Ubuntu :: Preserving Multiboot Setup On Selective Reinstall?
Sep 14, 2010
I've set up a multiboot with XP, Vista, Windows 7, and Ubuntu 10.04.1, installed in that order in five individual partitions on a single hard drive (fifth is for the Ubuntu swap area). Everything is working well: On boot, the GRUB menu comes up first, with the usual Ubuntu choices and "Windows 7 (loader)". When I select that last option, I'm then given the Windows boot menu that allows "Earlier Version of Windows", "Windows 7", and "Microsoft Windows Vista". They all boot properly, and I don't mind having to use the second menu. I would like to reinstall XP (only) to the same partition it now occupies. I suspect this will mess up my current booting scheme, correct? Is there a way I can prevent this, by saving the GRUB configuration or whatever?

currently my installation is on sda1, while /home is on sdb1. I'd like to wipe sda1 and reinstall Ubuntu 10.04 from scratch.
Can I just run the 10.04 installer, reformat sda1, install 10.04 over it, then follow a guide to remount sdb1 to /home (and chown the new /home)?

I installed Mythbuntu, got some Wine apps up and running, then discovered my Nvidia DualTV MCE won't work with Myth. So I'd like to try a different variant, either the plain vanilla Ubuntu or UbuntuStudio.Can I just use Mythbuntu to create a new partition, move /home/* to it, and then reformat and install over the original Mythbuntu partition? When I reinstall the new version, how do I tell the installation process to use /home on the other partition (without overwriting it) instead of creating a new one from scratch?

Don't know if I should have posted in Ubuntu specific section but since it involves grub2 and a quirk in my bios, I have attempted to multiboot 3 Windows versions and the problem I had was intalling a second Ubuntu. (Don't ask!) I had success multibooting with grub legacy on an older computer but this computer has a tricky mb which won't let me install grub to the second drive on an IDE port. What I mean by this is that since I already had boot files to the older drive in mbr- it won't allow me to install to mbr of the other drive in IDE port even if set first in bios boot order, my old computer allowed me to do so, exept perhaps its because 2 HDD were SCSI... (I have other HDD installed in RAID 0 on the other sata ports supported by mb (fakeraid) but I will use these for video editing as scratch disks later. One other HDD used for data is on the Raid port but not in an array).
I succeeded in installing Ubuntu desktop only after realising that I had to first switch my disk order in bios- otherwise the system would just hang. U. Desktop grub had sucessfully found Win bootloader links to both XP and Vista. I then installed Win 7 and used easy BCD and grub2 boot entry to link back to my Ubuntu Desktop grub 2 menu.
The problem occured when installing Ubuntu Studio ( for which I created a separate /boot partition) and I decided to install grub2 to mbr since it had correctly detected all my OSes! But then it seems it never installed correctly to the mbr. I still had Win 7 BCD bootloader in MBR! I tried to link easy BCD boot entry to the /boot drive but that didn't work and I ended up having to reinstall Win7 because I had overrid the BCD with faulty neogrub mapping entries- which I then removed and kept the orginal neogrub that still points to Ubuntu Desktop grub menu.
I also now realise that because I installed Ubuntu Desktop before I switched the HDD boot order in bios- U. Desktop's grub.cfg sees root of Desktop grub differently than neogrub BCD does root=(hd4,7) vs multiboot kludge (hd3,6) and at first I tried to install grub in the wrong hdds and partitions- I based mapping on neogrub's to find /Boot (hd3,2) and (hd3, 1) which is wrong!
What I am attempting to do now is to chainload grub2 from my Ubuntu studio located in /Boot with what I thought was the right mapping but still no success:
menuentry 'Chainloader' {
insmod chain
set root=(hd4,2)
chainloader +1
}
yielded error: hd 4,2 cannot get C/H/S values press any key to continue, also when in terminal in Ubuntu Desktop in
grub> find /grub/core.img
Error 15: File not found
I will attach Boot_info_script; at this point I am too tired and afraid that I will keep on installing grub to the wrong drive!
Note: I somehow got a problem loading into XP after all these failed attempts and a system 32 file seems to have gotten lost-haven"t attempted to fix yet. Just wondering in passing what happens if I chainloaded into Windows by error- if that could have corrupted it? Right now 3 out of 5 OS are bootable. I hope I can repair it without messing up my mbr again. Another issue is that some devices are on busy IRQs and then suddenly its resolved and my onboard LAN suddenly stops working at times so I don't know if any of this could cause XP to get stuck at loading screen.

I want to upgrade to 10.10, but on the update manager it says it's gonna install 179 new packages that I don't want/neeed (such as open office that takes too much space), so I'm wondering if theres a way to select which one of the new packages I want to install, instead of all of that?

I'm new here, I hope someone can help me get wireless working on my laptop. This is a Toshiba Satellite Pro C650-EZ1533 (Intel Core i3). The Toshiba site says it has "Atheros Wireless networking (802.11b/g/n)", but does not identify the hardware more specifically.
I installed Debian 6.0 from a netinstall disc, the version including nonfree hardware drivers. In the software selection I went with the defaults: only "Desktop environment", "Laptop" and "Basic system".
Now the GUI looks nice and behaves OK, and the audio, video, ethernet, and optical drive are working. However, I don't know how to configure wireless. It's probably my fault. I was installing and uninstalling file managers, trying to find one I would like better than Nautilus. When I went to uninstall one of them, a message in the package manager recommended using a command like "auto remove" or similar (I did not record it exactly). My understanding at the time was that this would only remove things that were installed because of dependencies but were no longer needed. However, *a lot* of things disappeard from the menus.
Now the only thing about networking in the menus is something about setting up a proxy. There should be some sort of network manager, right? Or an icon on the taskbar, maybe? But I don't know what package to install.

