bios vs efi setup

[kalpana]

Hello everyone.
I recently acquired a rather old dell desktop, probably 2012 or so. It is bios only, as far as I can tell. The only mention of "efi" in the bios, that I can find, is the option to boot into an efi shell. My question is, is there any reason not to use a bios only computer. I understand some of the limitations, like only 4 primary partitions, but is there any major issue with running this system.

Without booting it, I'll work from memory here. The specs are:
64 bit
Intel processor running 3.4 GHZ, 4 core, 8 thread
8GB of ddr3 memory
integrated intel graphics(I believe it said hd 4000)
descrete graphics card, gforce with 1 GB onboard ram
1 sata3 and 3 sata2 connections

So, again, I'm curious as to whether I I am going to run into any issues with this. I installed lubuntu 20.04 and fully updated, then did a release upgrade, all went well as near as I can tell.
This is a temporary setup, as I plan to but a MUCH newer system, I just have to work it into the budget.

Sorry if this isn't the proper place for this, if not, please move to appropriate sub-forum.
Thanks in advance.
