Y720. Can't boot usb stick in UEFI to install Win10 in UEFI mode

Q: Y720. Can't boot usb stick in UEFI to install Win10 in UEFI mode

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!

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.)

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

A: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.

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?

Please explain this.

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.

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

So I've searched, and I've tested, and now I'm about to turn my laptop into a frisbee and never buy a Samsung PC again. In short, I bought an ATIV 7 whose previous owner had downgraded to Win7. I wanted to put Win 8 on and I have a volume license as well as the OEM key so I burned the ISO (actually 2 different ones) using every method I could find (ImgBurn, Rufus, Iso2Disc, Win7 Download tool, etc.) It became clear that the USB needed to be formatted FAT32 with GPT filesystem, however in UEFI mode it shows the USB but won't allow me to select it - it just flashes. If I set it back to CSM and UEFI I can make a USB boot, but even if I use diskpart to clean the drive and convert to GPT it will fail to install because it detects I didn't boot in UEFI mode.

Here's the deal. When I'd installed it earlier this week in CSM and MBR mode, and then converted to UEFI it worked fine. So....I tested several recovery programs we use at work to make sure they'd restore it okay via bootable media. Paragon, Aomei, Macrium, Lazesoft - all boot media failed. ONLY True Image 2014 DOES ACTUALLY BOOT in UEFI mode on my laptop. The only thing I can figure is that the way WinPE 5 or 5.1 (whatever it uses) is set up on it agrees with my laptop. So what I was wondering is if one of the geniuses here has any idea how I can modify the Acronis recovery media or create similar WinPE media that might actually boot on my laptop.

THanks for any help!!!

Laptop detects it fine and can boot of it, laptop is old style of bios.

I tried to disable fast boot, disable secure boot, but still its bypassed.

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.

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"
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.

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.

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.

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..

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.

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.

Hi guys, I made a mess installing w10 in legacy bios mode, while I saw already running w8 in uefi mode.
I'm actually on a w10 system with legacy bios mode.
How can I install w10 in uefi mode, if bios won't start the installation of w10 using an usb with iso of w10 mounted in uefi gpt mode?
Thank you

A:How can I install w10 in uefi mode

There is a way you can do this by creating a system image of your legacy bios mode and restoring it to a UEFI/GPT mode. The procedure is well documented in Macrium Reflect which is a free tool for making system image backups and often recommended on this forum.

Hello,

This is my first post here. Just joined TenForums.
I`m having a problem trying to install W10 in UEFI mode. It keeps installing in Legacy mode. Is there a setting that needs to be changed in the UEFI BIOS?
Also it takes too long for the PC to finish POST. It takes more than 2 minutes from start up to Windows screen.

Thanks

BTW, This is a new clean install on a new PC build. I am installing W10 from a licensed disc. I have set the boot priorty to the BD player in BIOS. But, there is no UEFI boot to choose on the BD player drive.

A:Can Not Install W10 in UEFI Mode

Connect only the HD/SSD that you are going to install Windows. Disconnect the restSet BIOS for UEFI ==> disable CSM. Also disable Secure Boot.Use F8 to access boot menu, there are 2 modes to boot from the installation media (USB/DVD). One prefix with UEFI, select it to boot from.Once booted. hold SHIFT+F10 to open Command prompt, type:
diskpart
select disk 0
clean
exitContinue with installation, select Customize, select the unallocated partition (do not format), click next to install...

EDIT: Just noticed that you did not have the option to select UEFI from the DVD. You can download the ISO from: Windows 10 Download
and use: Rufus - Create bootable USB to create a bootable USB.

I received a new P51 Laptop and I'd like to install linux on it (dual boot with Windows). CD/USB boots perfectly fine in legacy BIOS mode. But when I switch to UEFI only (even with Secure Boot disabled!), I can't boot from CD/USB anymore. In the boot menu (F12) the options are shown, but after selecting to boot from CD/USB, the screen goes black and quickly returns to the boot menu. The installation media contains an EFI loader, so this can't be the issue. Further secure boot is disabled. So - to my understanding - it should theoretically work. And I don't want to fall back to legacy BIOS boot. Anyone else experienced this problem? Does anyone have a suggestion on how to solve this issue?

