Question about Toshiba Satellite L855D-S5220 Laptop

Toshiba boot screen won't appear when turned on

I want to boot my toshiba from a usb drive carrying ubuntu. I was able to do it several times yesterday. But when I turned on the computer today, the toshiba logo does not appear nor does pressing F12 take me to the normal boot menu (it takes me to a screen that says "choose OS" and "press F8 for advanced booting options"). Instead of the toshiba logo and option to press F12 to go to boot menu, the pc shows a black screen with the flashing underscore in the top left corner then it starts windows. I have windows 7. Also the fn keys are not working the same way. When I press fn+F12 it turns on/off the wireless, but when I press the wireless button (F12) it will take me to that alternate boot menu asking me which OS and so on. Please help. I would like to be able to restore the boot menu and the old key combination: fn+F12. Yesterday I did play around with the boot order in system settings. But I can't access any of that. Isn't there a separate fn key to load system settings, that would solve the problem, I think.

My first response is to ask if you have upgraded to the latest BIOS. If no then I would suggest that you do that first. This sounds like the BIOS may not support booting from a USB drive. You need to go into the boot options portion of the BIOS and see if a USB drive is part of the options. If it is the move it head of the hard drive on the Laptop. This will make the USB drive if it is installed the first device to look for when trying to boot. Now on some systems if the USB drive is not bootable the process will hang as there is no OS on a high priority boot media.

It will help if you mention the Toshiba model so we can ascertain which BIOS is running. But in general, take the USB out of the slot, and then when the machine starts up, press F2 when you see the prompt.
Alternatively if you do not see the prompt screen, press the ESC key for 3 seconds immediatley as you start the machine and then F1- that should present you with the Setup screen

I would contact www.toshiba.com amd speak to the technical department, they are very helpfull. It may be a RAM fault or a hard drive fault but as you have data on the drive, I don't want it to go pear shaped and for you to lose any data.
Hope that helps.

Need to update bios toshiba satellite c660,using ubuntu live dvd, will not boot hard drive, all normal recovery options used up


Hi There,
There are currently no easy ways to update a bios through linux at all - including live cd's. Your best bet is to make a bios update USB stick (or floppy depending on the age of the computer)
Here's a link to those instructions:
http://www.biosflash.com/e/bios-boot-usb-stick.htm
Alternatively, speaking from my own experience with a similar situation, you can take the hard drive out, use it in place of the usb stick, boot from it, update your bios, and go from there.

Toshiba satellite M45-S169 won't boot ubuntu from DVD


Your really pushing the lower minimum requirement limits if you're trying to use Ubuntu 11 or Ubuntu 12. Especially with your on-board graphics chip which borrows system ram.

Try Ubuntu 10.04.4 LTS (Lucid Lynx) instead.

Go Here and download the 1st link on the list under Desktop CD:
http://releases.ubuntu.com/lucid/

OR...

Here is a direct link to the ISO file you need to download and then burn to a CD:
http://releases.ubuntu.com/lucid/ubuntu-10.04.4-desktop-i386.iso

If you don't have Software for burning iso's to CD's then download and install this totally FREE CD Burning program:

The laptop won't boot


probably the hard drive in your laptop is gone.
try booting ubuntu in live mode, so without installing it.
when the boot is completed, launch the tool gparted and see if it detects the hard drive: if it doesn't, you need to change the hard disk..

No operating system found can't boot from usb there is no boot from usb option


Did you try pressing F8 key at boot up?

  • 1

    Turn on your laptop and look at the first screen that comes up as soon as it is on. This screen will tell you "Press x key to enter setup", replacing "x" with the actual BIOS access key. It's usually "Del" or "F2" on Toshiba systems.

  • 2

    Press the key firmly and quickly before the screen goes away. If you do not react quickly enough, you will miss the window of opportunity to enter the BIOS. On Toshiba systems, this window of opportunity is somewhere between two to five seconds.

  • 3

    Navigate your BIOS configuration screen to the "Boot" tab. It is usually just before "Exit."

