SOURCE: Bios could not be loaded error code

Sure , you need to change the battery in your motherboard. Often it looks like a silver coin. What happens is that your bios setting are reset to default each time you restart PC, before updating bios (that is the solution from hp that you are trying), change the battery.

SOURCE: bootsafe error on hp compaq notebook notebook pc while booting

Boot from the XP disc and press R at the first screen. This takes you into Recovery Console. Run these commands:

fixboot c:
fixmbr
exit

The computer will restart and hopefully it will load Windows.

If not, is your computer making clicking sounds?

When you boot your computer, you need to hit the key to get you into the bios setup. F10, F2 or Del keys are the usual ones.

Once into the bios, change the boot order to make the CD drive first, and then you will boot right to the CD.

Note, you will also have to hit a key when it starts to boot, it will say, hit a key to boot from CD.

If you miss the key to get into the bios, you have to start over again. Sometimes you have to hit the enter bios key over and over to get in there.

How do i get to recovery mode for ubuntu?


  1. Switch on your computer.
  2. Wait until the BIOS has finished loading, or has almost finished. (During this time you will probably see a logo of your computer manufacturer.)
  3. Quickly press and hold the Shift key, which will bring up the GNU GRUB menu. (If you see the Ubuntu logo, you've missed the point where you can enter the GRUB menu.)
  4. Select the line which starts with "Advanced options".
  5. Select the line ending with "(recovery mode)", probably the second line, something like: Ubuntu GNU/Linux, with Linux 3.8.0-26-generic (recovery mode)
  6. Press Return and your machine will begin the boot process.
  7. After a few moments, your workstation should display a menu with a number of options. One of the options (you may need to scroll down to the bottom of the list) will be "Drop to root shell prompt". Press Return with this option highlighted.
  8. The root partition is mounted read-only. To mount it read/write, enter the command
    mount -o remount,rw /
  9. If you have /home, /boot, /tmp, or any other mount point on a separate partition, you can mount them with the command
    mount --all (This must be done following step 8 so that /etc/mtab is writable.) Alternatively, you could try selecting "Enable networking" in step 7, though this has been found to cause the system to hang (see https://bugs.launchpad.net/ubuntu/+source/friendly-recovery/+bug/981792).
NOTE 1: If you have Ubuntu Quantal (12.10) or earlier, omit step 4 (the recovery mode menu items are displayed on the top-level menu).
NOTE 2: If you reboot, there is no need to hold the Shift key in step 3. The GNU GRUB menu will continue to be displayed automatically on each boot until a normal startup of Ubuntu completes. To configure GRUB so the menu is always displayed, even after a normal startup, see https://help.ubuntu.com/community/Grub2/Setup.

How to Mount storage devices automatically on linux


Hi..
This will be nice that all your local Hard drives are mounted automatically during the boot. This can be achieved by modifying "fstab" (File System TABle) file. This file is located on /etc/ which would need superuser permissions(root user password) to modify.

How we can alter fstab and set system to mount partitions by itself is explained below..

  1. First Open a terminal and type blkid and press <Enter>
    this will show your local Hard disks with their UUIDs( Universal Unique IDentification). This may look like this

    nightflare.png
    here 1st column with /dev entries are the links of partitions(in the format /device/<Partition No.>
    2nd column : LABEL describes the Name or Label of partitions. Not all partitions necessarily needs a Label.
    3rd column starting with UUID is the entry shows the UUIDs of the Partition
    4th column shows the File system used in the partitions

  2. So Now we know some important informations about our partitions like their File system type and UUIDs. In linux to use a filesystem, we need to mount it in somewhere in the root directory. This is because of the Hierarchy nature of Linux .

    Usual location of mounted file systems are on /mount/ or /mnt/. I take /mount/ as my default Mount location. Create a new folder with a name(Without any space between words, ex: New_Partition) simillar to Partiton Label or No

    To create folders in /mount/ , we need root permissions.
    Open a terminal and type su and press <Enter>. It will ask for root password. type in root password and press enter.

