Sure, updating your profile is best done via Windows. It’s generally safer that way. There’s always a risk of issues, but it shouldn’t completely brick your PC if handled properly.
When power drops or issues arise, the risk remains low. I've applied numerous BIOS updates across a wide range of systems—from Pentium 4 Dell machines to Z390 Intel 9th gen and my latest B550 Ryzen setup. Not once has anything caused a permanent failure. It's not something to take lightly, but it's fairly secure.
Are you asking about a UPS in this context? Unless you're concerned about a sudden power cut during the BIOS update, it's probably not necessary unless you're nervous about system issues. Did you mean to write USB instead? Updating the BIOS through a USB drive is usually the best choice. If you don’t have a USB drive, you can purchase them easily for a low cost.
I understand this situation, but I've faced OEM boards that can't be updated beyond Windows. There was an HP model I wanted to run Linux on, so I had to reinstall the Windows HDD for the update, which was necessary for compatibility. It seems some manufacturers are quite restrictive.
To begin with, all the HP gadgets I've tested can refresh or restore BIOS files using WIN+B when the device is powered on. I've updated my HP BIOS in a similar manner a few times.
It was an HP Compaq dc5700 SFF desktop equipped with a Core 2 Duo processor. The discussions on forums about installing Linux mentioned needing a BIOS update, which could only be performed via Windows.
If you have regular power outages, then a UPS would be recommended. My point on BIOS updates being safe assumes stable power delivery. If there's a reasonable chance of you losing power, then there's a reasonable chance of bricking your motherboard because of losing power. Plus, just generally, getting a UPS for that system would be helpful. I imagine you've lost work before because you lost power.
