Ah, this is nicely descriptive.  Thank you.

It may be that you can recover Linux.  You said in the beginning that
you resized and increased the size of the Linux partition.  Whatever you
used must have changed the partition type on the bigger /dev/hda2.

You can try to make the type into ext2/ext3.  They are the same really
except that there is a journal on ext3. To do this, you will need the
Linux fdisk.  Do not use Windows fdisk; it is very different and will
destroy the data.  Linux fdisk will rewrite the partition table, but
will not destroy data.

You need a floppy with Linux fdisk on it.  This is the rescue disk I
love to mention.  Since you use a floppy drive, I'd say for you to get
RIP or Tom's.  I have the link for RIP.  Just get the floppy version as
it will be quicker for you to deal with.  Put it on a floppy as per
directions. If you already have a cd linux with fdisk on it, then that
will be fine as well.

When you have the rescue linux running and are not mounted on your hard
drive, as root run

fdisk /dev/hda

'm' gives you the command list
'l' gives you the type list.  You want 83, Linux type.
't' allows you to change the type.  Choose partition 2 and give it type 83.
'w' this writes the partition table with the new information.

Then try grub again.  It might just work or you might have to try
commandline grub.

Let us know what happens, please.
