How Install Windows 7 x64 in UEFI from Legacy Win10,Ubuntu.

Question: How Install Windows 7 x64 in UEFI from Legacy Win10,Ubuntu.

Hello,
I made this thread asking for your help.
Actually i have on my computer (orginally windows 10 in uefi when i bought) but now installed Kubuntu 15.4 OS and Windows 10 OS x64 in Legacy Mode,
on HDD 2TB (MBR).
I drop Grub bootmanager, writing in windows 10 recovery mode console commands
" bootrec.exe /fixmbr " and " bootrec.exe /fixboot "
so when i turn on my PC, only Windows 10 shows up.
(Its good because now i can safety delete Kubuntu without problems with booting).

Now im asking you for help, its question.
How should i install windows 7 x64 in UEFI Mode step by step?
I have right now Bootable USB with Windows 7 x64 type MBR (UEFI and Legacy bootable) FAT32.

Hello,I just purchased an E5-575-34xf which is scheduled for delivery in the upcoming days.The computer comes with no OS preinstalled. I downloaded an ISO file of Windows 10 from Microsoft and used Rufus to create a bootable USB key which I will use to install it.However, in order to do so, I need to know wether the computer uses UEFI or Legacy mode booting, since they require different settings when creating the USB drive.If anyone could answer that question, it'd be really helpful.Thanks.

I have an Inspiron 660. Last fall I upgraded Win 7 to Win 10/64.  I was looking at the System Information recently and I noticed that the BIOS mode was set to Legacy.
I see that UEFI is a step up from BIOS.
Is it safe to switch to UEFI after upgrading in Legacy BIOS mode?

Hi folks I'm new to the forum and pretty much new to forums in general so I do apologize in advance for being a noob and any potential mistakes I make.

I recently bought a used laptop (Dell 7720) I did a complete fresh install of windows 8.1, including drivers, applications etc. I cloned my HDD to a SSD and now am booting from that and using the HDD as a mass storage.

Since the install I have realized my system is set to boot in Legacy mode but I have recently read there are various benefits from booting in UEFI mode. So what I'm wondering is if the difference is worth making the change and if so what do I need to do to enable UEFI mode?

I understand how to switch from UEFI in the bios but there are other options like boot order etc.

I'm also wondering if I'd be required to re-install and start fresh or if it's as simple as switching modes. Would switching modes create some sort of driver conflict or application conflict ,etc.?

If it's really not worth the switch I'd just as soon leave it alone.

I hope that's enough info to go on and I do appreciate any help. Thanks in advance.

Answer:Switching to UEFI from Legacy post Windows 8.1 install

My own experience is that if your boot drive is MBR partitioned, and you switch your bios to UEFI mode, you will not be able to boot your OS. You will end up in the UEFI shell instead.

It is conceivable that your OS actually is on a GPT partitioned drive, and your bios is operating in legacy mode anyhow. If you check the Disk Management utility (can find by typing it in windows search bar), you should see at least 4 partitions on your boot drive if it is GPT partitioned (more if you added any yourself). In that case, you only have to switch bios mode to get all UEFI goodness.

If your drive is MBR partitioned, you will probably need to re-install. There are some utilities out there that claim to convert everything from MBR to GPT, but I do not know if they work at all, and I especially don't know if you can use one while your OS is on the drive you are trying to convert.

My system has several drives, two of which are 4TB drives. The two 4Gb drives are using GPT partition schemes. However, I'm booting off of a 240GB SSD which is using a MBR scheme.

When I installed my current motherboard, I did a fresh install of Windows 7. I didn't know much about UEFI, except that I hate it. Now I discover that there is an option to boot in legacy mode. I know in linux I can convert an existing system from UEFI to legacy mode by changing the EFI partition.

My question is, can I convert an existing Windows 7 install FROM UEFI TO legacy mode? If so, how?

