Harware tests out OK.

Answer 2

Hi there,

The IO1_INITIALIZATION_FAILED error is about the I/O system failing for some reasons. More likely that this will happen if the system is configured differently, improper shutting down of the unit, or a different configured update.

Press F8 while booting your computer to access System Recovery options.
Click Troubleshoot.
Select Command Prompt.
Enter the following commands below, then press Enter after each command:
chkdsk c: /f
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
bcdboot c:\windows /s c:

Once done with the above commands, restart your computer and see if the problem is fixed.

Answer 3

I tried each of those with no luck. Ultimately, I reinstalled Windows and so far, so good.

We did experience an abrupt shutdown of the unit due to a power outage and failed APC unit prior to the problem and I assume that the events might be related.

Thanks!
