General :: Multiboot / Upgrade From LVM-based Partition
Dec 27, 2010
I currently have FC3 Linux which installed itself on the hard disk using LVM partitioning, so it is basically all one big partition. I would like to try some other distributions and upgrade to something newer, but don't want to lose my current capabilities and data files, and I know nothing or less about LVM. Is it possible (and if so an example would be nice) to install a non-LVM-based distribution on the LVM disk and have multi-boot options? Or do I have to start over new and drop the LVM? My guess is that I should save my /home (data files and .rc files) on a backup device first, then somewhere/somehow create a new partition for installing another distribution.

I plan to partition my hard drive so I can install fluxubuntu, minimal ubuntu with IceWM, ubuntu, and windows. (This thread is not about windows, that is just incidental) I have heard that I should use a partition for each OS, and a seperate partition for data, and that it is more secure that way. (as long as you apply appropriate security measures) I have also read that one should make partitions for system files(files that one does not want people to have writable access, such as the etc directory) My question is, what size should I make the OS partitions for minimal ubuntu with IceWM, FLUXUBUNTU and ubuntu, and are there system files that could be easily shared between them. finally, it seems obvious that all three OS's can share the same data partition, and swap partition.

I'm trying to get a fully encrypted system with several linux partitions.I use one big encrypted (luks) partition which I divide into several smaller with LVM but I still need to set the boot folder on a non-encrypted partition.So my question is : is there a way to have only one boot partition instead of one for each system ?

I have a server running Fedora 6, which I wish to upgrade to Centos 5.4. This will be a lengthy switch over because of all of the apps I need to convert etc. As a precaution, I would like to keep my old Fedora running as multiboot. I have a boot partition, a fedora partition (root), and an empty partition for Centos.
Can I run the Centos installer and direct it to install onto the empty partition (I don't care if it formats it)BUT only add to the boot partition (not reformat it).? I don't want to lose the kernels/images on the boot partition, and from what I've seen most installers wipe out the boot partition prior to adding their own files.

I'm using LVM-based partitioning. I can not mount one partition. Here is some information I can provide.

This incident happened after I try to encrypt this partition and then an error message appears. If not mistaken, it contains an error number (I forget) and a warning which reads that can not remove the LABEL on the devices.

I just did an update on my Debian system and it was very long. I'd like to know now, after the upgrades have already been applied, which packages were upgraded and which were not.

is it possible to use a Windows-based recovery partition on a dual-boot computer to overwrite the Ubuntu partition and remove the GRUB loader? For instance, if you booted up your computer, accessed the hidden recovery partition and used it to reset the computer to it's factory default settings, would that effectively remove the Ubuntu partition and the GRUB loader? Would a completely new installation of Windows overwrite/uninstall Ubuntu and GRUB automatically?

I notice that on DistroWatch, the descriptions include "debian based", "arch based", etc. For the newbie, is there any practical difference between the different bases, or is it a Coke vs Pepsi type question?
Is a distro based on Debian say, easier for a newbie to learn or work with than say one that is FreeBSD based?

I have a RAID 5 array, md0, with three full-disk (non-partitioned) members, sdb, sdc, and sdd. My computer will hang during the AHCI BIOS if AHCI is enabled instead of IDE, if these drives are plugged in. I believe it may be because I'm using the whole disk, and the AHCI BIOS expects an MBR to be on the drive (I don't know why it would care).
Is there a way to convert the array to use members sdb1, sdc1 and sdd1, partitioned MBR with 0xFD RAID partitions?

I am a new user of Ubuntu and I am having problems setting up GRUB to multiboot Windows 7, Windows Vista, and Ubuntu 11.04. Following this guide http://erickoo.wordpress.com/2009/06...-karmic-koala/
I got to the point where I need to save the file called '11_Windows' However, in the terminal after trying to save it. (ctrl + x, yes to the save dialogue, then pressing enter) I come across an error that says ' [ Error writing /ect/grub.d/11_Windows: No such file or directory ]'I have spent about an hour trying to find round about ways to create/ save this file and none of them have worked. If someone could tell me what I am doing wrong or what I need to do, it would be greatly appreciated.

