• HP 15 r036tu: unable to boot from USB

  I'm unable to boot from a USB key, I started correctly the USB, it works on other laptops but not on mine. I also changed my boot order in the bios, but still, I'm not able to boot from USB. I read somewhere that it's because of security windows 8.1 can you help me with this.  Thanks in advance

  The trick to this is to use a utility that will make your USB boot EFI and MBR.

  The following link goes to a third party site with free downloadable open source utilities to do exactly that and even more.

• 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

  Michael

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

  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.

• Unable to boot from USB 3.0 E430

  Hello community!

  I recently got a ThinkPad E430, and I love it.  I have a minor problem with the boot.

  As a Linux user, I regularly boot from usb and cd while trying different distributions and whatnot.  However, I discovered that I can't boot from my USB 3.0 ports.  Not only that, but my computer does not start if I have nothing plugged into them.

  I first thought that I had faked my dd command in the transfer of the image, but the usb key works from the 2.0 port. So I thought maybe it was the usb key itself, but this happens with all my usb 2.0 flash drives and 3.0.

  I noticed a recent bios update a few days, but I don't want to go through the trouble, if she does not really bring all the benefits.  Actually looking at the itt changelog says that it only supports to the B430.

  I guess I would really just know if others in the face of this problem.  Thank you!

  My E430 fine boots of USB3.0 ports.

• 700 - 147C envy: cannot change bios to boot from backup USB Acronis. Startup command problem

  I tried to boot from my USB Acronis boot device to clone my C: drive to another HARD drive, but I was unable to set the boot order (first USB) because it keeps resetting & put the USB back where it was before.  I've done this before without problem; I wanted to boot from an external USB Acronis rescue disk & run the procedure to clone of it. The USB is listed in the startup as list "Sandisk Cruzer 1.27 & it's the ISO boot Acronis on this file but I failed to get the pc to boot from it.» (not this time in any case). After a needless frustration 3 hours I ran successfully clone of C: drive procedure.  I checked the clone by disconnecting the source & boot from it, but it works "BOOT PXE ON IPV4 followed by PXE BOOT ON IPV6 before it starts the clone. The startup disk is listed before the lines of IPV in the bios then why what is happening?  I disabled the 2 procedures of IPV with F5 & now it starts normally, but I do not consider this problem solved, because I have not yet able to boot from USB & I don't know why I had to disable these 2 lines.

  Addendum: I revisited the right bios & reactivated 2 disabled lines & it is now booting properly, no nonsense IPV. Go figure.

  Help!

  Hello

  I've seen similar problems before.  I solved me my clearing the CMOS and then start with only a UEFI (the main HD) compatible device. After that the problem had gone away, I reconnected it and then my other active UEFI device.

• Booting from a USB key

  I lost the admin password and I downloaded software that will recover what forces me to boot from a USB key. My computer is a h8-1409. I tried everything, but I can't see anything that would allow me to boot from my USB. I was wondering if we can not even boot from a USB?

  I use an own USB with only installed startup files programmed. My USB is a Lexar 16 GB.

  Please help as I am unable to do anything without my admin password.

  Please check that the following BIOS settings are defined as follows:

  

  All the ACTIVE USB port

  

  Start quick disabled

  You will have to also ENABLE 'Legacy Support' and DISABLE 'Secure Boot'

• Alienware X 51 R1 unable to boot from the CD

  I've noticed lately that my x-51 R1 running Windows 7, is unable to boot from the CD/DVD drive using the UEFI. I tried with a CD of Linux for the class, and I'm trying to reset my HP MediaSmart Server old ancestors via a disk recovery and in two attempts, the computer will boot directly from the HARD drive.

  Installation boot is CD/DVD, USB, CD/DVD or HARD drive.

  UEFI BIOS is

  Computer is running that Windows 7 Home Premium, Intel i3-2120 3.3 GHz bought in December 2012.

  Any help would be appreciated, I will try to answer all questions as well.

  Calling Customer Service would be good, but they try to charge me...

  The UEFI boot sequence does not take too kindly to optical drives. It is best to make a USB bootable using Rufus:

  For an example, see here:

  If you make a recovery media using the latest version of Respawn Alienware be sure to use USB (USB key or external hard drive USB) and not a DVD media:

• How to get the computer to boot from a USB?

  I use offline windows Defender. Start the computer to the USB you need. How can I get the computer set up to do this?

  my computer is a HP Pavilion e9100z.

  Thanks for any help

  Hello

  We will determine if your PC can not even boot from USB devices.  Plug the USB and turn on your PC.  When you get to the HP splash screen, then start typing the escape key to bring up a boot selection menu. If you do not see the USB device then your PC can't boot from a USB device.

