Ubuntu Installation :: Lost Access To Encrypted Home After Upgrade?

Jul 28, 2011

I just tried reinstalling ubuntu 11.04 from the live disc, installation went well but afterwards I cannot get access to my home directory which is encrypted and I stupidly forgot to note the mount passphrase. is there anything I can do? where would the mount passphrase be stored from the previous installation and is there any chance of recoving it. Home and the root are on the same drive and the installation did not format the drive.

Debian :: Recovering Grub After Windows Installation - Encrypted Partitions And LVM

Nov 4, 2010

I'm running Debian Squeeze AMD64 with full disk encryption and LVM. After reinstalling Windows 7 I lost GRUB from the MBR. I managed to install GRUB after following this guide and using an Ubuntu 10.04 graphical installation disc, but I only get to a GRUB CLI when booting, so I can't actually choose an OS there.

I tried following this guide but I'm stuck after "# Mount the partitions to /mnt/root" and don't know what to do.

Does anyone know how I can fix GRUB so I get to choose between Debian and Windows 7 there?

Debian Installation :: Recover Grub On A Dual Boot Machine With Encrypted LVM

Oct 16, 2015

My laptop setup is:

sda1: W7
sda2: FAT16
sda3: /boot
sda4: encrypted LVM with debian (everything besides /boot)

now I've re-installed W7 so grub was overwritten. I've tried the procedure which worked for me previously:booting with the netinst usb in rescue mode, choosing a root partition to mount, using grub-install to reinstall the grub:

Code: Select allmount /dev/sda3 /boot
grub-install /dev/sda

Now I'm on Jessie (stable), and this time this fails, and I am able to mount only sda3.grub-install doesn't exit so I'm assuming it has been replaced by `grub-installer'. also '/boot' doesnt exist so I created it manually.

Code: Select allmount /dev/sda3 /boot
grub-installer /dev/sda

The latter fails with
Code: Select all/dev/sda/proc not a directory

Ubuntu Installation :: Lost Grub After XP To Win 7 Upgrade

May 29, 2010

I keep finding the same fixes on the web and they are not working. What I have/what I did: I have a dual boot PC. HD0 was XP. HD1 Kubuntu 10.04. I upgraded XP to Win 7. This jacked my Grub up, now all I can load is Win 7. I don't see the Grub menu anymore. I've been trying to reinstall Grub using varoius web pages like: [URL]

They seem to all be telling me the same thing but not working. I boot into a liveCD. I have to sudo apt-get install grub then I can do sudo grub. I follow the instructions:
sudo grub
> root (hd0,0)
> setup (hd0)
I get "Error 17: Cannot mount selected partition".

Now if I'm understanding this right the reason for that is. HD0,0 is my first HD first partition (which is Win 7), and grub doesn't like windows. I tried swapping it out so it reads:
sudo grub
> root (hd1,0)
> setup (hd1)
I then quit and reboot. Win 7 loads. I don't see Grub.I am using 2 separate hard drives?

Ubuntu Installation :: Lost Grub Menu At Start Up?

Jan 24, 2010

Just upgraded to 9.10 on a laptop with dead Vista which I lost when I moved over to UBUNTU some time ago. Never any problems but when fiddling at boot up tonight I accidentally selected to boot up the Vista loader which went into the Vista recovery, and since then the laptop only opens up the Vista Recovery, ie it does not go to the Grub. Any ideas on how I can get to boot UBUNTU again?

Ubuntu :: Lost Password With Encrypted Home Folder?

Feb 6, 2011

I installed 10.10nbr on my wife's eee 901. Now she cannot remember her password. I've tried booting to recovery to use the passwd command, but that does not work. I believe I encrypted the home folder when I installed. Normally if I don't encrypt home, then I enable auto-login.

Debian Installation :: Live System Working With Encrypted Persistence

Oct 28, 2014

I tried a while getting a live system working with encrypted persistence. The command

Code: Select alllive-persistence activate /dev/sdx2

works perfect, but boot time persistence works only for unencrypted storage. 'Cause I can not append the boot-log as file the most important part here:

Code: Select all+ tailpid=123
+ tail -f boot.log
+ cat /proc/cmdline
+ LIVE_BOOT_CMDLINE=BOOT_IMAGE=/live/vmlinuz boot=live noeject keyboard-layouts=de components persistence persistence-encryption=luks,none initrd=/live/initrd.img debug=true
+ Cmdline_old
+ PERSISTENCE=true
+ export PERSISTENCE

[Code] ....

The most confusing line is "Warning: cryptsetup is unavailable" - I took a look into the scripts, it checks if cryptsetup and askpass is executable if not this message. But:

I mounted the hdd-img file local and took a look: all binaries there.

So I tried a lot getting it working on boot time. I tried it with live-tools from testing, from wheezy and last but not least installed and pinned live-tools to unstable. Always the same. askpass isn't executable on boot time before mounting the persistence.

Config is
Code: Select alllb config noauto
    --apt apt
    --bootstrap debootstrap
    --binary-images iso-hybrid
    --distribution testing
    --mirror-bootstrap http://ftp.debian.de/debian/

[Code] .....

(tried with binary-images=hdd, too)

and yes, cryptsetup is inside package-list (otherwise live-persistence from within running machine with crypted partitions would not work). Live tools I used for last run is 4.0.3-1 from unstable, before tried with 4.0.2-1 from testing.

Whats going wrong in boot system?