Hello, currently I have the upgraded Windows 10 Pro Spanish 32-bit activated from Windows 7 Spanish OEM 32-bit on a 2011 HP ProBook 6550b LATAM which I guess has the digital entitlement since no keys were entered. I would like to clean install & format the drive using the USB Windows Pro 10 media & Brink's Windows 10 - Clean Install tutorial and have 3 questions:

Q1: checking in System Information is says the OS was installed in BIOS Legacy Mode but in the Boot menu there is an option to select UEFI instead. Which one is the best?

Q2: if clean install is done with an English US version instead of Spanish will I loose the activation?

Q3: I tried changing the display & speech language option to English in my current Spanish OS, rebooted several times and get the persistent Windows Search "these results may be incomplete" error after Indexing is completed as reported in other threads while it works fine when reverting back to Spanish display mode. Anybody knows if that bug is solved in the anniversary update?

Hi all, I've been a long-time reader of this forum, but this is my first message. I bought last year a T420 from eBay and promptly installed Ubuntu on the HDD. Last week I bought a Samsung mSATA SSD to reinstall Ubuntu on it and use the HDD as data disk. I took the opportunity to test UEFI and enabled UEFI in the BIOS. The installation was successful but when I plugged it to the dock station I lost the USB connectivity (no USB keyboard or wireless mouse), so I decided to revert UEFI to "legacy" and reinstall it. To my surprise, once I reverted to "legacy" boot I lost the ability to boot from any of the possibilities: the original HDD or even the Ubuntu DVD install media. I've played with all the BIOS options, going back to UEFI boot, and it doesn't even detect now my installation on the SSD  I went yesterday to an official Lenovo shop and they told me it was a software issue and that reverting back to BIOS should be enough, so I downloaded the "BIOS Update Bootable CD" from: http://support.lenovo.com/us/en/downloads/migr-77076 but it doesn't boot either, so I'm really stuck and any help would be greatly appreciated!  Thanks in advance.Pablo

How do you install windows?
Uefi or Legacy
I currently have installed Windows 10 Legacy
Really is better uefi
It's worth it
My bios has secure boot
And is enabled by default
If my system is mbr (not Uefi)
Should I disable secure boot?
Is it really worth installing uefi system partitions gpt?
What do you think
 

Answer:UEFI or Legacy for my Windows 10 PC?

UEFI is the replacement for the older BIOS

If you have a new PC/laptop most likely the system boots up using UEFI. Older PC/laptop comes with the legacy BIOS. However, for backward compatibility, many today's PC/laptop comes with both.

Microsoft tablets (like my MS SP3 and SP4) are exceptions for they ONLY come with UEFI.

Also, if I'm not wrong, Secure Boot is for UEFI only. You'll need to disable Secure Boot if you switch to using the BIOS. Read below

Secure Boot Overview

Having both is an advantage. One example is booting up of TAILS OS from a USB stick. TAILS OS is still using the older BIOS for this purpose and it's not supported by the UEFI for now

Hi all,

Currently having a wake on lan issue with a certain computer.

The machine is setup correctly but the windows boot information is stored in a 100mb UEFI partition, and when the computer wakes on lan, it will not boot windows, just sit at a blank screen.

When it wakes on lan it is trying to boot from the legacy device (same blank screen happens if you choose to boot from it from bios)

ive tried updating the bios but no luck, all settings seem to be as they should be.

Is there some trick to get it to load the UEFI MBR, or is there a safe way other then reformatting the machine to move the MBR over to the legacy device itself?


Thanks for any help.

Answer:Boot UEFI from wake on lan, or convert UEFI MBR to legacy.

Back up your files, unplug all other HD's and peripherals,

Boot into BIOS setup to enable Legacy BIOS. Next check BIOS Boot order for an EFI Boot Disk: remove it, set DVD drive first to boot, HD second. Then set SATA controller to AHCI. Save changes and Exit.

Then boot into installer DVD or flash stick burned or written using tool and latest ISO for your licensed here.

