Nexus 5020 - "loader" state, can't load any nx-os image

[Ron Baduach]

Hi Guys, my name is Ron , and I'm working at Cisco .

We got Nexus 5020 , that someone erased all of the boot files [i think he did "erase boot"] .

Now, the Nexus is on "loader>" prompt , and i just can't load any image .

1. I tried to configure it IP ["ip set x.x.x.x 255.255.255.0" and also DG] , and i saw that it configured, but I still have no ping, so I can't load an image [the Uplink switch even don't see the Nexus's MAC...] 

2. I tried to load image from USB Disk-On-Key , also without success, because when I press on "dir" , the only thing I see is :

loader> dir
bootflash:
lost+found

I suspect that there is some hardware failure [because there was also electricity down, but don't know how to make sure what is wrong]

Any assistant will be appreciated  ! It's important to us, because we need to build a new Data-Center .

Thanks in advance ,

Ron
