Re: lost Win98 after installing RH7 Linux

["Darren O'Connor" <odarren yahoo com>]

I had a similar problem when I ran LILO, where I could no longer boot
Windows95.  I played with all the configuration settings to no avail,
then found the following in an FAQ.  Since I couldn't run DOS, I
followed the instructions to copy the .0301 (or similar) file back to
the master boot record of /dev/hda, found in the second paragraph
below.  I was then able to use a dual boot option of Win95, as outlined
in "Learning Red Hat LINUX", but I'm not sure if the same will work in
Win98.  

Good luck,
-D

4.7 How do I remove LILO so my system boots DOS again?

   Using DOS (MS-DOS 5.0 or later, or OS/2), type FDISK /MBR (which is
   not documented). This will restore a standard MS-DOS Master Boot
   Record. If you have DR-DOS 6.0, go into FDISK in the normal way and
   then select the `Re-write Master Boot Record' option.
   
   If you don't have MS-DOS or DR-DOS, you need to have the boot secto
   that LILO saved when you first installed it. You did keep that file
   didn't you? It's probably called boot.0301 or some such. Type
   dd if=boot.0301 of=/dev/hda bs=445 count=1

   (or /dev/sda if you're using a SCSI disk). This may also wipe out y
   partition table, so beware! If you're desperate, you could use
   dd if=/dev/zero of=/dev/hda bs=512 count=1

   This will erase your partition table and boot sector completely: yo
   can then reformat the disk using your favorite software. But this w
   render the contents of your disk inaccessible--you'll lose it all
   unless you're an expert.
   
   Note that the DOS MBR boots whichever (single!) partition is flagge
   as `active'. You may need to use fdisk to set and clear the active
   flags on partitions appropriately.
