Unable to boot from HD

Hi,
We have a embedded PC on which we’ve just changed the HD to a 1Gb
flashdisk. After I installed qnx4.25 on it, I can only boot from a
floppy. When I try to boot from the HD, I get the message:
"
Loading partition 4
press ESC for alternate OS…???
"
or something like that. Then it gives me a error msg relative to the
mount cmd, and freezes.
I know I had a similar problem a few monthes ago, but I can’t remember
how I solved it.
So the first question is: What exactly is the meaning of the question
marks ?
Thanks in advance

Try an old bootloader

‘dinit -b -O /dev/hd0t77’

Thanks Dieter for the reply.
I solved the problem: The LBA mode was configured to give more than 1024
cylinders :frowning: I changed that and it worked.
By the way, just by curiosity, do you know the meaning of the question
marks when booting? I figured it was an error, but what kind of error is
that supposed to represent ?
Thanks again.
