adding new hard drive and then beta

[ray field]

I want to try out the 12.04 beta so I will be getting a new hard drive. been happy with Lucid but if I'm going to have to move everything over eventually I just want to get used to things, eg if I need to switch to LibreOffice I need to see how it's going to work.

1) can I install 12.04 to the new drive from within Lucid once I've partitioned it?

2) can I rely on Grub to add the new installation on the new hard drive? is there anything I should know/anticipate? what will it look like on bootup? right now there are about twenty kernels, plus XP at the bottom of the list.

1. Why install from within Lucid? You do it in the same way as if you don't have ubuntu. Fire up from the cd and take it from there.

2. Yes, you can rely on grub2 from Lucid to add 12.04 to the menu. But if you plan to keep using grub2 from Lucid, you need to tell 12.04 not to install a bootloader when installing. I am not sure if you can do this because in 11.10 they removed the option not to install a bootloader, you had to select a location to install it. In case it's the same in 12.04 but you do want to keep grub2 from Lucid running the show, you can use the manual install method and tell the bootloader to install on the same 12.04 disk. Keep booting from the Lucid disk and problem solved.
If you use one of the auto methods when installing 12.04 I am not sure where the bootloader will go, whether to sda or sdb.
Depending how you do things, you might need to run update-grub in Lucid so that 12.04 shows up.

If you use grub2 from 12.04 you will notice that the list of all kernels doesn't show up any more. There is only one entry Previous Versions combining all older kernels under it. So the menu looks a bit tidier. In any case, you can remove your old kernels in Lucid and that list will shrink too.

lol Sorry, don't be offended but you made me laugh :D

Assuming you don't use all those kernels go to /boot/ and remove the old kernels you don't want/use/need (you'll need root privileges to remove them). I only keep the current and previous kernel.

Regarding GRUB: if there are OSes or kernels on your machine but not in the grub menu, or there are old OSes or kernels in the menu that you have removed, run

sudo update-grub
and GRUB wil look for new stuff to add and old stuf to remove from the boot menu.

very helpful, Darkod. I really don't much care for installations, they always take longer than I want and something always seems to happen -- I figured if I could install from withing a booted Lucid I could 1) remove the possibility of overwriting 10.04, and 2) continue to use the machine to work on. since I want to see how well all the applications I use on Lucid work on Precise.

I'm indifferent as to which grub I use, though generally speaking I like to assume latest is greatest. I am a little bit worried about sda v. sdb -- are internal drives still master/slave, or will the BIOS allow me to select which drive is recognized first?

no offense taken, Miegiel! I just don't like to futz with anything that MIGHT break.

since I'm asking -- did I see somewhere that 64-bit is the default or something? since I prefer to stay from the bleeding edge, plus I rely on funky things like dosemu which can be touchy, I think I'd rather stay 32-bit -- is that what I'll get with this here ubuntu-12.04-beta1-desktop-i386.iso I downloaded?

Yes, i386 is the 32bit version.

SATA disks have no master/slave settings like IDE although in BIOS you might see the sata ports "grouped" as SATA0 Master, SATA0 Slave, etc.

Usually sda and sdb would be allocated according to discovery on boot, and in general it should be in the order of the sata ports from lowest to highest. But regardless of that, once you have them connected, the reference doesn't change unless you change the ports where the disks are plugged in.

So, for example, you receive the new disk, connect it, boot your Lucid and run fdisk -l. If it shows Lucid as sda and the new disk as sdb, that's what you have got. And it will be easy to tell the disks apart even if they are same size because one is empty. :)

as long as I'm going to play with this beta on a new drive, here's what I'm thinking I would do:

1) copy the /home partition from my Lucid install to the new one

2) use dpkg --get-selections > filename to get the full list of packages I want to reinstall on Precise

3) this one could be really chancey: copy /etc/apt/sources.list from the Lucid side and replace "lucid" with "precise" for all

what are the odds of this resulting in a working system? I guess in a way what I'd be doing is an upgrade-drill to my existing LTS release. comments? am I nuts?

[oldfred]

You need to plan ahead on partitions for new drive. Copying /home is fine. New install will update many settings.

I use dpkg to export list of packages and reimport into new install. But now so much has changed that old list installs a lot of software not required anymore. You can manually edit list to remove OpenOffice, old kernels and others. I found I was still installing python2.5. :(
With 12.04 I will try to run a compare of the default install to my exported list and houseclean down to a reasonable list of only the old apps I really want.

Why copy sources list? You could add if you have one or two you have added to you old system but I would not attempt to copy the entire thing and edit. Any edit error in sources list causes big issues, so whatever you do backup its original first.

Some guides on installing to second drive. Difference in versions are minor as I used the same procedure for every version.

