• Dell Precision M4700 (Windows 7 pro) starts not once configured with UEFI and Secure Boot

  To all those who can help you:

  I got a Dell Precision M4700 and I update bios A05. I was intending to move to Windows 8. Everything was fine and the bios update was successful. I started the new bios under Windows 7 Professional (base OS) factory-installed and was very good.

  However, I can't get into the bios (not even see the POST from Dell or Logo) after I activate the UEFI and Secure Boot.This before I update to Windows 8 Pro. Now I'm stuck with a blank screen (same LCD not lit) and nothing to start. It's like a dead PC.

  Help, please. Is that what I can do or should I contact Dell Support for repair?

  Thank you

  I fixed it!  Just removed the CMOS battery, the BIOS got reset back to factory default.  So I did:

  (1) remove the battery

  (2) press the power button to the case of ground

  (3) remove the lower panel

  (4) disconnect the CMOS battery (it's tedious)

  (5) I hit the power button for some time (30 s) to clear the capacitors or something else, it was my theory, but I doubt it's necessary

  (6) use it to all back to the start

  When I turned it on it turns on and turns off several times before finally stay standing and I was then able to enter the BIOS and all the settings have been restored to factory default.  I am new to Windows 7 on my machine so I'll repeat the process, this time without disabling the legacy option roms!

  Here is the disassembly for precision M6700 and M4700 instruction manual if anyone needs:

  http://support.Dell.com/support/eDOCS/systems/wsm4700/en/OM/om_en.PDF

  I was talking about the Dell support problem and the guy said he would talk to his superior and see if something needs to be done, so I guess we'll see if something happens.

  I hope it works for you!

• Trouble with BIOS and secure boot

  Hello, I own a HP Pavilion 15-b040sl, born with Windows 8 Sleekbook and has been upgraded to 8.1. Now, I decided to downgrade to Windows 7 (I own a regular product key) and has done so successfully (I'm also using a Linux distribution in dual boot). The problem is since I've upgraded to 8.1 Windows, Secure Boot allows automatically when starting (it did not before upgrade, because I just Press esc - F9, then select "portable hard drive" boot selection, now I have to open the BIOS, enable Legacy Boot (and automatically disables the secure boot), then it boots correctly) , but I have to do this every time I turn on the computer. Is there a way to fix this? Simply, I need something to disable startup secure activation automatically at startup. Maybe an old BIOS update? I tried to take a look at downloading drivers, but I am unable to find the older versions.

  I finally solved this when I noticed there was an option to disable startup change requests. This option is selectable when you disable booting safe (without activating the legacy support). Thanks for help.

• VMware and Secure boot

  Good afternoon

  We use VMware vCenter Server 5.5.  While I see that in our virtual machines, we have the possibility of using the UEFI boot, I see no support for secure boot.  According to some articles I've read, I don't think that it is supported.  Here's my question:

  I have a virtual machine with installed Windows 8.1.  How can I start another device of this VM?  Windows 8.1 it locks.  I can access the BIOS or UEFI Manager, but I can't actually start to say an iso DVD.  It will not allow him.  But there is no option to turn it off.  How can we get around this if they need to start on another device?  Thank you.

  VMware virtual machines do not support Secure Boot at the moment.  It should not be possible for an operating system that is installed to "lock" the ability to boot from any other medium.  If our EFI implementation refuses to boot from a disk or an image, it probably means that the image/disk is not well-formed to start EFI support.

  What image/disc you're trying to start?  The same disc/image starts successfully in a VM EFI without an operating system installed?

  Some of the information and advice in this document for troubleshooting help: using EFI/UEFI firmware in a Machine virtual VMware

  See you soon,.

• Satellite P840: How to create the secure boot with UEFI Bios recovery disk

  Hello

  I have laptop P840 that came pre-installed with Windows 8, which I've upgraded to Windows 8 Pro.
  I then updated to Windows Pro 8.1 by Windows store. Please notify:

  1. how to create a DVD repair or start for windows 8.1 pro with UEFI Bios and boot secured.

