I have a Dell Vostro 1550 laptop with an Intel Core i3 processor running Ubuntu 12.04 64-bit. It shows me the error message: (initramfs) Unable to find a medium containing a live file system. in BusyBox, and it also says: Enter 'help' for a list of built-in commands.

I have just set up my new system by creating three partitions on a whole hard disk (/boot, /home, swap and /). I saw  article and now I am getting those errors and the system provide me with some options: (I to ignore, S to skip mounting or M for manual recovery).   I am forced to choose skip mounting because I don't know what manual recovery is. Despite the error I get I think that the system boots okay because I can use the system but this error is very annoying.

About 1/3 of the time that I boot my laptop, I get an error message that says  Error: Malformed file. Press any key to continue...   I press a key, and then my computer boots up and I can't discern any negative effects.  It's kind of disconcerting, and does delay the boot process.  How do I resolve this error and ensure my system is stable?

I need to add these modules because my usb keyboard is not working when I try to type my encrypted password. usbcore uhci_hcd ehci_hcd usbhid  I guess I need to add these to /etc/initramfs-tools/modules, but where exactly do i add them. Here is the modules file: # List of modules that you want to include in your initramfs. # They will be loaded at boot time in the order below. # # Syntax:  module_name [args ...] # # You must run update-initramfs(8) to effect this change. # # Examples: # # raid1 # sd_mod  Where am I supposed to add it here, and am I doing the right thing (is it safe)?

I don't know if it's the right place to ask but can somebody advise me for buying a ram memory for my computer.  I have a Dell Vostro 200 with 1GB of RAM and 667MHz. (2 x 512MB)  I want to buy raise the amount of RAM but I'm confused whether to buy 1 x 2GB or 2 x 1GB  I know it's the same for the available amount of memory but is ther a difference maybe in the clock speed so that 2 x 667MHz will be better than 1 x 667MHz. or maybe accessing one single memory slot will be faster and better than accessing two slots.  Please anyone helps.

And now I am unable to chmod it back.. or use any of my other system programs. Luckily this is on a VM I've been toying with, but is there any way to resolve this? The system is Ubuntu Server 12.10.   I have attempted to restart into recovery mode, unfortunately now I am unable to boot into the system at all due to permissions not granting some programs after init-bottom availability to run- the system just hangs. This is what I see:  Begin: Running /scripts/init-bottom ... done [   37.062059] init: Failed to spawn friendly-recovery pre-start process: unable to execute: Permission denied [   37.084744]  init: Failed to spawn friendly-recovery post-stop process: unable to execute: Permission denied [   37.101333] init: plymouth main process (220) killed by ABRT signal   After this the computer hangs.

I installed 13.04 as a virtual machine using VirtualBox from Oracle. When it was done doing the install, it says that it needs a reboot. After the reboot, I got this message:     Sorry Ubuntu 13.04 has experienced an internal error /usr/bin/compiz   I'm not sure what it means and how to resolve it.

I've tried to deal with this for days now with no luck. In this forum and also in other ones I can see a lot of discussion about this but none of the solutions have worked for me.  My current situation is that I've got some GBs "missing" that I can't free or find anywhere. I guess this is some kind of problem like memory leaks that only get fixed when rebooting, but I just would like to ask if someone has a better idea because there are currently a few customers on that server.  Here are some of the commands I've seen in other threads and my particular outputs:  df -h  Filesystem            Size  Used Avail Use% Mounted on /dev/sda1              19G   16G  1.8G  90% / tmpfs                 384M     0  384M   0% /lib/init/rw udev                   10M  1.2M  8.9M  12% /dev tmpfs                 384M     0  384M   0% /dev/shm   du -Pshx /* 2>/dev/null  4.8M    /bin 27M /boot 0   /cdrom 1.2M    /dev 8.8M    /emul 504M    /etc 4.0K    /grubconf 88K /home 60K /images 0   /initrd.img 147M    /lib 0   /lib32 0   /lib64 16K /lost+found 12K /media 4.0K    /mnt 4.4M    /opt 777M    /proc 57M /root 4.7M    /sbin 4.0K    /selinux 4.0K    /srv 0   /sys 4.0K    /tmp 332M    /usr 471M    /var 0   /vmlinuz   lsof +L1  (no output)   lsof | grep -i delete  (no output)   find / -size +50000 -exec ls -lah {} +;  -r-------- 1 root    root 777M 2015-07-21 06:19 /proc/kcore -rw------- 1 root    root  64M 2015-07-09 03:31 /sys/devices/pci0000:00/0000:00:06.0/0000:01:04.0/resource0 -rw-r----- 1 root    adm   49M 2015-07-21 06:19 /var/log/auth.log -rw-r----- 1 root    adm  174M 2015-07-19 06:25 /var/log/auth.log.1 -rw-rw---- 1 control mail 100M 2015-07-21 06:00 /var/mail/control   If you make the maths from du, for example, you get a few GBs, but nothing close to 16GB.  / is ext3.  OS is Debian 6.0  is there anything am I missing here?

I am using Dell Ubuntu Mini 10 version of Ubuntu.  The problem is: I tried both 12.04 and 13.04, but both are extremely slow on this laptop.So I am now running 11.04 which is near it's End Of Life and will give no further support.  So what should I do now? Is there any better option than using 11.04?

I dual boot Ubuntu and Windows 7. I was browsing on FireFox in Ubuntu and all of a sudden I get some error message, so I rebooted.  Now when I try to boot into Ubuntu I get this message:  fsck from util-linux 2.26.2 /dev/sda6 contains a file system with errors, check forced. /dev/sda6: Inodes that were part of a corrupted orphan linked list found.  /dev/sda6: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.

I am running an HP pavilion dv6000 dual boot win7 and Ubuntu 12.04. (well, up until today).  After a reboot, the boot process drops to the BusyBox shell and I end up at the prompt:  BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash) Enter 'help' for a list of built-in commands.  (initramfs)   I've been researching others who have had this same problem, but haven't been able to find any of those solutions to work for me.  I tried the method described , and after the final command   mount -t ntfs-3g /dev/sda1 /root -o force   it does nothing and gives me another (initramfs) prompt.  I can boot to a live CD (USB) and get to a terminal, but it doesn't seem to do much good, as I can see the /dev/sda1 in the ls command, but it doesn't recognize it when I try to cd to it.  One more question: using the command fdisk -l how can I tell which mount point (sda1/sda2) is my windows partition and which one is Ubuntu?

I have a Mini-ITX Intel DH61AG mobo w/ an Intel i3 processor and 8GB of 1600MHz DDR3 RAM. Anyways, this computer has been crashing kind of frequently. It is not an OS problem, as I have used Ubuntu (and had kernel panics), Windows 7, and Windows 8. Each of these OSes have had problems, so I ran a HDD check, and I know it is not a heat issue because I tested the processor for a few days when I first put the computer together. When I ran memtest86+, however, I got an error - so I did individual testing, and both chips came back good, did a really intense test with both of them again (took half a day), and no errors. So, I still think the problem could be RAM, but I am not sure - I tested it pretty extensively (might let it run all night again tonight)... which brings me to my point.   Could someone explain to me (in simple terms if possible) how to READ the minidump files of Windows computers? I've tried before with a guide I found online, but failed miserably. I'm fine with installing the software, I will probably need it sometime in the future as well. I have seen a few other posts on SU that just ask people to post minidump logs, but I feel as if that is too localized. Would someone be able to explain this?
