I have posted separately so that you cannot miss it.
The slight problem we have, as I am sure you have realised is that this is so new, that none of us have really had time to build any real degree of knowledge in respect of the particular OEM computers and the actual presentation of the UEFI User interface screens
Here is an example- it is not yours it is Asus but it will give you the idea of what I said in my last
Windows UEFI boot sequence detail
Assuming you have installed Windows 7 X64 on a GPT disk, the following boot sequence happens:
- The UEFI firmware of the Asus motherboard will first initialize the hardware
- The UEFI boot manager will now load the boot application as pointed by the Boot Option Priorities. In case of Windows on GPT disk this should be the Window Boot Manager entry.
- The Windows boot manager presents the user with a screen where he/she can select the instance to use and loads the Windows OS loader selected. Note that if there is only one instance of Windows the Windows Boot Manager calls directly the Windows OS Loader without user interaction.
- The Windows OS loader loads Windows and gives control to the Kernel
and it will without doubt be the same principle on your computer provided it was pre installed windows 8.
as UEFI does not use MBR partitioning but GPT
Additionally to that unless it is an amazing coicnidence you have also asked for advice on the same problem elsewhere
I am not suggesting for one moment of time, that there is anything wrong in that, but I would echo the advice issued in that other place as well as what I have said
You need to see if you have options for repair your computer on the advanced boot options where you accessed safe mode and then on those options select cmd prompt
you will be in a ram drive with a prompt X:\Sources>
you then need to try a chkdsk on the drive that has windows installed
if at the X prompt you type
C:
and key enter
then
dir
and key enter
If windows is not there try
D:
when you find windows type
go back to that prompt for that drive and type
chkdsk /f

That all said if it is only a few weeks old, refer it to the supplier
