Installing Product Suite boot loader   
Hi:

I have a customer that has a dual boot QNX Product Suite 2009/Windows XP computer.
Every so often something happens whereby the boot loader gets destroyed and they can only boot into Windows XP.
Is there a way using the QNX Product Suite CD to place the boot loader back onto the computer so that the choice of 
which OS to boot is back in place.
Currently they have had to reinstall QNX when it happens.
We have yet to determine the cause of the boot loader becoming corrupted.

- Thanks,
  Kevin

Next scheme work on booting:

1. BIOS choose boot devise
2. boot devise MBR loader (winloader in our case) choose which partition to load
3. partition loader (qnx partition loader in our case) load OS

What goes wrong?
qnx partition loader corrupt or winloader can't choose QNX partition?

Re: Installing Product Suite boot loader   
The QNX boot loader does not even appear anymore. You are booted into Windows XP automatically.

I could not recreate the customer issue so I set up a dual boot system
and then found information on how to remove the QNX boot loader using a DOS command:

fdisk /mbr

This did remove the QNX boot loader.
 I then tried to use the QNX Product Suite CD to mount the QNX partition.
After the mounting occured I opened up a shell window and typed:

fdisk /dev/hd0.0t77  loader

to put the boot loader back on but this did not work.
The QNX boot loader did not reappear on startup.

Hi!

Another possible solution is learning ntldr (Windows NT/2000/XP loader) to 
boot QNX.

1. Save first sector from QNX bootable partition, for example:

# dd if=/dev/hd0.0t77 of=./bootsect.qnx count=1

2. Place bootsect.qnx into the root directory of Windows disk C.

3. In Windows, edit boot.ini file and add following line in [operating systems] 
section:

C:\bootsect.qnx="QNX 4.25"


After all these actions you'll get "QNX 4.25" menu entry in your Windows boot 
menu. This receipt also works with QNX6.

Oleg
