Im using the System Rescue live cd to try and Clamscan a partition on my internal HD, but I cant mount /dev/sda3 (my home partition).
I use this commandline (as root):
Code:
mount -t ext3 /dev/sda3 mountpoint
but it just hangs, and then gives an error.
I have a netbook that dual-boots Win XP and Ubuntu 10.04 and accidentally hit the Win recovery mode in GRUB today, but quickly restarted without formatting or proceeding with any recovery. But upon reboot I just see: error: no such partition. grub rescue>
What I have tried so far: Boot to USB Live Disk... It won't, just goes straight to grub rescue.I do ls and it gives me (hd0) (hd0,4) (hd0,3) (hd0,2) (hd0,1) (fd0) error: fd0 cannot get C/H/S values.
set gives me
prefix=(hd0,5)/boot/grub
root=hd0,5
but if I try to boot it says unknown command so I figured I needed to find the right partition to boot from but I went through all of them with ls (hd0,4)/boot, ls (hd0,3)/boot etc. and every partition comes back "unknown filesystem".
I have been trying to install windows for 15 days and I was finally able to do it by removing in "disk utility" the sign saying that the fedora partition is bootable... but I did it when the partition was active... It showed me a message error but i thought that it told me it wasn't abvle to do it... and now that windows is installed I cannot any more access the partition either in rescue mode and on a live cd ... what could I do to access the partition either to save all the files or to (it woiuld be the best) reinstall the grub ?
View 14 Replies View RelatedBackground for the problem:
A. I have partitioned my WinXP LTop into:
--- WinXP NTFS partition
--- a vfat partition (mounted onto /fat32)
--- Installed F10 on ext3 virtual partition
B. I do not want install grub-loader in the Master Boot Record (that would loose my WinXP boot-loader for ever)
C. I have installed grub boot loader in the First Boot Sector
D. Now I have to boot using Rescue Mode, do:
1. dd if=/dev/sda2 of=/fat32/linux.bin bs=512 count=1
2. mount -t ntfs /dev/sda1 /ntfs
3. cp /fat32/linux.bin /ntfs
4. modify /ntfs/c/boot.ini and introduce the statement 'c:linux.bin="Linux"'
Problem: Im not able to do step D.2 above.
Symptom:
** after booting linux using the Rescue Mode: sh-3.2# chroot /mnt/sysimage sh-3.2# uname -r 2.6.27.5-117.fc10.i586 sh-3.2# mount -f ntfs /dev/sda1 /ntfs FATAL: Could not load /lib/modules/2.6.27.5-117.fc10.i586/modules.dep: No such file or directory ntfs-3g-mount: fuse device is missing, try 'modprobe fuse' as root
sh-3.2#
Observations:
* The rescue mode boots into i586 based kernel (I dont know what is the actual difference between i586 and i686 - will really appreciate if anyone can educate me about it). * The installation is only a i686 image and consequently there is *only* '/lib/modules/2.6.27.5-117.fc10.i686' dir and *no* other dir. There is no dir as xxxx.fc10.i586.
Last night I was making a boot usb drive with usb startup creator onto a USB external well I, messed up and lost the partition table for 2 USB drives: my 500 gb hard drive was pluged in whilst i was doing this silly i know it was partitioned 251 gb its now showing as 500 gb but the data is still on drive it seems the file system is gone or damaged

After some looking around I edited /etc/fstab to add the following line:
This works. But it mounts the windows partition from the root level. I'd like to just mount C:UsersFHSM (/Users/FSHM) to /mnt/windows.
I'm trying to get it so that when I click on the windows drive I get my windows user folder instead of having to click through from C: to get to it.
I'm the only user on this system but if I created a second windows user would my home folder mount for that person too or does setting the user ID prevent that from happening?

