Lilo boot won't allow DOS to boot

Lilo boot won't allow DOS to boot

I just upgraded my kernel to v1.0 from 0.99.14.

Did the usual make config,
Did the usual make config,
              make dep
              make clean
              make

I followed the v1.0 kernel installation instructions and now I cannot load
DOS when I turn on my computer.  I do not know what all the commands do
(pretty dangerous :)) but when I rdev it says => /dev/hda2.

 /dev/hda1 = DOS partition
 /dev/hda2 = Linux fs
 /dev/hda2 = Linux fs
 /dev/hda2 = linux swap.

I cannot seem to change the filesystem back to dos, even when I boot dos
from my a: drive and use fdisk.  I really do not want to dump the Linux fs
and start from scratch.

I have all the HOW documents but maybe I have missed the right one.
Can anybody tell me what's up?

Most likely your /etc/lilo.config is screwed.  Check it out carefully and
make sure that it makes sense.
The other possibility, of course, is you blundered at some point and
trashed your DOS partition....   in which case I hope you had a backup.

Well i do not have an /etc/lilo.config.

But I can load DOS from a floppy and access my harddrives :) .
Perhaps I will do a DOS backup on tape before I go further and reinstall
linux and do my upgrade a bit more carefully.
linux and do my upgrade a bit more carefully.

I do have more than one distribution that got mixed up.

Thanks for the help.

How is your lilo configuration setup? Did you rerun this?

1. Lilo boot problem: doesn't boot dos (invalid media type)

Hi,
I installed redhat 3.0.3 on my second eide hard drive. Initially I put
lilo on a floppy and it was working fine. Today I decided to reinstall
lilo on my first hard drive (master). When rebooted it could not start
windows 95. The following list tells what I did to recover and what did
not work in order.
1. boot dos from floppy
   fdisk /mbr did not work
   sys c: gave invalid media type error.
   using fdisk I viewed the partition tabel and the system was UNKNOWN

2. boot with lilo floppy to linux
   mount -t msdos /dev/hda /mnt
   ls /mnt
   gave invalid file type error.

3. I tried lilo -u but no luck.
   same problems as above: both linux and dos could not read the c drive

4. I copied boot.0300 to /dev/hda
   now linux could see some files but with weird names in my c drive

5. I rebooted without floppy and I got invalid system disk error.

Now the situation is linux can see some files with weird names and dos
gives invalid media type error.

Any help will be appreciated.
