Ubuntu :: Install Customized ISO With DM-Crypt Boot Disk?
Jan 7, 2011
I just bought a new laptop which will be running SSD (Corsair 120GB) as the boot drive and would like to migrate my OS to the new system. One of my requirements is full-disk encryption. I work with proprietary client data and need to encrypt the new drive, its swap partition, everything except for /boot. I've read instructions for doing this from the alternate install CD, but my OS is disturbingly customized (started out as 10.04) and it would take months to rebuild everything. I keep remastersys (-dist) ISOs to ensure I don't have to go through that process, but the ubiquity installer does not appear to have the option of doing disk-level crypt during the installation process. I can boot the ISO into CLI, but don't know how to run the alternate installer from there.

I currently using Ubuntu 9.10 last update formated with on a ext3 format. I have been a very happy ubuntu user for about 1 year. I have a win7 but I really do not see the point in installing it any more (only when I feel like playing a game).
Any my question: Some time ago I read somewhere that it is possible to make a customised boot "disk/DVD" so the programs etc. is intallled/deleted like you what from the beginning. ex. late week one of my harddrives crasched - and therefore I created a new and had to go find everything again. (codecs - program - visulizations and so on) I more or less use the same basic thing everytime for everything to work probably to my liking, but this takes me about a day (more or less) and this time wasted.

I'm trying to have a LUKS encrypted partition mounted at startup and to have GDM ask for my key so it will decrypt. Now I followed [URL] to the letter. Except for now, I have it just mounted into /mnt/cryptohome so I'm not messing with my system. My problem is the one everyone mentions in the comments, ubuntu isn't asking for the LUKS key in the X display, it's asking in the first terminal (Ctrl-Alt-F1). This will not do. I need it to ask to mount my drive before I'm even asked to login, so eventually I can encrypt my /home.

It seems I've run into a bit of a problem. I recently upgraded to the latest kernel 2.6.32-24-generic (x86) but when I reboot into the new kernel and type in my password the system hangs, same when using a keyfile on the root file system.to give an outline of how the disks are setup.3 hard drives
sda1 / = unencrypted
sdb1 /home = encrypted w/ luks
sdc1 /backup = encrypted w/ luks
When i boot to the original kernel 2.6.32-21 I'm able to successfully get into the system.

When I upgraded from FC11 to FC12 of the encrypted raid partitions started to request password on boot (in FC11 not having references to encrypted md1 in fstab and crypttab, was enough for FC11 not to ask for passwords on boot) despite the fact that I removed /etc/crypttab and there is nothing in /etc/fstab relating to encrypted md1 (raid array). I want my machine to boot w/o asking me passwords for encrypted devices, and I will open and mount them myself manually after boot.

I can't believe that I did not write down the password to my encrypted volume. Had not rebooted in a long time so I had not typed it and now that I rebooted I don't remember what is was.
Is there any way to automate the trial of different passwords? I remember the basic structure of what the password was so if somehow I could automate trying passwords from a list I may have a good change to recover my volume.
If/when I do remember the password. Is there a way to change the password on an encrypted volume? I need to make it something I will remember for sure... or write it down somewhere safe..

I've built my ubuntu setup straight from a minimal install, just installing packages to get exactly the system I want, and I was wondering how I could fashion that into an ISO, config files and all. Could I use an ISO remaster program for that task? Or would a simple shell script be easier?

I have the cd image for the install cd of ubuntu 10.04 release candidate. Before I install it, is there anyway to specify which of the default packages I DO NOT want to install (via command line arguments or some other means). There is ALOT of things I DO NOT want, like firefox, "cloud one", "social features", totem, rythmbox, "music store", empathy. I know that the cd allows you to adjust the command arguments for the install command, and something tells me that there should be an argument for specifying which packages to install/not-install or to choose from a list or something to the same effect.

I've done an Ubuntu 10.04 CLI install and installed the packages I wanted for a desktop environment.In a vanilla Ubuntu install, closing the laptop lid gets Ubuntu to go into suspend properly. In my setup, closing the lid triggers nothing. How do I get it to trigger a suspend?