At first installer screen Press Shift + F10 to open a Command Box, type:

DISKPART
LIST DISK
SEL DIS 0 (after confirming Windows 7 target HD #)
CLEAN
CONVERT MBR
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

Next click Install Now to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

HI Everyone,
I need a clarification on whether or not what happened to me will be problematic in the future..
So I have a lenovo y50-70 which I upgraded to windows 10 from windows 8.1, then used a usb with windows 10 on it to do a clean install. However, when I did the install I had to change from UEFI to legacy (though looking back I realized I don't think I needed to do that and could boot from usb via pushing f12, but it's too late for that now). So I changed to legacy, changed the boot order, and was able to boot and do a clean install of windows 10....
Now I was trying to change it back to UEFI but my SSD doesn't show up at all under UEFI and only under legacy, even if I try to push f12 when it's booting up in UEFI mode there are no drives listed (just network boot options). I've gone into bios and tried changing a lot of different things to see if I could get my boot drive to pop up under UEFI but no luck. So as of right now, I can only boot in legacy mode.
NOW, I'd rather not do a complete reinstall again, so my question is if it matters that I'm booting from legacy? If it doesn't matter and won't negatively affect me later, then I'm not going to bother... But if it will cause me some headaches down the road, then I want to know if I can change it back to UEFI without doing a new clean install.
I hope my explanation makes sense... Thanks for the help.

Hi,
I recently bought a hp pavilion 15 au038ca model. It came with a lot of bloatware so I decided to clean install Windows10. I used Windows Key Finder software to find my key since it's embedded in the bios, wrote it down and went ahead to install the same version as my previous windows: Windows 10 home x64.
Before I even started with the installation, I could not see my device in the boot options( I was using a bootable usb drive). So I went to the bios and enabled legacy support and when I switched my laptop back on into boot device options, there it was: a usb drive option. So i selected it and went on ahead to do a clean install of windows. Now the problem is, whenever I load up system defaults in bios and save it, my laptop does not boot into windows. It gives me this error:

Boot device not found.

Please install an operating system on your hard disk.

Hard Disk - (3F0)

...But as soon as I enable Legacy mode, it boots up into windows. My question is, how do I install windows into uefi mode and not legacy mode? Because I read many articles saying that uefi equals faster boot times and has more advantages than the older legacy mode. And whenever i try making a bootable uefi disk, there is still no device options when only the uefi mode is on. But when the legacy mode is on, then I can see my disk under the boot device options.
Second question, how do I change my hard disk partition to gpt from mbr?
Thank you

I already did a clean install of Win10 on my Dell laptop which does seem to support UEFI mode when I went through the BIOS setup screen. My current BIOS setup is using the Legacy BIOS mode.
My question is, if I do decide to enable UEFI with Secure Boot, will I need to reinstall Win10 again?
If that's the case, then will I need to enable this UEFI before installing or after installing Win10?

I installed Win10 using the Media Creation Tool.

So does this mean that I have to start right from scratch again in order to use the UEFI with Secure Boot?
In in other words, do I need to create another Media Creation Tool for my bootable USB flash drive and reinstall Win10 all over again?

Or, can I just go into my BIOS setup and select UEFI with Secure Boot without reinstalling Windows again?

Hi,
my new laptop came with Ubuntu installed. Now I want to install Win10 from an USB Stick.
I created the USB Stick following this guide: www.tekrevue.com/.../
To boot from the USB stick, I had to disable Secure Boot and enable Legacy Boot in the BIOS.
When the Win10 installer showed me the partitions, it also said that it couldn't install Windows on that drive, because it was not a GPT partition / not GPT compatible. Only after I removed all exisitng partitions (including the DELL EPS partition - which might have been a mistake?), I could repartition the drive successfully and install Win10.
Now I wanted to switch back to UEFI Boot in the BIOS, but this doesn't work: When I switch to UEFI and click on "Add Boot Option", a message comes up saying "File System Not Found!". After that, the system doesn't reboot anymore unless I switch back to Legacy Boot.
So I am kind of stuck - what could be the problem? How could I boot in UEFI mode from the USB stick? Or is there a certain setting in the BIOS I am missing?
Thx for every hint!
Oliver

Answer:Precision 7520 - Install Win10 in UEFI mode with USB Stick

Use a better tool to create a UEFI-compatible stick.  I recommend Rufus: https://rufus.akeo.ie/.
Alternatively, if you installed Windows 10 Creators Update, there's an MBR2GPT utility you can run that will perform an in-place conversion of a Legacy BIOS setup (with an MBR drive) to a UEFI-compatible setup with a GPT drive.  You run that first, then reboot and go into your BIOS to switch it to UEFI mode, because the system won't boot AGAIN until you make that change.  You would then be able to turn Secure Boot on.