I'm new to Linux and Ubuntu, but have started migrating as I like what I see. However, I found a problem with Document Viewer. After downloading and viewing a PDF, when I try to print either the current page or a page range, it insists on printing the full document. I could not find this bug documented anywhere. I'm using Ubuntu 9.10 with the latest fixes etc.

configure which dns the system will consult depending on which user iniciated the request.My goal would be, if user "peter" is logged in and has opened the browser, that requests for name solves from that user goes to certain/s dns server/s. And if user "anne" is logged and request name resolution, that request should be done to another dns server.To say it briefly, the idea would be configure selective dns server use depending on system users.

So I was messing around trying to uninstall Nibbles and reinstall since I have an issue starting that game and something happened and removed the submenu under Games called "Logic", which had another whole list of games.
Is it possible to reinstall the games package or reinstall the update?I'm thinking more of the lines of a system restore or something so back 2 days from today.

Using "List View" in Nautilus (Ubuntu 9.10), is there a way to preserve the column width? If I manually change the column width and click into another folder, the width automatically reverts to the old width when I return.

I'm using two NTFS formatted partitions. One is internal and holds all my data. The other is on an external hard disk and is where I back up all my data to. What I'd like to do is copy all my files from the data partition to the backup partition and preserve all the windows' timestamps (including the file creation dates).How hard can this be? Well it appears that in the case of Ubuntu the answer is very hard indeed.I'm aware that Linux does not support the concept of a file creation date natively. However, according to the ntfs-3g website, all of the windows' timestamps (including the creation date) are mapped on to the system.ntfs_times extended attribute (link). So if you preserve the extended attributes when making a copy then, in theory at least, the timestamps should also be preserved.
I read on another forum that a file's timestamps will be listed (albeit in an unreadable hex format) if you run the following command:getfattr -h -e hex -n system.ntfs_times <filename>Unfortunately however, I just cannot get it to work. With every file I've tried I simply get a message saying "no such attribute".

I am switching to Ubuntu soon for security purposes. I have 3 hard drives, one with my OS, one with nothing, and one with all my junk. I was wondering if there is anyway that I can only reformat and install Ubuntu onto the drive with windows, reformat the empty drive, and then transfer files from my junk drive onto the empty drive, and then format the junk drive and move all of the files back onto the junk drive? Or is the junk drive accessible from Ubuntu and not worth trying to switch formats on?

I am going through the motions of migrating from Rhythmbox to Banshee so that I can field questions about the process as Banshee takes over for Rhythmbox in Ubuntu. I have solved a silly issue about importing playlists (they must be imported from /home/username/ or you must alter the paths in each entry). But there is another issue which I am at a loss to explain.
My playlists are like mixed tapes. They are in a specific order. When I import a playlist into Banshee that order is not preserved. I have checked the files and they are definitely ordered and numbered in the playlists just as they are in Rhythmbox, but Banshee refuses to import them with the order respected regardless of the smallness of the list.
What's going on and how can I correct this?
I'd rather not have to reconstruct all of these playlists.

I could understand the idea of security "if I haven't touched the file in 9 days, and the timestamp was changed, I know someone was in my system". But, is there any other purpose for preserving timestamps?

I prefer to do a clean install of each new version of Ubuntu.I do have a separate /home partition which I preserve during each new install. I also have many additional packages installed.My question is:How do I preserve the list of installed additional software so that I may readily reinstall all of it after each upgrade?

I disliked LXDE's pcmanfm so much that I've switched over to feh and idesk but for the life of me I can't get feh's wallpaper setting to stay between sessions. Typing 'feh --bg-scale /usr/share/lxde/wallpapers/lxde_blue.jpg' immediately gives me what I want, but next login it's gone again. I know I have to put an entry in ~/home/pargoo/.config/openbox/autostart.sh but nothing works. So far I've tried:
eval `cat $HOME/.fehbg` &
eval `cat $HOME/pargoo/.fehbg` &
eval `cat ~/.fehbg` &
[Code].....

My samba-shares are mounted in fstab. Everything works fine except for one small issue: when copying files from the local PC to the share the files are copied but the timestamps and permissions of the files are not. Instead a message "operation not permitted" appears. 'root' on the client can copy files WITH timestamp etc, a normal user cannot.
Below the line in fstab on the client and smb.conf on the server.

I'm going to move from Linux Mint (Debian Edition) to Debian on my Laptop (3 user). The current setup is LMDE-Cinnamon, with 4 partitions; /, swap, home and data. All the important data lives in data while home is used for preferences only.
Am I right in thinking that preserving the data partition is as simple as not formatting it during the installation?
And what about home? Obviously this now contains a lot of irrelevant stuff (Cinnamon settings for example) and many programs will be in different versions...
- Just keep it (after all the irrelevant stuff should not do anything bad?)? And if so how do I tell the installer to do this?
- Format and restore the relevant preferences manually from the backup?
- Format and have everybody set up their preferences as needed?