  2. I created a USB recovery using the control panel in Windows Pro 8.1. It starts OK. It will be the same as that I've created using the Toshiba Media recovery creator or will it drivers Windows Pro 8.1?

  3. check partitions with disk management, then 3 (450MO, 350 MB and GB 10.90) recovery partitions, 1 EFI system partition and 2 primary (C: programs) and D: for data. I created the recovery DVD and USB 2 disks. Can I remove the 3 recovery partitions?

  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!

  > 2. I created a USB recovery using the control panel in Windows Pro 8.1. It starts OK. It will be the same as that I've created using the Toshiba Media recovery creator or will it drivers Windows Pro 8.1?

  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!

  > 3. Check it with disk management, then 3 (450MO, 350 MB and GB 10.90) recovery partitions, 1 EFI system partition and 2 partitions primary (C: programs) and D: for data. I created the recovery DVD and USB 2 disks. Can I remove the 3 recovery partitions?

  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

• Impossible to activate Secure boot of windows 8

  Hi, I can't get a secure start to activate on my computer, the option is grayed out in the bios

  Hi Jcwisgod,

  That's right, that a secure boot does not load the usb drivers, then connect a usb keyboard, when using secure boot will not work.   I don't know if you can activate the loading of traditional USB drivers and still have secure startup, you should test.

  If you can enable loading the usb and secure boot drivers would let me know for future reference.

  Win7 can't Secure Boot.

• Cannot boot from CD - DVD in LEGACY mode - NO Secure Boot UEFI NOT

  You just bought an Optiplex 7010 minitower with Win 8 Pro 64 - bit, 8 GB of RAM, 500 GB HDD and an Intel i5 processor 3470.  Now he has BIOS version A16.

  It is normally ON UEFI and Secure Boot on IT and F12 at startup does NOT normally display the CD-DVD as a boot option.  OK - no problem.

  However, if I reboot with F12 and select UEFI OFF (meaning WE legacy) and Secure Boot SHUTDOWN and reboot, then F12 DON'T show me the CD - DVD as a startup option, but if I actually try to boot from a bootable CD, I get an error message.

  I practiced with two CD bootable - a Knoppix I did on a XP machine an Aomei Backupper I did on a Win 7 machine.  These CD working as in my old XP machine boot CD, and the CD of Backupper of Aomei worked someone else machine Win 7 Pro 64 bit.

  What's wrong?

  Again, please let me repeat that I am trying to boot from the CD-DVD AFTER I have turned OFF UEFI, turned on the legacy and off Secure Boot.

  Thank you.

  Speed - although you predicted, I am amazed at what I did today.

  I bought a second hard drive (in white) and installed Win 7 Pro 64 - bit SP1 on it.  (I unplugged the first hard drive which has my Win 8 Pro 64-bit.  (Later to figure out how to dual-boot - no not yet for that.)

  What struck me is that I have installed SP1 for Win 7 Pro 64-bit while my BIOS is UEFI - it's ON UEFI and Secure Boot off.  (Enable Legacy ROM is enabled.)  BIOS is the Windows Boot Manager.  The Win 7 Pro 64 - bit SP1 DVD ran perfectly on my CD - DVD unit - no problems of any kind.  The machine has restarted several times, as I adjusted it settings and added the resource of Dell Media CD drivers.

  Disk Management displays only two partitions - a little with the legend "Healthy (EFI System Partition)" and then my C:\ drive, which is indicated be NTFS and 'in good condition (boot, Page File, crash dump, primary Partition).  The properties for the entire drive 0 said "Partition Style: GUID Partition Table (GPT).

  Now - is it good or bad?  If one day I try to dual-boot, what is incompatible with the four partitions on my hard drive to win 8 (now offline)?  Install this fake Win 7?

  I'm even more amazed than the Win 7 Pro 64 - bit auto installed SP1 with a product key that is different from the product key for my Win 8 Pro 64-bit.  The Dell OEM Windows 7 installation disc done by himself - I don't have to enter anything.  Which is good news for a future dual-boot, Yes?

  I have NOT yet connected to the internet.

