Ok, let me start off with I have read many of the older forum posts and here is what I tried, but no matter what I keep getting the "Bzmodules checksum error".

1. Obtained new USB drive

2. Used tool to create the boot media (7.1.4)

3. Inserted into USB port on system

4. Failed

5. Re-did USB drive and tried new port. Repeated this for every USB port on the system and got the same results.

6. Manually ran diskpart cleaned the USB drive, formatted to fat32, copied over files for 7.1.4 (downloaded clean version from site), ran the make bootable

7. Same error, did the same as step 5 with manual diskpart, format....etc.

8. Tried a new drive - Rinse and repeated (did not go through every port, but a few)

9. Tried 2 more drives - rinse and repeated. Drives ranged from 16GB - 64GB, most being 32GB

10. In the middle of all that, I even replaced my system memory for the heck of it

This issue is frustrating me, as of posting this, I am going to create the USB from another system just incase there is some oddity on the computer I am using to make the USB's (would be odd this is the only drive that has issues, but I have been in IT to see weirder things). I just wanted to get some other ideas.

My motherboard is a ASRock Riptide X570 hosting a 5700G proc. Not sure if anyone has seen any oddities with that board and proc. Again, I am grasping at straws trying to figure out this issue. I have been using UNRAID for well over 10 years, and multiple unraid servers. This is the oddest and most frustrating issue I have ran into at this point.

Have you actually tested your RAM?

If you have multiple sticks try booting with just one, if the same try with a different one, that will basically rule out bad RAM.
