I have to operating systems installed, Ubuntu 10.10 and Windows 7, working perfectly. I also have a partition, currently empty, to be shared between both OS, but I would like that partition to be encrypted.
View 2 RepliesI would like to dual boot Ubuntu and Windows 7. I have Ubuntu 9.10 Live CD and Windows 7 Pro Live CD. Ubuntu is installed but Windows 7 isn`t. I have gparted installed. I found the following directions within Ubuntu documentation.
Master Boot Record backup and re-replacement
Back-up the existing MBR, install Windows, replace your backup overwriting the Windows boot code:
Create an NTFS partition for windows (using fdisk, GPartEd or whatever tool you are familiar with)
Backup the MBR e.g. dd if=/dev/sda of=/mbr.bin bs=446 count=1
Install windows
Boot into a LiveCD
Mount your root partition in the LiveCD
Restore the MBR e.g. dd if=/media/sda/mbr.bin of=/dev/sda bs=446 count=1
Restart and Ubuntu will boot
Setup grub to boot windows
I don't want to backup the MBR and restore as listed. I would rather use the Ubuntu Live CD to reinstall the GRUB.
How do I overwrite the MBR?
Do I use gparted and change the partition?
Do I create an NTFS partition as listed above?
Or what do I need to otherwise do to boot the Windows 7 Live CD so that it will install?
Regarding the installation of ubuntu 10.0.4 on my HP pavilion DV5000 laptop.
I previously installed windows 7 in my laptop and i would like to have ubuntu and windows 7 in dual boot. in order to do that i need to free up some space to be able to install to create partitions for ubuntu and the swap even if I have 30GB of unused space.
When i launch the live cD and i reach the step 4 ubuntu is actually recognising three operating systems installed:
- windows 7 (loader) under dev/sda1 (92,86GB) NTFS
- windows NT/2000/XP (which is corresponding to my "HP recovery" partition) under dev/sda2 en FAT32 (6,2GB)
- windows XP embedded (I don't unerstand what it is) under dev/sda3 NTFS (1,1GB)
when I go to the step 6 to modify the size of sda1 to free up some space, i don't have the possibility to change it, i can read "unknown" under the used space collumn.
I also tried to resize this partition using gparted but unfortunately i had the same problem, when i select it all the options to modify it are greyed out and i can notice a key near the hard drive logo (is it locked ?).
While setting up my laptop on a new hard drive (a bad mobo caused writes which pretty much rendered teh old hdd unusable) I was asked if I wanted to encrypt my home partition.
I've been wanting this for several years - even going as far as trying to get a copy of CheckPoint. That's waht my organization uses on all Wintendo laptops and is required.
In any case, I said "yes" and am happily using my laptop with an encrypted home partition. I'm assuming based on this - [URL] - that it is using EncryptFS as the scheme.
if I were to misplace my laptop, how easy would it be for a forensics team to retrieve my data. Let's assume I have a fairly strong passphrase, such as BisZumBitterenEnd3. [URL]
I had some major problems after the recent Ubuntu upgrade and had to boot from a live cd. I have a separate /home partition, but it was encrypted using the default install encryption in the 9.10 install cd. How can I get to my files so I can back them up?
I have tried this but it did not work: http://ubuntuforums.org/showthread.php?t=1337693
I know it is possible to move the ubuntu home directory but what is the best way to move it safely to an NTFS partition that already has valuable data in?
View 8 Replies View RelatedI'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.
View 9 Replies View RelatedI have recently recovered from an HDD failure on my Drobo. One of the disks died and corrupted the entire array (which is not supposed to happen). I have since managed to copy the data off onto smaller disks and after replacing the failed drive, have copied everything back.
Now that im up and running again, i was wondering how this situation would play out on encrypted disks, or in the case of a drobo a large encrypted partition (as you cannot encrypt the entire array).
Would i still be able to recover the data if i were to encrypt it? It is a 4.2TB array, and i assume that I would need to copy the data in its entirety to recover it, so using multiple smaller disks would be out of the question right?
What are the steps I must take to move my existing home folder to a separate, encrypted partition? Can I create this partition without damaging my current partition? Where is a trusted location to download App Armor profiles? What else can I do to harden the security of Ubuntu?
View 1 Replies View RelatedI have Windows 7 on my laptop and am attempting to install Ubuntu 11.04 from CD.I boot from the disk drive, follow the prompts and eventually get to the screen where I can set how much space I want to give to the Ubuntu partition vs the Windows partition. My hard disk is 250GB, so I reduce the Windows one to 100GB (currently has 80GB of files on it) and set the Ubuntu one to 130GB (the other 20GB is split between the two hidden Windows 7 partitions).
