Hello! Not sure if im posting in the right place sorry if im not! I have an asus g73j that is booting to a black screen with a blinking underscore in the top left. It was recently upgraded to windows 10. It became unstable then did this. I am able to get it into the flash utility but im not sure what to do from there. Any help would be sincerely appreciated!

Here's some repair/recovery/restore options (in this order):

This presumes that you can access Startup Repair.

1 - Startup Repair.  Run it 3 times, rebooting in between tries.

2 - System Restore to a point before this started happening.

3 - DISM/SFC repair (DISM doesn't work with W7, although SFC does)
    

Then please run the following DISM commands to see if there's any problems with the system (from an elevated (Run as administrator) Command Prompt).  Press Enter after each one:
   
Dism /Online /Cleanup-Image /ScanHealth
   
Dism /Online /Cleanup-Image /CheckHealth
   
Dism /Online /Cleanup-Image /RestoreHealth

    FYI - I have repaired systems using the last command even though problems weren't found with the first 2 - so I suggest running them all.

    From this article: http://technet.microsoft.com/en-us/library/hh824869.aspx

    You can also run sfc.exe /scannow from an elevated (Run as administrator) Command Prompt to check for further corruption.


4 - RESET using the "Keep My Files" option (W8 calls this a REFRESH; W7 and earlier doesn't have this function)

5 - Repair install of the OS (Thanks to FreeBooter!):

6 - RESET using the "Remove Everything" option (W8 calls this a RESET; W7 and earlier doesn't have this function)

If using W7 or earlier, this can be accomplished by resetting the system by use of the recovery partition/recovery disks/recovery drive.
If you don't have them, you can usually order them from the OEM manufacturer of your system ( US points of contact here:  http://www.carrona.org/recdisc.html )

7 - Wipe and reinstall from the Recovery Partition (if so equipped)

8 - Wipe and reinstall from Recovery Media - to include deleting all partitions.
If you don't have them, you can usually order them from the OEM manufacturer of your system ( US points of contact here:  http://www.carrona.org/recdisc.html )

Use the free Media Creation tool to download a bootable copy of W10:  https://www.microsoft.com/en-us/software-download/windows10/.

You'll be able to access Startup Repair when booting from the drive.

I'd suggesting posting in the Windows 10 forums if you're interested in fixing the BCD.

My attempts at this have been less than successful :0(
