Hacking Black Screen at boot menu, I am lost... :/

[Mc_Burt]

Hello,
Sorry if the sujbect already exist, I search since 2 days and I haven't find solution.
Since 2 days I have a problem with my switch and my SX PRO. When I start my switch with the SXPRO, the boot menu appears normally, I run "custom boot FW" as usual, and after nothing else starts. The screen remains black. I can not understand why. My dongle is loaded, I am in 8.1.0 system and I have version 2.8 of SXOS.
If I start my switch normally, everything works normally.
I have format again in FAT32, I tried to leave just the boot.dat: nothing is black screen.

Does anyone have a solution to my problem? Thank you in advance ! ^^

Problem identified, out of curiosity going into data manager, I noticed that my card was not recognized. I tried with a news and it was the same.

I finally realize that there is a problem of connection with my switch because when I leave this one down it is immediately recognized ...
