Boot from USB or DVD with UEFI bios upgrade

Hello

I have an Alienware Aurora R4. I am trying to upgrade the BIOS A03 to A05. My system uses the UEFI boot loader. I have problems starting in anything except through the windows.

I tried to make a bootable USB flash drive with both the HP disk storage format tool and Rufus using the win98 and FreeDOS as the operating system. The bootable flash drive is recognized when I do F12 and I chose to start. It goes straight into windows.

I tried to boot from the drivers and utilities disk and once again, he is going directly into windows.

In my BIOS, I value UEFI then CD/DVD the HD device boot order and still it doesn't start from one of these devices.

Is it possible either due to UEFI? If I understand correctly this is a 64-bit application and will not recognize any OS 32-bit like BACK. Is this true?

What I have to go into the BIOS and change it for a legacy instead of EUFI start-up and if I do this will I have no problem starting after I do the upgrade of BIOS and return to EUFI?

Thank you

Mike

I think that you have solved your problem.  If you need boot from a USB device, it will boot UEFI information appropriate unless your BIOS has an option to return to the start-up inherited automatically.

Updated the BIOS normally resets the configuration to the default configuration for the computer.  If you are unable to update the BIOS, you will need to look through the BIOS configuration page to ensure that your settings are correct.  I would not be surprised if the first parameter you have to do to come back to the UEFI boot mode.

    Hi all
    I would like to ask if it is possible to start the laptop (T.Satellite) an external USB CD/DVD. I have this necessary cause my CD/DVD-RW is not working and I would like to reinstall the system on the Toshiba CD with the hope that everything will start to work again properly. I try to go into the BIOS to change the sequency of startup, but I don't have the ability to put an external USB device. Thanks in advance for any suggestions.

    Hello

    You should tell us what model you have because some models may support this and isn't the most.
    In general, I would say no, though. Very few models support this. The only one, I know in my head right now is the Portege M200. Other models later, it can support, but I can't say right now. It's better if you tell us that you you have.

  • NB200 laptop cannot boot from USB CD/DVD drive / blinking cursor

    I have a toshiba nb200 - 11L, a little less than 2 years (no guarantee!). Recently, it has developed a problem that prevented him from starting the system and all that happens is I have a flashing cursor in the upper left corner of a black screen. The partitions of the options only are F2 and F12, but these will not allow me to enter in safe mode or use the toshiba recovery option.

    I bought the toshiba on cd rom recovery disk in order to complete a re - install but the bios displays only the HARD drive and floppy drive as an option and it doesn't seem to be any way to add new options.

    I checked the hard drive that seems to be ok. I fear that the problem may be the motherboard that I think will make any repair uneconomic.

    Any suggestion will be highly appreciated.

    Thank you. Keith

    Hi @kvartsnorsk

    Welcome to the Forums of HP Support!

    I know that you are looking for drivers for Windows XP, unfortunately, this laptop was not sold configured for this OS. Drivers are available for windows 7 and 8 (32 and 64 bit)

    What happens if I do not see my operating system?

    On the boot USB device, it is likely that your bootable usb image isn't UEFI, so you should enable legacy boot in the BIOS to allow boot off this device.

  • Unable to boot from USB or ODD after that windows 8.1 update on P850 - 31L

    Hello

    I just updated a P850 - 31L for windows windows 8.1 8 by the windows store.

    Before the update, I was able to boot from a USB key by pressing F12 during the boot upward.

    After the update I was more able to boot from the USB drive. Select the USB key by changing the boot order in the setup of the BIOS via F2 or pressing F12 is no longer works.

    Booting from ODD also is no longer possible.

    The version of the BIOS is 6.70 and does not secure boot must be disabled. However the DVD and the USB I tried are signed Ubuntu 12.10, who worked before the upgrade. Fastboot in windows 8.1 is disabled.

    Then, this seems to be a bug in the BIOS Toshiba? Or a windows 8.1 update the BIOS or the boot EFI in a way partition replace the BIOS setting? Really stuck here, does not seem to be much information.

