I don’t just do macs, I do Windows. And moving to Windows 11, I needed to replace my Intel 7th generation logicboard. I decided to go with ROG ASUS

, having a previous ASRock TaiChi that was only 4 years old…but unsupporting Window 11.
Reading ASUS forums on the webs, and watching some youtubers, I found that ASUS has a clunky, annoying Updating application called Armory Crate. Logic says to avoid it, but one will need to visit Asus for drivers and updates to perform manually. Since my MLB (main logicboard) is a ROG (republic of gamers) STRIX X670E-E, I am linking to the support page.

Wouldn’t you know it, that on 2nd update to the BIOS (version 1602, 8/18/2023, 9/24MB). I received “selected file is not a UEFI Bios”. WTF? It IS TOO! After researching, aka googling/duckduckgo, I found that the best option that worked for me was to make a USB flash drive formatted in FAT32, then extract the file with 7-ZIP since others noted better success than Windows Extract. That file would be a long name with a .CAP extension. Along with that file is a BIOSRenamer app. Run that app as Administrator in the same folder the files were extracted to, and it will rename it to a short nnnnnn.CAB file. (nnnnnn will be a name of the board e.g. SX670EE where my StrixX670E-E is the model).

Boot into Bios (F2 or Del key at restart as ROG logo appears, select Advanced in the lower right (yes, the cursor is WONKY) and then Tools. Select the Asus Bios Utility, navigate to the USB flash drive (remember its size incase you have more than one volume) and select the .CAP file. It will prompt about making sure Bitlocker is disabled. IF you aren’t sure, exit out to restart and check your Windows setting of Bitlocker. For my gaming home machine, I don’t have it bitlockered. If Bitlocker didn’t matter to you, as it didn’t to me, proceed with the BIOS update. Mine took about 10 minutes and then a restart. Then to a bios “do not power off” screen … good practice is to have your PC on a UPS. Once done, it restarted to ASUS bios updated, press F1. Then it takes you into BIOS. Don’t exit just yet! Every UEFI BIOS, ASUS turns on Armory Crate download to ENABLED. Find that in Advanced/Tools and set to DISABLE. Then Save and Exit. On that, another restart and I was in to the Windows 11 login. SUCCESS!

Thanks to others for this tip. Hope it helps!
( I recommend a 16-32GB USB 3.0 flash drive, formatted to FAT32 for ASUS bios updates.)
