Does grub2 support booting off of encrypted partitions? I'd like to have an encrypted linux system, but only have space for one partition or logical group in my mbr. Or can I include that one /boot partition in the lvm group.
View 8 RepliesI installed Fedora 15, which was my first real departure from Debian based Linux OSs. I absolutely love the new Gnome 3, and was able to configure F15 to work as I wanted it to. On rebooting I realized that there was no boot loader screen, that F15 just booted and didn't give me a choice as to which OS I wanted to use. Eventually I was able to configure grub to let me see the boot loader and added my old boot loader as a choice. This worked well, maybe not a perfect solution, but it worked. This weekend I installed LMDE (Linux Mint Debian Edition) to another HDD. LMDE uses grub2 and after the install F15 was not recognized.
Two questions: Is there a way for grub2 to see F15? or Can F15 be installed using grub2? I really don't mind re-installing from scratch.

I have a dual boot Win7/Fedora 12 laptop. I set the region to 1 on the windows side.
I just updated a system to Fedora 12. It has the same partition setup as the previous Fedora 11, but now when booting it pauses with a padlock icon next to a text entry box.I'm assuming it's trying to get my password to mount the encrypted partitions I have on the drive.
However, most of the time when I'm using that computer, I don't want those partitions mounted, and I would prefer to do a luksOpen/mount manually during those times I need the data thereon. Is there a way to get plymouth to ignore those encrypted partitions while it's booting, so that bootup doesn't pause for user input? I have an empty /etc/crypttab and the partitions in question are not in /etc/fstab.
For anyone who's looking at this, pass "rd_NO_LUKS" on the command line to disable the initrd from looking for encrypted partitions to try to mount.
I'm trying to boot my Fedora 12 partition, but am failing miserably, when I try to boot Fedora 12 I get "ERROR: NOT AN ASSIGNMENT"

Note that I tried this using the entry that is currently commented out and I had the same result. Does anyone know what is wrong? The entry that is currently uncommented came directly from the grub entry created by fedora itself (before I installed ubuntu).
I had to reinstall Windows, which has obviously overwritten my lovely Ubuntu Natty

I've installed a Squeeze-based distro - Crunchbang - with an encrypted root partition (no LVM), and it won't boot.
Here's what I get: Loading initial ramdisk. Loading, Gave up waiting for root device ALERT! /dev/mapper/hda5_crypt does not exist. Dropping to a shell!
Here's my partition table:
hda1 - Windows (Truecrypted)
hda2 - GRUB2
hda5 - /
hda6 - unused swap
[Code]...
What should I look for? Where do I go from the initramfs shell? Do I chroot? What then? This might be a Crunchbang issue (although others blame LVM which I didn't use, and it's the original Debian installer after all), but there's gotta be a reason it doesn't boot
I've created some encrypted partitions using Disk Utility, and would like them to be automatically mounted when Ubuntu starts up. Is there a guide to this anywhere?
I've gathered that it involves /etc/crypttab and possibly /etc/init.d/cryptdisks, but haven't had much success so far.
Ideally, some of the partitions would mount early in the boot process, while some of them can mount after I've logged in.
I just installed CentOS 5.4 (x86_64) and I encrypted my /home /var /tmp and /mnt/Storage partitions, along with my swap partition. My only complaint is that when I boot, I have to enter my password 4 times, and I did not pick a short password. The password is the same for all 4 partitions. Is there anyway I can set things up so I can just type my password once? Once I get everything set up, I won't be booting that often, but right now it is a PIA.
View 2 Replies View RelatedThis is my specific solution to my specific problem. After updating to Squeeze from my prior Lenny distro (amd64 with whole disk encrytion using LVM2, dm-crypt, LUKS) everything went well - at first. I was duped like so many, thinking that all was well and I could remove the legacy-grub (aka: Grub1) and just use grub-pc (aka: Grub2). As soon as I removed the legacy-grub and rebooted my laptop, I was confronted with:
GRUB Loading stage1.5 GRUB loading, please wait..Error 15 At this point I wasn't sure if it was a Grub problem or a deeper encryption problem - especially after reading that some people had missing packages in Squeeze (lvm2, dm-setup, initramfs-tools, etc.)
Okay, the solution for me.
1. download and burn to disk: debian-live-6.0.0-amd64-rescue.iso[URL]..
2. scroll to and press enter/return on: text rescue
3. choose a root directory - for example: /dev/blah/root (I wrote down the list of possible /dev/.... for reference - this helped me remember where and what I had partitioned in Lenny)
4. choose: Execute a shell in /dev/blah/root
5. once in the shell, I discovered I needed to mount a few of those partitions that I had written down in order to get access to grub-probe, update-grub, grub-install, etc. You may not have to if your partitions are minimal. I you need to use other partitions, type (for example):

I have installed debian 6 on two of my laptops. During installation I chose to encrypt my partitions (swap, root and home). Now I find it annoying that during boot up I'm asked for password, for each of these partions seperately. I have given same password for all three of them. How can I make the system ask for the password only once. I know it can be done because on fedora it was like that before.

