proliant gen 8 g1610t install trouble

[hugo31]

Hello all, I just bought a proliant gen8 server, and i have trouble during the install. I put an empty fat32 formatted usb stick in the internal slot and an other usb stick on an external USB2 slot. On the external usb stick there is a ubuntu server distrib. I used unetbootin to put it in. I clearly show the first menu, and i choose obvisouly install ubuntu server. Then ... nothing. Black screen. I don't know what to do. If someone has an idea, please let me know (from the ubuntu menu, when i choose help, i show a lot of command line, then a black screen too) Best regards Hugo
