I just installed Patch A. I noticed the same thing
as with previous public beta.
When installing from the CD-image into a QNX partition,
and choosing not to install the QNX botloader,
the bootable flag is moved to the QNX patrition anyway.
This is obviously not what I want as the machine won’t boot
at all now.
To fix the problem I use a Linux boot/rescue disc with
fdisk to move the flag back…