  Now, when I unplugged my hard drive of origin WIn 8, I disconnected the Sata data cable and used for the new hard drive Win 7 added.  If the new hard drive is connected to data SATA motherboard even as the drive of origin 8 Win.  Well, at some point when I use two hard drives, one of them should be connected to another plug SATA on the MB - but not yet.

  Well... How do I fortunately to this stage so far?

• Qosmio X 870 and Windows update 8.1 - secure-Boot is not configured correctly

  After update of windows 8 for windows 8.1 a watermark appeared in the dekstop who says:
  + Windows 8.1 secure Boot is not configured correctly build 9600. +

  Is something wrong with the installation of the update?

  Thank you much in advance.

  I have a Qosmio x-870.

  If you see a message "Secure startup is not configured properly" in the lower right corner of the office, this means that Secure Boot is off or has not been configured correctly on the PC.

  Secure boot can be enabled or disabled in the BIOS.
  You need to access the BIOS and should allow secure boot.
  Save the changes and restart the device.

• V3 - 771g S8 i7. V2.28 BIOS how to disable secure boot mode and allow to boot from usb/dvd

  Hi people,

  Recently my laptop w8 shared with my brother get sick. So I decided to get out the trusty old diagnosis

  USB and dvd, you know, ubcd centos ophrack. Much to my dismay, I couldn't start any of them. So after some faffing

  everything on the net, I was able to boot/secure boot / disabled, which meant I could f12 at startup in the Boot Manager.

  Unfortunately, the drama is over. Kindly listed boot manager internal hard drive, but not bootable usb or dvd connected.  so I thought, I'm going to be cunning and change the boot order of start. Yet once the monster of Bios Acer jeeringly laughed at my attempts to

  take control of the material, I dared try control simply because I happened to pay a substantial amount of money to acer.

  So, it seems, the only option I have left to change is boot/boot mode / (boot uefi/legacy). So what I need to change to restore the boot control, is to change legacy BIOS uefi? Who will install the w8 cack?

  Also what happens if I want to replace the hard drive with an ssd in the near future, is not not to work?

  Oh, I tried to get help from the enamel of acer, their response said essentially bios/uefi is isn't a problem acer because it is sw and realized

  What seemed like a pay per minute service.

  Skills of good customer Acer.

  Any help appreciated,

  Hello..

• I hate the secure boot and a permament legacy boot startup sequence.

  I'm a new 700-074 8.1 running office.

  I have a Pavilion old Pentium 7-year-old who was running out of steam with new programs requiring a 64 bit OS and more memory.

  So, I got the urge.

  I like the image of the entire disk to an external drive once a month via a USB connection through a USB 3.0 adapter.

  I like the 2014 Acronis True Image program.

  The program may take a bootable cd, or it can be installed in the computer.

  When run in the computer, the computer must restart once the program installs a startup program.

  After I did it, the computer went to a black screen and wouldn't start. Had to call HP.

  I removed the program and decided to use the bootable cd.

  Don't see the cd because of the secure boot.

  With the help of HP, I was able to go into the legacy boot and download Acronis to run but he warned me that my target reader wouldn't start because it has been formatted to MBR and not GBT.

  So I reformatted the external drive at GBT but it seems to reboot the computer is returned to the secure boot.

  On my flag, I have had trying to start first on the cd drive and then automatically try the first hard drive of the computer.

  I seems that legacy boot can start only once on a single device before returning on secure boot.

  Is there a way to keep the computer in legacy mode and try in order the cd drive then the hard drive?

  When you ACTIVATED 'Legacy Support' is not disable "UEFI". Peripheral boot UEFI still have priority and will start as such. The cloned drive should start just fine, as long as the UEFI / GPT boot structure remained intact on the clone.

  If you have any other questions, feel free to ask.

• Secure boot requires firmware which supports UEFI followed the v2.3.1 Errata B and has the authority of Certification Microsoft Windows in the base of signatures UEFI

I want to upgrade to Windows 8 and it's what came when I bought the program online "secure boot requires firmware which supports UEFI followed v2.3.1 Errata B and has the authority of Certification Microsoft Windows in the UEFI signatures database... Thøis means that my laptop is not compatible? is there something I can do to fix it so I can get windows 8?