    Then type mkdir -v /media/<Dir Name>
    ex.: If you want to create New_Drive in /media/ then type mkdir -v /media/New_Drive
    You can also create multiple folders in one step
    ex. You want to create Drive1, Drive2 , Drive3 then you need to type as
    mkdir -v /media/Drive1 /media/Drive2 /media/Drive3

    You may get as this
    nightflare_0.png

    Now we created mount points needed to mount the filesystems

  3. Now we need to modify fstab file .
    Default location of fstab is /etc/fstab

    nightflare_1.png

    On terminal ( where we typed commands to create folders in /media)
    Before we start editing fstab file, lets make a backup copy of it

    Type on terminal cp -v /etc/fstab /etc/fstab.backup and press <Enter>. You should see as below.

    nightflare_5.png

    type sudo gedit & and press <Enter>

    This will open text editor. Click on Open and point it to /etc/fstab

    nightflare.jpg

    It will Open fstab file. This may look like this

    nightflare_3.png

    Any entry starting with #, will not taken into account. So you can use # for commenting

    Basic structure of fstab file is


    <File System Address> <Mount Point> <Filesystem Type> <Options> <Dump> <Pass>


    File System Address --> Its is the Identifier for the file system. You can use either Links (ex.: /dev/sda2) or Labels (ex.: LABEL="DRIVE1") or UUIDs (ex.: UUID="74c9c3d9-a374-406d-ba41-e030c7d35f5d")


    Mount Point --> This is folder on which the file system mounts. (Refer Step 2) (ex.: /media/Drive2)


    File System Type --> specify the file system (ex ext3, ntfs, fat)


    Options --> Contains more complicated options
    For normal user, its good to set Defaults as Options


    Dump --> set whether to Backup or not. (ex. 0, 1)


    Pass --> set whether to check filesystem before mounting


    example of a edited fstab file is


    nightflare_4.png


    After finishing with fstab save it. You may get errors if you don't have permissions to alter fstab. In that case, Open a terminal and type su and press <Enter> and provide Password for root account. and <Enter>
    Then type gedit &.

  4. After saving the file , restart the system, if everything go just good as expected the computer boots up with local partitions mounted on specified locations


If you got any doubts , please contact me

Hard drive is not acessible


On another computer download and then burn the Knoppix disk.
Boot the Knoppix disk. Key ctl>alt>f1 to get to console session. Use cfdisk as follows:
cfdisk /dev/sda
or
cfdisk /dev/hda
One of these should you a listing of the partitions on your hard disk. Mount the main partition thus:
mount /dev/sda1 /mnt
or
mount /dev/hda1 /mnt
cd /mnt
Now you can search the partition and save files as needed.

What is grub error 17? how to fix it?


Its GRand Unified Bootloader used in Linux OS.
Normally you get this error when GRUB is not able recognise the partition from which you are trying to boot the system. Make sure the boot partition on your system is recognisable by GRUB (such as EXT3).

You can try to restore the GRUB using the LIVE CD
  1. Boot From Live CD
  2. Open Terminal Window
  3. type >sudo grub
  4. then type : find /boot/grub/stage1
  5. you'll get something like: (hd0, 1)
  6. then type : >root (hd0, 1)
  7. type: > setup (hd0)
  8. >quit
  9. >exit
Remove the Live CD and reboot the system.


Please let me know if you need any further assistance.

How repair redhat operating system the ask ctrl -d


whoops! You'll have to boot off of an installation disc, maybe Knoppix or Ubuntu if the RedHat install disc doesn't work. Once you do that you should find the old version of your fstab (often with a tilde ~ after it), restore the old version, and go from there!

Fsck error HELP! HELP ! HELP!


fsck is a file system error check command. Try the root password of nothing, (just the enter key), when ask for the password. Then use the fsck command to repair the file system before rebooting.
fsck - check and repair a Linux file system Try fsck with no options.
SYNOPSIS fsck [ -sACVRTNP ] [ -t fstype ] [filesys ... ] [--] [ fs-specific-options ]
DESCRIPTION fsck is used to check and optionally repair one or more Linux file systems. filesys can be a device name (e.g. /dev/hdc1, /dev/sdb2), a mount point (e.g. /, /usr, /home), or an ext2 label or UUID specifier (e.g. UUID=8868abf6-88c5-4a83-98b8-bfc24057f7bd or LABEL=root). Normally, the fsck program will try to run filesystems on different physical disk drives in parallel to reduce total amount time to check all of the filesystems.
If no filesystems are specified on the command line, and the -A option is not specified, fsck will default to checking filesystems in /etc/fstab serial. This is equivalent to the -As options.

Operating system


At a terminal, type:
fdisk -l
as root to see what drives and partitions are on your system. Let's say your partition is /dev/sda1. Next you need a mount point. I like to make and use /sd so type:
mkdir /sd
and to mount it, type:
mount -t ntfs /dev/sda1 /sd
and to view what's on the drive, type:
ls /sd
