• 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

  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.

• Aurora R4, 8.1, NVIDIA GTX 690, UEFI, Secure Boot Windows

  I have an Aurora R4 that came with a NVIDIA GTX 690.  When Dell will release a video for the GTX 690 ROM update so that Secure Boot works under Windows 8 and Windows 8.1?  ASUS, EVGA and several other vendors of this map published a videocard ROM updates already that allow this work.

  It's been a year since it became a problem with Windows 8, and now Windows 8.1 he remarked with a watermark on the screen that says: "secure boot is not configured correctly.

  The video card shows a subprovider from NVIDIA, but NVIDIA does not seem to make these updates available ROM, as it is to the card suppliers like Dell to do.

  Today, Dell replaced my NVIDIA GTX-690, as well as my motherboard and memory under warranty (wouldn't boot after the home screen Alienware - F2, F12 did nothing).

  Now I am finally able to activate Secure Boot, like the GTX-690, they sent has a compatible UEFI BIOS, whereas one that I got with my new Aurora-R4 does not.

  For reference, the new NVIDIA GTX-690 has the video BIOS version: 80.04.1E.00.1F.  And work with Secure Boot.

• Aspire R disable secure boot

  My VPN provider requires the version 5 Cisco VPN Client.  The VPN client installs a unsigned kernel mode driver.  The UEFI boot system uses Secure Boot, requiring signed kernel-mode drivers.

  When I go through the initialization (non secure/non-UEFI) legacy, she prays for a USB dongle, I did not.

  What should I do to start inherited from the SSD hard drive?

  After I have legacy-boot, I need the old acer drivers?  Those who?  Where can I download them?

  After I have legacy-boot, I need to reinstall soundcards 10?  How the hell can I do that?

  Any help would be greatly appreciated.

  If you just need to install an unsigned driver, you don't need legacy or disable startup secure; Just disable windows application signed drivers.

• Dell M6700 Nvidia Quadro K4000M No. after Secure Boot screen

  Hello

  M6700 doesnot show anything on the screen.

  Here's what I did:

  Windows 10 in UEFI enabled and active Legacy ROM installed.

  After installation, start secure.

  White screen now.

  I tried to reset by removing the CMOS battery. no luck

  Need help.

  Thank you.

  So, I managed to solve the problem.

  There are problems with K4000m running on secure startup. You should not disable legacy boot rom.

  If you have no display at all here is a painful solution.

  Make sure that you can open Notepad and back again together. (Use an anti-static tape etc.). don't forget the screws and etc. locations consult a manual or take it to a technician.

  So, you will have the top open the portable whole. remove the graphics card, remove the screen connectors and connect the laptop to an external monitor via a d - sub (VGA) port. You now have a view. Go to the BIOS and disable secure boot and activate the legacy boot ROM

  Replace the graphics card and everything is back in place.

  Recommended BIOS: A15, is still not secure boot using.

  I think that the K4000m was not a boot rom EFI. So therefore no display.

  Hope this helps anyone having the same problem.

• 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.

  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?

  > 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!

  > 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!

  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

• Environment support UEFI HP or environment Support HP Unified Extensible Firmware Interface (UEFI)

  You have a question. I have a laptop HP 2000-2b19wm. I bought this system. It came with Windows 8. After I got it I have completely got rid of Windows 8 and IMHO set level to Windows 7 Ultimate. I deleted all partitions and let 7 configure the hard disk the way he wanted, got the drivers and so on and so forth. (not worried about security, I can handel most hardware repairs and software patches).

  I looked to see if there was a new BIOS available and there was, however, I also noticed that there are two things called environment support UEFI HP and HP Unified Extensible Firmware Interface (UEFI) Support environment. I know they have to with the Diagnostics and recovery of a bad BIOS flash.

  The question is this. Install HP UEFI Support Environment or environment Support HP Unified Extensible Firmware Interface (UEFI)?

  Thank you.

  Hi @bfldworker ,

  Thank you for your query.

  UEFI is preinstalled on your laptop.  It does not reside on the hard drive, so when you have formatted and installed Windows 7, it should not affect it.

  If you want to check this press the "F2" key shorten once every second on startup (before Windows loads) and he has to show the menu.

  I hope that this has answered your concerns.

  I am concerned about the impact that could have on the UEFI firmware / signatures Secure Boot on the PC.

  Do I need a HD HD (or PC) manufacturer signed device driver?

  Or the complete reinstallation of the W8 Pro will receive the drivers that I need to keep Secure Boot working properly?

• 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?

• 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:

  I hope it works for you!