To get a storage driver, click Load driver".  DISKPART fails to list the hard drive.  Curiously, this happens when the hard drive is connected to the blue 'HDD0' port on the motherboard. It also happens on HDD1, HDD2, and HDD3. But, if I move the cable to 'SATA0', everything works just fine. 
In the recent past, my old installation of Windows 7 had been running fine on another hard drive connected to the blue HDD0 port. 
As I prepared to replace the old hard drive and install WIN10, I started poking around with UEFI, whereas as everything prior had been 'legacy'. I soon abandoned UEFI and decided to just keep it simple with legacy HDD boot settings in BIOS. This is the point at which things became weird. My guess is that either I physically damaged those HDD ports [0-3], or their is some sort of lingering UEFI configuration that is interfering.
I've loaded and applied the BIOS defaults on multiple iterations now. I've also removed the coin battery for 48 hours. I've also tried the 'hard reset' by holding in the power button for 15 seconds.  BIOS has been updated to v15 (the latest). The results are the same with 3 different hard drives.

I installed a Win 7 and Win 8 dual UEFI boot (on a GPT-formated disk of course) on HD0. Both Win7 and Win8 boot fine when the Windows Boot Manager is selected on HD0. Then I installed Win XP and Ubuntu (on an MBR-formatted disk) on HD1. Both the Win XP install and the Ubuntu install boot via legacy bios (with CSM support) when HD1 is selected in the UEFI.

This is very similar to what Theog's setup is (or at least was at some point in time; see image below).


I can boot in UEFI mode on Disk 0 and boot either Win 8 or Win 7, or I can boot in BIOS/MBR mode on Disk 1 and boot either Win XP or Ubuntu. The problem is that I can not seem to get all four options to work from one boot screen.

The closest that I have gotten is to load a Windows 7 boot manager (bootmgr) and a BCD store on the Win XP partition and use EasyBCD and BCDedit to create boot options for all four operating systems. WinXP, Ubuntu, and Win7 all boot up fine this way, but Win8 gives me a boot error saying something like "invalid signature for winload.exe".

Is there a way to get this to work?

I am not sure if this subforum is the right place, if not, pleases help me transfer to the right forum...

I recently just build a new setup with Asus P8Z77-V LK, this motherboard comes with UEFI boot and legacy BIOS boot support.

So I tested install windows 7 in both mode, and I didn't find any advantage of UEFI consider it is a new technology been promoted quite a lot for recent years.

The benefit I found is: a graphic BIOS setup, which is useless to most users if you don't OC. Even you did, I still find using keyboard to navigate through the menu is much easier than mouse.

Faster boot time? very negligible, could be 31 seconds compare to 28 seconds. As I timed use my stopwatch, the value could include a few seconds human error as well.

Support boot from > 2.2TB HDD? nowadays most user use SSD as boot drive so this really doesn't matter.

GPT disk partition? don't see any benefit here compare to legacy MBR...

Anyone can enlighten me what is the advantage of UEFI here?

Thanks a lot!

Answer:What's the benefit of UEFI and install Windows in UEFI mode?

Thanks for adding information about EFI BIOS which present a problem for many during installation and repairs.

For this reason alone, I would advise disabling EFI BIOS in BIOS boot order or choosing Legacy BIOS in BIOS setup, installing normally to an MBR disk.

Wiping a HD already formatted as GPT disk with Diskpart Clean Command can clear the way for it to install as MBR. Sometimes it also takes runnning the command "Convert MBR" to change disk from GPT.

