Having recently installed Ubuntu 20.04.02 LTS, the new experience is rather disappointing.:
sluggish in booting;
when transferring volumes of data, such that a progress-window appears in previous Ubuntu, there is no such item now - only a small blue rotating disc/arrow: very slow
(with older Ubuntu, one could make tea and observe from a distance).
I found my current BIOS is old, namely A07.
The latest is A16, with interim BIOS updates necessary - firstly A08.
I downloaded the file --M4500A08.EXE-- and popped it on a thumb-drive. But booting to this resulted in a screen remaining black and a blinking cursor. Nothing happened for several minutes, before I terminated the process.
I did then boot to Ubuntu with no further trouble. So, A07 is still working.
Does A07 have a virus? How can one ensure it is clean?
and, finally, PLEASE:
How should I properly update the current BIOS to A08, then A09, eventually to A16?
I am quite frustrated. Dell’s URL pages drives one into a reference loop …
