afeder, please can you post some more info... run a command prompt (cmd.exe) as an administrator and enter diskpart, list disk as shown below... (I just want to see if it's a GPT disk):
Code:
Microsoft Windows [Version 6.2.8400]
(c) 2012 Microsoft Corporation. All rights reserved.
C:\Windows\system32>diskpart
Microsoft DiskPart version 6.2.8400
Copyright (C) 1999-2012 Microsoft Corporation.
On computer: XPS
DISKPART> list disk
Disk ### Status Size Free Dyn Gpt
-------- ------------- ------- ------- --- ---
Disk 0 Online 698 GB 30 GB
DISKPART> exit
Leaving DiskPart...
C:\Windows\system32>
If it's GPT you might prefer to make a partition and install direct (not with Wubi) to the partition. Wubi is intended to install without partitioning (and it won't make good use even if you create a separate partition for it as it uses a virtual partition that is a single file). (And it's usually simpler partitioning with GPT since it doesn't have the same limits as MBR partition tables)
While you're in that command prompt, maybe you can output the result of "bcdedit" as well e.g.
Code:
C:\Windows\system32>bcdedit