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 have been able to get a few of my desired tools working 100% (dban, gparted, ophcrack, UBCD) but what I would ultimately hope to get working is CloneZilla! I was able to get the Clonezilla user interface to load correctly but when I choose any of the options I encounter an error "ntfs volume version 3.1" repetitively. I have a feeling it is because I am launching the iso wrong in my menu.lst config file for grub. This is what I have.
title CloneZilla
find --set-root /CloneZilla.iso
map --heads=0 --sectors-per-track=0 /CloneZilla.iso (hd32)
map --hook
root (hd32)
chainloader (hd32)
boot

I have an Asus EeePC 901, running Ubuntu 9.10. I'd like to upgrade it to 10.04. I don't want to reinstall, since I have a bunch of scripts and programs all set up.However, when I attempt to upgrade using sudo do-release-upgrade, I get an error asking me to free up another ~600MB on /.
My / is mounted on sda0, which is a 4GB SSD. I do not have 600MB worth of deletable stuff on /.I've emptied my trash, and done apt-get autoremove and apt-get clean.I do have plenty of space in /home, mounted on sda1 (a 16GB SSD).Is there some way I can tell apt-get to use a different download/temp directory?

Does anyone know if the context is related to the current filesystem, or the one defined in root setting grub.conf.

I have 10 GB drive with win98SE taking 2 GB and 9.04 taking 2.3 GB, then the rest is unallocated space. I am trying to use upgrade manager in 9.04 to upgrade to 9.10 (I have 9.10 CD but it fails to install - tried to download it several times. I know upgrade manager solution works in principle, but upgrading to 9.10 says it needs another 1GB of space.
I have used 9.04 live disc to start GParted but there seems no way to resize the 9.04 partition to use the unallocated space - can only resize it down. Making the unallocated space a partition does not seem to help. How can I go from here to make enough space to upgrade to 9.10 and keep Win 98

After upgrading from karmic to lucid yesterday made my RTL 8111 -network card die. It's integrated on Intel D510mo mini-itx board.
dmesg:
Code:
After some googling I found out a lot of forumposts about the same problem from year 2007, but the troubles seem to disappear on the newer versions and seem to be back now? With those posts I managed to get the link up by using ethtool by setting autoneg off and setting speed to be 10mbps and half duplex. Any other speed/duplex combination fails.
One suggestion I found was to install r8168-driver from Realtek instead of the r8169. It didn't help, result was very much the same.
I booted to 9.10 live-cd and there the network worked as intended (100Mbps, I dont have a gigabit switch)
I really wouldn't like to fall back to 9.10, but my file server is not very usable with 10mbps.

I have a Truecrypt-encrypted Windows [system] partition, that I want to be opened and mounted automatically (using a keyfile) when I log into Debian, since it is also encrypted and I don't want to type two passphrases. It think this could be done with LUKS. With TC I probably have to go with the CLI, but haven't figured it out yet. And I can't add a keyfile to the volume using the GUI. In order to mount the volume I have to tick the Mount partition using system encryption (preboot authentication) checkbox, or otherwise I get Incorrect password or no TrueCrypt volume found. And same when I try to add a keyfile.

I am working on a set up, and I like to be able to toggle compiz on and off, or toggle dualscreen on and off. The thing is, I also have conky on my desktop as well as a terminal window embedded in my desktop (that requires compiz). So, when I turn comiz off, or resize my desktop, I want to be able to reposition conky/embedded-terminal and the terminals position is relative to my conky position and the size of my virtual desktop.
I can do this all fine, except that to reposition the terminal I need to kill it then reopen it. But if I kill gnome-terminal it kills ALL gnome-terminals instead of just my embedded one. How can I specifically close my embedded one and leave any others untouched? Lets say that the title of my embedded terminal is "trans777"Also, the trans777 titled gnome-terminal will be killed when compiz is not running.
