[SOLVED] Boot failed: Failed to load ldlinux.c32

[natiz 0]

Solution: Re-formatting the flash to FAT16 (FAT) using Windows. (source)

 

 

Hi,

 

I decided to upgrade from 5.0 to 6.0 beta 12.

 

I followed the instructions listed in readme.txt, copied the files, and ran make bootable.

While trying to boot from USB I get this: Failed to load ldlinux.c32

 

At first I thought it was a Mac OS thing, so I did the same process using WinXP, but the same error appears.

I also did a fresh install, without copying my previous config folder (from unraid v5.0)

 

What am I doing wrong?

 

Here's the log from the make_bootable on mac:

 

INFO: make_bootable_mac v1.1

If it makes any difference, mobo is GA-P35C-DS3R

 

Also, clearly the file is created:

 

EDIT 1:

Just noticed there was another thread opened about this issue, for a different Gigabyte mobo.

I tried copying the libcom32.c32 file, as suggested, but the same error appears.

Try putting these additional files from the download on your flash and run makebootable again:

 

syslinux folder with all contents

make_bootable_mac

make_bootable.bat

Not sure I understand what you mean, these files are already on the flash drive. The above screenshot shows the content of the flash drive (not the download folder)

I ran make_bootable_mac multiple times, same error occurs.

I saw your screenshot. Are all of the files I mentioned from the latest download, or are they from a previous install?

All the files are from unRAIDServer-6.0-beta12-x86_64.zip, which I recently downloaded from the downloads page.

I formatted the flash before copying the files

My 6b12 flash doesn't even have a ldlinux.c32 file on it and it boots fine.

All the files are from unRAIDServer-6.0-beta12-x86_64.zip, which I recently downloaded from the downloads page.

I formatted the flash before copying the files

Those files do not reflect what I see for beta 12.    I have a syslinux folder, and inside that are a number of files relating to syslinux

I'm guessing that both of you are using windows, hence not seeing ldlinux.c32 and ldsyslinux.sys which is created once running make bootable.

 

For clarification, here's the full flash directory:

So I went back on memory lane, to when I initially installed unRAID.

At that time, I had a different syslinux error (no conf file found), which was solved by re-formatting the drive to FAT16.

I believe it was this thread which gave me the idea.

 

So the solution was simple re-formatting the flash (using Windows, can't do it on Mac) to FAT16.

This info was great and pointed me in the right direction wanted to provide an update for any other Mac users that ran in to the same issue.  There is a way to format the flashdrive to FAT-16 after letting the Mac erase the drive and create the single partition with the name you need.

 

After using the Disk Util to erase the drive you can run the following commands to find the partition and then reformat it to FAT-16 from a terminal

 

diskutil list

=========== example output============================

/dev/disk1

  #:                      TYPE NAME                    SIZE      IDENTIFIER

  0:    FDisk_partition_scheme                        *1.0 GB    disk1

  1:                DOS_FAT_32 UNRAID                  1.0 GB    disk1s1

================================================

 

once you identify the partition you can then run

 

sudo newfs_msdos -F 16 -v UNRAID /dev/disk1s1

=========== example output============================

newfs_msdos: warning: /dev/disk1s1 is not a character device

512 bytes per physical sector

/dev/disk1s1: 1957344 sectors in 61167 FAT16 clusters (16384 bytes/cluster)

bps=512 spc=32 res=1 nft=2 rde=512 mid=0xf8 spf=239 spt=32 hds=128 hid=2 drv=0x80 bsec=1957886

================================================

 

you can ignore the warning about not being a character device and even when you run diskutil list it will show as DOS_FAT_32 its actually FAT 16 and was able to get past the missing file.
