Vista - Windows Vista Dead (0xc0000e9)

First, Office Word crashed several times (while I wanted to edit an equaion
in a table, that changes it's size with the content) until it was unable to
save anything. I've then restarted my computer, than try it again. Same
affect, but it sudenly started to slow down radically. I had egnough of this
silly thing, and forced my computer, to turned of. I've restarted in windows,
and it's not booted, it's stopped after the green statusbar. I've tried to
fix it, but it said that cannot start 'couse of a removable device, I/O
error. I heavent added any new device, and removed the USB drive after this,
but not helped.
Since I can boot in to Linux wich is on the same hardrive, I doubt that the
contact has been gone from my hardrive, and my computer. I bet that the
filesystem is demaged. I heaven't tried out all my ideas, but I'm desperate
about this, couse I'm goin' to need Windows in the future. The next step I'm
going to do, is run ChekDisk form the install disk repear feature, tomorrow.
(If it's not crash.) I will send weather it was sucseed.

Have any idea what happened? When is the 0xc00000e9 occur? How to fix it?

P.S.: Just in case: I'm using the computer with a linux, and it has onyl one
harddrive, and it's a laptop, so i'm not gonna replace any hardware in it.

I have fixed it! 2 days before, I run ChekDisk trough the Installation Disk
Repear feature. On next day, I run StartUp Repear, and it made the trick.
Well not exactly...
Now some of the drivers, and system files is missing. Yet I didn't checked
the damage. All the applications is crashing, but I can fix that.

But I still don't know, and want to know the following:
Have any idea what happened? When is the 0xc00000e9 occur? How to fix it?

`... but I can fix that.'
But it seems that I can't. Some of the Windows main features, as skins or
network managging, have demagged. (Before chrasing, I had 9 GB free, and
after chrasing I have 16GB free) I have installed previously the PowerShell.
I want to repear my operating system, by install it as an update, but it
keeps telling me, to uninstall. I thought I did, and it seems that some of
the registry entry still exists, that is have to do something to PowerShell.
Mainly I don't care that if it's installed, or not.
How can I tell to Vista installer to ignore compatibility, and force it to
install, or just repear (In hungarian!!!)

PLEASE, Help!!

Of course I dod not wanted the answer in hungarina, but the installation.
It seems, that I had removed (ruined) PowerShell egnough, so I could started
the installation. But the installation stopped, 'couse it could not find some
of the resource. I only want to repear windows. How can I do it? If the
Service Pack 1 final will be released, and upgrade my installer with the help
of vLight (vista variant of nLigth), it will be updated?

by the way, when it will be released?

-- I hope you gus not ignoring me, or removed the thread 'couse I have
mentioned about adoring the idea of using linux or simply the word?
