Coolmeesje Posted November 8, 2019 Share Posted November 8, 2019 (edited) Hi Unraid Community, I'm currently trying to build my first Unraid server and I've come to the point where I want to install Unraid. During the setup of the Boot USB I've stumbled upon some inconveniences: Firstly the USB creation tool doesn't detect the (formatted to FAT32) USB Stick: So of course I tried doing it manually which gave me a "MBR DENIED" error: After some research I didn't find anything that could help me nor at all... Could someone please help me out? Yours sincerly, Coolmeesje PS: there is nothing wrong with my USB-Stick since I was able to make it a bootable disk countless times before (for Kubuntu/Win10). Edited November 8, 2019 by Coolmeesje the pictures didnt work and a small spelling mistake Quote Link to comment

trurl Posted November 8, 2019 Share Posted November 8, 2019 Have you tried with a USB 2 port? Not sure it matters when creating the flash on another computer, but I do know many people have problems with flash booting Unraid in a USB 3 port. Also, are you sure there is only one partition on the flash? Quote Link to comment

It's a Usb 2.0 port and a usb 2.0 stick, and I'm sure it has just one partition Edited November 8, 2019 by Coolmeesje more in detial Quote Link to comment
itimpi Posted November 8, 2019 Share Posted November 8, 2019 Have you tried running the USB creator tool or the Cmd.exe in Administrator mode. I believe this is required. Quote Link to comment

(A local store's home brand from the Netherlands) GUID is the globally unique identifier required to assign an Unraid license to the flash drive. Without it you won't be able to use it with Unraid. Not saying it doesn't have a GUID, we don't know. And I don't know if that is any reason it shouldn't be able to prepare it for booting. Might be simpler if you just try a more reputable flash drive.

trurl Posted November 8, 2019 Share Posted November 8, 2019 How large is the flash? 32GB is maximum for FAT32. Quote Link to comment

danull Posted November 8, 2019 Share Posted November 8, 2019 (edited) How about using something like Rufus to pre-format the drive w/ MBR? It helped me when I had a USB stick not recognized during MSI BIOS updates. https://rufus.ie/ PS - I have never had luck with Unraid's USB flash creator, and have always had to do the manual copy of data + makebootable in admin mode.

Thx so much! Ive found a loophole where i made it MBR with a Kubuntu iso using Rufus (the .zip for unraid won't work in rufus apperently). I then deleted all contents that was extracted from the iso. Extracted the unraid zip to the usb drive. Ran the cmd commandline and no more MBR rubbish! Quote Link to comment
limetech Posted November 8, 2019 Share Posted November 8, 2019 Just a theory: virtually all USB flash devices come preformatted with either FAT32 or ExFat. If the device has some other file system, or perhaps no file system or perhaps cleared out MBR then Windows probably doesn't recognize the device in such a manner that function used to populate the device list in our Flash Creator doesn't see it. btw 32GB limitation is only for windows being able to format it using FAT32, larger devices windows will format using ExFat. Our Flash Creator can format devices larger than 32GB with FAT32. Quote Link to comment

leprechaun17 Posted July 15 Share Posted July 15 Hello, I have the same problem to replace my usb drive. Formatted it with RUFUS and no luck. Tried the trick to load Kubuntu as an ISO image with RUFUS and then wiping it and replace it with my USB backup. Still same issue that windows cannot update the MBR when running the make bootable.bat. Can anyone help here? Quote Link to comment
