Setup is as follows:
Asus A7V motherboard with AMD 900 mhz Thunderbird 512mb ram
Three hard drives-first two on built in Promise ATA 100 controller-the third on built in ATA 66 controller.All drives partitoned into two parts.
First drive first partition (C)Windows 98SE
Second drive " " Linux Mandrake 7.2 Complete
Third Drive " " BeOS
NEW TO LINUX! My Linux drive is /dev/hdf.Did Expert install-installed full packages.During Bootloader configuration there was a choice as to where to load it MBR or another-don't remember exact one-I choose MBR.I have System Commander Personal Edition installed on the Windows drive -is able to boot Windows & BeOS fine but gets an error when trying to boot Linux. Linux will boot fine if I unhook the other disks-will not boot with System Commander.Shouldn't there be an option for either LILO or Grub when installing the bootloader? This setup is using Grub which I was told wouldn't work with System Commander.At boot when the choices pop up if I hit "e" to look at one of the items then select "e" again I get a GRUB prompt. I did have to go in and edit the boot line to add parameters for the ATA 100 controller via instructions from Mandrake.
Do I need to atart over again to get this to boot thru System Commander? Is there something during Installation>bootloader installation that I should be doing to get LILO instead of GRUB and to work with System Commander where should the boot record be stored:MBR,hdf,/boot? Is there a way to fix this with the presnt install? Any help will be appreciated-thank's-Dave

Just my opinion...
 

This is just my opinion.. but you are trying to do too much. I have gotten Linux working with System commander and WinNT, and FreeBSD, and SCO and Win98 all on the same machine.. but it really wasn't worth the effort.

With Windows, BeOS, and Linux all on the same machine.. and you trying to use them all.. how will you learn any one of them very well?

In any event, if you insist on overloading your box.. the documentation that comes with System Commander has everything you need to install all of these together and get them working.

One option you might want to consider while you are just "trying out" Linux.... boot to a floppy. THen you can just insert the floppy and choose the System Commander option to boot to the floppy. Ta-dah!
