Linux taken over by Win95

Post by Michael Carmo » Fri, 26 Jul 1996 04:00:00



Hello All,

I've loaded win95 after having loaded Linux and OS/2.  I'm using the OS/2
Boot Manager.  Now the Boot Manager doesn't come up, it boots right into
Win95.  Fdisk /mbr has no effect.  How do I get OS/2 Boot Manager working
again?

Thanks in advance
Michael

For OS/2 2.11, the installation guide says:
* Boot from installation disk.
* When asked, insert disk 1 and hit RETURN.
* When main menu appears (asking you if you want to partition your disk),
  remove floppy and reboot.

This worked fine for me.
Hope this helps.

Actually, Win95 probably just set its own partition to be the bootable
partition; Boot Manager is likely still intact, but will never "boot."

This should work.  A simpler solution would be to use Win95's FDISK to set the
Boot Manager partition as "startable" or "bootable" or whatever similar
terminology Win95's FDISK uses.

Big deal.  Both Linux and OS/2 are happy booting from extended/logical
partitions, and 1MB of disk space isn't all that much by today's standards.

Quote:> True, LILO doesn't have the fancy menu of
> Boot Manager, but it works just as good (IMHO).

Last I'd heard, LILO couldn't boot OS/2 if OS/2 was installed on an
extended/logical partition formatted for HPFS (maybe FAT, too, but I'm not sure
of that).  If this is still true, it evens the LILO-vs-Boot Manager playing
field in terms of primary partition useage, leaving only the 1MB (or sometimes
2MB or more on large drives) disk space advantage for LILO.  The differences
really aren't that great in terms of objective requirements.

Bottom line, IMHO:  Use whatever works best and whatever you're comfortable
with.  For some people it'll be LILO, for others it'll be Boot Manager, and for
others it'll be something else.  This "my boot loader is better than yours"
debate is really even more childish than the "my OS is better than yours"
debate.

Exactly the same thing happened to me -- though I was expecting it, having
heard how rude Win95 is.

My solution was to:
 1) boot linux (either with a floppy that you prepared earlier... or
    if you have a CD with a linux kernel and LOADLIN.EXE you can boot
    from Win95 DOS mode.)
 2) install/modify LILO to be able to boot OS/2 (from /dev/hda5 in my case)
     - /etc/lilo.conf needs to have a section "other=/dev/hda5
                                                  label=os2"
    (you could choose to install LILO on the MBR and make it your boot
        manager.  I wanted to bring back OS2 Boot Manager.)
 3) boot OS2 (by interrupting LILO and typing "os2" at the : )
 4) run OS2's FDISK and re-install Boot Manager

The LOADLIN & LILO documentation gives full details.  Best of luck.

        It looks like you gotta install Boot Manager again 'cause Win95
hosed it during installation.  Just use your OS/2 boot disks to load up
OS/2, then use OS/2's FDISK to put Boot Manager back in.

        But why use Boot Manager?  Just use the Linux Loader, LILO.  For
one thing, LILO doesn't need a whole friggin' 1MB partition (and a
primary partition at that).  True, LILO doesn't have the fancy menu of

Michael,

   One of the great?? Windoze 95 features that MS slipped over on us
   is the one (don't know if it's documented) that waste's the ability
   of any other disk partition to be booted at power-up.  You will
   need to re-install the OS/2 Boot Manager and re-add your bootable
   partitions.  As yet, I haven't determined if entering Windoze 95's
   setup AFTER installation will do the same, I sure hope not.

                                      -Richard

Nope, Win95 overwrites the MBR. Sort of Mickeysofts way of telling
people "Who needs another OS?" ;-)

Nope that's wrong. When I installed Win95 all I had to do was run Win95's
fdisk and reset the Boot Manager partition as the bootable partition.

Hell, the Windows 95 install readme even tells you all of this!

This isn't true. You do *not* have to re-install OS/2 Boot Manager
after installing Windows 95. All you have to do is use Win95 fdisk
to set the Boot Manager partition as the boot partition and that's
it, it's that simple.

Win95 even tells you this will happen and the whole scenario is
documented in the Win95 install readme.

I know this to be the case, this is what heppened to me. Install 95,
only 95 boots. Run fdisk, reboot, boot manager appears, choose from
Win95, OS/2 or Linux. Simple!

: Nope that's wrong. When I installed Win95 all I had to do was run Win95's
: fdisk and reset the Boot Manager partition as the bootable partition.

I have to confirm that this is true... Win95 *may* overwrite the MBR, but
that isn't where Boot Manager is to begin with!  Boot Manager simply resides
on another [primary] partition and is set as the active partition in the
partition table.

As with MSDOS, Win95's installation program just sets its partition as the
active partition.  This effectively bypasses boot manager.  Hence, the fix
is exactly as it is for MSDOS - select the boot manager partition as the
active partition, so it gets to boot before Win95.

1. Taking The Plunge: Win95->Linux

I'm bored.

So, I decided about 6 months ago to begin building a slave machine to
perform experiments on. Nothing special, a 486/40 with 4MB of ram, 170MB
IDE hard disk, no goofy or weird hardware to get in the way of
installation; its all standard stuff.

My goal is to get a basic Linux install up and running off it, possibly
permanently if it works out.

I'll be using the CD-ROM off one of my other machines for the
installation..Again, just a basic install.. I probably wont even bother
installing X.

Could someone provide me with a few nice looking screenshots of what a
-good- Linux desktop (running X) looks like? I'd like to see what you guys
are up to. You know, bring up a few windows, a couple small apps, just so
I can get a little preview of what I'm working towards. Feel free to send

If the installation of Red Hat on my slave machine works out well enough,
I may switch over to Linux on my other (main) PC, a fully blown out
Pentium box with 40MB of ram and enough goodies in it to make a grown man
squeal like a little girl. :)
