Satellite L850 & Win 8 UEFi: How dual boot UEFI win 7 ?

Q: Satellite L850 & Win 8 UEFi: How dual boot UEFI win 7 ?

Hello to the forum. Thanks for the welcome. And thanks for pointing me in this subforum.

I have a notebook toshiba satellite L850-1HU with UEFI

Default is win 8 os, recently upgraded to 8.1.

Now I need to win 7.

I have a professional license N sp1 x64 and then supports UEFI

Is possible to combine the systems in dual boot and both in UEFI mode?

I see from your guides that for installation the UEFI is necessary partition in a certain way.
What should I do if I want to leave intact the UEFI partition of win 8 (5 partition)? I just make only space for win7(1 partition) that will use the same 4 partition UEFI of win 8 or i make other 5 partition???
And which of the two systems will handle the boot? I can decide I?

and the warranty? restores factory work?

If I change hdd, and install win 7, when I put the old hdd, it works as before removing it?

Sorry for the confusion! I hope you manage to understand me and help!

Ciao forum! E grazie! Saluti dall'Italia!

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Yes. This is how I do any OS tests\'dual boot'\experiments etc with zero chance of damage to the original boot OS\hd. Am keeping a bunch of old HD's for the purpose. The downside is the slight risk for some mechanic\connection problems, just be careful, remember to power down! So if you don't find it troublesome to switch HD's, IMO go ahead and try that route.

Hello, I have a Y720 tha comes with a 1x 129 GB M2 SSD and x1 HDD, in UEFI mode. I'm currently trying to replace the M2 SSD with a newly bougth Samsung 960 EVO M2 where I would like to install Windows 10 also in UEFI mode, as it has better power management than Legacy. But I have tried booting the Windows 10 installer USB stick and the laptop does not recognize in bios. I have created the usb stick with RUFUS 2.18 (latest), choosing UEFI + GPT and Fat32 file format. Before that I also tried restoring a system backup image I created from the former M2 using AOMEI Backupper but I couldn't boot the USB utility to do so either (the same happened: Bios does not recognise it, despite creating it choosing UEFI mode) Things I have tried: 1. Disabling secure boot (although the Secure Boot Status staed "Enabled", so I used the "REset Secure Boot mode" option too...)2. Chaging Optimal OS Setting to disabled in seetings, but still no use3. Using the Novo Button on the right part of the laptop. Of course, changing boot mode to Legacy would allow me to install Windows from USB ....but in Legacy mode, which I'm trying to avo So ...is there a way to boot a UEFI usb stick to install Windows in UEFI mode from it?  thanks!

Trying to understand handshaking between UEFI & Win 7. Have Win7 Pro sp1 64 installed on SSD, mb=Asus F2A85-V Pro. Example: boot to flashdrive to do Acronis backup of SSD; remove SDD, insert spinner; boot again to flashdrive to do Acronis restore to spinner (to test backup); remove flashdrive, boot to UEFI, set UEFI spinner as default, save & reset; spinner starts boot (#1), Win logo shows briefly, reboots (#2) and shows Win repair/normal screen; choose normal; Windows desktop shows; new driver is loaded for spinner and asks for reboot (that part I understand); reboot (#3) starts and again briefly shows Win logo before yet again rebooting (#4) to the Win repair/normal screen; again choose normal & all is happy. But then I remove the spinner, insert the SSD, and have to go through the whole deal again. Why so many reboots?

Similarly, if I change any hd/flashdrive configuration, my UEFI boot selection is lost & I have to reset it again - sometimes with the multiple reboot scenerio, sometimes not. Sure wish I could force that the UEFI selection stay there as long as the selected drive is installed.

A:UEFI boot keeps changing; UEFI/Win7 handshaking confusion

Hello and welcome diana look I am having a little difficulty in following the train of the thread.

Now do you mean you just backed up the SSD to a USB stick ? then tried to transfer that USB stick back up to the spinner? If it was just a back up then I don't think it is going to work because it is only a backup.

To make the spinner the boot device I would be cloning the SSD to the spinner. I wouldn't mucking around with sticks as I cannot see why that is necessary.

**** You need to enable Legacy MBR by Enabling Launch CSM in the EFI Setup ****

Hello all,

This is my first post. I am a Windows 7 user and now (against my will) Windows 8.

