B570 - Booting in Legacy-BIOS-Mode (without UEFI)??

hi folks,
do you know how to boot a dvd in legacy-mode (without UEFI)?
my lenovo B570 UEFI has very little options, so i assume the other options (e.g. booting in legacy mode) are hidden somewhere.
i also found a guide from lenovo for the thinkpad series, but the option (see step 3) clearly is missing with my notebook.
any ideas??
thank you very much in advance..

Hi,
i got my new T420 in may this year. As I am a student i get the new Windows 8 out of Dreamspark one month ago. Before I installed Windows 8 x64 I made all bios and firmware updates i can get. 
After the successfull installation I got some startup hangs, not regular, but most of the boots. A few days ago a new bios was available, so I hope this one will get me rid of the problem. But the same thing happens, well I think it is the powermanagement, because the hang always happens at this point, when the display is going to dim. If I have the power plugged in, I don't get this problem. 
Hope this will be fixed in later versions of bios / powermanagement.
Best Regards

  • S205 & Win8 - How to force legacy BIOS mode?

    Hi,
    as far as I know the S205 has got two different interfaces:
    UEFI and legacy BIOS.
    Windows 8 supports both.
    Using UEFI, Windows will partition the drive with GPT.
    Using BIOS, it will be done with MBR.
    The main problem is that - probably due to malfunctioning drivers - there are some major problems when using GPT with this netbook. You can find numerous threads about not working WiFi cards for instance.
    What I'm looking for is an option to boot the Windows 8 installation through the BIOS interface from a thumb drive.
    The S205 hasn't got an optical drive and I haven't got one either.
    Thanks in advance for any help.
    PS: As this is not a driver issue, I'm not posting this in the Windows 8 forum.
    Solved!
    Go to Solution.

    After doing some research, this is how to successfully use the Ralink Wifi with Windows 8 on the s205 - clean USB install.
    You must install Windows 8 in legacy mode (choose "IDE" in the BIOS).
    BUT - you must *also* remove "bootmgr.efi" and \efi\ from the USB, before you install. If you don't, the USB will still install in EFI!
    If you already installed Windows 8 in IDE mode from USB, you must check if your install is IDE/legacy or EFI - open this log file:
    \Windows\Panther\setupact.log
    Look for this text:
    Callback_BootEnvironmentDetect: Detected boot environment: BIOS
    =you have IDE/legacy install
    ...or
    Callback_BootEnvironmentDetect: Detected boot environment: UEFI
    = you have EFI install
    (This information is from http://forums.bit-tech.net/showthread.php?t=209045)
    If you see EFI/UEFI in the log file, you must reinstall Windows 8.
    The only problem I have now is that Windows is freezing sometimes, so I plan to reinstall from a different USB in case of file corruption etc.
    Hope this helps.

  • T420s & Windows 8: startup problems in legacy bios mode (and workaround​)

    a heads up for anyone looking to install windows 8 on a t420s. after my inplace-upgrade from windows 7 to windows 8, the os would only boot every 10-15 tries. most of the time it was stuck on the blue windows bootloader logo.
    after being annoyed too much by this, i went ahead and manually converted the MBR to GPT with the help of gparted/gdisk . then i switched to UEFI-only mode in the bios and used a UEFI-enabled windows 8 boot stick to use the win 8 recovery tool to make the disk bootable again.
    since then, no more boot problems.
    TL;DR: if you plan a fresh installation of windows 8 x64, make sure to switch to UEFI only mode in bios before running setup.