Question: legacy vs uefi

 Hi all, First of all I'm a new Lenovo user and realy love the hardware! I have however a strange behaviour with UEFI on my new T540p. At least I think this is strange behavour for UEFI. When I set the boot mode to UEFI it takes 8-10sec longer to boot than when I set it to legacy mode.The difference in time is located between pushing the power button and the actual starting of windows. Loading windows itself takes equal time in both modes.   Latest Bios version is installed and all other bios settings are the sameBy my knowledge UEFI should be faster to boot... Any one else noticed this behaviour and or has a solution for it? Many thanks

However. After the installation was finished my touchpad was not even recognized, i mean, i was not even listed in the device manager, so i read somewhere on the Acer forum that switching back to UEFI would solve this problem.
Well, i switched back to UEFI and now when the laptop start i recieve a message that says -No bootable device found!

Even if i try to use my bootable USB drive, the list is empty.
So i switched back to Legace again and guess what. Windows 10 starts like there was no problem.

Hello,

I have just finished making myself a decent gaming rig and im on the last step at the moment; which is installing Windows 7. I have noticed that when trying to install Windows on my pc there's two option: one is Legacy and the other is UEFI, and since I'm not really and expert when it comes to such things, I decided to postpone the installation process until I figure this out. So, which of these should I choose as an installation method? I'd really appreciate it if someone could help me with that. Thank you!

Answer:UEFI or Legacy?

UEFI has some advantages over BIOS,such as:

Faster booting
Support of 128 logical partitions
Support for disks which have a size of over 2.2 TB
Support for Legacy BIOS

But look here:QuoteThe problem is that the PCI-E slot on the 360 Motherboard is very close to the CPU fan enclosure whereas most of the graphics cards I've looked at are double width and as such, are too wide to fit.That was found on another forum.

Question: UEFI/Legacy

I am not a happy camper with Windows 8.
I am confused with the Legacy and the UEFI boot methods. The reason I am confused I think, is because I read to darn much on the Internet. One bit of confusion is with respect to changing from UEFI to Legacy. It would appear from some comments that if I do that, Windows 8 won't boot anymore. I would have to change back to UEFI for indows 8 to boot. I also read that changing back to UEFI could be a major problem when trying to access the BIOS. No, I am confused. My ultimate goal is to set my laptop up to dual boot Windows 8 and Ubuntu. Like I have been doing for the last multiple years with XP and Windows 7.
Helpful comments would certainly be appreciated.

Answer:UEFI/Legacy

I don't quite understand what UEFI is, it is firmware, or is it Microsoft's new Boot GUI? I've set my systems to boot Legacy mode, and since I did that, I have no trouble getting into Safe Mode.

Does UEFI access your BIOS as well? That's what I'm worried about. The idea of not being able to access the BIOS from outside Windows 8 makes me itch. I think the Legacy Menu may allow that though - You can set it to Legacy, and if you can't access the Bios, then you can switch it back. I forget the command lines to set it, but they are in a tutorial here. It's BCDedit.

Answer:EFI, UEFI, Legacy BIOS.......

Your OS seems to be currently installed in Legacy Mode, that means your drive is probably formatted using a scheme called MBR. For Windows to boot in UEFI mode, it required the drive to be formatted using a different scheme called GPT.
If you can, backup the drive and reformat it to GPT if you want UEFI.

As far as the benefits go, Legacy is old, UEFI is new. It's faster, looks prettier while booting :P. Thats pretty much it for the average consumer.

Hi, I just purchased the HP x360 Spectre, which came with Win 10 Home and UEFI/SecureBoot turned on. The boot disk is GPT. Also, there are 4 partitions on the drive out of the box, as listed in the : EFI SystemRecovery PartitionRecovery ( D: )Windows ( C: ) This is my first Windows above 7, and the first that is not Legacy BIOS and MBR boot disk, so I'm a little lost with all this. I need to backup the drive before making changes to the new laptop using my Macrium Reflect Win7-based PE USB pen drive, but when I disable SecureBoot and enable Legacy Boot and move USB key to the top of the boot list, it boots Reflect under PE OK, but no drives are shown in Reflect to back up. I'm not sure at this point if this is because Version 5 of Reflect doesn't support UEFI (although I'm not sure that's a factor as I've booted), or some other factor resulting from UEFI and GPT. I know Reflect V5 can backup GPT drives, as I do it now, but have only imaged MBR drives. There are newer version of Win PE; Ver 4 based upon Win 8, and Ver 5 based upon Win 8.1, which might solve my problems. I'm trying that next. If anyone has any insight, it would be much appreciated. Also, are UEFI and BIOS connected in some way to MBR and GPT, so that one requires the other, or can you mix and match.

