Careful diagnosis holds the key to fix the start up woes effectively. You should look for following symptoms to ascertain start up problems. However, average users are unable to find a way in such situations. The trained professionals of Ask PC Experts can come to immediate assistance and do the needed steps. Not only they are used to experiencing such challenges but are also available 24*7 to handle and resolve all start up problems. Some of the main symptoms behind startup evils are:

• "NTLDR is missing"
• "Error loading operating system"
• "Windows could not start because the following file is missing or corrupt"
• "Invalid Partition Table"
• "Missing Operating System"
• "A disk read error occurred"
• System hangs after BIOS POST finishes
• "Windows could not start because of a computer disk hardware configuration problem"
• "Could not read from selected boot disk"
• "Check boot path and disk hardware"

The probable causes of these errors vary from corrupt master boot record, hard disk, virus infection, corrupt boot sector and corrupt or missing Boot.ini file to corrupt Boot volume.

Apart from these error messages, a number of other Windows startup problems can take place including:

Blue screens. Also known as stop error, Blue Screen of Doom and BSOD, Blue Screen of Death is generated by the operating system, most notably Microsoft Windows, when it has suddenly terminated with an error. It leaves the system locked up with a diagnostic information display image of white text on a blue background.

The blue screen may include some hexadecimal values from 00 to 11 (0 to 17 decimal) which can be used to ascertain the causes of the error.

Dialog box saying "One or more services failed to start". Misconfiguration or registry corruption may be behind this error but it can also be caused by application incompatibility of some form.

Hung system. Erring drivers or corrupt system registry by registry corruption and virus infection can also cause the Windows start up to fail.
