Can a virus make the hard drive undetectable in the bios? If so, how would I go about scanning the computer for a virus at bootup?

Also, this is in a laptop. What happened was a friend of mine left her computer connected to the internet overnight and the following day she booted up, got the windows screen then the screen reverted to black with it repeating something about dhcp... over and over. Also, her virus software had expired. I don't believe it is a loose cable in the laptop though.

it's not common but it is possible. Try updating the bios for the mainboard first off. If that does not work it's likely a bad cable, jumper on the back of the hd, or the hd crashed. Make sure everything is connected properly and in place though. You could also see if the hd works on another computer. hardware switching narrows the problem down.
Good Luck Bro!

I am not sure if a virus can make the hard drive undetectable or not...
Have you tried pulling the battery off of the motherboard , wait 10 min. and put the battery back in and then go into the bios and set it to "Auto Detect" the hard drive ?
If the bios still cannot see the hard drive, check to make sure the cable is plugged in snug or replace the ribbon cable. Make sure the power lead to the hard drive is plugged in tight.
Still no detection ? Time for a new hard drive...

Perk2U had a good answer, but instead of removing and reinstalling the battery. If it is 2 or more years old, simply replace it. Whether or not that fixes it, problay needs battery any way. rest of her answer is great.. Bios batteries should be replaced every couple of years regardless. Also, if virus got the boot sector, can be repaired by deep format and reinstall of programs. Good luck

Any good virus that's made, the 1st difficulty that it will do is locate your anti virus application and uninstall it.. And after it uninstalls it, it won't permit you reinstall it the two, by making use of blocking off it. administration Alt Delete, form by making use of memory utilization. and cancel the main important difficulty on there.. The report wont stay massive, it is going to selection.. Its slows down your laptop by making use of establishing some thing very massive each and every, say each and every 5 secs. in case you click on the overall performance and the project sounds like your grandpas coronary heart video reveal, to procure an epidemic. ought to stay approximately even. when you close up out this methodology you ought to have the skill to boot the anti virus, till it self opens back.. Wait, are you even attending to residing house windows?... Your speaking approximately BIOS. so im guessing your not. in the journey that your not attending to residing house windows its not annoying to get there regardless of an epidemic. bypass into you project-loose enter output settings (BIOS) and set it so as that it seems that on your residing house windows in the CD-ROM and positioned your unique residing house windows disc in there. which will provide help to get to window.. you do not % your annoying stress to open that.. there is 3 styles of anti virus application that works, Norton and McAfee (the two quickly to bypass out of company) and residing house windows stay, something is purely BS do not pay funds for something, and residing house windows stay would be loose quickly..

not usually, this is mostly caused by a loose cable, wrong master/slave setting, having an IDE cable attached to a hard drive and a cd/dvd drive. It can also be caused by a bad hard drive, or a PSU with out enought power.

you cant. its shot. but check the cable and power connections to make sure theyre not loose. the boot sector is a virus favorite lunch. i truly think castration is not enough punishment for the vermin that do this and i hope when same are caught they are used for public example.

it can be done... but only with a boot loader.
the boot loader hides the drive after all the bios post messages and checks are through and the loader loads itself.
windows vista does this...it requires a low-level format just to uninstall it.