  • Arch fails to boot after installation (BIOS mode)

    I finished my Arch installation, following the Beginner's Guide, and once I unmounted the partitions and rebooted, GRUB failed to boot into Arch. I'm not exactly sure what the problem is though. Basically what happens is I power on the machine, the Dell splash screen comes up, GRUB loads, I choose
    Arch Linux, with Linux core repo kernel
    the kernel and ramdisk attempt to load, then some message about "recovering journal" appears, and then I return back to the Dell splash screen. The same thing happens even if I choose the second option
    Arch Linux, with Linux core repo kernel (Fallback initramfs)
    However, when I choose to boot Win XP everything boots just fine. My apologies for the quality of the videos and pictures.
    Here's a video of what happens:
    http://youtu.be/uC96kX6iTjI
    I suspect this has to do with this error I got when I generated the "grub.cfg". Although I'm not entirely sure because my understanding is that this error would affect booting Win XP which in fact boots perfectly fine. 
    Error (and no I'm not using any lvm volumes)
    http://imgur.com/qqxpoGG
    I believe these are the portions of the "grub.cfg" that load Arch and Win XP. I got these by pressing "e" while on their menu entry in the GRUB bootloader.
    Arch (I had to scroll down to see the rest, hence two pictures)
    http://imgur.com/79dBw2C

    Any idea how I can fix this? Any help is greatly appreciated and please be patient, I know, I'm a noob.
    * I'm not sure if this is of any significance but I had a problem very similar to this when trying to get the Arch install to boot via usb (this computer doesn't have CD/DVD drive). I solved it by following this excerpt from the Beginner's Guide.
    Troubleshooting boot problems
    If you are using an Intel video chipset and the screen goes blank during the boot process, the problem is likely an issue with Kernel Mode Setting. A possible workaround may be achieved by rebooting and pressing
    e
    over the entry that you are trying to boot (i686 or x86_64). At the end of the string type
    nomodeset
    and press
    Enter
    Here's a video of what it looked like:
    http://youtu.be/vXRcbU0zdto
    The computer specs:
    OS: Windows XP Professional 32 bit Version 2002 Service Pack 3
    CPU: Intel Pentium 4 @ 3.00 GHz
    RAM: 2 GB DDR2
    HDD: 80 GB

    Hi,
    why did you not try adding nomodeset with the regular boot? During the net-install no video drivers will be installed;
    you have to install them after reboot after installing xorg. The (video)problem you had with booting from usb is still
    present.

  • Change the already installed Win 8.1 BIOS mode from Legacy to UEFI

    Hey,
    It seems that my Windows 8.1 is installed in BIOS mode: Legacy as "msinfo32.exe" shows. I can boot into it with no issue, but when I go to my laptop's BIOS settings and change the mode back to UEFI, it gives me an error "Operating system not
    found" (not sure about the exact error message).
    I am just wondering if it is possible to change the Windows 8.1 BIOS mode to UEFI so when I change the laptop's BIOS settings back to UEFI, it can boot into it?
    Regards.

    Hi Amin CiscoSoft,
    Since UEFI mode need an EFI system partition (ESP) which has the partition type ef00, usually contains a FAT32 file system. We need to recreate the partitions needed for booting the installation media in UEFI mode.
    Before you doing that we VERY recommended for you to read all contents including Prerequisites and warring paragraph in links below, then perform a backup of your data. If you have a second disk drive big enough, you can simply create a system image and
    able to recover the full installation as it was before you started this procedure if anything goes wrong.
    Since the steps are complicated, please follow the steps in

  • BIOS mode-UEFI or Legacy in Lenovo G580?

    I have lenovo g580. in bios setup under boot tab, it says UEFI boot 'Enabled'. but when i go to cmd and type 'msinfo32', it says my system has LEGACY bios mode. what actually is it? if i have UEFI mode enabled, why it shows legacy in msinfo32? please help........

    hi firozmkhatri,
    According to this FAQ, the UEFI BIOS has to emulate legacy BIOS so that existing applications aren't broken (this means 32bit programs since UEFI only works with 64bit versions of Windows). If you have UEFI enabled under BIOS and see it's saying Legacy under msinfo32, you probably have a Windows 7 system installed on legacy mode as the Lenovo G580 supports UEFI with an emulated Legacy.support.
    To check if you have Windows installed on UEFI (GPT) or Legacy mode (MBR), check your drive volume:
    1. Click Start, right-click Computer and then click Manage
    2. On the Computer Management window, choose Disk Managemment
    3. Right click on any of the Disk (i.e. Disk 1), choose Properties and on the Volumes tab, see Partition Style

