Booting Linux from its HD partition using IBM Boot Manager

Booting Linux from its HD partition using IBM Boot Manager

Post by Jim Ki » Wed, 11 Dec 1996 04:00:00



I've just finished installing Slackware Linux '96 onto a Linux primary
partition of an IDE drive.  Everything works great when I boot from a floppy.  
When I try to set up IBM Boot Manager (that came with Partition Magic 3.0) to
boot the Linux partition, I get a "non-system disk" error.  Basicly this boot
manager shuffles the active partition.  You set the manager itself as active,
then it points to the partition from which to boot.

Can someone point me in the right direction to get Linux to boot directly from
the hard drive?  Is this a Boot Manager problem, or do I need to do something
special with my linux partition to get it to boot directly?

I've been using the Boot Manager that comes with OS/2 for years to do
exactly that (I assume it's the same one, based on your description).

Install the Boot Manager and create your partitions, including the Linux
Partitions, using the IBM tool, then when you get to the Linux fdisk, just
change the type to 83 and install LILO on the MBR of the Linux partition.

For grins, I've even set up LILO on the MBR of the disk, when could then
boot any OS, including the IBM boot manager!

Last night, in the course of installing RedHat 4.0 (a process I'm VASTLY
underwhelmed by, so far), I ran into "Partition is not formatted" when
I tried to boot the new "Successfully" installed redhat, and had to edit
lilo.conf by hand and then do a `lilo -r` from my slackware partition to
get that working, at which point it would make it through the LILO portion
of the boot, at least, just fine.


more details.

You have to set up LILO on you Linux partition.  It takes over from Boot
Manager and actualy loads Linux.

You need to configure and run LILO.  Install it to the boot record of
you Linux parttition, not the master boot record for the drive.  There
is an option for it in the Slackware setup menu.

1. Partition Software - Partition Magic, Bootit, Boot Manager or Ranish Partition Manager


spake unto us, saying:

By default, Solaris and Linux will not be able to see each other, and
the Windows flavors will not be able to see either one.  So your only
concern will be the visibility between NT and Win95.

If you install those two in primary partitions on the same drive, there
shouldn't be a problem with that either.

Bootit is a utility I know of but have not used.

The only "Boot Manager" I know about is the OS/2 Boot Manager (also the
same as the IBM Boot Manager included as part of Partition Magic 3.x),
and it's a nice basic boot menu, but I'm not sure it's available at all
as a separate product.  I've used it for years (since 1992 I think).

Partition Magic is a glorified (and relatively powerful) fdisk utility
which I've used for quite a while.  Very useful, IMhO.  Newer versions
have things I'm not familiar with (I'm still using the OS/2 version of
PM 2.03).

Ranish's Partition Manager looks like a REALLY slick utility, and it's
on my list to play with.  But I copped out and bought a copy of System
Commander here instead.  :-)

I think I would recommend that you add System Commander to your list
above, since it allows you to selectively change primary partition
visibility (in many cases) for each individual boot menu entry.

Really, though, you probably don't need it.  The only question I would
have is how to get NT's boot manager to get along with Solaris' boot
manager, and I suspect that can be done.
