Been putting off doing the switch/upgrade because, darn it, my system is stable, runs well and I have it set up just how I want it. But I think it's time to go ahead and do it since I will have to do it eventually one way or the other anyhow.

Questions:

1- Can I still just leave my existing /home partition and install /, swap and be ok?

2- I have a slave drive mounted as /mnt/data. Can I leave that alone as well as I am just using it as a storage cabinet for misc. files.

If I recall my partitions are using ext3 but I am not 100% sure.

Any advice is appreciated, thanks.

Personally, I'd do one of two things;

1. Backup your users directory, in order to save personal settings for Firefox and other apps, then reformat the /home partition to ext4.

2. Rename the current user directory, by adding -old to the name, then when creating your user in the new installation, be sure you have the same UID and GID as the present installation.

If you do the second, you will start with a fresh default desktop, but all your application config directories will be available, still owned by you, in the old user's directory, for easy copying.

There have been many changes between how KDE4 configures things and how KDE3 did them, and keeping the old users directory has caused many to have problems with their new KDE4 user's desktop.

The extra drive should be fine just as is. I have 4 hard drives on this machine, and I use the same fstab as my old installations, only editing the / mounting line to reflect the change of partition.

May I ask for a little further detail on how to accomplish option #2? Do I make a copy of the directory and then rename it? I think I understand the UID and GID, just use the same user name I have been using, correct?

Thanks

You mount the partition that will be the /home partition, and rename the user directory, from the liveCD, before doing the installation, then unmount the partition and proceed with the installation. Format the / partition, don't format the /home partition.

When the installation is done, on the first boot into the installed system you have to select a root password and create a normal user. Choose the same name as you originally had on the old installation, and in the advanced section choose the same UID and GID you had in the past. The active home directory for that user will be the one newly created, but the one with the -old extension will also exist, and be owned by the newly created user too. From there you can copy the .mozilla directory to get your bookmarks and Firefox extensions back, before even opening Firefox. The same for .opera, .purple, .pan, .Skype, or any other .<directory>for any other app that has personal settings. Don't copy the .kde directory.

Copy the .<directories> one at a time, and check to see that no problems are introduced to the new desktop. If a problem occurs, after one of the .<directories> is copied over, delete that .<directory> and proceed to the next.

Trying to install Mini Me but getting an "Unable to mount Live CD" error. Two seprate downloads and two CD's both give same error but both will boot in two of my laptops so I am assuming that means the burns them selves were ok.

Just after it checks for USB mass storage devices is when I get this error.

Any ideas?

Don't assume the burns are correct; be sure. From a terminal, with the disk in the tray;

[prompt]$ md5sum /dev/cdrom        <Enter>

If you have more than one optical drive, be sure you address the correct one; might be /dev/cdrom1 or /dev/cdrom2.

If you get errors, clean the optical drive lenses, then try again. If you still get errors the burn is less than correct, and while it may work with certain hardware, it may not with other hardware. If the burn is correct, then one knows for sure to look elsewhere for the source of the problem.

Like all troubleshooting, one step at a time. Verifying the correctness of the image, and the burn, is the first step.

No errors on the md5sum check. Forgot to mention as well that the 2010 beta Live CD worked fine on the machine I am attempting to install the final version on.

Thanks for any help.

When, exactly, are you getting the unable to mount liveCD error message?

Happens right after it checks for USB Mass Storage Devices. None are connected to that machine.

Is your 2009 installation still working properly? Do you have partitions created yet for the new installation? If you have room, I'd create a new partition for the / partition of the new installation, so you don't get stuck between two half installations and have nothing usable.

What I have in mind is to mount the 2010 .iso image, then copy all the files from it to the current /home partition, or another data partition, depending on what you have available, then writing a grub boot stanza to boot from those files. Running from those file eliminates the need to mount the liveCD from the optical device, which is the current problem. If this can be done, then the installation should be able to proceed.

From the 2009 installation, open a root terminal, and post the output of;

[root@localhost ~]# fdisk -l                <Enter>

Then explain what's on each existing partition.

Ok, on a closer look it seems to actually be throwing the error after looking for a "loop image" seems to check for sda1 through 4 then gives the cannot mount Live CD error.

Is the optical drive a SATA or IDE drive?

Do what I asked for in Reply #9 and post the results.

I want to see your entire partition layout, for all drives present.
