Can't boot USB

[ssn760]

Hi,

I run Majaro on my personal laptop, and I wanted to try Unraid on my home server.  I'm having a bit of trouble however.

 

I followed the directions linked here (5th post down by Bob1215) to create my USB stick.  According to the feedback I get from running the make_bootable_linux script, everything is good to go:

[dave@dave-msi unRAIDServer-6.8.3-x86_64]$ sudo bash make_bootable_linux 
INFO: make_bootable_linux v1.3

INFO: The following device appears to be the unRAID USB Flash drive: /dev/sdc
INFO: Temporarily mounting unRAID USB Flash drive to /tmp/UNRAID_TMP_MOUNT
Permit UEFI boot mode [Y/N]: Y
INFO: unRAID USB Flash drive currently mounted to /tmp/UNRAID_TMP_MOUNT, copying temporary installer files to /tmp/UNRAID

To continue you may need to enter your admin password

447 bytes copied, 0.00018543 s, 2.4 MB/s

INFO: the Unraid OS USB Flash drive is now bootable and may be ejected.

 

However, when I boot my machine using this disk (I've tried it twice now) I get the following error:

 

error: invalid arch-independent ELF magic.
Entering resue mode...
grub rescue>

Do you guys just have an ISO I can dd onto a USB stick?  I only saw the zip.  Yes, I did install syslinux:

 

[dave@dave-msi unRAIDServer-6.8.3-x86_64]$ pacman -Q | grep sysl
syslinux 6.04.pre2.r11.gbf6db5b4-3

 

 

Thanks in advance!

There is not a single solution to this type of problem.  Which is probably the reason that no one else has jumped in.  Let me just list some of the possibilities.

 

1-  The Flash Drive is not properly configured. 

 

2-  The flash drive has more than one partition on it.

 

3- The MB does not support UEFI booting.

 

4- The MB BIOS's UEFI mode is not properly configured for booting from the Unraid boot disk.

 

One of the first things you should try is to see if the flash drive will boot in another computer.   (Unraid will not write to any disk unless you have specifically given it permission to do so.  Hence, it will not disrupt anything on the disk(s) on that computer!)

So, none of those 4 were the culprit.  The only way I could fix the issue is by grabbing my wife's windows laptop and running the usb creator utility.  It's a bit disappointing that a linux based OS doesn't provide a linux utility (or an ISO) to boot it's OS.  

 

My suspicion is that the issue was due to the fact the thumb drive I am using is 32GB, which is right at the limit specified by the manual method on the getting started page.  But the motherboard is an Asrock x470 Taichi Ultimate on BIOS version 3.40, so really recent.  I also double checked the drive was formatted properly in gparted, and that the boot flag was on.