Install to external drive 11.04. Also any second drive.

point well taken. in fact the base installation derives from several versions ago -- Jaunty, maybe even Intrepid as well. which might explain the occasional lag I get, or issues I get that probably relate to bodged multimedia libraries. and the last few times I've run Remastersys -dist to back up the system, the filesize has gotten too big. so, much as I would prefer to just copy everything & switch over -- there are dozens of little things I use every day -- it makes more sense to start anew and install as I need.

last night I put in the new HD and installed the Precise beta, and so far so good, though I haven't done much more than set grub to sdb, reboot to see it worked, and then changed the default Nautilus view to List.

one thing that concerns me about Unity is I use a ton of applications and I've always liked the Applications menu, especially for things whose names I can't remember.

anyway now I'm back in Lucid, and

1) using mc, I copied nearly everything from this /home to the Precise /home. although I specified not to overwrite any existing directories, I went back and copied over .thunderbird and .mozilla and will do a few other things. will be very interested to see what happens when I reboot.

2) also copied the Precise /Documents/OpenOffice to /Documents/LibreOffice, since I gather I can't use OO and LO at the same time, I am hoping various templates and macros will work.

3) copied the Lucid fstab entries that refer to two external hard drives and the Lucid /usr/local/data partition to the Precise fstab (after making a copy of the original Precise fstab)

since I use SSH for a few things, including syncing with my netbook and maintaining a Drupal site, I just copied the contents of the Lucid /etc/ssh into the Precise /etc/ssh. fingers are crossed.

I started with new installs with 9.10 after upgrading every 6 months in place from 6.06. Upgrades always seemed to have some issue so they were not the end all best way.

But I found with clean installs I was doing the same thing over & over. I configured my Laptop to be similar to my Desktop and was doing it all twice. So then I decided to try to do as much as I could from command line, listed history & copied commands into a bash file. After some edits I had a personalized install routine.

I installed fall-back and find it close enough to the old style gnome2. I also so not remember names, believe if using keyboard I should do everything there, or if using mouse should be able to only use mouse. I do not like having to type in a file name to launch a program when using mouse.

I have not tried this yet in 12.04 as I keep trying to learn a bit about Unity. But will install it soon in my test version.

this is very wise & I think is going to be how I do things going forward. by the time Precise goes gold I should be up to speed & will have an install routine ready for the netbook -- which really *needs* something like Unity, since right now too much screen real estate is taken up with menus and launchers.

I think the key to not hating Unity is waiting till it got out of alpha. certainly if Compiz is as thoroughly integrated as it seems to be from my first impression, it should be fine. in fact it is starting to look to me like a sort of inevitable evolution rather than some crazed notion of Shuttleworth's.

thanks to all for the guidance (handholding).

okay, I've been playing around with Precise and doing a little tweaking.

however, though Update Manager has installed another kernel

/boot/vmlinuz-3.2.0-20-generic-pae

it doesn't come up on the grub menu on reboot -- only 3.2.0-19 is there (maybe .17 sometimes as well). I'm pretty sure I set Grub to boot from the first hard disk since it was more important for me to work on the Lucid side. I tried to run update-grub from there, and it seemed to be aware of the kernel on /dev/sdb but didn't seem willing to add 3.2.0-20.

how can I make sure grub updates the grub menu I use all the time, the one on /dev/hda, or am I missing something? searching I came across this from good old Fred:


Grub can be nasty on which MBR it installs. It wants to install to sda or the boot drive. They are updating and it seems to change.

to get grub to remember where to reinstall on updates:
sudo dpkg-reconfigure grub-pc

however when I tried to run this in a terminal, I got


/usr/sbin/dpkg-reconfigure: grub-pc is broken or not fully installed

and when I tried to install grub-pc through synaptic, I got


The following packages were automatically installed and are no longer required:
casper kde-l10n-de libdiscover2 kde-l10n-engb squashfs-tools xresprobe
discover user-setup kde-l10n-zhcn liblzo2-2 discover-data
Use 'apt-get autoremove' to remove them.
The following extra packages will be installed:
grub-gfxpayload-lists grub2-common
The following packages will be REMOVED:
grub remastersys
The following NEW packages will be installed:
grub-gfxpayload-lists grub-pc grub2-common

which seems a little drastic to me, especially since I plan on using remastersys.

As far as master / slave on my machine i have to go into the bios and select which sata drive is to be booted from. Otherwise nothing will happen as far that. It will go back to the pata drive controller and look there.

[ray field]

drive booting is fine, no concern there.

what's baffling me is why my grub menu won't show the latest installed kernel.

here is the result of running update-grub under Precise:

yet the startup grub menu NEVER shows 3.2.0-20-generic-pae, instead it shows vmlinuz-3.2.0-19-generic-pae as the very first & highlighted selection.

[oldfred]

You are showing both grub legacy & grub2. A sudo update-grub only updates one or the other not both. Best to uninstall both and cleaning install the one you want. I suggest keeping grub2.

You can skip the chroot steps but make sure you have Internet working as you need to redown load the grub2 packages.

chroot & grub uninstall & reinstall -drs305
