• 2481 - 3SG L530 - first 1.4 GB of RAM of 4 GB 'reserved by material' and now 2.2 GB? Problem BIOS/UEFI?

  Hello

  Using a Thinkpad L530, which becomes a few weeks over a year (-> warranty expired). Running Windows 7 64-bit on it (in BIOS compatibility mode).

  There is, at the same time (cannot say for sure) four months when I installed an update of the BIOS (which jumped several versions), then all of a sudden my resource monitor showed 1.4 GB of memory reserved by the hardware.

  I did some looking and also called the hotline of Lenovo Germany support (because they don't send support) because my unit was still in warranty, at this time, but useful guys might not help me get back memory - the conclusion was that for some reason, that the update of the BIOS must have changed how the integrated graphics card memory is managed intel (size is dynamic). Due to the fact that a downgrade to BIOS was impossible (due to some changes), they also offered to replace the motherboard with an older BIOS revision, but I refused (I have that it will not much help because I need to upgrade the BIOS later anyway, and really, I didn't miss my primary work machine).

  However, yesterday, after having done nothing more to try the different operating system a few live CD and certainly not after installing a new BIOS update or similar, sudden reserved hardware memory was 2.2 GB (I can say 100% certainty that Monday, it was not, since I was unable to resume a VirtualBox VM suspended Monday due to the change of configuration of memory - and to make sure I also was installing drivers) (or updates to the BIOS since Monday).

  So I'm now sure that this problem (and probably also the other I had before) was not caused by an upgrade of the BIOS or changes how Intel's integrated graphics is managed, but more likely a BIOS/Firmware bug.

  Also, the missing memory shows not only in Windows 7, but when I start a live Linux CD or at memtest86 boot.

  So I studied a bit and found out, that if I boot a Linux live CD (which support it) in UEFI mode (with CSM disabled legacy support), suddenly I can reuse many of my 4 GB of RAM. But only here, and I would use it on Windows and not by the re-installation of a license of Windows 8 in UEFI mode...

  Some information that I have collected (such as memory card EFI and card memory at the start of Windows and Linux, and Linux UEFI, screenshots of Windows) is available in this post in another forum: http://superuser.com/questions/746497/what-hardware-device-used-to-eat-up-1-4gb-of-my-4gb-ram-and-no...

  Does anyone have any suggestions

  -How do I know where this memory is gone?

  -Why memory cards so different between boot UEFI and BIOS/CSM

  -How to get the memory (without replacement)

  I heard of many problems UEFI (not only for Lenovo but also other suppliers) is caused by certain invalid EFI variables, is there a way to reset all variables of the EFI on my laptop (I am aware that I may have to reconfigure the boot settings later)? I tried flashing the BIOS (a version at the bottom and back again) and installation by default, or reset settings Secure Boot loading, but that did not help for my problem.

  
  

• Latest optional updates cause problem with UEFI system

  I had to restore my system from a backup because after you apply these updates optional, my system stopped and said that there was a change not allowed in BIOS or UEFI drivers.

  KB2952664

  KB3035583 Get Windows 10

  KB3133977

  KB3137061

  KB3138901

  KB3139923

  Anyone had the same experience and can identify which of these is the cause of the problem.

  For the moment I do not apply these updates.

  Hello

  We wish to inform you that after you install the update 3133977 on a Windows 7 x 64 system which includes a main focus on the ASUS card, the system does not start, and it generates a Secure Boot error on the ASUS BIOS screen. This problem occurs because ASUS has helped the motherboard turn on the secure boot process, even if Windows 7 does not support this feature.

  To resolve this issue, go to the following ASUS support site to find out how to disable Secure Boot for Windows 7:

  http://www.ASUS.com/support/FAQ/1016356/

  Note the Secure Boot feature is supported in Windows 10. To learn more about the benefits of security of this feature, as well as on the way to upgrade Windows 7 to 10 of Windows, go to the following Windows site:

  Hi guzhengand welcome to the VMware communities!

  You may need to use gBS--> LocateProtocol (...) to find an instance of EFI_CONSOLE_CONTROL_PROTOCOL and use it to change the mode of EfiConsoleControlScreenGraphics.  We are implementing our ConSplitter Console control protocol, and mode you get to start depends on the selected for the virtual machine guest OS type.

  The Console control protocol interface definition is not in the EDK2 code base, so if you use EDK2 you will need to track down the definition of interface yourself, which is pretty easy - go to your favorite search engine and look for "EFI_CONSOLE_CONTROL_PROTOCOL".

