disk and remain only with empty mSATA 80GB drive (which can not take out) and 1TB disk with data and hidden OEM partitions.
    I also have two sets of installation UEFI / GPT and Legacy / MBR.
    On both the same error.

    If I remember correctly, Dell's W7 (pre W8) didn't come with a system partition (which is needed for dual boot).

    Usually it is called a System Reserved (MBR partition) and is min. 100MBs.

    There is also some problems with that partition being to small and needing to be 200-400MBs for dual boot.

    I don't want to run you around because I can't say absolutely. I'm just hoping maybe I could give you some pointers to help search out the problem.

    Let us know when you get a little more info and we'll see where to look next.