You can change the boot logo in UEFI mode by modifying the relevant ACPI table (BGRT) with an EFI application before booting. AFAIK, the only application for this is currently my own, HackBGRT.

Hello,

Right before I performed a clean install of Windows 8.1 x64 on my Inspiron 3520, I switched to the Legacy BIOS *facepalm*.

When I enter the legacy BIOS and enabled "secure boot", I performed a restart that gave the following message "internal hard disk drive not found, to resolve this issue, try to reseat the drive. No bootable devices--strike F1 to retry boot, F2 enter setup menu, F5 enter PSA". Of course, when I go back into the BIOS and disable secure boot, it reverts back to legacy and boots up Windows 8 just fine. What I'd like to know is, how can I revert back to UEFI so I can change the boot-up option and perform a clean install under UEFI.

Any help would be greatly appreciated! I've found a couple articles but I just want to make sure I'm headed in the right direction and if maybe there is a safer and easier way to get this done...

Answer:Installing some OS's in UEFI and some using Legacy BIOS

I am never a fan of using dual boot. I have Windows 10 installed on a separate GPT SSD and Linux installed in MBR SSD and run them separately using Boot Menu so they are completely independent from each other.

I did mention in your other thread that dual booting using MBR is preferable which you can set the Windows boot manager and GRUB boot loader separately. The traditional way is Linux override the MBR and took over the booting process for both Windows & Linux. The non traditional way is to put the GRUB Boot loader in its own partition then use Easy BCD to set up the dual boot, this way they are independent so if there's an update/upgrade from either one, you won't break anything. In addition, you'll get a nice GUI dual boot Menu from Windows, not the ugly GRUB.

Here's an example:

GRUB controls the booting process for both Windows and LinuxPut GRUB in its own partition and use Easy BCD to set up dual boot.
NOTE: During Linux installation, you have to tell Linux not to use sda (MBR in Windows) but its own partition.

Answer:Whats the Different with Legacy Bios / UEFI ?

As for the questions about UEFI in general - basically, UEFI is a replacement for BIOS. Without going into technical details, the most important difference is that UEFI is 64-bit, while BIOS works in 16-bit real mode. This adds certain amount of latency in the boot process (and resume from sleep) because your 64-bit processor will simulate 286 CPU from the power on all the way until your OS starts booting, only then your OS will switch it in 64-bit mode. New Windows 8 PCs don?t include the traditional BIOS. They use UEFI firmware instead, just as Macs have for years. Rather than have modern PCs wait several seconds for a key press and delay their speedy boot process, you?ll have to access a boot option menu after booting into Windows.

Hi everyone, I'm trying to set up a dual boot on my X220, but can't seem to get it working.I tried to follow the tutorials available on ThinkWiki about SSD partitions and optimization, but it didn't work.Also, I'm a bit confused between MBR and GPT, and UEFI and LEGACY, and Syslinux and Grub.From what I read, it seems we're supposed to use GPT partitions with UEFI boot, which is what I'm trying to set up. Have any of you successfully set up a dual boot Linux (Arch) + Windows (7 home) on SSD and HDD?If so, could you give me the options you chose for partitioning and boot? I'm thinking about a UEFI boot with GPT partitions.For Linux, / (root) and /home on the SSD, and var on the HDD.For Windows, I don't know. Should I install the whole OS on the SSD, and give it access to a DATA partition on the HDD? I'm aware my post doesn't provide much information about my issues, but what I'm looking right now is a configuration that is known to be working on the X220, and on which I can focus my work. Also, the configuration should minimize the number of read and write on the SSD. Thank you

Say I install Windows as Legacy, can I later change it to UEFI? Or doing so will require another clean install? Thanks.

