I just had a Lenovo 3000 N200 with Windows Vista that would not “boot” it just showed a black screen with the error code: 0XC0190036 !! 1234/72265 (Random.file) flashing onscreen
What I could read online was that the random.file (in my case xcopy.exe) was corrupted and therefore Vista would not continue… The fix is to delete the file and on a Lenovo that can be done from Rescue and Recovery preboot area, by opening the Opera browser and choose “save as” on a random link then browsing to the file thats corrupted (c:\windows\system32\xcopy.exe) right click on it and select DELETE, then cancel the save.
Now just reboot and SP1 should replace the missing file!
