[Bug 277903] Re: Missing Operating System [message at boot]

[TJ]

Replacing the original isohdpfx.bin in sector 0 of the USB mass storage
device containing the Desktop ISO image of 14.04 and 15.10 with the
alternative isohdpfx_c.bin provides the desired workaround: Holding down
Ctrl as the bootstrap code is loaded by the BIOS forces use of drive
0x80 and the ISO image starts correctly.

If we can get this used in the standard CD images it gives the user a
valuable workaround for this buggy BIOS behaviour.

We also need to document it  - need to identify which Wiki pages require
editing, and now to add instructions to the Release Notes.

Title:
  Missing Operating System [message at boot]

Status in Ubuntu CD Images:
  New
Status in syslinux package in Ubuntu:
  In Progress

Bug description:
  I'm reviving this report since the issue is still present in 14.04 and
  15.10 syslinux, which is used in the various flavour hybrid ISOs, via
  mbr/isohdpfx.{S,bin}

  The same system I originally reported in comment #30 is still
  affected.

  Original upstream discussion (March 2009):
  http://www.syslinux.org/archives/2009-March/012254.html

  Peter reworked the patches in 2009 and created additional MBRs with
  the suffix "_c" (press Ctrl to force disk 0x80) and "_f"
  (unconditionally force disk 0x80).

  These images are in the Ubuntu 14.04 package but were removed (in
  Debian) with:

  syslinux (3:6.03~pre19+dfsg-3) unstable; urgency=low

    * Also skipping isohd*x_{c,f}.bin in syslinux-common.