  See you soon,.

• ProBook 650 G1: Dualboot UEFI: automatic startup of windows

  Hello

  I have a problem dualbooting 10 Windows and Linux (Ubuntu). I did another partition on my hard disk to install Ubuntu on. I successfully installed Ubuntu and normally, it restarts and show me the GRUB bootloader, but it didn't.

  It starts directly in windows.

  I did a dualboot on this laptop before but then I had my motherboard replaced and now it does this.

  I can boot into Ubuntu by pressing F9: boot the device options and selecting Ubuntu. Can I get the GRUB bootloader. But this isn't what I want. I want that he let him start directly in GRUB, not windows.

  I also want to know how I manage my EFI partition. It is dotted with old. EFI files that are no longer relevant.

  Years the last issue: I can't boot into windows recovery mode by pressing F11 in the start menu. It just freezes.

  Help would be greatly appreciated!

  -Ximici

  @ximici: the following link provides information that should help you with your dual boot problem: install UEFI - tips

  The issue of the recovery, the OEM recovery is based on the original partitioning scheme remain intact.  Given that you have modified, installing Ubuntu, that "broke" the recovery feature.

  IF you want a way to restore the Win10 in its current state, so I recommend using a tool third-party imaging/restoration known as Macrium Reflect.

  Macrium reflect (MR) provides a FREE version that can be used to image and restore partitions or drives together.

  What I recommend is the following:
  (1) download and install Macrium reflect (MR)
  (2) run M. and choose the option: "Create an image of the partition (s) required to backup and restore Windows" to write a full backup to an external drive or USB key
  (3) use the option to create a CD or a USB startup key

  NOW, you have the means to restore a full system that works for the external hard drive or USB key in a few minutes.

  Good luck

• HP 15 r078tu: intel hd driver cannot install

  Tried to install the latest drivers from HP after clean install of windows 10 home, but it indicates an error in the middle of the installation "your computer does not meet the minimum requirements for installing the software.

But they do not function correctly, everytime I turn on my computer, the brightness controls do not work, but will work again after a reboot.

  My problem is now solved, reinstalled windows in legacy mode, works perfectly well, battery backup is better now. Thanks for trying to help me.  If anyone knows what was the problem in uefi mode, I would like to know if. Of the uefi boot is very fast comparison.

• [s205] How to install Win7 x 64 from scratch on a new hard drive?

  Hello

  I have a little problem to solve...

  I own a s205. My hard drive died. I replaced it with a new one. After that, I tried to install Win7 x 64. When installing, it created 2 small partitions. It was strange to me, I saw him for the first time. Later, I read that it is because of the UEFI.

  In any case, installed all good, but after installing the drivers, I have encountered some problems. Or net card worked. I started looking for information and I know that the problem is UEFI.

  My question - can someone write a guide how to install Win7 x 64 on s205 in traditional mode, so everything should work as before? Unfortunately I didn't save the DVD or any other source of images of Lenovos.

  Kind regards

• My Odyssey of upgrade of Windows 8

  Greetings.  I'm my upgrade of Windows 8 experience here in the hope that others can learn from the experience of logging.  If I am able to solve the problem here in these forums, I consider that a plus.  But above all, I am hoping to create documentation so that others can learn from this experience.

  Our story begins a long time ago, in a galaxy far, far away...

  No... not really.  I purchased a P7-1235 Pavilion in July and took advantage of promoting "$15 Windows 8 Pro Upgrade.

  Shortly after that Windows 8 has become available, I have installed the upgrade of Windows 8 tool, downloaded the upgrade files and decided to "create media install".  Now, call me old fashioned, but I thought that the best way to discover Windows 8 would be to perform a "clean installation."

  NOTE: My definition of the 'Clean Install' is a re - format the existing OS volume, or even a repartitioning of the main system disk, so that there is no remnanants of the previous operating system.  Aparently, after speaking with the support of Microsoft Windows 8 upgrade, we have a difference of opinion here.

  Now my Windows 8 upgrade path began with the start-up of the installation of the media and trying to do a custom installation.  I tried both the volume of BONE development in the form and also to delete the existing operating system partition.  None succeeded, that I learned that I could not perform the operation because the disc was GPT partitions.

  At this point, I had already backed up all my data and created the HP recovery discs, so I decided to delete all partitions on the disk.  One of these partitions, that I was about to delete included support UEFI.  But with all parttions now missing, I was now able to install Windows 8.