Answer:Changing a Legacy system to UEFI

For UEFI disable Legacy in BIOS, boot the Win7 DVD as a UEFI device. This change means the old install won't boot and needs to be deleted along with all other partitions to force the installer to change the HD format to GPT format - be sure to unplug all other HD's first.

So for UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums. For install via flash stick special steps must be done from UEFI Bootable USB Flash Drive - Create in Windows

Or to Bypass UEFI to Install WIn7 for a normal MBR install.

If your PC or laptop supports UEFI and legacy mode then the following tips may help you. Legacy enabled:If the bios setting is legacy enabled then hard drives and USB devices will normally boot.  If you are using two independent hard drives that are not connected by boot manager then the UEFI boot hard drive will always boot first before the legacy hard drive unless the bios allows you to change the boot priority. Legacy disabled (UEFI mode):If the bios setting is legacy disabled then only UEFI devices will boot.  You may run into no hard drive selection menu, no boot option menu or Boot Device not Found followed by a message Hard Disk (3f0). USB flash drives boot considerations:If you wish to boot up a USB flash device using Windows 7 repair, Windows 8 repair, Windows 7 or Windows 8 installation media then be sure to create the flash drive formatted as FAT32.  You may notice a bootable flash drive showing twice in the boot menu, one marked UEFI and one not marked UEFI.  Both will boot up. The popular MS Windows 7 USB WIndows installation media creation tool will create a NTFS flash drive using a Windows 7/8 iso file in NTFS format which is not bootable in UEFI mode. It works fine in legacy mode.  To get around the NTFS issue, create the flash drive in NTFS then copy the contents to your hard drive, quick format the flash drive to FAT32 and then copy back the contents back to the hard dr...

I bought a brand new Sony S series and it was shipped with windows 7 and boots in UEFI mode. I have encryption software I need to install, and it's not compatible with UEFI mode. In my bios I see the option to change the boot mode to legacy, but when I do that and restart the computer I get this message 'operating system not found'. How can I run my computer in legacy mode? Do I have to set the bios to legacy and re-install windows?

Answer:UEFI/Legacy bios issue

1) Install encryption software that supports UEFI.

2) Reinstall in legacy mode.

Hello,

I've installed Windows 10 and Ubuntu using UEFI.
But, now I created a bootable USB for a Linux that does not support UEFI, but only Legacy.
I mean, when I plug the USB to my laptop, the UEFI does not recognize it, only the Legacy BIOS does.
Is it possible to simply proceed to install the other Linux using Legacy mode? Or it will cause problems?

Thanks

Answer:Installing some OS's in UEFI and some using Legacy BIOS

I am never a fan of using dual boot. I have Windows 10 installed on a separate GPT SSD and Linux installed in MBR SSD and run them separately using Boot Menu so they are completely independent from each other.

I did mention in your other thread that dual booting using MBR is preferable which you can set the Windows boot manager and GRUB boot loader separately. The traditional way is Linux override the MBR and took over the booting process for both Windows & Linux. The non traditional way is to put the GRUB Boot loader in its own partition then use Easy BCD to set up the dual boot, this way they are independent so if there's an update/upgrade from either one, you won't break anything. In addition, you'll get a nice GUI dual boot Menu from Windows, not the ugly GRUB.

Here's an example:

GRUB controls the booting process for both Windows and LinuxPut GRUB in its own partition and use Easy BCD to set up dual boot.
NOTE: During Linux installation, you have to tell Linux not to use sda (MBR in Windows) but its own partition.

