I've tried to install a BIOS update to version 349. After installation and reboot the NUC stops with black screen and flashing underscore character.
I was downgrading to version 249 and the NUC was working. Now I've tried to upgrade to the newer BIOS version 350. Same issue and I had to downgrade to version 249 again.
The OS was upgraded (automatically) from Win8.1 to 10 in the meantime. No other changes on system.
HDD: m2 Samsung SSD XP941 128GB
Any hint, why the BIOS upgrade will not work?
Thanks!