    Any ideas or help would be very appreciated!

    Thank you

    Update: I just tried to boot from the DVD of windows recovery 8 Toshiba and this does more or the other.

    Post edited by: michael_toshiba_forum

    OK I fixed that.

    First of all, it is to note that it is possible to turn off secure in the 6.70 BIOS startup.
    However this option is only available when the password is not defined in the Security menu.

    After activation or deactivation of the password a reboot is necessary to make the secure boot toggle option is available or not.

    It's good that I guess I assume that it can prevent secure boot are disabled when the machine is running. However this does not seem to have been associated with this problem.

    I selected the option "reset to factory defaults" in the output menu.
    The machine is then able to boot from USB and DVD. The boot order was also respected.

    Perhaps upgrading windows 8.1 corrupt invisible somehow the BIOS settings. Or maybe it was just a stranage coincidence that the BIOS itself corrupted during the installation. Anyway this factory reset fixed.

    Hi I'm trying to boot from usb on a desktop HP ENVY 700. I don't know the serial number now.

    I followed the instructions and have produced a bootable USB and I checked this on a work dell computer where there is an option for me to boot from my USB if I so wish, but on my HP ENVY any options choose it does not appear with my USB in question and when I try to change the boot sequence making sure the usb/floppy and drive hard usb is above the rest of the sequencers starting it always starts just to the top as usual to my windows boot 10. I've disabled secure boot and used the boot of the legacy and it still does not work.

    I went through all the options I can that seem to be logic and it just does not work. I don't understand and I have to start using a usb key that I use the operating system can be very dangerous in a real environment, so it can not be downloaded to the hard drive.

    I need immediate help, this becomes quite frustrating now that it should be simple to do, but HP is not the way to simplisitic to do.

    Please if someone could point me in the right direction I would be so appreciative ideally if I could have a ride on the way to do

    > 1. How to create a DVD repair or start for windows 8.1 pro with UEFI Bios and boot secured.
    To be able to boot from sources other than the drive HARD internal, the boot mode must be set to the CSM and secure boot must be disabled!

    Your laptop has been preloaded with Win 8. Right? For example, the USB flash stick memory you just use the Toshiba Recovery media creator contains the Image of Toshiba with Windows 8. Don t mix this Toshiba image with the image that can be created using Microsoft's own backup and restore function. Both are different pictures!

    The last partition contains the files on HARD drive recovery. Usually this partition will be created again when you use the Toshiba Recovery disk to put the laptop back to factory settings. So in the case where you n t need this files or the partition, you can delete

    In addition, the 'trad' updated BIOS available for PSP26 zip file contains one... of files windows self-extracting (?), rather than the usual set of files including a CD iso image. (But in any case, it is very old...)

  • Cannot get Z3 - 615 to boot from USB or CD/DVD

    I've been trying to get a Z3-615 to boot from the CD/DVD or a USB bootable device. All my attempts have failed. I have checked all the settings of the bios, changed the boot order and all other options. I try to boot from a well-known Windows 7 disc. I tested the CD and USB on other devices and they work perfectly.

    Any suggestions would be greatly appreciated.

    to install windows 7 on your desktop, you must move from UEFI to legacy, disable secure boot and allow to launch the CSM.

  • Problem when booting from USB and bootable DVD

    I tried to boot from a bootable DVD to try Linux and install it. So pressing F9 to select the boot device, so I chose DVD ROM drive But it still does not start.

    Note: It starts on the first run. When I restart the PC and try again to start from the DVD, it jumps the DVD playback. Same thing happens with the USB key. I tried all USB ports.

    Another time all USB ports too and this pen drive work well and the DVD. Don't know what the problem is.

    Please tell me is there any problem with the BIOS?

    Thank you.

    In each market, unless F9 (for most HP computers and laptops) is selected to change the order, BIOS will look on the bootable devices (USB HDD, ODD,) in the order that they are configured in the BIOS settings.

    A usb device is not in the list of the BIOS boot order, as it is generally not available and only temporarily inserted.