I have a linux server system based on Debian which I'm needing to package up as an installer cd; so that I can distribute it to others in our office/group for them to install. I need to have it as simple as I can as most will be able to run the installer but many won't know too much more than that. Is there a way I can make up/modify an installer of Debian to include my kernel patches/updates and customized software all pre-installed of the installer cd?

1. unzip packages.en.gz and then we update some packages version info and SHA1 value in packages file 2. generate new suse/setup/descr/packages, and zip it to packages.en.gz
3. update SHA1 value of packages.en.gz in content fileThen we try to burn an ISO to install, installation fails at the beginning because of incorrect signature of content.
cd:/content invalid signature
Alt+F3 I see the messages:
loading file:/var/adm/mount/content -> /content

I have 50 identical workstations that are being dropped shipped from the vendor directly to the remote locations. I need to install a identical configuration, including installed packages, scripts and customize configuration onto each of this workstations. I cannot set up a kickstart server to install from remotely because of my organizations security policies. Not to mention that it would be painfully slow. I thought about DD-ing my "Master" build and sending it to the remote sites, but some of the admins are not very Linux savvy. I would really like to build a bootable DVD that would install the cloned Master build from my server to theirs. I was looking for something that would look like Anaconda to the person installing the image. If I could get them through this base install I think it would be easy to document how to change the workstation unique parameters or value. How to accomplished this? BTW, this will be a RHEL 5.3 server install.

I just installed Ubuntu on my laptop (x200s, XPpro with 230 Gb), and created a 30Gb partition therefore. At the end of the install, the screen remained orange for a while, without any disk activity. I forced the laptot to reboot, but Ubntu was no option when the machine restarted. However, my XP partition has been reduced by 30 Gb. Does anybody have an idea about what I should do to either get Ubuntu installed or recover the disk space?

Have a coworker that plays around with computers. He built a dual processor, 64 bit with 64mb of ram on a server board. Do not have the specs at this time. He installed purchased version of Suse 8.0 server. Using KDE. (Don't know why he went this route. He is not setting up a server.) His problem is it will only boot from a CD. He can take out CD and it runs ok. A friend told me that there is a way to check the master boot file, but I do not know how to do it. I am learning trying to learn Unix/Linux programming. I can do some commands in terminal.

I tried installing Ubuntu 10.04 WS on my PC but it did not see any disks to install on. I believe this is because my drives are all configured as RAID. My mobo is an Asus M3A78-EMH HDMI AM2+ socket with an Athlon 2X 5000+ CPU. The chipset is AMD 780G. I have the BIOS configured for RAID drives and I already run Win XP x32 and Win 7 x64 on it. My boot drive is configured as 'RAID READY' and I have 2 RAID 1 disks consisting of pairs of SATA drives.
From what I have researched it seems that with some tuning it should be possible to install Ubuntu 10.04 but I have little Linux experience and don't want to mess up my existing drives. I have installed Linux before a few times and run it but never with RAID. Is anyone aware of an existing disk image that I will be able to install from on my system or would it be possible for someone to create one for me to use?

After buying a new PC, I decided to "reorganize" my former PC as follows:Initially it has been a dual (SATA) disk dual boot PC- one disk for each OS, while XP was fully installed on a single NTFS partition. Using Gparted I shrunk the XP partition, and created some Linux partitions. I've verified that the XP partition (sda1) is bootable. Afterwards, I removed the other (former Linux) disk from the computer. While doing so, I had to temporarily disconnect cables from both drives. Finally, I fresh installed Mint 9 (Ubuntu 10.04 derivative), on my pre-prepared Linux partitions. Installation completed flawlessly, and during the install, I've noticed that GRUB2 has been installed on sda. Rebooted and got "Disk boot failure" error.
I've checked the BIOS and noticed that the (single) drive was not recognized.
I manually tested from the BIOS and located the drive as IDE3. Saving the new configuration (F10) and rebooting- the HD gain is not identified (the CMOS battery is fine- keeps time).
Booting a live CD I can see and access all above partitions.