I bought an ASUS N76 laptop pre-loaded with Windows 8 so these are the new generation n76 series. The old ones come with Windows 7. Anyway...

I attempted to boot a Windows 7 ULT 64 install DVD but the install hangs on the Windows logo/flag. So...

- Windows is loading files is shown and hidden
- The animated Windows logo appears and then it just hangs....go figure

I have no idea what is going wrong. I went into the UEFI setup and the only option for my BR is EUFI boot.

I also added a "boot option" asking the EFI to boot "efi\microsoft\boot\boot.efi" or "\efi\microsoft\boot\boot.efi" but when selected (from Boot Override), the screen goes blank for a few seconds, the BR starts spinning and I am thrown back at the EFI so it looks like it cannot find the file. For path, I selected the BR device and at the end has a "\".

I have secure boot disabled. (yep, I have an option for that). So now I am left empty handed and I am stuck with Windows 8. I even put in a brand new SSD hoping I would install W7 on it but I can't even start the setup!! Argh....

I am very experienced with MBR and BIOS but I am a complete newbie to UEFI. I don't know what is going wrong and why the setup hangs....Ther... Read more

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.

A: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"

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.

I am in the process of doing a number of clean installs. I am trying to make a decision as to whether or not to utilize the UEFI and Secure Boot modes which are available on the MBs.

It seems from an initial attempt, that I cannot simply use UEFI/GPT without turning on Secure Boot...that is one must NOT use CSM (turn it off) and USE Secure Boot. You cannot use UEFI without Secure Boot.

Is this correct? I am considering us9ng UEFI without Secure Boot because I hear it is faster.

However, I am concerned that I will run into all sorts of trouble turning Secure Boot on with respect to double booting Win 10...and additionally with creating images with Acronis.

I have been in the habit of creating a new PC with an extra drive with a cloned OS...then disconnecting the drive so that if the first OS drive fails, the person can boot up quickly with the other drive. I am concerned that there will be a problem with Secure Boot.

I mean, how many times have I been infected with a root kit.....some virus that take over at boot time...Answer...never since I started with PCs in 1991!

So, anyone really think Secure Boot is worth it?

A:UEFI/Secure Boot or not to UEFI/SB, that is the question..

Secure Boot does not affect the speed of your computer.

Windows 8/8.1/10 are compatible with the Secure Boot.

I don't know about Acronis True Image but Macrium Reflect is compatible with the Secure Boot.

It is a very important security feature.






Microsoft designed Secure Boot to protect the computer from low-level exploits and rootkits and bootloaders. A security process shared between the operating system and Unified Extensible Firmware Interface (UEFI, replacing the BIOS), Secure Boot requires all the applications that are running during the booting process to be pre-signed with valid digital certificates. This way, the system knows all the files being loaded before Windows 8 loads and gets to the login screen have not been tampered with.

If a bootloader has infected your computer and it tries to load during the boot-up sequence, Secure Boot will be able to undo all the changes and thwart the ... Read more

Dear Friends,

Long time reader of this forum but a first time poster, so please forgive me if this question has already been asked and answered.

Laptop: ASUS UX31A-DB71, latest BIOS: 218

Originally my laptop came with Windows 7 and when i looked at disk management my disks were formatted with UEFI schema. One of my friend gave me a UEFI bootable USB drive loaded with Windows 8. So, i thought why not give it a try. So, I created a backup of my OEM Windows 7 and saved the iso files in a seperate external HD (created twice just to be sure . Now, i decided to load the Windows 8. Booted into the BIOS and there is an option to select the USB drive along with the UEFI option for that USB drive. I selected the UEFI option but some reason it does not boot into UEFI. So i decided to select the standard USB install and this option let me install windows 8. In the process of installing i formatted the partitions and made a single partition and installed Windows 8 on it. I am guessing now the drive is not GPT but MBR. I also noticed that his installation USB disk had an option to select either 32bit or 64bit of Windows 8...I find this kind of odd. Would Microsoft create a same iso file with both versions? I am guessing he created the USB from a illegitimate source.
I am planning on purchasing Windows 8 Pro version as an iso but wanted to be confident that it would work with UEFI architecture.

Questions:
1. Why would the system NOT boot from UEFI?

