Hi,

- Is the grub configuration that is used on the last installed linux? So if I install ubuntu last will the /boot/grub/menu.lst file that is used by the system be there or on the debian partition? If so why is this and should I do something to only have one grub configuration through out all my partitions?



I don't use grub but I can say this from practical experience installing Linux and Windows. The boot manager needs to be installed in the MBR, regardless of what OS you use or which boot manager. I think you said you have Windows installed so it probably put its own boot sector in the MBR but not necessarily so. Also, each bootable Linux partition needs a boot loader such as lilo or presumably grub. Therefore, my guess would be that all your Linux partitions need grub installed because grub actually boots the kernel once the boot manager calls it from the MBR.

This is just a suggestion, but I would look at the mbr package. If you run install-mbr from Debian or another linux partition, it will install its own MBR code which doesn't need grub or lilo but will call the boot loader for the partition you specify at boot. In other words, I have my system set as follows: hda1 is Windows, hda2 is Linux, hda3 is swap and hda4 is an extra FAT32 drive to exchange files between the two OSes. To boot Windows, I just turn on the computer and do nothing because it's already the default active partition. To boot Linux, I press the letter "a" for advanced and the number 2 for the second partition as soon as I hear the second beep but before the actual boot process starts. The reason for pressing the "a" first is because hda2 isn't marked active and Windows and/or the BIOS is limited to only one active partition. Linux doesn't care if it's active or not but it won't boot an inactive partition unless you go into advanced mode. From there, either the standard Windows boot loader takes over or lilo runs, depending on what OS i'm booting.

As always, there are several howto documents on multiboot setups. I suggest you read them, at least two were for grub.

You asked about deleting Ubuntu. I can't help you there but I would just delete the partition. However, with that many distros installed, I would probably set aside another small partition for /home. Otherwise you'll have to backup your /home dir for every distro separately.
