Won't boot after 6.8 update

[ganey]

I've been running 6.7.2 mostly fine for some time now (apart from my plex sqlite db giving up every so often.

 

I checked all the plugins, dockers etc for updates before proceeding with the update to 6.8.0

 

The server will no longer boot.

 

I've tried restoring a backup from earlier today before the upgrade to the same USB with no luck (I've tried this with the tool on mac & windows, and manually)

 

So far seems like my original USB (4gb hp)  is dead which is fine, i have some others about.

 

 

 

I've tried a couple of other USB sticks too (4gb integral and a 16gb lexar) and these boot to the unraid menu, but then seems to either reboot, or show me a ton of green squares. The green squares don't bother me too much as i've had that output since day 1. annoyingly though I can't tell if there's any errors.

 

Is there a boot log anywhere I can check? Any suggested next steps?

 

It's a Core 2 Duo E8400 @ 3.00Ghz with 8gb ram on an Intel DQ35JO

Try to run the memtst option from the Unraid boot menu.  Twenty-four hours is usually the recommendation with zero errors.

Initially the memtest kept failing so I tried it in other computers with no luck. 

 

I tried a completely different Windows pc to fresh install 6.8 on a USB and then memtest worked successfully. 

 

It booted fine into unraid safe mode so I copied over my config backup and so far everything seems good on 6.8, also no more green squares! 

 

 

I have no idea why but it seems neither of my mac book pros or my Windows 10 laptop are any good for making the USB. I tried with the tool and manually on each of them

 

 

TLDR: 4th computer is the only one that can successfully create a working USB.
