Ubuntu :: Access A File System On A Hard Drive From A Live CD?
Feb 7, 2010
What i really need to know is if there is a way to access a Ubuntu file system on a hard drive from a live CD. When i acess it now it just shows the Windows files on it, and i cant access the Ubuntu partition. What happened was this: I was trying to install Ubuntu on an external hard drive. I moved all the settings to the Hard drive so i didnt think it would affect my other drives. I mustve missed one of them because insteading of loading GRUB like it normally does, it came up with GRUB error 21 and did nothing. I tried to fix it, but nothing worked. I finally decided to unplug everything except the external and install it from there, so id atleast have a functioning desktop. As it turns out, my comp doesnt suport USB booting. So the only way i can use my computer is by Live CD. I was trying to fix things so i had both hard drives power supply unplugged. being slightly drowsy from staying up late that night, I plugged them in while my computer was on. the first one went in just fine, no problems. The second one though, also my master drive, i was having troubles pluging in. while i was turning it to fit in, it made a big spark and shocked my master drive. That drive had my MBR and Windows on it. Now It cant find a MBR, and i cant access the ubuntu partition on my slave drive. Is there any way to save this?? im 99.9% sure ive screwed myself over hardcore epically, but im hoping to save at least 1/2 my data.

I want to access my hard drive to copy over my old documents. So I boot into a LiveUSB, mount my ubuntu partition, and then cd to my home directory, but I can't open it. I get "permission denied." I encrypted my whole home directory and know the password, but how do I "decrypt" it or login as the partition's root so I can access the documents that way. I'm booted into the USB, but can't access the home directory. I get "You do not have the permissions necessary to view the contents of 'jake'".

I've installed F10-live.iso onto a usb key but am having problems with the non-privileged user I created. When I login as kurt, I do not have access to my home directory on the hard drive. I tried [root@localhost home] #chmod kurt kurt (after cd-ing to the correct spot), but still cannot access my files there. I can do so as Live System User, but not as me.

My wife's XP has crashed and I need to save files. I've discovered the command to mount the hard drive - unfortunately I need to force the mount, but I can't do it because I have to be in root. I can see the root user in the user list, but when I try to switch I can't access it. How I can do it to back up my wife's files. I have Kubuntu 8 and KDE 4.1.

I have a dual boot machine with WinXP/Linux Mint on it. I am looking to erase both of them and put up Ubuntu 11.04.
I have chosen to go with a live USB install for this. The live USB boots fine and everything seems usable. However, when I tried to install it would tell me that I do not have 4GB available for the install which seemed a bit weird since I have a 160GB Maxtor HDD.
After digging around a bit I realized that the system does not see my hard drive. Running fdisk -l would only show the USB drive that I am booting from and not the main HDD.
I tried to have a look in /dev to see if my HDD is there and not mounted. But aside from sda which is the USB I did not find an sdb or hd entry.
Has anyone encountered a similar problem while trying to install Ubuntu 11.04?
P.S.: The HDD works fine, I can see it in BIOS and in the other 2 OS-es that I have installed.

This probably isn't the best way to go about this, but I am pretty nooby. I took the hard drive with Ubuntu install and made it the second SATA drive, and then put a new SATA drive in as the first and installed Fedora on it.Now I want to access my files from the Ubuntu drive and put them on the new drive but when I try to access it, I can look at some files but the majority of them (like my music and a lot of my documents) it says that I don't have permission.Is there some way I can get to these files? I tried searching but I couldn't find anything relevant

