Boot Disk Failure can occur for several reasons.
Many problems are due to BIOS setting issues, faulty cabling or Hard drive
Check if your computer BIOS settings are correct.
If your hard drive is turned off in the BIOS, then the computer system
will fail to boot up and give you a boot disk failure error.
Check cabling from motherboard to hard drive.
Verify if the power supply to the hard drive is powered. Sometimes
reseating the hard drive connections will fix your computer failure.
Hard drive physical failure will result in a boot disk
failure error as well. In this case, your best option is to send
RestoreMyData your failed hard drive for evaluation. If your data
is not important, then all that is needed is to purchase a replacement
hard drive and re-install your operating system and system programs.
Logical hard drive failures can also result in a Boot
Disk Failure message when a partition is offline, corrupted or deleted. Many
computer users fail to recognize the exact cause of the Boot Disk Failure,
although many are easily solved.
