Syslinux - Dec 2012 - Upgraded to Syslinux 5.00 - Failed to load ldlinux.c32

Hello,

today I upgraded from Syslinux 4.06 to to Syslinux 5.00. But now the
system won't boot anymore and I get the message

  Failed to load ldlinux.c32
  Boot failed: please change disks and press a key to continue


What I have done:

1) Installed Syslinux 5.00

2) Reinstalled "mbr.bin" to /dev/sda and /dev/sdb using

  dd bs=440 count=1 conv=notrunc if=/usr/share/syslinux/mbr.bin of=/dev/...

3) Updated extlinux using

  extlinux --update /boot/extlinux

(I also tried "extlinux --install")

4) Removed everything in /boot/extlinux excluding "extlinux.conf" and
"ldlinux.sys".

5) Copied *.c32 from /ush/share/syslinux to /boot/extlinux:

I don't know if there are additional problems, but the order of those 
steps might be problematic. Your step #4 (which, for 5.00+, should be 
ldlinux.sys, ldlinux.c32 and the relevant config file) should be 
performed before your step #3, so in your step #5 you should NOT be 
replacing files (only re-adding the same files with their new 
versions; not replacing ldlinux.* which were "installed" already).

In other words, when you perform "extlinux --install", 2 files are 
"installed" with Syslinux 5.00: ldlinux.sys AND ldlinux.c32. Then add 
all the lib*.c32 files and all the other relevant *.c32 files you 
were using before, but updated to 5.00.

As said, there may be other issues to consider (raid for example), 
but I would first check this simple change in the order of the steps.

HTH,
Ady.
