boot diskette


Hi I was wondering what the command for creating a bootdisk in linux rescue mode was. I would like to keep my boot partition on hda the way it is. Hdb has my linux installation on it and I would prefer to just boot it with a disk for now. I run linux rescue mode, chroot /mnt/sysimage and then su to root but what do I do from there to make a disk that will boot the os?

yea i think i was trying mkbootdisk /dev/fd0 2.6.11-1.1396_FC4 or sumthing to that effect but I was getting errors about disk space. But it didnt seem to access the floppy at all. But I can mount /dev/fd0 to a folder and use the floppy so I know its fd0. I cant remember the exact command I used the last time I made a boot disk and its been awhile.

Every distribution says, "make a boot diskette!" But that, to me, is lame. A growing number of computers don't even have a diskette drive. But they can all boot from a CD-ROM.

If you cannot get a Linux system to start, then imho the appropriate strategy is to plan to recover using a CD-ROM. Completely reliable, capacity 700MB, very fast. I would simply skip the "make a boot disk" step.

Im using the windows boot loader. When I installed fc4 it said that it must initalize hda in order to use it. Erasing all data. So I installed fc4 on hdb and I just want to make a floppy to boot it. I dont want to alter hda at all bootsector included. So I get to the root prompt using rescue mode but for some reason mkbootdisk isnt working for me.

But what boot loader is being used by fc4? It will either be lilo or grub. The method of making a boot floppy differs between the 2.

Take a known good floppy and format it. Using a shell console or from the command line as root do

fdformat /dev/fd0 (or the number of your floppy drive)

Go into /boot/grub and open menu.lst and check that it is correctly configured relative to your partitions.

Now do grub-install /dev/fd0

If you want to make a boot cd then follow the directions on one of my pages