View 1 Replies View RelatedI am to reinstall the notebook of my father, that had Windows XP and Ubuntu on it. And I dont know anything on Ubuntu. My objective was to make a fresh install with XP only.So I was checking the partitions within Windows and found 7 or 8 of them which I could not understand: I asked to remove them, one by one, and got some error mesage on Windows. Now I understand these were probably used by Ubuntu.Now, when I restarted the PC,n I got:"error no such partition grub rescue"..I tried to boot from the CD - a windows XP setup CD, but I get blocked as well, because when I try formatting the drive during the installation CD it makes an error, or otherwise without formatting I also get an error.I guess the partitionning information of the hard drive is inconsistent, making everything fail.I dont know what to do.I am thinking to use a USB disk to reformat the HD, but I am not sure it will help.
View 5 Replies View RelatedOn a Linux CD/DVD, there are compressed filesystem images for the live version for KDE or Gnome for example, but they have no extension, but they are clearly an image file ( compressed filesystem images for the live version before installation ) !!
I was wondering, How do I mount these compressed filesystem images, after I copy the ISO content of the CD/DVD on my system .... I want to edit some files or packages and make some changes, like if I want to customize a live version of gnome for example ! ... ( I know you might be tempted to tell me to use KIWI etc to customize etc ..... ) ... but I want to be able to mount the compressed file system image, then edit it for reading and writing while it is in a subdirectory on its own ... i want to open it ! ... is there a way to do this ??? ... these type of files have no extension ...
i can open this compressed filesystem image then to edit for read & write ... before I roll it back again ..... If and when I succeed .... what should I watch out for ? ... will the same compressed file image but slightly modified work again ?
PS. that same question could be kind of translated or be extended like : how do I use unionfs/squashfs programs on the command line to mount these image files with no extension for read & write mode ???
I have two basically identical harddrives that are encrypted with LUKS containing a complete debian installation:
Code: Select allroot@x200s:/home/b# lsblk --fs

sda

└─sda5_crypt LVM2_member 21CS3f-SQeQ-XcMr-kyDs-OPtR-egmT-HkvJAu
[Code] ....
sda is what I currently run to write this text, sdb is my former harddrive, connected via USB.
I want to access the root partition on sdb.
The problem is:
Code: Select allcryptsetup luksOpen /dev/sdb5 oldhd
Enter passphrase for /dev/sdb5:
root@x200s:/home/b# ls /dev/mapper/
control oldhd sda5_crypt x200s--vg-root x200s--vg-swap_1
root@x200s:/home/b# mount /dev/mapper/oldhd /mnt/
[b]mount: unknown filesystem type 'LVM2_member'[/b]
[Code] ..
Before all this, both sda and sdb where in the same volume group. I renamed the volume group of sdb to "oldDisk"
using
Code: Select allvgrename <UUID> oldDisk
How I can access the data on the root filesystem of my sdb..
new partition is sda or,hda i bit confusing here

I Am Having Problem With My JFS Partition On Which Ubuntu Is Installed. It Is Not Mounting. The Bootscreen Says There Is Serious Problem With Mounting The Partition And It Does Not Load Linux. I Tried jfs_fsck -p and -a But With No Success. I Also Tried Checking For Errors Using GParted.
The Logscreen Said logredo failed and unrecoverable error reading M from /dev/sda5/ CANNOT CONTINUE. Is There Any Way I Can Repair This Or Atleast Get My Data Back?
I have a pc that was running with the latest version of ubuntu and i wanted to install just vista for somereasons.
And what i did is to format the main driver and try to boot it from vista CD and as you may guess i have an error that says: unknown file system grub rescue
Each time i start the pc. I have an ubuntu live cd and also the vista cd, so what should i do now? the vista cd dosnt boot and the same screen appears all the time.
When i boot my PC, i get this in my Fedora 16 distro. I have tried as following but none allowing me to boot anymore.

