[syslinux] Boot Error GPT partition

Good day again Keshav,

It might be the case that Syslinx is indeed installed to your /dev/sda8,
since Syslinux itself contains the string "Boot error".  That would
cause me to think that one of the following is true:

1. Your BIOS doesn't support EDD (it is C/H/S only).
2. The checksum for the loaded ldlinux.sys fails.
3. The "magic" signature in the loaded ldlinux.sys fails.

So I would guess that ldlinux.sys was physically moved at some point
(it's starting sector needs to be hard-coded by the Syslinux
installation process into the partition's boot sector, and the file
needs to be contiguous), or the installation process is not recording
its starting sector properly.

It might be worth wiping the boot sector of /dev/sda8 and re-installing

  dd if=/dev/zero of=/dev/sda8 count=1
  syslinux /dev/sda8

(count=1 is _important_, you don't wish to wipe the whole partition!)

The fact that it _did_ work at one point might subtract from theory #1,
up above.
