Hello everybody,
I installed Centos 6.2 on a computer with an older version of it in
order to dual boot both of them. I managed to install the new OS on a
physically seperated hard drive, and configured grub to make the newly
installed OS the default one. Now the older OS won't boot and this
error message shows: *"error 13: invalid or unsupported executable
format"*.
I attached to the email the output of *"fdisk -l"* and a copy of the
*"/etc/grub.conf"* configuration file.
I have no experience dealing with boot/grub issues, so any help on this
will be much appreciated.
Regards.
