Vista - A major boot problem

I have an Acer Aspire 5315 laptop running Vista Basic and 2 days some files were updated,it then rebooted.then a box opened saying there was a start up problem and it tried repairing,it didn't work.i tried the system restore,factory restore thing,no joy. I then DL'ed vista recovery disc and used the command prompt and followed some on screen instructions on rebuilding the bcd,as far as i'm aware i did everything it said and it said all went successfully.When i rebooted it came up with this

file: ntoskrnl.exe
status: 0xc0000098
info:windows failed to load because a required file is missig,or corrupt.


also i get a notification comes up saying cannot find file:C\D2D\images\*.wsi when try to determine UI language

i then click restore to factory settings and i get this message restore failed - reason 0xa0000001 click ok to restart computer

i then go through the whole process and get the same answer.

Am i totally screwed or do i have other options to get it fixed,BTW in can boot into Ubuntu so i can still use the laptop but can't access all the files.

thanks Steve

You need to do a repair install.

Windows Vista Failed to Start with ntkrnlpa.exe or ntoskrnl.exe 0xc0000428 Error Status » Tip and Trick

hi, I have the same problem re "ntoskrnl.exe" i followed your advice to Steve and checked out the link, problem "our machine (Acer) had the VISTA already installed and we did not make back up discs, is there any other fixes?

This problem initially started when the computer tried to download 3 updates then tried to restart and as unable to the start up repair kicked in but it constantly does back to trying to update but fails!.