  • Requesting legacy BIOS firmware for N750TI-2GD5TLP

    This may be different from most of the UEFI requests.  I have an older computer (supermicro X7QCE) that requires legacy BIOS support (or hybrid bios support) and also requires the low profile version of the card or I would have gotten the version with a switch between the two.
    SN: 602-V809-319SD1501091120
    As the motherboard shows no signs of recognizing the card, I can't easily retrieve the current bios version with my computer.  If it is absolutely needed for a downgrade to a legacy BIOS, I can use a friend's computer.  I thought I 'd check here first.
    There's no hardware problem with the PCIe slot as I'm using a zotac gt 740 right now, and no power restriction problems.
    I don't know the terminology that well as far as GOP or vBIOS, so sorry if Im using the terms incorrectly.

    Quote
    Actually, NM, I found the answer in another thread.  The switch explicitly switches between EFI mode and legacy BIOS mode.
    These are not just modes. The switch allows to use the card with a plain legacy vbios or a UEFI/GOP (hybrid) vbios.
    Quote
    As this is the case, I can come to no conclusion other than there is a problem in the EFI/legacy mode handoff in the vbios for essentially every other version of the gtx750ti.
    Like already said UEFI or legacy is not the only problem that can stop the card from working in an older computer but the support for later cards in general.
    Quote from: flobelix on 22-May-15, 17:46:07
    We don't know what "Supermicro" computer you have and what it works with since we are not Supermicro support. Legacy and UEFI mode or GOP compliance is not the only things that determine if a card runs in your machine. Newer cards must work at all on that older machine what is not guaranteed on oem machines that are very rarely updated. With latest gen vgas that is surely a problem and has nothing to do with the vga's vbios. Only Supermicro can tell you if current generation vgas are supported.
    Quote
    I guess if I want to get this card to work and not just return it, I'll have to hack the firmware.  Dont suppose there's any tools for making that any easier?
    Get used to the fact that the problem is not the card or it's vbios but your pc's oem mainboard and it's lacking support for newer cards. Else it would at least work with card switched to the legacy vbios.

  • Upgrading Windows 7 (Legacy BIOS/MBR Disk) to Windows 8 (UEFI/GPT/Secure Boot)

    Hi there,
    I've recently purchased a W530 with Windows 7 pre-installed.  Ultimately, I'd like to replace this with Window 8 + Secure Boot.  I believe I can get Windows 8 via the Microsoft Upgrade offer for a reasonable price, since this was a recent purchase.
    What's the best way to reach my goal?
    The Windows 7 install uses Legacy BIOS to boot with an MBR disk.
    I had a quick look at Acronis, and I can see that it's possible that the "OS will be automatically converted to support UEFI booting" (http://www.acronis.com/support/documentation/ABR11/index.html#14021.html) when using it's tool.
    If I don't use this approach, what can I do?  Can I:
    1. Use Rescue and Recovery in Windows 7 (Legacy BIOS/MBR disk)
    2. Wipe the drive and reformat it with GPT?
    3. Install Windows 7 with UEFI enabled using the Rescue and Recovery made in step 1?
    4. At this point, I would now have UEFI and GPT.
    5. Perform an Upgrade from Windows 7 to Windows 8 and enable Secure Boot?
    Any thoughts as to whether this would work?
    Richard.

    Hi richii,
    The Acronis approach ends up in failure. Didn't give it a second look at the reason, since the tool it's not necessary. I also tried several other "automatic" tools without success.
    The recovery approach will fail because it's tied up to BIOS boot.
    But I've performed the conversion from BIOS to UEFI two times successfully. After some digging, is not SO hard. It's just... "undocumented". Very, very undocumented, hehe. I made a step-by-step guide: http://social.technet.microsoft.com/wiki/contents/articles/14286.converting-windows-bios-installatio...
    Let me know if it helps you...
    Anyway, if you don't have data/software, I would go for the clean install approach.
    Cheers.
    If I helped you, please give me some kudos! ^^

  • Request MSI GX640 UEFI boot bios mod

    Hello I was wondering if someone could help me re-enable the UEFI Boot option in the latest MSI GX640 bios version E1656IMS.10F
    Also is it possible to add SSD support in AHCI mode as well, because currently I can not get an ssd to boot in that mode. It only works in IDE mode for some reason.
    I would also like it to be fully unlocked.
    Thank you!

