Grub gone monitor says analogue input

[49]

Hi

I had a problem after last upgrade

I lost my grub table and my PC after it timed out went to linux (Sparky)



I fixed it by downloading and reinstalling latest 3.2 x86 64 e17, previously had 3.1 x86 64 e17

I had upgraded several times which were all ok but the last time it broke the grub display

No problem now except I am concerned that upgrade may break Sparky