  After the installation is complete, I started working on creating additional partitions.  To my dismay, I didn't have the right to create more than 4 partitions.  The reason for this is because since I had deleted the UEFI system partition, my system had more support UEFI.  Without the support of UEFI, I had is no longer support for GPT partitions.  Without the GPT partitions, I had to use MBR partitions and so I could not have partitions of less than 2 TB in size (not a problem for this system with its 1 TB drive) and could not have 4 partitions per physical disk.

  After my system restore to factory settings (Windows 7 partition, Partition Recovery, UEFI system partition), I decided to enjoy the support of Windows 8 free Upgrade offered by Microsoft.  I decided to use the call return feature, and a few minutes on Sunday afternoon (my football team has been one week bye), I got a call back from a friendly Microsoft technical.

  First, the technician had carried me 8 Windows Update from inside of Windows 8.  She had chosen me for a 'Clean Install' option.  Being skeptical, I followed his instructions and completed the upgrade.  I saw the system afterwards, and it seems that there has been the backup the existing windows and directories Program Files and place them in a folder called "Windows.old".

  Then I explained to technicians how I thought should run a clean install, and she agreed to walk me through the installation by starting the system with the DVD of Windows 8.  We are moving through the installation process, and we arrive at the screen when it asks you where you want to perform the installation.  At this point, there are 4 listed partitions:

  (1) UEFI system partition

  (2) Windows 8 SYSTEM partition (of the previous update)

  (3) Windows 8 OS partition

  (4) HP recovery partition

  The technician told me everything first, try to install on the #3 partition.  Unsuccessful.  I get the 'Windows cannot install here.  It is a GPT partition.  Then, the technician was format partition #3 by using the "Advanced" on the screen of the installer options.  Unsuccessful.  Same error message.  Then, the technician had me open the format partition and the utility DISKPART #3.  Unsuccessful.  Same error message.  Finally, the technician had me run the FORMAT of the CLI command.  Unsuccessful.  Same error message.

  At this point, the technician tells me I have an encrypted drive and it cannot be upgraded to Windows 8, and I have to contact HP support.

  Go ahead. Go ahead... I'll leave this receiver.

  After falling off my chair, choose the phone back up and try to stay peacefully as possible, I told the technician that wasn't a) the drive encrypted, HP b) informed me that all Windows 8 upgrade problems have been handled my Microsoft and c) I thought we were dealing with a problem of UEFI/GPT support.

  At this point, my system is unusable.  I'm going to run system restore AGAIN to return to Windows 7 atleast both its usable.  Fortunately, before the technician has hung up, we agreed that it will worsen an engineer to LEVEL 2, and this engineer will call back me tomorrow night.

  I'll update this forum as and the Odyssey.  If someone saw on how to upgrade an HP Pavilion P7-1235 to Windows 8 Pro by doing a clean install and maintain support UEFI, I would really appreciate your insight.

  Problem solved. A big thanks to ramon2000 Windows 8 answers.microsoft.com forums.

  Is anyone else having problems with UEFI with the DVD ISO - Microsoft Community help

  Here are the instructions from ramon2000:

  We need to generate an ISO file, with two boot images.

  Boot images are available in the ISO file system.

  To build the ISO with the Microsoft tool "oscdimg.

  You can get the tool either by:

  one) to obtain the tool, or download the evaluation of Windows and the Deployment Kit (ADK) of download Windows Assessment and deployment (ADK) for Windows® Kit 8 official Microsoft Download Center
  or
  (b) simply download the conversion tool to a directory to Install Win8 a ISO in Thursday night

  Then you can mount the ISO file with a virtual DVD drive or insert the DVD into a real DVD player.

  In the following example, it is assumed that the Windows 8 DVD is in drive G:

  Now, create the ISO fixed (including the UEFI boot image) with the command (all in one line):

  Oscdimg.exe m-o-u2-udfver102-bootdata:2#p0,e,bG:\boot\etfsboot.com#pEF,e,bG:\efi\microsoft\boot\efisys.bin G:\ C:\path\to\new\win8pro-UEFI.ISO

  The utility creates a new ISO file.

  When the utility finishes complete creating the ISO file, burn the new ISO on a DVD file.

  When the computer restarts with the installation DVD with the help of UEFI in the DVD player, don't forget to activate your Start menu and select the drive in the list of terminals UEFI supported where it is not defined as the default boot option.