View 2 Replies View RelatedI have implemented a web application on Linux that I want to deploy and sell to customers. I want to sell ready systems including the hardware. The application is written in PHP/MySQL. What I am searching to achieve is :
1) Find a way so that filesystem and partitions to be encrypted but without the need to insert some code when rebooting. So that if someone gets out the hard disks and attach to another system, cannot have any access to my files or settings. And of course when rebooting (e.g. after a power failure) encryption to be applied automatically.
2) I know that there are ways to bypass root password on a Linux system. Can all these ways be unassigned ? I want the only way to have access to system, to be by using the root password and nothing else.
I have thought of using a virtual server instead of a physical one (like deploying a virtualbox server) but still would like this to be the most secure possible including not only remote but also local access to system.
Unitl yesterday I have a pc with ubuntu server and desktop. Server I installed first. Desktop later. But I want to remove that server and use the space for other stuff..I mess with Disk Utilities and gParted and remove the ubuntu server partition. But now my grub2 stops working. How can I restore grub2 on the desktop partition and use the unallocated space for desktop without loosing any of my stuff?

I have just upgraded from Lenny to Squeeze, and followed the D-I recommendation to upgrade to Grub2. However, the server will no longer boot - giving a 'missing operating system' error, so it's not getting very far in the boot loader process. I have read, in various location that Grub2 supports GPT, but my efforts to fix the situation have met with little success.
I have managed to boot the system using SuperGrub2 (recovery live cd) and can start up successfully from there. However, when I try to fix the grub installation using the Debian wiki recommendation, I'm met with:
<host>:/# grub-install /dev/sda
/usr/sbin/grub-setup: warn: This GPT partition label has no BIOS Boot Partition; embedding won't be possible!.

The attached disk is 4.5TB of RAID 5 disk behind an Adaptec 5405 if that's useful.
I upgraded from 9.10 to 10.04 (no fresh install, an upgrade). During the upgrade, the installer asked me for the harddisks and partitions to include. I gave him the following ones:
Harddisk 1
1. Windows XP
2. Windows 2000
Harddisk 2
3. Ubuntu 10.04
After the installation was complete, I could only start Ubuntu. Both Windows versions just showed a flashing cursor at the left upper top screen. No HDD activity! How can I get WinXP and Win2000 selectable within grub2?
I updated Grub2 and now I cannot boot my Vista or Windows 7. I am running Ubuntu 10.04. I updated because Grub2 was not updating to the newer kernels that were being installed. Now the new kernel is showing in the boot menu, boots fine into Ubuntu, but my Windows installs won't boot. Current installed version is grub-install (GNU GRUB 1.98-1ubuntu6).

My laptop running on ubuntu has been having some issues and it's giving error reports on logging in. Because I want to retrieve my files above all else, I installed ubuntu to a usb-stick and booted it directly from there. I can asses /media/myharddrive/home and there's a folder called lennard, which is the user account on my laptop. I can't open it however, because I don't have the necessary permissions. I'm afraid I encrypted it with an option that was standard to ubuntu. I have a 23-digit code right in front of me but I'm not asked to enter it so I don't know what to do with it right now.
View 1 Replies View Related[URL](where loading into Windows corrupts the MBR). None of the solutions in the bug thread work for me, however--I'm on a Dell system (so it's not HP tools) and I'm not running PC Angel or any similar service (I checked). I assume it is related to the Dell recovery partition, though my old laptop from Dell didn't have this problem even though it also had a recovery partition.
However, before I had partitioned and set up Ubuntu on my new laptop, I installed Wubi (for transferring over the files from my old laptop because I didn't have time to do a full install and deal with problems like this one). Wubi worked fine using the Windows Boot Loader. I understand that WBL isn't capable of loading Linux on its own, which is why I was wondering if it was possible to have GRUB installed on a separate boot partition (not the MBR) and loaded from Windows Boot Loader. All of the information I could find on it didn't work with Windows 7--but again, I know Wubi was capable of doing it. how to set this configuration up?
Small issue with grub 2. I installed fedora on a usb drive and i'm trying to get it to boot from grub 2. I did update-grub and it found the kernel on /dev/sdd2 but for some reason it is trying to point the kernel file to /boot directory in grub but the kernel is on the usb drive and when i try to set it to look at the usb drive it says file not found.
View 5 Replies View RelatedAround six months ago (last time I reinstalled Ubuntu 9.10), on a whim I decided to check that option to "encrypt [my] home directory". I wanted to see what it was like. Mistake. Since then, I've been unable to figure out how to access the data in my home directory using any method besides booting the computer (usb drive, rip-out-and-stick-it-in-an-enclosure, etc.). Specifically, I find that shell script sitting there that tells you to run it in order to see your files, but it gives some kind of error. I also still have the code Ubuntu tells you to write down in order to decrypt your files.
Fast forward to this past week. I brought in the laptop to Best Buy for repairs to the hinge (the hinge! Ace Hardware could fix this problem! But I wanted to make full use of the service plan.), and I got a phone call a few days later, saying that it hit Best Buy's "No Lemon" policy. They were going to keep my computer and give me in-store credit toward a new one. Of course, I refused to pay ~$70 for them to back up my data for me; what could possibly happen to it when they were fixing a hardware problem?
Anyways, I pleaded with them for my hard drive back, and they said that they could ship the hard drive back to the store so I could get my data off of it. I'm planning on going in there with my external backup hard drive and an external enclosure and doing it myself at the counter (If they charge $70 to back up a Windows partition, how much more will they charge for an encrypted Linux one?). I don't want to embarrass myself by standing around and not being able to get into my own data.