I have a 1.5TB Western Digital Caviar Green in a USB 2.0 external setup with an ext4 file system. I'm going to purchase a 2.0TB Western Digital Caviar Green in a USB 2.0 external case, copy the data over and put my 1.5TB in a fire-resistant box in another house. I'm worried about a couple things however:
(1) I'm worried about the long-term viability of _any_ file system years into the future. I've been storing my data on hard drives (instead of CDs, DVDs or BDs) for years now due to their higher reliability than optical disks. However, the file system used in optical disks is UDF which I think has much longer viability into the future. I'm not going to store terabytes of data on optical discs of course, so I'm wondering what I should choose for a hard drive file system. FAT32 or NTFS (due to Windows' 90%+ presence on the desktop, including still being used by Windows 7) may be the best choice, but I much rather have a open source file system, especially one that allows for permissions, timestamps, etc.
(2) As for my 2TB hard drive that I will be using for a while into the future, should I continue to use ext4 (I've had no problem with it thus far), but is there another file system that has better performance when storing and transferring gigs of data?

when I load into Ubuntu 11.04 from my USB drive, why can't I access the files on my internal hard drive? I mount the drive but I cannot see any of the music, videos or documents contained on that drive (which is also an Ubuntu 11.04 drive). I was wondering so I could copy those files onto my external hard drive and reinstall since my Ubuntu crashed.

I installed ubuntu off of my laptop and put the Ubunto file system on a 1TB hard drive off of a drive enclosure. Now the only way I can access Windows is if the drive is still connected to the laptop. NO EXTERNAL HD No BOOT MENU when I boot up.

I've been installing/tweaking F12, and I've found something that I can't say I've ever seen or expected to find before: the contents of my ~/Documents folder has lost its permissions and ownership info. I restored it from a backup last night/this morning, and I've rebooted a few times since then. Other folders from the backup are OK, just Documents.I don't know what my options are. I could try to blow it away and restore it, but that doesn't answer what caused it. If there's a "relabel" or something, that might help... though I've never had to do it before. Could it be that after these two-and-some-change years, my hard drive is giving out? Good thing I have a recent backup... but it'd be a shame to lose all my work getting F12 to work again.

What file system should I use to partition a slow and old hard drive? I know that ext2 was best for old computers which mine is not but I am using an old hard drive for extra storage and I was curious if anyone knew if using ext2 or ext4 would show any performance differences.

I had a drive that kept kernel panic'ing so my data center recommended using the spare hard drive to reinstall OS on, and import the data from the old drive. (they checked the hardware, it wasn't the hardware) The new install is done, and I need to mount the old drive and get backups off it since my data center does not provide management whatsoever.
It's the same OS on both (Cent OS 5.4 32-bit) I'm an advanced user on windows, but linux gets me. I can ssh in, do basic stuff like setup IP ranges and restart services. I normally navigate the box through SFTP so I have a gui. WHM shows me my drives as such
Found Disk: hda
Found Disk: sdb
so I'm assuming SDB is my old drive and the drive I need to access. I attempted to follow instructions on
cyberciti.biz/faq/freebsd-adding-second-hard-disk-howto/
but I'm assuming FreeBSD would work differently and I wasn't totally sure what the labels of the file systems should be.

I have a Toshiba laptop that seems to be freezing on extended operations involving the file system/hard drive. (that's kind of a guess on my part). The system has frozen during the last day or two when I:
- try a large file operation with Nautilus
- try exporting a large video file from Kdenlive
- try formatting the disk for a new install of Maverick (I decided that with the new version almost out, I might try upgrading in case I broke my system)
What I see is the screen freezing and the mouse does not move. As I said, I tried installing the Maverick RC from the Alternate CD (I wanted to do a minimal install). The install hung on the partitioning step and the caps-lock key started blinking (though I don't get this in other cases). I have booted into my Lucid live-cd and a Puppy live-cd to try Gparted, with the same results - the system freezes (but the caps-lock key doesn't blink). Puppy HAS performed better generally, for example I was able to complete my large file operation (backing things up!) but it is freezing on the partitioning step.

i needed to change my external hard drive's file system from ext3 to fat32, to use it in windows, which i did the simple way: i shrunk the ext3 partition, made a fat32 partition, copied the files over, removed the ext3 and made the fat32 bigger. unfortunately, while gparted was making the partition larger, my computer shut down. i lost all my files and the partition messed up immediately. i made a new fat32 partition, after deleting the old one, but noticed that gparted was showing 100 gigs already in use (???). so now i have a 300 gb hard drive with only 200 gb i can use; i ran df to make sure gparted wasn't messing up, but indeed it shows the partition as being only 200 gigs in size. i haven't tried making any other kind of partition yet, such as ext3, for fear of losing my files again, and because it wouldn't be permanent anyway, because i need those files in windows and stupid microsoft won't make their OS ext3 compatible.