Every things works with normal Legacy mode in our environment and k2000.
I have made WINPE 10 boot file as a normal procedure with k2000 Media Manager (like in legacy mode). And uploaded it to k2000. Of cause I have re-cached my drivers when making new a boot source. 
I have setup our new DHCP so it can boot with UEFI and it works!, and I can see my boot sources when boot up the client in UEFI mode.

I am stuck what could be wrong or what have I missed ? Please help

rdubayah,
If your computer was running WIndows 10 without any issues prior to downloading the Anniversary update, then you would not have had to change any settings in the bios to install the update.The UEFI and Secure Boot settings are to enable booting with a USB or DVD to install Windows.
Disable Legacy Boot Mode and Enable UEFI
Start the computer and TAP the F2 key to enter the bios. Once in the bios Press F9 to Restore the bios to the Default Settings. F10 to save changes and exit. You could have a hardware problem. To run a hardare diagnostics on the computer you would start the computer and TAP the F5 key. Insert a cd/dvd in the optical drive for running the diags.

I have a new laptop, a toshiba p870, that came with windows 8 preloaded. I needed windows 7 for compatibility reasons with a few programs and after a bit of research and struggle I eventually got it installed on a second hard drive in the computer but in the process I had to change the bios settings to disable secure boot and enable CSM. After that Windows 8 will no longer boot even if the second hard drive with windows 7 is removed. I have no way to access the bios in order to change this setting back, the only way to access it was by going through the windows 8 recovery and troubleshooting settings, inserting a windows 8 disc (from a previous installation on a different computer, non-uefi) didn't offer the uefi firmware options in recovery mode. What can I do to restore access to windows 8 on this system?

EDIT: I finally figured it out. You must hold shift as the computer shuts down in order to get the toshiba logo and the option to enter the bios with F2 to show up at startup. This isn't a very convenient setup for dual boot, having to change between CSM and UEFI to choose operating systems but it works.

Ok, this has been dealt with in various places but not to my total satisfaction. So bear with me if the answer is hidden somewhere in the forum.

I've got an oem asus with 2 hdds the first of which has Win 7 64 home pre-installed via uefi boot manager. It is a gpt formatted disk. The second disk is empty and is set up with mbr. I wish to dual boot onto the second disk with Win 7 32 Pro but fear a rejection due to the fact appparenly Uefi will not manage 32 bit installs/boots. More to the point , will the mbr variance on the 2nd disk somehow make for an exception to this 32bit 'prejudice' on the part of uefi or simply make matters worse? My bios has a single option regarding a legacy setting connected with uefi which is disabled. PxO... or rather. Gregrocker seems to think obviating the problem with 2 physically separate installs (i.e. Hdd disconnect) will allow a Bios based boot as opposed to a Uefi/Windows managed one. Is this workaround a sure thing and my only option or is there a practical way to go the classic route with the auto boot loader screen on start up? Perhaps a better way to put it is..on dual boot systems is it true that you can't have BOTH uefi and the bios directing the show. You gotta choose one or the other. Frankly, to my novice mind this whole problem seems to be a regression from the XP days. Anyway, a definitive answer from you all would be more than welcome. Thanks loads.

I have been attempting to install Windows Server 2012R2 on the second, M.2 SSD (Disk1) into a GPT, NTFS partition.
Since this system has no DVD, I made a bootable UEFI thumb drive with the contents of the .iso installation for Server 2012R2.
The thumb drive boots OK and I can begin installation, but when it comes to choosing the target for installation, the M.2 SSD is not visible in setup.
The M.2 drive is clearly visible inside Windows 10 Pro as the D: drive.
So...I mounted the .iso setup file in Windows 10 and ran setup.exe. The install began and could see the target M.2 drive, and began loading files on the second SSD. It then attempted the first of several restarts that come with this process with the new Server 2012 R2 environment.
It sucessfully modified the Windows Boot Manager before the restart, then restarted, and the setup program gave an error because it could not find the target partition on the second SSD.
The setup environment then modified the Boot Manager to "Windows Setup Rollback" and proceeded to enter an infinite loop, attempting to delete files from the unreachable M.2 drive. I manually choose Windows 10 on the boot menu, and once booted changed Windows 10 back to the default OS.