  • 4

    As the first boot device, select "USB," or "USB HDD." If you have a "USB ZIP" option, you might be able to boot from it, so select that if you have no other choice.

  • 5

    Press the button for "Save and Exit" in your BIOS. The correct button is usually F10.

    My acer aspire 2920 goes black screen when I try to boot Ubuntu from USB. I thinking of reset the bios. Please help me with the procedures


    Hi there. It won't be a bios problem if it allows you to selet the usb to boot from. Sometimes when you try to boot ubuntu off of a usb it gives you a black screen for as long as 2+ minutes. usb drives can be slow but if it still will not boot then it is likely a problem with the boot loader on the usb stick. I would try installing ubuntu to the usb again to see if it works. If it still won't work then there is more than one way to install ubuntu to a usb. Leave a comnent here if you still can't get it to work and i can give you some more instructions of how to make it work. It shouldn't be a problem with your computer though.

    I just installed a brand new HDD (Toshiba MK6034GAX). This is the same model HDD that came with laptop. Trying to install Linux (Ubuntu). Can I do a clean install from the USB port? I have a Toshiba...


    Yes as long as you make sure in BIOS you have it set to boot from USB before the HDD.
    On the Ubuntu site from the download page are instructions on how to create a bootable USB for Ubuntu.

    I need pointer to tool/software preferably recommended by Toshiba thru which I can check health of my Hard Disk - MK4021GAS.


    I recommend going to ubuntu.com and downloading the latest version of Ubuntu. Burn it to a CD or USB Drive, then boot off of it. Once you get into the Live mode (Try without installing), open Disk Utility, and you can run diagnostics on and check the health of your drives.

    Booting from a USB Stick


    Here you go:

    Download the Ubuntu Live ISO (if you dont have it already) and burn it to CD
    Restart your computer (booting from the Ubuntu Live CD)
    Insert a 1GB or larger USB flash drive
    Open a terminal window and type sudo su
    Now type fdisk -l to list available drives/partitions (note which device is your flash drive Example: /dev/sdb). Throughout this tutorial, replace all instances of x with your flash drive letter. For example, if your flash drive is sdb, replace x with b.
    Type umount /dev/sdx1
    Type fdisk /dev/sdx 
    type p to show the existing partition and d to delete it
    type p again to show any remaining partitions (if partitions exist, repeat the previous step)
    type n to make a new partition
    type p for primary partition 
    type 1 to make this the first partition
    hit enter to use the default 1st cylinder
    type +750M to set the partition size
    type a to make this partition active
    type 1 to select partition 1
    type t to change the partition filesystem
    type 6 to select the fat16 file system
    type n to make another new partition
    type p for primary partition 
    type 2 to make this the second partition
    hit enter to use the default cylinder
    hit enter again to use the default last cylinder
    type w to write the new partition table
    Type umount /dev/sdx1 to unmount the partition
    Type mkfs.vfat -F 16 -n usb /dev/sdx1 to format the first partition

    "Alternately you can try mkfs.vfat -F 32 -n usb /dev/sdx1 (doesn't always work)"
    Type umount /dev/sdx2 to ensure the partition is unmounted
    Type mkfs.ext2 -b 4096 -L casper-rw /dev/sdx2 to format the second partition
    Remove and Re-insert your flash drive
    Back at the terminal, type sudo apt-get install syslinux mtools
    Type syslinux -sf /dev/sdx1
    Restart your computer, remove the CD and boot back into Windows

    Using Windows to prepare and move the files to the USB Stick:
    Create a folder named USB on your computer
    Download UBconvert.zip using this link - http://www.pendrivelinux.com/downloads/UBconvert.zip
    Now, extract the files to the USB folder
    Move the Ubuntu  ISO downloaded earlier to the USB folder
    Click fixu.bat from the USB folder (follow on screen instructions)
    Move all files from the ubuntu directory to your memory stick
    Reboot your computer and set your system BIOS to boot from USB-HDD or USB-ZIP. Also set the "Hard Disk Boot Priority" if necessary.

    You should now be booting into Ubuntu Linux from your USB drive!