  Secure boot is a protocol feature not a Windows 8 of UEFI recent incidents made of PC/Laptop, etc. This is a feature implemented in the BIOS of a PC/laptop.

  Old PC do not have this in the setup of the BIOS, so it cannot be used.

  You have been informed that Secure Boot is not part of the BIOS, you may not use the feature.

  No have Secure Boot will not in any way affect the installation / execution of the W8.

  Here's a technical explanation of Secure Boot, read if you like:

• Can't get running dual boot Linux (Fedora) and Win8.1 in UEFI Duo 11 & secure boot mode

  Hello people,

  last year, I bought a 11 (Intel i5, 1.8 MHz, 8 GB RAM, 128 GB SSD) Duo with Win8 (64-bit) installed in secure boot mode. December 2013 I updated the OS 8.1 with a new license and curled UEFI & secure mode active, a few days after I installed Fedora 20 64-bit.

  Installing linux running properly, but I don't get any what startup, or UEFI GRUB menu and only earn 8.1 starts automatically. I checked the EFI partition: all files are installed in the appropriate directories.

  Can someone help me get the dual boot running?

  Thanks in advance

  Michael Wachs

  Hello again,
  Mission accomplished, I have a dual boot win8/fedora20.

  Well, it was much more difficult than expected.

  First of all, thanks to this guy, it's a bit more clearly how noncompliant efi bios on vaio actually works:

  so, let's keep in mind that the start process seems to:
  Look in /EFI/Microsoft/Boot/bootmgfw.efi; If present, it starts.
  Search in all subdirectories of /EFI/ for grubx64.efi. If present, it starts.
  Start /EFI/Boot/bootx64.efi
  Displays an error such as "The OS not found" message.

  Now, that's how I managed to do so, please note that:

  • It's more a hack here-I-fixed-it rather than a clean solution, but it works
  • There is probably a more easy/better way to do
  • a step may be unnecessary (I will say that when I suspect, but I will definitely not return to test)
  • I'm Italian and my English is awkward

  (1) enter the bios settings, select the boot from cd/dvd and disable secure boot (this may be unnecessary and can be re-enabled at the end of the process, I don't really know at the moment)

  (2) use the Fedora dvd installation (NOT 'live' one since you will need the feature of 'rescue') (Finally, you can use a direct to start and then go up and chroot for installed partitions, but it is longer)

  (3) save the system installed, this should mean pressing enter three times and ending up in a shell

  (4) if all goes well, run:

  chroot /mnt/sysimage
  

  (5) go to/boot/efi/EFI and follow these steps

  mv Boot Boot.old
  mv fedora Boot
  cp Boot/grubx64.efi Boot/bootx64.efi
  mv Microsoft/Boot/fwbootmgr.efi Microsoft/Boot/bootmgfwFUBAR.efi
  

  Now, this way our graceful bios not compliant will not find Microsoft file and will head to Boot/boot64.efi (fedora one). Unfortunately, grub scripts does not detect windows, so we need to manually add Windows entry in grub conf.

  (6) take note of the UID of the EFI partition:

  grep /boot/efi /etc/fstab
  

  (Well Yes, there are safer ways)

  (7) edit /etc/grub.d/40_custom and add this:

  menuentry "Windows 8" {
  insmod part_gpt
  insmod fat
  insmod search_fs_uuid
  insmod chain
  search --fs-uuid --no-floppy --set=root A609-3B1E
  chainloader (${root})/efi/Microsoft/Boot/bootmgfwFUBAR.efi
  }
  

  (8) now we will (re) making our new config (in our new location):

  grub2-mkconfig -o /boot/efi/EFI/Boot/grub.cfg
  

  I fear that this step will be necessary whenever there is an update to the kernel

  9) restart with fingers crossed

  Oh, I currently have a working dual boot windows 8 / 20 on my vaio fedora.

  My biggest fear this time, it's some obscure windows update could restore the original Microsoft/Boot/fwbootmgr.efi. Finally, I could rename it again, still, it would be boring. We'll see.

  What a great way to spend a Saturday morning.