It started when I wanted to dual boot Windows 7 and Opensuse off of my netbook (No DVD/CD drive) I tried install suse from an external hard drive and I botched it. I ended up erasing EVERYTHING off of my internal netbook hard drive. Windows and all.
Well, I had a couple of other computers so I studied up and eventually successfully installed OpenSUSE 11.2 on my external hard drive (11.3 being the one that I accidentally erased everything with, so kinda scared of it) and now I want to install openSUSE 11.2 on my internal netbook hard drive.
I can not use disks
I can not use a flash drive (For some reason, even if I make it bootable, it will not load up, this could be because it's actually a 8GB microSD card that is placed in a USB card reader.)
I can not use an external hard drive because that's what I'm running suse off of.
I've tried reading up on how to install suse on another drive off of the hard drive and I've gotten as far as whenever I boot up the netbook with the suse external hard drive connected it will ask to boot into OpenSUSE, the Fail Safe, or to install OpenSuse. When I select to install it it gives me the Error 18 Unknown File system.
I've tried formatting the internal hard drive twice. One as NTFS and again as EXT4. Neither seems to effect it other than when it's ext4 I can open it and it contains a Lost and Found folder.
When I interrupt the boot sequence by pressing c and going to the terminal and I use the root (hd +TAB command it tells me I have a hd0 and a hd1. The hd1 only has 1 partition which is ext4, which I'm assuming hd1 is the internal hard drive (I'm not sure how to check) and the hd0 is the external hard drive, which has three partitions. One with an unknown file system and two with ext4. When I try to enter the set up from the terminal it gives me the same error for any thing I put it (e.g. root (hd0,0) gives the same error as root (hd0,1), or root (hd0,2) and root (hd1,0)
Something like it cannot locate these two files I'm assuming it needs to boot. If anyone finds this relevant I'll retry it and post the files its missing.
I've been searching for awhile and can't find any threads that can solve my problem. From other threads, however, I have noticed that I should probably include my menu.lst, listed below
Code:
I have also ran the boot info script and received the RESULTS.txt file it generates. Listed below

For some reason, Ubuntu 10.4 LTS cannot boot normally, so I have reverted to a live CD, no concern, I can just reinstall, what I am concerned with is the fact that I get my music. I load up the live CD, and I am able to access my hard drive, but I as I found my music folder, I cannot copy and past and/or move ANY folders into a flash drive. It says I do not have permission.

I'm mostly a linux-idiot but I tried to get an update for a laptop that was running xubuntu. Anyway, it won't boot and instead takes me to a screen where it says "press s to skip mounting, or press m to recover manually" or something like that. I've pressed S, and then it tells me that it can't find /tmp or something, and I have to turn it off and back on to do anything. Pressing M doesn't help much either... at least not for a mostly-linux-idiot like me. I would do a clean install, but there are a few files I absolutely have to have from the hard drive. recover the files I need from my hard drive to a usb drive while using a Live CD?

