Ubuntu 9.10

  I have been trying to install Ubuntu 9.i into a partition. I get about 83% through the process, and then when I choose the partition I get the error message"No root file is defined. Please correct this from the partitioning menu." The partition is a FAT 32 or NTFS (I've tried them both).
My friend tells me I probably need an EXT2 partition. If so, how do I convert the previous file types to an EXT2 partition?

Lots of partition problems with 9.10.  It's supposed to install automatically and convert existing partition you choose to EXT3.  I installed to two different computers to it's own hard drive, one installed with no issues, the other refused to see drive and format to EXT3.  9.04 installed without issues and then upgraded to 9.10 with no issues.  Probably best to run Live CD and never install.

I have a friend who managed to get the Ubuntu installed into the partition. The hard drive is partitioned with Windows XP, Vista, a blank partition and Ubuntu. It comes up automatically to Windows XP, but no way to access the other two. I've read something about a Grub booter or something like it.
   Can you enlighten me on this?

Hello,

GNU Grub is a boot loader like LILO. Basically a boot loader is the stuff that you use to select the OS you would like to boot up. The options are shown in a list.

It is useful when you have a multi-boot system.
