Install Ubunu & grub in usb pendrive crash when try install grub surface pro7

[tiziano]

Surface pro7
Try install Ubuntu on external Pen Drive for testing it, but i don't want install grub in the
ssd with windows, because i'm not expert of linux and i use de Surface for Work.
When i'm sure Ubuntu is ok for my necessity, i whant migrate all in Linux, but now, i cannot
risk to damage the pc.
Now i resboot and i try the new installation from UEFI... i hope it's ok.
Thank's for all.

Bye
