May 26, 20224 yr Hi all! I just updated my server to Unraid 6.10.1 after a few days of stability test with 6.10; problem is that now unraid can't boot because of a bzroot checksum error, and I don't know what to do except the basics: I tried to replace the bzroot.sha256 from the usb with the one in the 6.10.1 zip, but no luck with it; I already formatted my USB drive (16GB, FAT32) and tried to use it as is, without having my config/ installed on it, but it failed nontheless. I don't know if going back to 6.10 would fix the problem, but I see no advantage of going back if the new release fixes issues Sadly I don't have any diagnostics zip that I can provide
May 26, 20224 yr Community Expert Want make of server and Nic do you have? Certain combinations seem to produce this error spuriously if virtualisation is enabled in the server’s BIOS.
May 26, 20224 yr Community Expert Solution If it's a Dell server see here: https://forums.unraid.net/topic/119502-bzimage-checksum-error/?do=findComment&comment=1108354

As I currently tried to support a buddy of mine with excatly this error I can confirm that - this NOT ONLY happening to Dell Servers. - intel_iommu=on iommu=pt did not work for him but changed the error massage from bzimage checksum error to bzroot checksum error - intel_iommu=off did not work too What we tried until now: - Updated all plugins, OS Update Check from Fix common problems was OK - Updated within GUI - Restart: --> bzimages checksum error - copied bz* files inlcuding crc files from the 6.10.1 zip to the USB -> bzimages checksum error - Tried the add the command intel_iommu=on iommu=pt to start cfg but that changed the error message from bzimage checksum error to -> bzroot checksum error - We rolled back to 6.9.2 everything is working fine - tried to update again as we thought it was an error in the update process --> Same error as before. - We rolled back to 6.9.2 everything is working fine His Hardware MB: Intel DG45ID CPU: Intel Core2Due E8400 RAM: 8`GB DDR2 GPU: Intel 82G45 onboard Grafik SATA Controller: Onboard NIC: Onboard Edited May 27, 20224 yr by HardwareHarry update hw specs

May 27, 20224 yr So hi there, i am hardwareharry's buddy with the intel-board. PLEASE HELP. what should i do?

I would suggest redoing the flash drive done manually: Backup config folder from flash, then in Windows open a command prompt window as administrator, then type, in this order: -diskpart -list disk -select disk x (x=your flash drive) -clean -create partition primary -format fs=fat32 label=UNRAID quick -active -assign -exit -close cmd window -unzip new Unraid install to flash -restore the previously backed up config folder -execute make_bootable as admin
May 27, 20224 yr Thanks so much @JorgeB!!! i will try in a few minutes and report the result here. just to be sure as newbie: my registration of unraid is stored in the config folder?

I don't see a benefit in doing this as restoring the old 6.9.2 works fine, from the same stick. 11 minutes ago, mastaburna said: Result: bzimage checksum error - press ENTER to reboot ... To me this is a bug in the 6.10.1 the only question is what is the trigger and how can we find a workaround.

May 27, 20224 yr Hi together, welcome👋 Might be the Fix has changed something? Quote Changelog: Version 6.10.1 2022-05-21 Management: startup: fix regression: support USB flash boot from other than partition 1 Did you try with 10.0?
June 1, 20224 yr I am now having this same problem having upgraded to 6.10.2 "stable" from 6.9. Dell R710II. What's the fix? Edit: This seems to work for most people: Edited June 1, 20224 yr by norp90 Added temp comment to temp fix.

Quick and simple! Thank you!
January 24, 20233 yr Related note: I got a simmilar experience. Ill make a induvidual ticket to find out why my updates fail this way. I updated unraid 6.9.2 to 6.11.5 and got the same error. The server did not start after the update and gave me a superblock error. I couldnt get into the server remotely anymore. The device that gave me the error unraid /dev/loop0 /boot/bzmodules error I had to remove the USB from the server and opened it on a laptop. The loop0 seemed to be the bzmodules. So I copied the content of my flash-drives previous folder over the files on the USB. Put the USB in the server, started. At boot the server download/written a file or 2. And then the server started as before. This fixed the error for me. Still cant update to 6.11.5 succesfully
