I should start by apologising for the length of this post and for the fact that I'm probably going to come across as a bit of an idiot. Although it's true I definitely have my moments, I just really want to get this right and not brick my mobo, especially given that I don't have a replacement system should this one fail. I should also thank anyone for reading this and for any advice you may be able to offer me!

I have a i7 13700k, so I need to update the BIOS so the chip doesn't fry, but I'm terribly nervous about the whole thing having never done it before. It doesn't help that I keep reading posts about how MSI boards are inherently bad at taking BIOS updates and have a nasty tendency to brick when they do, but a lot of the information I am getting on how to actually go about it is often contradictive. It's hard for me to separate the wheat from the chaff. It also doesn't help that I'm a complete amateur in general when it comes to computers.

I have an MSI B760 Gaming Plus WIFI (LGA 1700) DDR5 ATX motherboard. I think I'm right in taking the update from this page: MSI Update? I also bought a 3.0 32gb USB and formatted it as FAT32. As far as I know, the best way to do it is to go through M-Flash after copying the update onto my USB.

I just have a few questions about things I'm genuinely confused about:

1) I think my board has a dual bios, but I have no idea where the switch is. Due to moving house I don't have access to the manual right now and can't seem to find any information about the location of the switch when I search for it. Should something go wrong, this would be handy to know.

2) Is a 3.0 USB okay? I don't have a USB socket reserved for flashing as far as I can tell, so I'm guessing picking a socket at random to do the flash through is okay?

3) Searching for info on how to flash a BIOS has led me to the understanding that I need to update the ME firmware too. I have checked through device manager and my current version is out of date. I'm okay with updating it, but should I do it before the flash or after? Advice on the net differs greatly and I have no idea which order to do it in. I have even seen people insist that if you flash first and do the ME update second, you have a bigger chance of bricking your mobo, but the MSI site insists the correct order is to flash first and update ME later. There's also suggestions that the firmware update is maybe included in the BIOS update, but I'm not certain about that either. I can see it below the BIOS update on the download page, but it doesn't say anything about it. Also, will I need whatever the "update SOP" is?

Any advice at all would be appreciated!

You can get holy bible of PCs from here,

No dual-BIOS for your MoBo though.

Holy bible of PCs, pages 50 and 51 have the guide to update BIOS.

Page 21 shows back I/O connectors. Doesn't matter much which one you use, but i suggest using the ones labeled #9.

ME firmware should be included with BIOS update. If it isn't you can update it after flashing BIOS.

Also, will I need whatever the "update SOP" is?
No. Should be included with BIOS update.

Bricking MoBo with BIOS update is very much a reality. Due to this, most MoBos never see a BIOS update. Unless there is a critical flaw that the BIOS update fixes.

When BIOS update would be interrupted for whatever reason (e.g power loss), your MoBo will be bricked since PC won't run when MoBo has corrupt BIOS. And only fix is MoBo replacement. If lucky, you can roll back the BIOS update, if your MoBo has that feature (which i don't see your MoBo having).