Downloaded Ubuntu 10.04.1 Desktop AMD64, tried to install it to a cleand HDD using the whole HDD, i.e. gave it permission to use the whole HDD. Installation process appeared to run OK but when it came to the restart it just fired up the message
error: out of disk

I've searched this forum and found numerous references to these error messages but cannot make head nor tail of the diagnostic suggestions. Apart from anything else they suggest strings of command lines which I don't understand and can't enter anyway since they don't correspond to my keyboard layout (if I hit > or ) something completely different appears on the screen). Is there someone here who can provide a step-by-step solution in lay language? Or is there such a thing as a bootable file which can be downloaded and inserted into my CD drive to correct this problem?

I am still using Lucid with a Luks/dm-crypt setup. I picked up an upgrade today that included grub. It gave me a box that had me choose my location to install the upgrade. I chose /boot. When apt did its upgrade thing, I got the following message: Setting up grub-pc (1.98-1ubuntu ... /usr/sbin/grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea.. /usr/sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and its use is discouraged.. Installation finished. No error reported. I looked in /boot/grub and found no menu.lst file.

I scored a Dell poweredge 6300 from a local pawn shop. It has the capability to boot from cd-rom, but apparently not with isolinux, which is what the debian installer cd uses. I was able to boot to UBCD411 (Ultimate Boot CD, which uses syslinux), but didn't see any option to boot to a CD (maybe I'm missing something here?). I tried using the boot floppy from this site. I didn't expect it to work (it's from the Woody era), and it did not. I got a message that says SYSLINUX ver.XXXX CBIOS boot failed. I went to [URL].. and looked for a boot floppy image for Lenny, but apparently it doesn't exist. I did however find the boot floppy image for Etch.
To be honest, even if I did find the Lenny floppy boot image, I'm not sure how to use it to point the system to the installer CD. So, I have two questions:
1) Does anyone know of a boot floppy image for Lenny, or if I could use the Etch boot floppy image?
2) How would one boot from floppy, then point the system to the installer CD?
System info:
(4) Xeon Pentium 2 processors 500 Mhz
(6) UltraSCSI hard drives
(1) SCSI cd-rom drive
(1) SCSI dvd-rom drive
(1) Floppy drive
(1) 10/100 NIC
I'm open to any other suggestions as to how I could install Debian Lenny on this machine.

I successfully booted OpenSuse 11.2 from DVD. But I could not configure my wireless internet connection. YAST said it couldn't configure it because something else was controlling that (Network Manager? something like that)How can I configure this. Related issue. When booting from DVD is there a way to save configuration settings so I don't have to start from scratch the next time I boot from DVD?

I have multi-version Kernels on a Dual Boot WinXP / openSUSE 11,3 box. It's been a LONG time since I needed to boot to Win XP and now that I find that I can't get to it, I can not say for sure what I did to break it. Looking back, I suspect that the method I used for the recent removal of one of the Kernel versions may have been innappropiate. Rather than unchecking in versions/package groups I may have just removed the unwanted kernel in the package list. Not sure. I've tried dinking around with menu.lst and Yast Boot Loader to no success. I get errors depending on what I messed with. Didn't try to reinstall grub until I checked here for help with a fix.
Here's some info:

I have read other posts regarding the installations of different distros on external hard disk, but these did not help..
I want to install fedora 12 on a new external hard disk, so that i can boot from it on any system that supports booting from usb hard disk, and do all my work from the extenal hard disk itself. I want to know the exact procedure to install fedora on extenal hdd, and what do i need to do, so that the grub, (which i will install on the /boot partition of external hdd), get detected by the primary boot loader of mbr..
Or, I just need to boot from external hard disk.. please any one try to make it possible.

I've run the install to hard drive program three times over and each time I get "disk boot failure". I believe I've got Grub to install to the mbr but I am not sure.
System:
Barton 3200+ with 1GB of DDR1
Asus A7V333
High Point hard disk controller
other items
All the hard drives are hooked to the High Point controller. It recognizes all of them that have power hooked up and read/writes to them. Two have 98SE installs, the third is where I'm trying to install Fedora 12 to get away from some problems I'm having with 98SE.
The BIOS is set up to boot from the "SCSI device" which means it's booting from the High Point controller. The High Point lets me set a boot mark, which, when set to the Fedora drive, yields the disk boot failure no matter what I do to it.
