Here is a weird one,

Got computer with Windows XP. It's getting stuck on a black screen with cursor blinking.

What did I do: - Boot from installation CD (recovery option - command line):

  chkdsk C: /R
  copy D:\i386\ c:\
  copy D:\i386\ntldr c:\

Chkdsk showed 0 bad sectors and no problems during scan. dir on C:\ shows all directories and files in place (Windows, Program Files, Documents and Settings). BIOS shows correct boot drive.

Still does not boot. Not sure what to think of.

Please help.

Could you clarify what you mean by "cursor blinking"? If it literally is appearing and disappearing repeatedly, that sounds very bad. – Dr Kitty Jun 19 '12 at 0:45

"stuck on a black screen" - What preceded this black screen? Was it the VGA "Windows XP" w/black background or the "welcome" w/blue background? – sawdust Jun 19 '12 at 0:55
Black screen was preceded by a SONY VAIO logo, which means right after BIOS screen. – Radio Jun 19 '12 at 0:59

Got it finally fixed, here are steps:

  • Backup "Windows, Program Files, Documents and Settings" folders using True Image.
  • Start new Windows installation with deleting all partitions and creating new ones.
  • After first reboot during installation, boot from any Live CD and delete newly created folders by setup ("Windows, Program Files, Documents and Settings"), leave other files in place (don't delete them).
  • Restore original folders from True Image.

That's it.

Is there a USB drive attached? Disconnect any HD or USB storage devices if so.

Good guess, but USB devices are not connected and BIOS option for External Devices Boot is turned OFF. – Radio Jun 19 '12 at 0:25
I'm sure you've already checked this, but is the right hard drive set as the first bootable drive? – Robotnik Jun 19 '12 at 2:06
Yep, even tried to disconnect DVD-ROM... – Radio Jun 19 '12 at 2:11
