How to Fix Disk Boot Failure
Level of difficulty:
Disk Boot Failure is a problem which arises when you try to boot the computer from the files installed on a disk which could be hard disk"
- A large number of disks to boot the system
- piece of cloth
- screw driver to open the cabinet
floppy or CD-ROM. Disk Boot Failure could arise from a large number of sources. Few of the reasons are corrupt bootable disk
order of devices to boot from in BIOS setting
problem with IDE port of motherboard and many more. The problem could be solved in more than one way. It really depends on which way works for you at this point of time.",Step 1 is to check your disk for any problem. Check if the disk is properly inserted and is working fine i.e. it is not corrupt and all the data could be read by the disk reader easily. Physically check all cabling connections in the computer system. A loose or in some cases
failing cable will produce these errors. Check if disk is not having any scratches and dust on it. If dust is there remove it and reinsert the disk and restart the system. If problem still persists move to step 2."
Check for your BIOS setting. Check for the order of devices to boot from. Because it might be possible that your settings allow your computer to boot only from the local hard disk and if that disk is not working properly your computer throws the error message as it is not having anything to boot from. For this go to the BIOS settings by pressing 'Del' key during booting your computer. Then go to Bios settings and select the order of the disks in which you want to boot from. Then save the changes and exit the system and restart. If the problem is still unresolved move to step 3.
A weak SMP could also be a reason. Check your battery for power supply. If it was the reason for the problem change the SMP as the problem would arise again if you continue with the same SMP.
Check your BIOS battery. It is the circular battery placed on the motherboard. Check if it is working fine. A dead Bios Battery will also cause the same problem. So remove it, clean it with a piece of cloth and reinsert it. Restart the system. If problem still exists move to next step.
Remove your RAM from the motherboard and clean it with a piece of cloth and reinsert it properly onto the motherboard. Restart the system. And if this also does not solve your problem call customer care persons of your computer's vendors as it might be a technical problem requiring professionals to handle it.