I have just finished building a new computer and it booted with no problems from the hard drive to ubuntu 10.10 (it was a hard drive from a previous computer and had ubuntu installed). After less than a minute though it froze up completely. I restarted and now cannot get ubuntu to boot. I get to GRUB with no problems but when I try to boot ubuntu I get a black screen with a blinking cursor in the top left corner and it hangs indefinitely.
I tried to boot from a live cd to see if there was anything I could do but I get as far as the screen to choose "Try Ubuntu" or "Install" and both choices leave me on a black screen with the mouse icon. I can move the mouse but nothing else. I have tried the Ubuntu 10.10 32 bit, 11.04 64-bit, 11.04 32-bit and even Mythbuntu, which I had on a cd from a magazine. I get the same result with all of these.
On the other hand, OpenSUSE 11.4 boots from the Live CD fine and I installed it and it boots from the hard drive. This is good news but I would much prefer Ubuntu, as I'm more used to it. Am I doing something wrong or have I any hope?
The computer specs are:
Processor: AMD phenom II X2 555
Motherboard: Asus M4A88TD V-EVO
Memory: G-Skill Ripjaws 4GB Dual channel
Hard Drive: Seagate Barracuda 200GB

A recent update messed up my Ubuntu (actually Xubuntu) laptop, and so I want to recover a few important files off of it before reinstalling the OS.I cannot boot into Ubuntu on my hard drive, so I put in one of my Live CDs, but couldn't figure out how to get the files from my hard drive.I googled the problem, but all the solutions talked about recovering Windows files with a Live CD.I need to recover my files that were in Ubuntu

I just setup an old computer with Suse 11.3. My goal is to store all my movies and stuff on the Suse box and access them through my home network. I have 11.3 installed, got the network setup and working, can access the internet, access files to/from my laptop to Suse box, and can even access movies/files on the Suse box from my WD Live media box. The problem is: when I add an external drive to the Suse box my WD Live does not totally 'see' it. he external USB drive is accessable on the Suse box as I've moved files to and from this external USB drive. The drive is a WD MyBook. I setup sharing in Samba and the WD Live sees the drive but cannot see the files. Is this a permission thing? Pretty sure I setup Samba correctly as I share several directories in the Suse box.

Is there a way to install grub2 from a linux live cd when linux isn't installed on any of the partitions? I'm setting up a multiboot partition for someone and I don't want to install linux anywhere on the computer since hard drive space is running short.

I decided I'm going to go back to a dual boot to see if I can get some of the slackware issues resolved on my laptop; its ubuntu only at the moment due to wireless problems. I've only got one hard drive so I can't simply unmount and repartition from gparted, I've lost all of my random linux live cds, and can't find a spare blank optical disc. Is there a way to boot from directly from the iso or from a flash drive or something?

If an old bios and mainboard is being used, such that it cannot handle the large size of HD, then is it useful to say use a live CD and from its initial menu (pressed a key), choose 'Boot From First Hard Disk'? Would this be similar in getting around a bios and disk size limitation I wonder - like - does the use of a live CD in this way avoid using the bios to point to the active partition??
The reason for asking is that a friend has a couple of quality old rack mounted server machines and wants to use Ubuntu having now fitted 80 GB empty drives. Live CD seems ok, and 11.04 install goes ok but on boot up grub comes back with an error.
I recall that early machines cannot see larger(?) HDs for booting purposes even though installs go ok in very large HDs. I wondered if a live CD to boot up temporarily - trouble shooting - would be worth trying for this reason, or am I way off?

I tried to use Grub to boot the Fedora 14 Live CD from its ISO image (SHA256 verified) on the hard drive. I put Fedora-14-x86_64-Live-Desktop.iso in the root directory of the FAT32 partition D: (sda5) then extracted isolinux from this ISO, and put it on D: I followed the isolinux.cfg file, and wrote a menu.lst as follows:
title Fedora 14 Live CD
root (hd0,4)
kernel (hd0,4)/isolinux/vmlinuz0 root=live:CDLABEL=Fedora-14-x86_64-Live-Desktop rootfstype=auto ro liveimg quiet rhgb
initrd (hd0,4)/isolinux/initrd0.img
However Grub told me: No root device found. Boot has failed. Sleeping forever. Here's the contents of isolinux.cfg:
