Flash BIOS without a CPU...
Easiest way to update BIOS without CPU or flashback
BIOS update no cpu or flashback
What happens if BIOS does not support the CPU?
Then that means the user will have to update the BIOS to a firmware that does support that particular CPU. You can take 12th Gen Intel Motherboards, for example. It supports all of the 12th Gen and 13th Gen CPUs. But you will need a BIOS update to use any 13th Gen CPU on 12th Gen motherboards.
How do I update my BIOS if my computer won't boot?
You can either try the UEFI BIOS update method or simply try the USB BIOS flash without CPU option. This means you will still need another PC or laptop to download the BIOS to a FAT32 USB. Then use the UEFI or BIOS flashback button/USB header at the back.
Can we update BIOS without OS?
Yes, you can update BIOS without the operating system. But you need another PC or laptop to format the USB into the FAT32 file system. That means users will have to use another PC to download and prepare USB to upgrade BIOS on a PC without OS.

I'm gonna flash BIOS using the button on my MSI motherboard. It's my first time building a PC and I get a little bit nervous, so I just want you guys to help me check if the process is correct.
-
download the bios file, rename it and put it into a FAT32 flash drive
-
put on power cables onto the motherboard (I think there are 2 cables, one big and one small?)
-
turn on the power
-
plug the flash drive into the correct USB port
-
push the button and wait
-
until it indicates the completion, I can unplug the drive and turn off the power
Thank you!
Im facing a bit of a dilemma right now, the mobo I’ve bought most likely doesn’t support my CPU out of the box and doesn’t have a BIOS flash feature, I also don’t have a compatible CPU. As far as I can tell, my options are:
-
Return my CPU and get a 13th gen CPU instead - would cost about £50 but I'm not sure I’ll be able to get a refund as I bought it before Christmas.
-
Return my mobo and get one that supports 14th gen CPUs or has a flashback feature - would cost me about £60 more to buy a MSI PRO Z790-P which has M-Flash.
-
Buy an older CPU and update the BIOS with this CPU – I can get a Celeron G6900 for about £66 which I could probably resell for about £30, but this would mean having to install a CPU fan more than once which seems like a hassle and more chance of me effing this up.

Take it to a PC shop and get them to update the BIOS – not sure where around me that could do this and how much it would cost, but potentially the easiest solution.
This is my first PC build so I’m looking for the easiest solution, which feels like buying the Z790 mobo. What option would you say is the easiest/least risky? Is there another option I’ve missed? Is it worth trying my CPU first to see if it would post with the current BIOS or is there 0% chance of working?

Edit: Luckily the motherboard came with it as i got it used and was already updated from previous user.
