Maybe this is the wrong forum, but please bear with me a little bit. 
This post was sent from a desktop with jessie installed. The problem is 
it will not boot normally. Network booting has been disabled in the 
NVRAM setup. After POST there is a one-liner which says it can not find 
disk. It can be booted with a supergrub2 cd, however.


# fdisk -l

This post is being written with Debian 8 installed on /dev/sda3, above.


Apparently, BIOS does not see a bootable device. In the dim past, fdisk 
could set a partition as "active", which was its euphemism for 
"bootable". However now:


# fdisk /dev/sda

Welcome to fdisk (util-linux 2.25.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.


Command (m for help): a
a: unknown command


Additional info:

# uname -v
#1 SMP Debian 3.16.43-2+deb8u5 (2017-09-19)


HP Pro 3400 Series MT

BIOS version 7.16 dated 03/23/2012 with no update found.


How can /dev/sda1 be defined so that the bios will see it as bootable?


Thanks,
