This is the error message that my computer had:


Your PC/Device needs to be repaired

The Boot Configuration Data for your PC is missing or contains errors


Error code: 0xc0000185

You'll need to use recovery tools. If you dont have any installation media (like a disc or USB device), contact your PC administrator or PC/Device manufacturer.

Press Esc for UEFI Firmware Settings"

I made a recovery drive and set the UEFI to a USB boot, and when I tried to boot it with a blank USB it didnt recognize it, but when I used the recovery usb it recognized it. I did that to check and see if it actually recognized the recovery data.

Now when I boot it just has the Lenovo screen and the swirling dots. it's been doing this for about a half hour. Is this normal or is there an issued with the hatdware?

The Error code: 0xc0000185 is an I/O error.

This can be a hardware problem or a software problem.

So the first thing to do is to run diagnostics on the hard drive ( http://www.carrona.org/hddiag.html )

If you have difficulties booting to the disk/drive, post back and we'll see about changing some settings in the UEFI to allow the boot.

I'm working on a drive that will do this for you, but it's still in the testing phase (and it's a 700+ mB download).


If the drive is dead/dying, you may have problems trying to recover your data.
Do you have a recent backup?  If not, post back for suggestions on how to best backup your information.


FYI - if it is dying, then it's best not to use the drive at all until you've done the backup.

If the drive does die fully, then data recovery gets very expensive (up to $2000 (US)) if it's even possible.

My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.