    Alright cool. The reason I asked about the UEFI Boot feature is because it was enabled in the original BIOS, but they disabled the feature in a BIOS update because when the feature was enabled it would cause the system to hang when booting from a CD/DVD.
    I bought this Dell AMD HD 7970m GPU for my GX640 and I found out that it is a UEFI card that doesn't have a legacy vBIOS, and after I installed it, my laptop would not post and I got a black screen. I was thinking that if I had that UEFI Boot feature back, then my computer would boot with the GPU installed in it. Please correct me if I am wrong, and please let me know if some sort of BIOS mod would make this GPU work in my GX640.

  • Cannot Access BIOS or Boot Windows 8 After Changing UEFI BIOS to Legacy BIOS

    Acer V7-751, 500G HD, Windows 8.
    I changed the BIOS settings from UEFI to Legacy BIOS when I was working on a problem. Now I can't even get into the BIOS (F2)
    or change the Boot Order (F12). All I get is an error "Operating System not found". I can boot with a Win7, Win8, or Win8,1 DVD. I suppose I could boot with just about anything else bootable as well.
    The problem seems to be caused because it's set to Legacy BIOS and Secure Boot Manager as default #1 boot device. Legacy BIOS
    can't boot a Win8 drive that has been installed under UEFI (Secure Boot). I have to change the BIOS back to EUFI to boot the WIn8 drive, but the only way to change the BIOS is from within Win8. It's a very flawed way of doing things but it's the way it is.
    Does anyone have any suggestions that they KNOW work. Please don't Google answers. I've already done that. And please (please)
    don't tell me to power on and press "F2" (or any other key) to go into BIOS. If I could do that I wouldn't be posting.
    Once again, I cannot get into the BIOS without going into Windows first. I cannot load Windows because the install was done
    under UEFI. I cannot change from Legacy to UEFI because I can't get into the BIOS.

    In this case, I flashed the BIOS with a newer version of the BIOS/Firmware and that returned everything to the Defaults (not Legacy BIOS). I believe you could also flash with the same version. I don't think you could flash with an earlier version, but no harm
    in trying it. if you've flashed the BIOS previously, you may be able to restore the previous copy. It all depends on the manufacturer and how they handle flashing the BIOS.
    I wasn't able to, but you may also be able to boot from a correctly formatted USB drive with another OS (Windows XP/Vista/7) because Legacy BIOS allows you to boot from external devices. Essentially, you need to be able to boot from a valid OS that is not on
    the Hard Drive that was configured using the UEFI BIOS setting.
    Please let me know if you have any more questions, and I'll do what I can to help. If this solves your problem, please mark my post as the answer. Thank you.

