It is very frustrating to see that when a user is in the midst of doing something, the computer displays a message “Boot Device not Found”. What is even more frustrating is that there are not that many indications on how to proceed to fix the problem.
The message is displayed by all the computer manufacturers such as HP, Dell and Lenovo and each of them tries to suggest to use some function keys to diagnose what the problem is.
In my experience, unless the boot order has been accidentally changed in the Bios, that message means that the hard drive failed. Is that simple.
However, before reaching this conclusion, it is worth trying to troubleshoot the computer by doing the following:
– Turn off and on the computer again
– At the moment of turning on the computer again, press Esc and go to the boot menu; check if the boot menu order displays the hard drive of your computer as first in the boot order.
– In the Bios, check also if the hard drive appears in the list of the connected devices; if it doesn’t the hard drive is dead and needs to be replaced.
– If all of the above are unsuccessful, change again the boot order of your computer and pop in a Linux Mint 64 bit cd and see if you can recover your data with Linux.
– If even the Linux CD proves to be useless, it is time to remove the hard drive and plug it in onto another computer or to an adapter to get the data off of it.
– If the Linux CD reads the data, copy immediately the data to an external hard drive or to a flash drive
– If even the attempted data recovery fails through the adapter, it is time to contact professional data recovery companies who can extract the data you most care about.
Most of these steps which are time consuming could have been avoided if there was a backup in place. Pc Doctor Westchester recommends to perform two types of backups: a local backup to an external hard drive and a cloud backup. Among the two we prefer the offsite cloud backup because it is more resilient against malware and ransomware and if your machine is hit by ransomware your files reside in the cloud and can be restored back very quickly.