I recently switched from fedora 14 to 15. Today my computer suddenly shut down during an update, as I thought it overheated I decided to clean the cooling system and reapply thermal paste. However, now the system won't boot anymore ("kernel panic - not syncing : VFS: unable to mount root FS on unknown-block").
I would like to either solve this booting problem, or mount the fedora 15 filesystem and recover some files. Whichever is easier.
I have another drive with fedora 14 (antec below) which boots fine:

View 6 Replies View RelatedI am attempting to work with adding a new hard drive with a default logical volume setup. In order to complete the task, I am instructed to use a live CD to boot the system without mounting the drives using linux rescue. I am using CentOS-5.5-i386-LiveCD-Release2.iso
I have reviewed the centos documentation. When the live CD boots, it starts a count down to an automatic boot. I attempt to invoke the boot options as directed by hitting the tab and adding the words
linux rescue
At the end of the line and hit return to begin the booting process.
Unfortunately, the linux rescue boot option is ignored and the system mounts the hard drive. Additionally, I have checked the boot option several times by hitting the tab a second time and the option is not displayed.
In researching the issue, I inevitably get very similar instructions like:

My linux workstation recently crashed. After rebooting, Linux (Red Hat 5.3) will not boot properly and automatically went into emergency mode or recovery mode i think. I can still see my /home/user/ and all the files inside.I boot from CD to rescue mode and tried mounting read-only the /dev/sd5 which contains the files in the crashed hard disk to try to copy out my files but mounting was unsuccessful (invalid argument). I checked the filesystem type using fsck -N /dev/sda5 and shows it to ext2. i tried to mount another known working hdd and was successful.
My question is why in emergency mode, the crashed hdd is able to be mounted automatically as read-only but cannot be done in rescue mode thru a bootable CD?Is there any special mount options used in emergency mode?I also cannot copy out in emergency mode booting from the crashed hard disk as everything is read only.
I've a problem booting on my fc14 64 bit. I install it yesterday and everything was ok. Then I updated it and I installed wireless drivers kmod-wl equivalent to my kernel version that is 2.6.35.6-45. I've a pavilion dv6 with a broadcom ach. for networking. So the next step was installing kmod-nvidia for my nvidia geforce but after rebooting my never allow me to log in! I can se the tipical blue-white progress bar loading nvidia drivers but not else!
my screen freeze itself after the progress bar became white. I would resolve by rescue mode but I've installed fc14 64 b using a usb-pen drive and I find no way to do this from live version.

Recently I messed up GRUB boot loader in my laptop installed with Ubuntu which resulted in grub rescue prompt. So I had to boot Ubuntu Live CD to get it fixed. Thought of blogging it, may be useful for some one.
This fix involves two steps. First one is to chroot into Ubuntu installation partition. Second one is to install the grub MBR (Master Boot Record). I am using Ubuntu Lucid 10.04 and Live CD also of same.

got four partitions, one for media storage, one with ubuntu 9.10 32bit, one with crunchbang lite 9.04 64bit and one swap partition. The partition with ubuntu has been formated from ext4 to fat32 (with nothing on it, obviously). Whenever I boot up the pc now, I get an "unknown filesystem" error and a grub rescue> prompt. When I try to boot up a live usb image from my usb stick I either get a "linux kernel not found" message (crunchbang lite 32bit) or "initial menu has no LABEL entries!" error (gparted live usb) which changes to "Could not find kernel image: vesamenu.c32" after a couple of seconds. save my media partition or, more importantly, my crunchbang lite partition (which has one single important file on it, I'd love to recover). If this is somehow not possible, then I'd at least like to get my system usable again by succesfully booting from usb. I'm fairly new to using linux. I tried some grub-rescue commands, but not even the "help" command worked,

I have tried booting from a Live CD using Flash Linux and Damn Small Linux.
Flash Linux reports unable to mount CDROM and then provides a command line - I assume I have the kernel, a shell and little else at this point? Can I mount the CD and continue?
DSL seems to do something similar but freezes with a blank screen. I have the option of entering parameters prior to booting with DSL (but not with Flash) I have tried the parameter which copies the CD to RAM and then boots without success.
I plan on installing Debian to my HD in the near future but felt like playing around with Live CDs prior to this in order to get reacquainted.
I have googled this issue and it seems there are other noobs out there with the same model of PC (HP DV6) who are having similar problems but I could not find a solution.
As an aside - this is the kind of issue that IMO, still prevents Linux from becoming a mainstream OS.
Unable to install Ubuntu 9.10 on a new internal harddrive. The hardrive contains no operating system. This hardrive is the only drive present in the system.