  If your PC does support booting from a USB device and then read this MS post article.

  You always have the option to start Windows Defender from a CD or a DVD.

• Pavilioin P6710f: Changing Bios then boot from a USB flash drive

  How can I update my bios to enable booting from a USB Flash drive. My bios is American Megatrends 6.07, 04/05/2011 and the only options are CD, hard disk, floppy. Is there a way to change this? To test the Windows 10 repair disk I created, my system froze to the blue screen "choose" keyboard layout. I couldn't use the usb mouse or usb keyboard. As a result, I had to restore my system to windows 7 using my Norton Ghost recovery disk and backups that I had done before downloading windows 10.

  After the opening of the bios and clicking on the hard drive by default, I found that I had a choice, including the USB Flash drive that I have pugged just forward to restart. This answered my question. Thanks to everyone for their contribution. It was not necessary to Flash the bios after all.

• Why I can't boot from a USB?

  Hello

  Why I can't boot from a USB?   I'm looking to replace a failed hard drive in a Mac Mini 2010. I replaced the hard drive without difficulty.

  I have a USB flash drive from known good 10.10.5 with an Installer (tested) well known about it.   I press the power switch, as soon as the startup chime plays, I press the Option (Alt) key.

  One of the two following situations occurs. Sometimes, I have a small screen asking me to enter my password Wi - Fi. I get my password and nothing else happens. Sometimes, I get a flashing "?" on a file folder.  In my view, this indicates that the computer cannot find a bootable disc. I've tried resetting the PRAM, but I do not have the sound of the double ring that I was expecting.

  Once a Mac is longer than 4 years, his PRAM Battery should replace before resetting the PRAM actually works.

  Is this USB Flash drive "slipstreamed.  It works on any other older than 10.10.5 Mac?

  What is a copy from another Mac or Mac Mini itself 10.10.5 clone?

  Plug you directly into the USB port of the Mac Mini, or using a hub which is powered wall?

• Portege A100 PPA10A - update the BIOS to boot from a USB device

  Hello

  I have an old Portege A100, model: PPA10A-0002LP, but I can't seem to find this model on any Web site of Toshiba, closest I've seen is the "PPA10A - 0002 L'.

  I am wanting to know if there is a BIOS update that will allow me to boot from a USB device.

  The question I have is that I need to reinstall Windows, but the CD ROm cannot read disks.
  This network PXE boot, but I'm new to this sort of thing and have absolutely no idea what to do here.

  Any help would be great,

  Thank you

  Hello

  Portege A100 seems to be developed solely for the Australian market.
  As you say it is a model number Portege A100 PPA10A - 0002L listed on the Australian page of Toshiba Portege A100 PPA10A-0002LP belongs to the same series which is PPA10A
  So in my opinion, the BIOS should work too.

  Anyway, I doubt that the BIOS update will add boot options.

  Usually the BIOS supports booting from CD/DVD drive, drive HARD, LAN and USB FDD.
  It should be possible to boot from a boot disk using a USB FDD drive.
  I doubt you'd be able to boot from USB WEIRD since this Portege A100 supports an internal CD/DVD drive.

• Satellite M40 - 244--> Boot from a USB

  Hi all

  I have a Satellite m40-244 with a DVD player which unfortunately is out of service.

  I would like to know if it is possible to boot from a USB key to reinstall Windows or Linux. In the BIOS there only HDD, floppy, CD-ROM, and LAN drive options.

  Does anyone know how to boot from a USB? I tried an external USB DVD drive, it does not work. I don't know if I'm doing the right way.

  Thank you.

  Hello

  As far as I know that of not possible because the M40 BIOS does not support this!
  As you mentioned in your ad; There is only one option for booting from the HARD drive, ODD, LAN and USB FDD (floppy)

• Satellite U400-10j - how to boot from a USB flash drive?

  Hello

  I have a Toshiba Satellite U400-10j.

  I have Ubuntu on my USB flash drive, now I want to boot from it.

  I can't find the option in the BIOS to boot from the Usb flash drive.

  Second, I noticed that the phone also has an internal memory card reader.
  I could load Ubuntu top then to start the memory stick as well?

  Your help will be very appreciated.
  Thank you.

  I think that it s not able to boot from a USB key on this laptop.
  The best way is to use a CD. There, you can start on this notebook and all other laptops.
  In the Internet there are many versions of CD of Ubuntu and other Linux systems.

  And as said Feliks, it s not able to boot from an SD card because it is not in the BIOS.