I install Win7 and press Ctrl-Shift-F3 to form SysPrep, same as Win8.1 in 2nd partition.
I made this becuase I've 25 Dell new Win8.1 Computer which are UEFI. So I want to make a master computer which has both Win7 and Win8.1 with SysPrep in it. Then I want to clone it to the other 24 Dell computers.
CASE 1 : 2 different partitions with 2 different Windows :
---------------------------------------------------------------
If I install both Windows like above, when Sysprep Generalize Win7, it works fine. But if I SysPrep Generalize Win8.1, it's fine also, but never can boot again back to Win7. The start boot option is like this :
Windows 7
Windows 8.1
If I choose to boot Windows 8.1, it's fine. If I choose to boot Windows 7, it ever boot to Windows 8.1. It means nomatter I choose to boot which Windows, it all goes to Windows 8.1 ?????
CASE 2 : 1 partition for Win7 + Win81.VHD :
---------------------------------------------------------------
I install Win7 (C and press Ctrl-Shift-F3 to form SysPrep.
I create a Win81.VHD in Drive D: , imagex Win8.1 install.wim in it. Also press Ctrl-Shift-F3 to form SysPrep.
Sysprep Generalize Win7 is OK , SysPrep Generalize Win8.1 is also OK. But after that I can only boot to Windows 7 fine, when choose to boot Win8.1 , it always restart and back to the boot menu ?????
Can anyone help ? Thanks a lot.

Hi there bleeps :D
I got a sony vaio laptop, and it has windows 7 OEM on it. Tried to install Linux on it on another partition, and the installation was fine and finished. Then I got into the windows and used BCDedit to add a new value for the linux distro I installed. Now, when I boot the laptop, it gives me 2 options, win and linux... but if I run linux, it gives me an error and doesnt find the bootloader.
If someone can guide me through the process I'm ready to erase all my data from the HDD and repartition everything. My only aim is to be able to dual boot Windows 7 with Kali Linux.
 
 
Current partitions:
1- SONY partiton (dont know what the hell that is) ~260MB
2- Recovery parition ~20GB
3- EFI boot partition ~260MB
4- XXXXXXX partition ~300MB (has no name and i don't know what it is for)
5- Windows 7 installation ~70GB (C:/ drive)
6- Linux boot partition ~300MB (/boot)
7- Linux root ~12GB (/ )
8- Linux home ~40GB (/home)
9- Unallocated space ~450GB

A:Want to dual boot Win7 with Linux on a UEFI-based laptop.

I don't know Kali Linux at all, but I have installed Linux Mint 16 on a UEFI Windows 7 system.  Current versions of Linux Mint, Ubuntu, Fedora and OpenSuse at least have support for UEFI.  For Kali Linux, it appears you will have to make a custom ISO with UEFI support - https://forums.kali.org/showthread.php?271-How-to-EFI-install-Kali-Linux
 
To install Linux Mint, dual booting with Windows 7 in UEFI mode here is what I did...
 
- Starting point was Win 7 x64 installed in UEFI mode, GPT partitioning scheme on all attached disks, and 100Gb unpartitioned space on one of the disks.  If you need to re-size existing partitions to create space use Gparted.
 
- Boot Linux Mint DVD in UEFI mode (this involves going into the BIOS, and in the Boot Override menu choosing the name of the DVD drive with UEFI in the name, as per below).  NB This is important - if the installer is not booted in UEFI mode, it will install in Legacy mode and this will not work if the existing OS is installed in UEFI mode.
 

 
- Choose "I want to do something else" aka custom installation in the installer
 
- Created separate root, home and swap partitions (swap, if using, should be equal to ram).  The root and home partitions were formatted to Ext4 FS.  I allocated 20Gb to the root partition and the leftover free space to the home partition.  Mount point for root is /, and for home is /home.

Dual Boot W10 + W8.1 installs using 2 SSDs. Any thoughts on why there are less partitions on SSD install #2?

SSD 1 W10 (installed first) C Drive:

- Recovery
- System
- Reserved
- Primary

SSD 2 W8.1 (installed last)

- Reserved
- Primary

Am I right in saying that install/SSD 2 shared the (Recovery, System) UEFI boot partition and that this is not good if I remove SSD1?

How do you prevent this on SSD #2, by physically removing SSD #1 when installing OS #2?

Appreciate any help.

A:Windows 10 Dual Boot UEFI Missing or Shared Partitions on SSD2?

Yes, the only way to ensure that a clean install of Windows will not affect any other hard drives/SSDs with system partitions on them is to disconnect them when installing Windows to the drive you want it exclusively on. Unplugging either the data cable or the power cable is good enough.