We need to use Legacy boot for a PXE imaging system.  This Elitedesk 800 G2 will not keep the Legacy Support Enable and Secure Boot Disable setting through a restart.  We have searched and tried many options found on this forum and elsewhere (several days worth of time) to no avail.  We have gone from BIOS 2.05 to 2.12 to 2.13 with no change in symptoms.  We have even taken out the SSD and put in an imaged HDD and not been able to keep the setting.  In all of this, under the Boot Options, both UEFI and Legacy are checked, but grayed out so neither can be unchecked (options under UEFI can be changed and saved).We have reset to factory defaults many time, Cleared the Keys, turned off and on many other options, created the admin password, and many other things found on this forum and elsewhere, including of all things, the HP manual.  Somehwere, they have to have a way around this.  What good is a device that is so secure, that the IT department can't even manage it?

Hi: I have the older 8200 Elite CMT, and in the BIOS's boot order menu you can use the F5 key to turn UEFI boot order completely off, and then just legacy mode exists for booting. Maybe you can do the same thing with yours... The setup guide for your model is vague.  It just states:  UEFI Boot Order...default is enabled.  If that is the case then there must be a setting to disable it.

I have disabled the secure boot option and enabled the Legacy boot option which allows me to boot from USB stick. However, UEFI takes precendence over Legacy boot and I don't want that. For a little school project that we are running we want to run the educational OS Sugar on Stick(on a USB stick) to run straight from the stick instead of kids pressing 3-4 different buttons to get to that.  In short, I want to change boot priority from UEFI first to Legacy. Let me know how to do it? Whether its possible or not? If not, then I don't need these 4 laptops that I ordered and I will return the laptops. Thanks a lot in advance. -Ritesh

I have read the tutorials and the many posts on this topic so apologise for creating another post on an old topic. I am hoping I am being an idiot and have just missed something really simple.

Scenario 1: Created UEFI bootable USB, using Rufus, configured BIOS with CMS disabled and Secure Boot enabled. USB drive is recognised in BIOS as UEFI and selectable as a boot option. Windows files show as loading and then it sits with the Windows logo doing nothing.

Scenario 2: Created 'normal' bootable USB, using the Windows Download Tool, configured BIOS with CMS enabled and Secure Boot disabled. USB drive is recognised in BIOS but not as a boot option. Get a message prompting to insert boot media.

I don't have a DVD drive so USB is my only boot option. The system is a 3XS Scan custom build but the OS stopped recognising mouse and keyboard even in safe mode so I opted to wipe the hard drive and start with a fresh build. The OS was being unstable anyway and it was time for a clean install.

This is the first time I've tried a build since UEFI has started rolling out and it's nowhere near as straight forward as it used to be... Just used to pop a USB or (remember these...) a floppy to a basic command line to set up the partitions and load up the OS. So, what I am really saying is that I am utterly clueless in this new world order and will need handholding...

Thank you for any help and suggestions.

After about 6 hours of trying to setup an Ubuntu dual boot on my Vaio svE14A15FG all i succeeded in was eventually deleting the partition table. (I was told to run gdisk so the Live CD would see my windows install and automatically install along side as all manual efforts weren't working.) I'm running TestDisk at the moment to see about getting it all restored as I've moved around a bit in the last year and am not 100% sure of where my system restore disk has ended up. However I do also have a physical install disk and unused product key from family pack. That disk will only boot in legacy mode though. If I'm not too worried about losing files(everything important is also on my desktop) and having a clean install would I be missing out on anything important by using the legacy mode instead(which would also make installing Ubuntu alongside easier)?

Then in the UEFI Bios Disabling the Secure Boot Control in the Security tab. Ive doe this but it also says in the Launch CSM option to change to enable. Problem is this option is not showing. So how to I change to Legacy mode so that I can change the Boot device order and boot from the CD?

While trying to fix a boot error (0xc0000034) on my laptop I accidentally changed my computer's BIOS from UEFI to Legacy, is there a way to change it back?
The computer is clean so it doesn't matter if it's a method that causes loss of data. I have a bootable USB with windows 10 (maybe 8) on it. At some point I got into the menu for this, but must of the times I just get straight to the BIOS.

The selected disk is of the GPT partition style." so I couldn't get past from there anyway

Did some research and it appears after you disable UEFI, in order to install the card, you can then reboot and enable UEFI and it will reconfigure the UEFI with the new card.