Ubuntu Installation :: Grub Configuration Lost - Unable To Boot

Jun 13, 2010

I have accidentally started the recovery OS of my netbook, and messed-up grub. I can start the Netbook from a live CD, but I do not manage to restore grub to anything useful. Below the outcome of the Boot Info Script I have found in the forum:

Code:

============================= Boot Info Summary: ==============================
=> Grub 0.97 is installed in the MBR of /dev/sda and looks on the same drive

Ubuntu Installation :: 9.04 - Lost Grub Legacy In Windows Reinstall

Jun 19, 2010

I dual-boot ubuntu 9.04 and windows 7. I recently reinstalled windows, and it wiped grub-legacy off of my MBR. Reinstalling grub shouldn't be tough, right, especially with clear instructions? Anyway, I can't get anywhere with the official instructions here: [URL]. The first issue is that the current live CD has no program "grub" in terminal. I dug up an old live cd, but I couldn't get anything with the directions:

Find where Grub is. If this gives a few different answers then you will need to find the correct one, perhaps by trial-and-error.
find /boot/grub/stage1
That command didn't find anything, nor did some similar commands found on google.

So I'm really at a loss. What should I do?
-Can I install Grub 2 on my MBR? Will that work with 9.04?
-Can I access my 9.04 install, copy files to Windows, and then just format the partition and clean install 10.04?

Ubuntu Installation :: Lost Windows Entry In Grub After Update

Jul 9, 2010

Ubuntu's update manager recently updated the Grub menu.lst file. It let me decide if I wanted to keep my old menu.lst or the new one. After deciding that I was fine with the new one, I found out that I can no longer boot into Windows 7. I had previously edited menu.lst so that Windows would be at the top of the list, however, I didn't notice that this had put it into the automagic update area, and I realize now that I should have just edited what the default number was instead of moving around the entries.

Anyways, I can no longer access my Windows 7 OS via Grub, and I was wondering what sort of fix I can have for this. I've tried running update-grub, but it hasn't fixed the problem. The Windows bootloader is on the first partition of the only hard drive, as far as I can remember.

Ubuntu :: Upgrade To 10.04 - Encrypted Home Directory Access Lost

Nov 7, 2010

Apparently after an upgrade, I lost access to my encrypted home directory. Looks like upgrade scripts changed the scripts that mounted my encrypted home directory. As I don't have my ecryptfs password handy, is there any way to revert the things back as they were? I have liked Ubuntu all the way but after this upgrade-mess-up, I might change my view.

Debian Installation :: Encrypted LVM Install - No Root File System Detected

Jun 1, 2013

I'm a long time user of Debian, but I'm having trouble with my partitioning process. Here is where I currently stand:

I am installing the latest Wheezy build. I am trying to install debian with an encrypted LVM that spans two hard disks.

My partitioning layout is as:

1. /home
2. /root
3. swap
4. /boot

I then added partitions 1, 2 and 3 to a physical volume group. I then took that physical volume group and added it to a logical volume. Then I encrypted the logical volume, leaving the /boot partition untouched. I was under the assumption that the only partition the system needed free to reach the loading of the LVM is the /boot partition, as it holds the files necessary for booting. But when I attempt to finalize the disk, it gives an error stating, "No root file system detected". That would be an issue as it is currently sitting inside the encrypted LV. Am I wrong in including the root partition in the encrypted LV?

What is the best way of having as little of my file system non-encrypted as possible while still allowing a proper boot?

Ubuntu Installation :: Grub Menu Lost After Dual Booting With Natty?

May 16, 2011

i have lucid lnyx installed as my main system and added natty on a seperate drive. after installing, the new grub detected lynx & i was able to boot into each without any problem. after doing some tweaking on natty (changed run level), it didn't boot properly so i reverted to the old config via rescue disk. after rebooting, the old grub menu didn't show & it loaded lynx automatically.

i tried the suggestion from another post changed the hidden menu and updated grub but it didn't detect natty (below).

Ubuntu :: Grub - Lost My Windows Partition - Can't Find Menu.lst In /boot/grub

Nov 1, 2010

I got ubuntu 10.04 lucid lynx along with windows (dual boot) and using Grub. On my computer, I have my C:/ (programs) and D:/ (data). I've never used my D:/ before that day that I've lost my windows partition on my grub menu. I usually use my D:/ with windows.

After "fdisk -l",

I checked in /boot/grub and there is no menu.lst to modify. how I can get back my windows option in my grub menu ?

Debian :: Grub Does Not Work - Encrypted LVM

Jun 3, 2015

I have a problem with my debian install. I 've got a laptop with 3 OS:

First I installed windows.

Then I installed ubuntu 15.04 in an encrypted partition, and another partition with /boot (/dev/sda6) created when I installed Ubuntu.

And, finally I installed Debian 8 in an encrypted LVM (/dev/sda8) with 3 partitions (/, /home and swap), and a /boot (/dev/sda7) partition created when I installed Debian.

Needless to say that both /boot partitions are not encrypted

Previously I had a similar configuration with ubuntu 14.04 and Debian wheezy.

The problem is that I can't start the system by using the Debian grub (/dev/sda7). So Ihave to boot the system using Ubuntu's grub (/dev/sa6). The second part of the problem is that when I boot Debian using /dev/sda6 (ubuntu's grub) , plymouth does not work.

I tried purging grub and reinstalling it again with the ubuntu partition mounted, and it did not work.

I did not have this problem with my previous configuration (with wheezy and xubuntu 14.04) ...