I then click to continue and the progress bar for the install starts up but doesn't move, it just sits at 0%. I realised that the dialogue box underneath the progress bar can still be expanded and asks me to test using -n and -s, but when I type either of these into the box and hit return, nothing happens. I have checked my download of the .iso I used using WinMD5Sum and the hash matches up. I have already tried installing from USB but this threw an error, hence using CD.

Hello everI'm really confused by the ways an encrypted partition get mounted.It just mounts the partition without asking for the passphrase used to create it. I can list the files in /mnt/sda2, create a new file test.txt, but have no access to the files written to the "real encrypted partition".Then I can see/change the content of the encrypted partition but without being able to see/change the file test.txt created previously with the normal mount command.
The reason I'm asking is that I'm having my custom Debian to automount every partition available on the system at boot time. Is there any way/command to tell if a particular partition is encrypted (by cryptsetup) or not? So that I can mount it the right way and not make the users confused (or even harm the encrypted data).
Anyone had any experience with unlocking a LUKS encrypted root partition via ssh? It is ok to leave /boot unencrypted.
There are a few pages from google with the debians variants, archived by putting dropbear into initrd.
I like to do that with my fedora/centos remote servers, but struggle to find any resources specific to it. Anyone has any suggestions and thoughts as to what might be a suitable way forward?
I need a FREE solution that can image an entire Luks system encrypted volume and the rest of the used HDD, the MBR and /boot partition. Note: MBR and /boot are not encrypted. Note 2: I want to be able to restore entire drive from image with only a couple of steps. Note 3: Destination HDD space is a factor. Image file must be compressed and the image file must be around 40 to 50 GB or less. The smaller the image the better.
I have used clonezilla live cd before but not for encrypted volumes. I know you can install it in Linux. But, I don't know how to configure it after installation. I would be very happy if someone could tell me how to configure clonezilla in Fedora. How to guides are also welcome. I have one more question. If I image the encrypted volumes and all the stuff I mentioned above while logged in to Fedora, and I restore the drive from the image, will the recovered drive still be encrypted?
I installed Ubuntu 10.10 64 on my laptop with the entire 500gb setup as encrypted LVM. This has worked well for several months with no problems. During this time i have been backing up the data to an external usb drive (1tb) on a regular basis. The usb drive was not encrypted. So, I thought it would be a good idea to encrypt the backup drive too. I wiped out the backup drive and set it up as one large encrypted lvm and mbr. This seemed to work fine but immediately afterwards I decided to erase that and set it up as encrypted lvm guid instead of mbr. I couldn't delete it while logged into my desktop so i decided to do it from a bootable gparted usb stick. In gparted i erased the 1TB backup drive once again and planned on setting it up the way I wanted once I was logged back into my ubuntu desktop. Now I cant boot into my desktop with the following errors:
cryptsetup: evms_activate is not available b0d) does not begin with /dev/mapper/
Then after waiting for a few minutes I get an error followed by (initramfs)
When booting from a live version of ubuntu the 250MB boot patition is recognized and 500 partion is there but it is labeled as empty/unused.
Also, I did choose to use the exact same passphrase as what is used on the main bootable drive when I set up the encrypted partition on the external 1TB drive.
I've just started using ubuntu one. However, some of the files I store on there are sensitive so I encrypt them using seahorse. Right click, encrypt etc etc. My question is, is there a way to automatically get the encrypt process to delete the un-encrypted file when it makes the new encrypted copy?

I want to dual boot with windows 7. How would I go about making a partition etc.,. for windows? I know how to dual boot other OS's off of windows but not linux. I just want to dual boot with ubuntu and windows 7.
View 3 Replies View RelatedMy wife wants Ubuntu dual booted on her new Acer laptop which has Windows 7. My question: Is 10.10 stable enough to put on her computer? We have used Ubuntu for a number of years and have always stayed current with upgrades, but I have become leery lately of rushing into new versions of Ubuntu. I had too many problems when I upgraded to the last couple of times. I'm inclined to put 10.04 on her computer unless I can be assured that 10.10 is good to go. Or would I be well-advised to move back a version or two?

View 1 Replies View RelatedI bought a new computer (laptop HP DV6-1375dx) and I want to set a dual boot with win7, like I did with my desktop (clean install) However, my question is, with the new laptop all I have is the rescue disks vs. having the single OEM version. IS that a problem? for the desktop I followed lifehackers article "Dual boot win7 and ubuntu in perfect harmony." no problems at all.
what I am afraid of is formatting the new hard drive and the recovery partition and not being able to use the disks for some reason....am I over-reacting?
