Windows 7 boot failure, boot manager not found?

I have a Sony Vaio VGN-SR26GN with Windows 7 32 bit installed.

It froze, ctrl+alt+del did not work so I turned it off and on but it could not start windows, all I ended up with is a black screen with movable cursor, same with safe mode.

I tried recovery, last known good confirguration, etc... but nothing worked

Then I started getting the blue screen of death with the BOOT MANAGER NOT FOUND or something of that sort

I tried using the windows 7 repair CD but it failed to detect any windows installations or any other partitions... Tried the different bootrec commands but nothing worked

Now when I turn on the computer it starts the Vaio repair utility, opens a blank blue screen and nothing happens for hours.

I am not sure if this is a hardware or software problem. What else can I try to do?

Thank you

References to Vista also apply to Windows 7.

This is serious error and "may" not be repairable without professional tech support from
a real computer shop (not leeks and peeks at a BestBuy or other BigBox Stores) or your
System maker's Support.

If you do not have a Windows 7 disk you can borrow a friends as they are not copy
protected. Your System maker will also sell the physical DVD cheap since you already
own Windows. Also you can make a repair disk on another computer.