  • Prepare an usb thumb drive, to boot windows 7 or 8 in UEFI mode

    Purpose of this post:
    Prepare an usb thumb drive, to boot windows 7 in UEFI mode and install the system in pure UEFI mode.
    Why am I writing this:
    I had a hard time finding out how to make a custom installation of windows 7 in pure UEFI mode, and avoid using the factory restore disks. After hours of research, experiments etc I finally got the point and found a solution. And I'm happy to share my research with you. I hope this will be of help. If something is not clear, or more information is needed, I will be glad to explain things further.
    History:
    As most of you already know, BIOS was developed for PC in early eighties and has remained unchanged in recent years. But, since 2000, Intel started working on a new firmware interface, called Extensible Firmware Interface, abbreviated EFI. And since 2005 United EFI Forum has been handling the responsibility for development, management and promotion of UEFI specifications. Bigger companies like Intel, AMD, Microsoft and Dell have already started to bring out their products in accordance to UEFI standards which has more stable, secure and easier to use interface.
    How does UEFI works (in a nutshell):
    Once you power on the UEFI based PC, the Pre-EFI is executed which initializes only the CPU, memory and the chipset. This followed by Driver Execution Environment (DEX) where other hardware is initialized.
    Advantages of UEFI:
        It can integrate various drivers this will not require to load during booting so saves time.
        PC can connect to network without OS.
        Also integrated drivers allow rendering GUI based control panel which out dates the old school bluish BIOS screen.
        Not all the installed hard drives are scanned as boot drive is set during the installation of OS in UFFI.
        Applications like anti-virus and diagnostic tools can be stored on virtually any non-volatile storage devices attached to a PC.
    For a system to boot and install in UEFI the partition table of the HDD should be GPT (GUID Partition Table), not the old school MBR (master boot record). GPT has many advantages, can have virtually an unlimited number of partitions (windows will allow only 128) and impressively big partitions.
    Since UEFI has a lot of advantages why not having a system install and boot in UEFI mode? AFAIK new Lenovo notebooks/netbooks are UEFI capable and OS’s are already installed in pure UEFI mode.
    So, let’s go now to the point. Do you want to have more control over your HDD? Let say, you have a 320GB HDD and you have divided it in two partitions, one of 50GB, for your Windows 7, and the remaining for your data. If something goes wrong and you need to restore your system to factory default, with the recovery disks, it will wipe your partition scheme, set the system to default and this way your data will be lost.
    You may want to make a “vanilla” installation of windows from a USB thumb drive and avoid using factory recovery disks. Now here things get complicated. A standard preparation of the USB with Microsoft’s software (Windows 7 USB/DVD Download Tool), or other tools, will give you a bios installation, not a UEFI one. So for the system to boot, you will need to change some settings in bios, and changing it from UEFI to legacy bios. The installation will prepare the HDD in MBR partition table, and you will lose all the advantages of UEFI, described above.
    Now this can be avoided, by properly preparing an USB to boot and install in UEFI mode. Here are the steps:
    Step by step tutorial:
    1.    In a windows computer, download a legal copy (although trial) of the windows 7 os. You can do this from here: http://www.mydigitallife.info/official-windows-7-sp1-iso-from-digital-river/
    Be sure to download the same version that came preinstalled in your computer. For example, if you have a Lenovo x120e, with a Windows 7 professional, 64bit, download an iso image of the Windows 7 professional 64bit.
    2.    Once downloaded burn the iso to a USB thumb (at least 4GB) using Windows 7 USB/DVD Download Tool.
    3.    After preparing this, create a folder on your computer, name it whatever (i.e. W7pro64bit). Go to the root of your USB
    and select all the files and folders there (9 in total) copy, and paste to your folder you created, W7pro64bit.
    4.    Using windows format the usb again in FAT32. Windows 7 USB/DVD Download tool, formats it in NTFS. We need a FAT32 formatted disk to achieve our goal. Formating again the USB in FAT32 will not touch the MBR of the USB thumbdrive. And after copying back the files (see step 6) the USB will still be bootable. (nice, and simple, isn't it?)