Hi

Satellite C850-F0055 laptop

I am trying to figure out how to access the boot menu at power on.
I have tried f2 & f12, f2+fn & f12+fn, tried holding the keys, tapping the keys
holding for 1 second etc, I have tried all the f keys as well, tried esc, backspace
ctr+ del nothing works.
what happens when I boot up, within 1 second 'Toshiba Innovation' screen appears
and then proceeds to load Windows 8.1.
I can access BIOS/UEFI via charms-pc settings and navigate to UEFI and get in that
way but that won't help if I need safe mode.
My settings are:- ODD/USB/HDD, boot speed set to 'normal', Secure boot disabled
I have a dual boot system with Windows/Linux.
If I put a boot disk in and power up, the boot option is totally ignored but with the disk still in
and Windows loaded and I access UEFI via the above route, enter UEFI and exit again
immediately the disk bursts into life and loads the disk as is supposed to happen at start.

I have not sure where to go now so any help will be appreciated

Hi all,

So I got a new laptop its a Lenovo Y700-15ISK, UEFI Bios. I am trying to get the machine to dual boot Windows 7 and Windows 10. I installed Windows 10 first, no problem. Windows 7x64 is just not working.

My windows 10 was a fresh install, slipstreamed updates and drivers from Lenovo using NTLite.

Windows 7, slipstreamed all Lenovo Windows 7x64 drivers, also windows updates (sp2). Windows seems to install fine but when it reboots after the install and boot picks Windows 7 from the Windows Boot Manager, I get a blue screen! 0x0000007e. I installed the USB 3 drivers via NTLite in booth the install.wim and boot.wim. I don't have an issue with is asking for drivers at the Windows 7 install.

After installing Windows 10, I made these changes to the bios.

Boot mode: Legacy Support
Boot Priority: Legacy First
Turned off OS Optimized defaults

Installed Windows 7x64 from usb stick, install seems to work but when it reboots,
BSOD BLUE SCREEN! Same error 0x0000007e
Also unable to boot into windows 7 using safe mode. I get as far as:
C:/Windows/System32/drivers/disk.sys
then it BSOD's
Totally totally at a loss right now!

Scenario:
Upgraded Video Card from GTX 560 Ti to GTX 1060 Strix, machine boots but no video output or just black/blank screen.

Did a bit of online research and realize that two ways of fixing this
1. Change PCI setting to Legacy in BIOS/UEFI
2. Update to latest BIOS.

I decided to try and update BIOS to latest BETA (13w) using @bios from Windows. Everything went ok, reboots fine and still does now with Windows loading no problem, BUT i can't get to BIOS/UEFI???

All i get is the UEFI empty blue screen, no menus/options, just blank screen...

So i thought maybe i can reverse back to previous BIOS from windows but program wouldn't allow this. I tried sticking BIOS file in USB but the problem is i can't get to BIOS.

I Have tried running backup BIOS as board has two, but still same problem.

The short answer to the headline?s question is that a UEFI scanner is all about helping you protect your computer against people who seek to take it over by abusing its Unified Extensible Firmware Interface (UEFI). A successful attack on a system?s UEFI can give the attacker complete control of that system, including persistence: the ability to secretly maintain unauthorized access to the machine despite rebooting and/or reformatting of the hard drive.

As you can imagine, this form of persistence is not a virtue and can prolong the pain and inconvenience of a malicious code infection. If your security software only scan drives and memory, without scanning UEFI, it is possible to think you have a clean machine when you don?t, that?s why we recommend a security solution that scans it, like ESET.

Why does my device have a UEFI?

Computing devices work by executing code: the instructions that we call software and which make the hardware ? such as a laptop or smartphone ? do something useful. Code can be fed to the device in several ways. For example, it can be read from storage on a disk, held in memory, or delivered via a network connection. But when you power on a digital device it has to start somewhere (bootstrap), and that first piece of code is typically stored in a chip on the device. This code, referred to as firmware, may include a ?power-on self-test? or POST to make sure things are working correctly, followed by the loading into memory of the basic in... Read more

A year later, and I discover again that I STILL cannot boot from a non-UEFI CD on my UEFI Win 7 Pro SP1 64-bit Dell Optiplex 7010 MT even though "Enable Legacy ROMs" is ENABLED in the BIOS and Secure Boot is OFF.