Until very recently I was running Ubuntu 9.10 (Karmic Koala) installed on a 20 GB hard disk and Windows XP (SP3) installed on RAID 1 array of 2 x 250 GB disks, very happily along side each other and using GRUB as the bootloader installed on the smaller 20 GB drive.
I have decided to upgrade to Windows 7, and was struggling with the installation failing with the seemingly quite common "Setup was unable to create a new system partition or locate and existing partition" error. Google seaching suggested unplugging my Ubuntu drive and then installing Win 7. This worked fine with the Ubuntu drive unplugged, however with the 20 GB plugged back in I can boot to GRUB, but it still has XP in the menu, and no option for Win 7.
I think I could get around the issue by re-installing Ubuntu, which would place GRUB on the MBR which is now on the 250 GB RAID 1 array, but I would rather have the system as it was before with GRUB and Ubuntu on the 20 GB drive.
I know I need to edit GRUB to remove the XP entry from the menu, but I have no idea how I would get Win 7 into GRUB, and what to do about the MBR which Win 7 put onto the RAID 1 array.
Currently i am dual boot win7 and ubuntu, and the win7 is installed first in C drive, then ubuntu 10.04 is installed in D drive, my question is can i uninstall win7 and just keep the ubuntu on my machine?
View 9 Replies View RelatedThere was windows 7 Home Basic pre installed onto Hcl Desktop at my Office, then I installed ubuntu 10.04 to it, everything was ok untill I restarted. When I select windows 7 from dual boot, it takes me back to dual boot grub page. So I did inserted Windows 7 cd and restored windows by this
Code:
bootrec.exe /fixboot
Now only windows 7 is working and booting. I want ubuntu 10.04 on the dual boot, how and what is exact method of recovering ubuntu without harming windows 7? Is it with ubuntu 10/04 cd?? If i do live cd and restore grub, will windows 7 work?? I haven't given any details of hd0 and root, i'll manage, just tell the procedure.
Should I first partition my HDD using partitioning software (Gparted ETC.)? I have Win7 as my primary but I just want some sort of linux OS on my laptop. I only want to give it 30GB, and I checked the partitioning helper that ubuntu 10.10 has on its installer and quite frankly, it sucks.

View 9 Replies View RelatedI've tried this a couple of times and can't load Ubuntu.Here's the scenerio, I have 3 partitions.
/dev/sda1 = ntfs (Win7)
/dev/sda2 = ext4 with the / mount point
/dev/sda3 = swap space
I've some tutorials where I need a /boot partition as well and others where I just need the root partition. At the bottom, there is a drop down box for you to select the device for boot loader installation. Those options include /dev/sda, /dev/sda1 (Win7) and /dev/sda2.
I need to do to get the dual boot working? My first thought is to install the boot loader onto /dev/sda but I'm unsure. It keeps booting Win7 and can't get the option to load Ubuntu.
Got a HP dv6-3019wm laptop yesterday and my attempt to dual boot has gone up in flames. I first followed the tutorial [URL]
I might have gone wrong by accidentally making the hard disk 'dynamic' after shrinking the windows partition. Upon booting the computer up after the 11.04 installation, Win7 gave me a 0xc0000225 error. The built in hard drive recovery didn't work and neither have multiple win7 64b recovery disks I have downloaded. A gparted live cd wouldn't boot. On attempting to reinstall 11.04 (so I can just get rid of win7), the installation freezes when it tries to recognize the state of my hard drive.
I've basically turned to dban, but that won't even work. The latest version gives me an error of "no configuration file found" and 1.0.7 give me "non-fatal error", even when I attempt to auto-nuke.
Am I out a hard drive?
I have a Windows Vista box upgraded to Win7 and then installed two (yes two) instances of Ubuntu 9.10 on the same box.
I don't need one of them (it had a corrupted install ISO disk) and want to remove the partition using fdisk or parted or similar utility.
How do I know which instance of Ubuntu is used for each partition I selected when I reboot the box?
There are two different versions displayed and I always select the newer one but how do I know if I remove the right one or not?
Also, when I restart in Win7, the BIOS/OS wants to check the disk everytime and now I've started skipping this check (it takes several mins).
I used to have a win7 hp laptop. I decided to use ubuntu9.10. i installed it to my second drive (d after shrinking of c: drive to 100 gb. After installation of ubuntu, i try to boot win7 from grub screen, it goes to blue screen and restarting, not opening. But when i choose ubuntu, it is working properly. When i try to repair it, the win7 cd does not see any drive, only its x drive (where it boots). how can i start my win7 again. I am working on this 2 days.