    5.    Now go to the folder W7pro64bit and do the following:
    a.    Browse to W7pro64bit\sources\ and open install.wim file. It’s a big file, and can be opened as an archive with 7zip (free software). Do not extract it, do not modify it, just browse the file with 7zip. Just to be sure you do not mess with that file, you can copy it somewhere else in your computer, and than procede.
    b.    Browse this file (install.wim) to \1\Windows\Boot\EFI\ and locate the file bootmgfw.efi. Do not move, delete it, but just drag that file to the desktop. (if you have copied the file install.wim to another place in your computer, than you are safely do whatever you want with that file ) Close the 7zip program to release the install.wim file.
    c.    Rename the file you just copied to the desktop from bootmgfw.efi to bootx64.efi.
    d.    Now go back to w7pro64bit folder and browse \efi\Microsoft. Form there copy the folder boot and paste it one level up, on the folder: \efi. It will look like this: \efi\boot.
    e.    Now copy the file you saved on your desktop and renamed (bootx64.efi) to \efi\boot (inside the boot folder you copied on step 5d
    6.    Now go to the root of the folder W7pro64bit and select all folders and files (9 in total) copy, and paste all those files back to your USB thumb drive. (see step 4 for more info)
    7.    Go to the computer that you are going to reinstall, and before restarting it, use the program ABR (activation backup and restore) to backup the license of your windows os. (use google to find ABR). Advanced Tokens Manager (ATM ) is great too. This link may be of help: Backup and restore W7 activation. After the program finishes its magic, it will create a few files inside the folder where the program itself reside. Copy these files to a new folder in your usb.  Rename it to ABR so you will quickly find it later. (if you decide to use ATM, the procedure may be a little different. But you are smart enough to figure out how to use it)
    8.    Backup to an external storage all your data before continuing.(reminder: are you sure you saved the license as explained in step 7, to a safe place? To a external drive, to another computer? If you are sure, than go on with step 9)
    9.    Now restart your laptop, and enter your bios settings. Go to the boot settings, and set the computer to boot in UEFI only. Not both, not UEFI first, or legacy, BUT UEFI only. Save and restart.
    10.    Press f12 (or the corresponding key for your machine) to choose the boot device and chose to start from the USB thumb drive with your windows 7 pro 64 bit.
    11.    If everything is done correctly, your computer will boot from the USB.
    12.    Follow the wizard and choose a custom install, not upgrade. At the disk partition window delete all the partition you see there until you have only one unallocated space.
    13.    Select it, and click next to install windows, without making partition in this point. The installer will create a GPT partition table not a MBR since the USB booted in UEFI mode.
    14.    Immediately after the first restart remove your USB thumb, and the installation will continue from the HDD. Wait until installation finishes.
    15.    When you will be finally on your desktop, on the installed OS plug your USB go to the ABR folder and click on restore.exe. It will restore your license and your copy of windows will be activated.
    16.    Now you can go in computer management/disk management and shrink the HDD to create your partitioning scheme. Make sure to leave enough space to your windows os. (30gb or more for extra programs you will install at your choice)
    17.      Download from lenovo.com thinkvantage system update and update your system. Windows update too can install all the necessary drivers, if you need only  basic drivers support.
    Note: if tvsu will fail to work, see this:
    http://forums.lenovo.com/t5/ThinkVantage-Technologies/ThinkVantage-System-Update-Servers-down-the-wh...
    It may look a looong tutorial, but once you do this for the first time, it will look a piece of cake.
    Final words:
    From now on, you can install windows 7 in UEFI mode with your special USB without changing your partition scheme anymore. If you have a data partition beside your os partition (see the example above), when you reinstall the system using your USB thumb drive, at the disk partition window chose the partition where windows is installed, delete it, and reinstall windows to the unformatted area. Your partition with your data will be intact and the installation will automatically mount your data partition to the system. And, all the scope of this procedure, you will always have a pure UEFI installation of the system, with all its benefits.
    Have fun!

