I chose Caldera OpenLinux Workstation - loaded with all the dev features. I selected the partition and said 'format' and then the boot loader option(GRUB/Lizard, not good old LILO) asked if it could write into the MBR(Master Boot Record) and I checked the option true and the OS boot options as Linux and pre-existing Windows. Now the insane part, after the install it went into Linux and then when I rebooted, and tried to go into Windows it threw me into a shell - command prompt asking me to give the location of command.com ; after some headache I lead it to command.com using the Windows startup diskette. Then what do I see? The drive C: has been renamed D: and vice-versa. I just could not start win.exe from D: (Himem.sys present, but it was blind to keep saying it does not exist) - using fdisk I set the present D:(earlier C: dont confuse . . .) as active but to no avail. Then getting bugged of it all I reinstalled Windows 98 from my HP Pavilion System Recovery CD with a do not format and the installation occurred in D:(earlier C: remember ! so after that I had 2 sets of Windows folder ) and the contents were preserved; now I have to do something about the registry - will my previous programs work what do you think? Though they are not working now. Lets see - hope I dont goof up again. But I am puzzled about how the renaming occurred - any ideas ???
