The strangest thing is the partition 4 message. Not knowing what has been done to the OS, software loads, set up etc, it is really difficult to say what might have created this/these issues. Since you are unable to get to safe mode, f-8 on boot prior to splash screen this might be a toughie without the OS disk(s) or a boot disk. If there is someone where you are with an available system you could look into creating a Win 7 boot disk, preferably using a flash drive, there are a couple of ways to do this including using Linux, a little tricky but doable, just google "Creating Win 7 boot disk with linux" and that should get you there. The very first thing to try (and not that this will alleviate your issue) when dealing with L/T issues, is a basic reset and you may have already tried this, shut laptop off, pull battery out, wait a minute, reinstall battery and restart. This is a basic ram reset than many do as a starting point in case an issue might be memory related, I doubt this will help but I generally do this as a preliminary procedure. I am sure that others will have ideas and may have possibly seen similar issues that might be germane to your Asus and I await commentaries from knowledgeable techs such as Bob Proffit or Kees Baker, they may well have seen this particular problem.
I have an ASUS R500V laptop running Windows 7 64bit.
When I hit the power button to boot up, a command prompt is displayed, reading "Disk 0 is now the selected disk. Partition 4 is now the selected partition."
Following this, I am prompted for Recovery and after that the error screen is displayed.
I am overseas, and do not have a recovery CD. I do have a backup file on and external harddrive.