    Thank you, as I noted here, your post was the key to my getting a Windows 8 SecureBooting setup on a W530.
    In the case of Windows 8, I needed to copy the files away, reformat my USB key as FAT32 and copy the files back, and viola I was able to boot from my USB install media with the BIOS set to only boot UEFI.  From there, there rest was easy (for Windows 8, the copying and renaming is not necessary, the key is having a FAT32 partition on the USB media, rather than an NTFS one; the EFI files are already in the right location).
    Thank you again good sir.
    You are welcome... and I'm happy that the change of the file system helps with windows 8 too. Thanks for confirming that.

    So as the title says, I'm trying to boot the windows 7 installer in uefi mode. It gets pretty far into the boot process, but then just falls flat on it's face. Booting the DVD in safe mode, I can see that it loads all the drivers up to disk.sys, then it seems like it's trying to display the installer GUI and fails. The top quarter or so of the screen gets blanked to black, and then everything just sorta stops. DVD stops spinning, and nothing else happens. I'm kinda restricted to uefi at the moment, as the drive i want to install on has some stuff i'd rather not lose on it, and i've just carved out some empty space for windows. 

    Hello Jerry:
    Trying to help a friend who just got a Satellite L875D that needs to downgrade from factory Win8 to a purchased disk of Win7-64 to continue using his legacy software & not have to re-train himself & buy more stuff.  Tried putting in the Win7 disk before starting the first time, but it didn't boot from that drive. Then the initial start-up factory screen didn't give an F-key to enter BIOS. Some forum notes say it might be F-2 or F-12; another post says he tried every F key.
    Do I have to do/finish the Win8 installation, and then let Win7 format the C drive? One post talks of the Win8 method to reach the UEFI, and then you say to disable secure boot. And I am not sure if the Win8 is in a "safe" partition since there are no disks included; or if I should do the Win8 install and make a backup of it, and then do the Win7 clean install.
    Thank you.

  • Switch from uefi to legacy bios

    How would you go about switching from uefi to legacy bios/boot? Would you have to reinstall windows? Can you use the hidden partitions for this? Would you need a windows install disk?

    how do I switch my partitioning scheme to MBR so I can use legacy boot/bios?
    In the System Configuration section of the UEFI, for starters, set the Boot Mode to CSM Boot. That essentially bypasses the UEFI.
    The easiest way to change the partitioning from GPT to MBR is to use old fashion tools like a Windows 7 installation DVD to delete the existing partitions and create new ones.

  • Boot Windows 8.1 in MBR mode from UEFI GRUB

    Hi,
    i installed Windows 8.1 in BIOS/MBR mode to my second hardisk /dev/sdb.
    On my first disk /dev/sda is Archlinux with GRUB 2.0 in UEFI mode.
    Is it possible to boot Windows 8.1 from the UEFI GRUB?
    The description in the wiki is only for MBR systems...
    https://wiki.archlinux.org/index.php/Gr … S-MBR_mode
    Thank you

    Actually, rEFInd can switch from EFI-mode to BIOS-mode booting; however, on PCs it's usually restricted to booting the BIOS-mode boot loader in the MBR of the first disk. Thus, you might need to physically swap your disk cables to get it to work. You'll also need to uncomment the "scanfor" line in refind.conf and add "hdbios" to its boot options list.
    Oh, you also need a version of rEFInd compiled with Tianocore, not GNU-EFI. My own main binaries are so compiled (I'm rEFInd's author), and I believe that Arch's are, too, but some others are built with GNU-EFI.

  • 660Ti UEFI/GOP & legacy bios request.

    Hi.
    Preparing myself for the Haswell upgrade.
    Can I please have the latest UEFI/GOP & legacy BIOS(es) for the following card?
    Card: MSI N660Ti PE 2GD5/OC 2GB.
    Serial#: 602-V284-050B1211045023.
    Original Vbios: 80.04.4B.00.16 (P2004-0001).
    Vbios image dump: (*https://www.dropbox.com/s/y6crdr9y1ti5t6u/MSI%20N660Ti%20PE%202GD5-OC%202GB%20GK104%20original%20bios.rar *)
    Thanks.
    PS.
    Which ver. of nvflash should I use for flashing?

    Thanks for the file.
    I upgraded just for the sake of being up-to-date,
    but I solved the problem earlier otherwise 
    So, I can't really comment if the newer/provided VBIOS solves the black screen problem or not.
    In my case the problem was from Nvidia driver 320.18.
    There is a supposedly acknowledged problem with Win 8 which silently installs  on the background
    an earlier Nvidia driver (311.06) from windows update,
    and *not* informing the user about the background install/need for reboot.
    If the user installs another/later driver without rebooting 1st it becomes a driver binary mess.
    In my case, when using 320.18 with Win 8 (even from a clean install and not messing with any previous driver),
    caused the monitor going to sleep after POST and when MB UEFI handed-off control to OS in 80% of the cases.
    A situation I could exit from only with a hard shutdown.
    So, for any other poor soul having similar problems,
    it might be a good idea to try an earlier Nvidia driver.