  Does not work too.
  I just need to put my .efi running in the starup
  Thank you all

  Hello
  Can you tell us what your problem is? I have seen a lot of technical stuff, but do not clearly understand your problem.
  If you are having problems to start Ubuntu in an Efi / UEFI environment I suggest you try copying the file to start the live-media / installation in your startup folder media.
  Please note that the suggestion is not detailed must apply little reason.

• Pavilion H8-1205eo: Problem with 980 Ti and UEFI

  Hello! A few years ago I upgraded from the Radeon 7570 standard to use a 670 gtx graphics card in my H8-1205eo and everything went well. Recently I bought gtx 980 Ti to run the latest games at high heat. When I started the pc after installing the card, that it would not go beyond the blue HP screen and pressing ESC to enter the BIOS would show only a black screen with my characteristics listed. After reading a little online, I came to the conclusion that I need to change legacy to UEFI. I looked around a bit in the configuration menu, but wasn't able to find a way to change this in the UEFI. Should I buy a new motherboard, or I simply do not found the setting?

  Peter, welcome to the forum.

  You can't find UEFI because the computer is equipped with a standard BIOS.  HP didn't start using UEFI until mid-October 2012.  There is no way to upgrade to UEFI.  The last series of video card that did not use UEFI was 640 gt.

• HID HW Radio with X1C UEFI 2.03 Lenovo driver problem

  I played a bit with WWAN today and noticed that the Device Manager does not recognize the device HID HW Radio. (LEN0078). The driver from the Windows 8 beta site is not correctly installed on my system. On versions of BIOS before 2.03 the device does not exist for Windows at all.

  Unfortunately I do not know that if the driver is properly installed before me noticing this, I found no trace in the registry well.

  Model is the ThinkPad X 1 carbon, firmware only to the definition in the UEFI, Windows 8 Pro x 64.

  I hope that this will be corrected in a future update, best regards.

  Well, just found out that this problem is corrected in the new driver output for GA you guys need to update driver pages more fast, seems that all pilots have signed on 24 September.

• T440s uefi boot problem

  Hello

  I recently bought a thinkpad T440s (bios version 2.27), I was able to boot xubuntu in legacy mode, but did not start using the uefi.

  As I do this is to grab the last amd64 iso xubuntu desktop, run isohybrid on it, finally "burn" on a USB.

  To start using the uefi, I tried many settings, with or without 'secure mode', none worked, tried on all usb ports, no luck.

  When Googling this problem, I found a lot of posts on dual boot with windows (which is for example in uefi mode),
  but I'm not concerned about dual-boot ubuntu will be my single operating system.

  I know on uefi help pages, but I find it hard to understand what is relevant or not in my case.
  I wonder if someone with close hardware, managed to install xubuntu (or another version) using the uefi.

  This post somebody would tell me how to proceed?

  Thanks in advance for your attention.

  Best account.

  Hello

  You have just taught me something about the iso images :-)

  I was finally able to start using the uefi, specifically, he started with the handling

  You told me (make a fat32 partition, copy the contents of the iso image on this score unique flash drive)

  but xubuntu is stuck the GUI front.

  I retried in raw by copying the iso image on the flash drive (dd if = of =....) without any other manipulations

  and it worked.

  Thanks for your help

• Z580 UEFI boot problem

  Hello everyone,

  I recently bought a Z580 (product number 59362732), provided without a pre-installed operating system. I installed a Crucial SSD (instead of the HARD drive) with success and replaced the DVD drive with disc HARD original.

  After installing Win7Pro and all drivers provided on the SSD (UEFI boot is set to on, SATA AHCI mode prior to installation) I am facing a strange startup problem - it seems not every time, but the laptop often just hangs after the Lenovo logo disappears and restarts itself and, as if he could not find the partition to boot from. However, in the configuration of the BIOS, everything seems normal - it recognizes both of my drives. This problem appears on the two UEFI on and off the start, but strangely, Windows starts without any problem after activating/deactivating the UEFI BIOS Configuration option - it doesn't matter if the activation or deactivation. I have searched for the solution on the Internet but haven't found any solution. Any help would be appreciated.

  Thank you, feki1409

  Hi Zoltan,

  Thanks for your advice in the first place! I tried to update the firmware, but it failed at some point during the installation. As I looked at the site of Crucial, the update is not guaranteed to work on UEFI/GPT disks, so I'll have to wait until the right driver is started.

  However, I tried to fix by using the EasyBCD utility startup files, as a friend advised me. The problem does not appear since then (4 start-up), so I hope that this is resolved for now. It was probably caused by my fault during the installation/system tweaking. I'll definitely keep you posted on this.

  Thanks again,

  feki1409