My original details are here - Cannot boot from CD-DVD in LEGACY mode - NOT Secure Boot NOT UEFI - General Hardware - Desktop - Dell Community

That thread from a year ago describes the issue but then goes off on a tangent into my (successful) experience in establishing dual-booting, but THIS ISSUE remains. My Dell Optiplex 7010 MT (which is now dual-booting Win 7 Pro SP1 64-bit and Win 10 Pro 64-bit) will NOT BOOT a legacy CD that is not UEFI even though "Enable Legacy ROMs" is CHECKED in the BIOS and Secure Boot is OFF. (My BIOS is A20.)

What is the fix??

Please reply here, not in my old Dell thread above. Thanks.

Update - I have now made TWO bootable CDs of Macrium Reflect. These two CDs show the problem.

First, in my old Dell Optiplex 755 Win XP Pro SP3 32-bit machine, I installed Macrium Reflect Free and made a bootable CD with the included Win PE. I assume it will boot in my XP machine. However, that CD will NOT boot in my other PC, which is my Dell Optiplex 7010 MT that dual-boots Win 7 Pro SP1 64-bit and Win 10 Pro 64-bit, even though the BIOS in this Dell Optiplex 7010 MT ENABLES Legacy ROMs.

Second, in that other PC (my Dell Optiplex 7010 MT that dual-boots Win 7 Pro SP1 64-bit and Win 10 Pro 64-bit), I again installed Macrium Reflect Free (with 64-bit architecture) and made a new bootable CD (with the lowest level of Win PE, which is 3.1), and that CD WILL boot in that second machine.

Why are we being tortured this way? I have other bootable CDs from my XP days - is there any way to get them to boot in the second (Win 7 Pro 64-bit) PC?

Thanks.

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!

A: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.

Hi everyone
Some people might like to test the possibilities of UEFI systems even though their current machines aren't equipped with it.

It IS possible to do this in a Virtual machine even if the HOST system is a non UEFI machine.

Edit Manually the VM configuration for the VM you want to test this feature with.

Add the following like to the .VMX (machine configuration file)
firmware = ?efi?

Note that you must do this BEFORE installing the VM and you can't change it afterwards.

Cheers

There were no post reactions back there but I guess those who need this can easily and silently test it out.

You've mentioned it:

Very important indeed because we know how easy it is to change settings on the go; unfortunately this settings aren't meant to be changed afterwards.

Hi everyone, my new laptop has a normal hard drive and also has a 128gb Samsung m.2 ssd drive.

I was able to install a fresh dual boot on the regular hard drive. First Windows 10 then Windows 7 using usb method which included embedding the usb 3 drives.

Now for the ssd I shrink down half the drive after Windows 10 was installed so I could install Windows 7. Followed pretty much the same process, booted with Windows 7 usb got all the way to the partitions and Windows then said "Windows was unable to create a system partition etc." message. I did have the option to continue, which I did as stated in one of the tutorials " this site. However after files installed I ended up getting an error at the end.

So I'm wondering is this perhaps because I didn't burn the samsung nvme drives into the usb?

A:UEFI Dual Boot Windows 10 and Windows 7 x64 on SSD Drive?

- Win 10 use "Secure boot" that isn't compatible with Win 7. You have to set it to Other and Compatible System Mode to enable. As Win 7 was installed with Secure boot=enable, don't know if it will boot with Secure boot=disabled

For Win 7
Under CSM enable UEFI boot.

More or less like this
OS type Windows UEFI = Secure boot, so if OS type = Other, secure boot is disabled.

for CSM, here are the current settings (in bold)
Launch CSM.......................................(Auto, Enabled, Disabled)
Boot Device Control.............................(UEFI and Legacy OPROM, Legacy OPROM only, UEFI Only)
Boot from Network Devices...................(Ignore, Legacy Only)
Boot from Storage Devices....................(Ignore, Legacy Only, UEFI Driver first)
Boot from PCIe/PCI Expansion Devices....(Legacy Only, UEFI driver first)

Boot from the Win 7 installation disk ON UEFI MODE (important).

Install on the large empty NTFS partition

For the updates MS releases SP2 for Windows 7

Yes, you have to load the m.2 ssd nvme drivers. As you already have added the USB drivers, during installation you can add them from a USB flash disk.
If you want to understand how the drivers affect Win 7 installation disk
