First BSOD, then boot failure.

Hi.
Some days ago my computer got a BSOD (driver_power_state_failure), and when I started up again I get this screen:




****************
Recovery

Your PC needs to be repaired

A required device isn't connected or can't be accessed.

Error code: 0xc000000f

You'll need to use the recovery tools on your installation media. If you don't have any installation media (like a disc or USB device), contact your system administrator or PC manufacturer.


Press Enter to try again
Press F8 for Startup Settings

****************





and if I press ENTER or F8, it just refreshes the screen. But the first time I press one of them, I get a slightly different screen;






****************
Recovery

Your PC needs to be repaired

The application or operating system couldn't be loaded because a required file is missing or contains errors.

File: \Windows\system32\winload.exe
Error code: 0xc0000001

You'll need to use the recovery tools on your installation media. If you don't have any installation media (like a disc or USB device), contact your system administrator or PC manufacturer.


Press Enter to try again
Press F8 for Startup Settings

then I tried doing what it said (recovery tools on installation media), but that didn't work. But something it did do, was to change the language of the screen. Originally, it was in Norwegian (my system language), but after the "repair", it changed to English.

The details of the "repair" said (translated from Norwegian, as the installation media is in Norwegian):


****
Originally cause found:
-------------
System volume on disk is corrupt.


Repair Action: Repair the file system (chkdsk)
Result: Complete. Error code = 0x0
Time spent = 593 ms
****

Opening the D:\ drive (OS drive) from an external OS doesn't work, it's there, but it's like it just ignores it. It also states that the disk size is 0 bytes.

I know that a clean install of Windows MIGHT work, but I'd rather not lose everything I have on it.
Please answer quickly if you can.

This may work..
