When searching verifying the correct version for my BIOS update I ran into an insidious website that rather than providing me any type of info of a potential updat rather provided me with redirects, PUP's and all types of junk that was challenging to rid the computer of. After I found the correct version to update my BIOS I flashed the download and the BIOS is now updated correctly. I don't know exactly if the attack is still pestering my system or I may be dealing with something else Point being if this is in the wrong Forum category I apologize in advance. This is stats as to my Acer Aspire Es-711. The issue I'm having is that when I Configure the BIOS such that the computer will search for the Hard Drive (C:\) I get an obtrusive message stating that there is no bootable device found. This is using the UEIF and Hard drive configuration. I get this message directly after booting the machine in this configuration. This would lead one to think that there was an issue with the HDD and that one would follow that Rabbit hole (as I did ) for a resolution. What I learned in researching this is that when setting the BIOS to boot to the USB/CD/DVD The machine that happily takes me to a screen asking me to push the "any key" to load the Windows Program. My immediate thought when this first came up was it was absurd as the computer was not able to find the bootable device. To my surprise the machine not only loaded windows 7 Ultimate but I'm now currently typing this post using the computer in which it can't find the bootable device???? Things I've tried: I read in a Post that if one was to remove the HDD from the computer unplug from MB many times just this action would change things for the computer to find the HDD. .I did that and still no joy finding the missing bootable device. After installing Windows I was then able to run (using the Administrator CMD prompt) Chkdsk /f C:\ In which was completed successfully indicating that all sectors were scanned and accounted for without signs of errors. I would truly appreciate whatever assistance available. Regards.
