Why can't I install 10.04 on a system that already has 8.04?
Ubuntu 10.04 is beautiful. I love it. I am dying to install it on my PC, alongside the existing Ubuntu 8.04 (from which I write this message right now).
But... it won't let me! When I reach the partitioning stage (manual!) Ubuntu 10.04 sees my two HDDs as one RAID volume. It doesn't see all the partitions I already have in place in /dev/sda and /dev/sdb. Even Windows 7 doesn't behave like this... (yes, I actually managed to install Windows 7 64-bit in dual-boot configuration with Ubuntu 8.04 on this same system). Note: GParted on Ubuntu 10.04 (live CD) sees the partition intended for Ubuntu 10.04 (/dev/sda4) perfectly, but is unable to format it. Note: I also removed that partition trying to reformat it via GParted once 10.04 LiveCD is loaded. It didn't help. I believe that the problem lies in Ubuntu "deciding for me" that the HDDs should be "seen" as a RAID, hence any partition is seen by GParted (10.04 LiveCD) as "busy" or "locked". Any idea how to solve this problem? |
are you using raid?

Thank you amani. Here are my answers, hoping you can help.

When you run Windows and get into Control Panel -> Administrative Tools -> Computer Management -> Disk Management do the physical disks show up as Basic or Dynamic Volumes?

All Volumes are reported Simple + Basic -- without any exception. |

Also, make sure the hard drives are connected to the Intel Corporation 82801IR/IO/IH (ICH9R/DO/DH) 6 port SATA ports, and not the J Micron ports from your output of lspci. |

Any other ideas? |
use the alternative installer iso - that will give you more options
|
The other option is to use pass options to the kernel at boot-time...
|
The best thing to do is just do an in-place upgrade on an existing system. Just open Update Manager and you probably will see 10.04 in the list of newer releases it gives you.

Thank you all for your insights so far. |
the iso is in the ubuntu site and mirrors

Then, as the CURSES based setup continued, I was prompted with a question: Quote:
Then installation seemed to have proceeded successfully, to completion. I am still unable to boot to it, however, because I explicitly told it not to install GRUB on the MBR (I am still using 8.04's GRUB). I modified 8.04's /boot/grub/menu.lst to include: Code:
title Ubuntu 10.04.1, kernel 2.6.32-24-generic I wonder whether 8.04's GRUB is unable to boot 10.04's /dev/sda4 because it's formatted to ext4. Or perhaps it requires the partition's UUID? Let's find it by typing: Code:
blkid /dev/sda4 |

I honestly don't remember if the grub legacy from 8.04 included support for booting ext4 partitions. Does anyone know this? Quote:
What errors do you get when you try to boot 10.04 from 8.04's grub legacy? |
