    I always use the manual installation method. You have complete control that way.

    As a side note, just before final install, click on advanced options and uncheck the box for installing GRUB. Otherwise, you will overwrite your existing GRUB. Sometimes that is not a problem and the new GRUB will find your other operating systems and install them. But I have had it to create problems before. I prefer to keep the existing GRUB and add the new installation to the existing menu.lst file.
    Break it, fix it, learn something.

    so you mean to say that you cannot manually specify it to format just the unallocated space as ext3 logical partition at mountpoint '/'?

    I have Win XP multi-booted with Ubuntu 8.04.1, Ubuntu 8.10, and Linux Mint 6. All three Linux OS's share the same SWAP.

    Just do not reformat the SWAP or you'll end up with a UUID problem. But even if you do end up with a UUID problem it's fast and simple to fix! (You'll know you have a UUID problem if Usplash quits and is replaced by a long line of boot-text!)
    Why in the world do you have the same distro installed three times? I just hope that, at least, you have a shared home partition XD

    The problems with UUID are easily fix by just using the device name instead.

    Now I have 4 options:
    • Guided - resize SCSI3 (0,0,0), partition #7 (sda) and use free space
      • This appears to resize my largest partition, then use the space to install Ubuntu. It still leaves the 20GB free!
    • Guided - use entire disk
      • No thanks!
    • Guided - use the largest continous free space
      • This is the option I want. However, the "After" shot shows 100% of the HDD allocated to 8.10, hmm.
    • Manual
      • Again, great, except the "After" shows 100% HDD allocated to 8.10

    I'm too scared to go beyond this point with either options 3 or 4, because first time I installed Ubuntu I managed to delete all my partitions by doing just one click too many!
    Just use Manual (clicking next doesn't do anything, it's just take you to the partitioner tool), make a space wherever you want and format it. I would recommend you to use a shared home folder, but if you don't want to mess like that, just make space for 8.10 as I said and set it's mount point as "/", next, next, finish.

    Advantages of separated home partition:

    • No more pain, you won't have to worry about losing data when you install a new version of Ubuntu ever again, or any other distro.
    • You won't lose your personal settings

    Ah thanks, so I'm just being over cautious (stupid) Showing the "After" with 100% of HDD allocated to 8.10 is misleading.

    8.04's home directory is stored on the largest partition, as will 8.10's.