A recent hardware or software change might be the cause.
To fix the problem:
1. Insert your Windows installation disc and restart the computer.
2. Choose your language settings and click next.
3. Click "repair your computer"

Hello,

I am using Windows 8 since release now but just figured out it was never installed in UEFI mode. So I wanted to reinstall it. The first problem I had was I couldnt boot from my DVD I burned the iso file on the Windows 8 setup too created for me, there is no UEFI boot option available.

Then I created a copy of all files on a 8gb SD card, used bootsect /nt60 x:, again, no UEFI boot option available. My last try was, because I have no USB pen, creating a fat32 partition on one of my usb hdds, again copied all files on it, did a bootsect /nt60 x:, and now I was able to chose UEFI: ... from the boot menu.

So I booted from it, but then it gave me this error screen, and I don't know why, or what to do now anymore. Any help would be really appreciated.

So, what is that basically ? When i boot from my usb stick, i have the option to install in UEFI mode and in normal mode.

I know in UEFI mode it makes 4 partitions, and in normal mode just 2 partitions.

So basically if i install in UEFI mode i will have better windows 8 implementation and it will boot and post and run faster ?

What are the advantages for installing in UEFI mode vs normal mode ?

And why in UEFI mode the OS creates 3 additional partitions, instead of only one ?

Hey guys, I've never seen a full guide to installing Windows 7 in UEFI mode before anywhere, trust me I've looked. But I managed to pull it off a few days ago. So I thought I'd share it with you guys

What you'll need:
A Windows 7 64 bit ISO (doesn't matter what edition and can be an All in One disk.)
Virtual Clone Drive (To Extract ISO Contents)
8GB+ USB Stick
A UEFI BIOS
7-Zip
A Computer already running Windows

Steps:
1) Install Virtual Clone Drive Link Here and also install 7 zip Link here

2) Make a flat copy of your windows 7 x64 ISO, which mean just extract the contents of the ISO into a folder. First you'll want to mount the Disk Image, by right clicking and mount to Drive E: for example.
Mounting Image Example

Next open the disk drive you mounted it to, and copy the contents to a place you'll remember. (This will take a while)
When it's done it should look something like this

3) Format your USB Stick.
Just go to computer, right click it and press format. Make sure you change file system to FAT32. This is so you can boot from it.
Settings for formatting

4) Now here's the hard part. Preparing the flat copy for UEFI.

Go to the EFI folder, make a new folder in there called "boot".
Now go into the "Microsoft" folder which is in the EFI foler. Then boot, and copy the contents.
What it should look like
Put that into your boot folder you just made.

Now that's done. Go to the Sources folder which is in the root Here!

I have been trying for days to install Windows 7 on my new Yoga 11s in dual boot configuration with 8.1, with no luck.  Typical catch-22 problem -- can't boot from the install media in UEFI mode, and if booted in legacy mode, Windows won't install on GPT partition. I followed all the steps everywhere mentioned:  disabled secure boot, set boot mode and order in every possible combination, etc.  I followed these steps exactly to create a UEFI-bootable USB drive:http://forums.lenovo.com/t5/Windows-8-and-8-1-Knowledge-Base/Why-can-t-I-boot-from-a-USB-key-on-UEFI... I can boot easily from the USB in legacy mode, but in UEFI mode, when starting the machine, the USB is ignored.  If I go into Windows 8.1 recovery and do an advanced start and choose EFI USB, the machine thinks for a moment and then says: "System doesn't have any USB boot option.  Please select other boot option in Boot Manager Menu." Then I click OK and it offers only one option on the menu, Windows Boot Manager. I don't know if the lack of boot options is just a symptom of the USB not really being UEFI-bootable, or some other steps are needed to add boot options.  I even tried adding an item within the windows boot manager, but that didn't work, because even if it could work in principle I don't know the right settings. Has anyone actually made this work?  If so, what is the secret?

I had the same problem and a lot of frustration. I finally solved the problem by using a different USB key. I also had to go into boot options and select the USB key even though I had the USB key first in the boot order. Right now I am Re-imaging from my backup and pray for success. Although things may look brigth afterall I have to leave out some steam:The whole problem started with a screen error, which had to be repaired. So before sending it to repair I made an image backup, - just in case. I got an eight hour time window where I had to wait for a pickup of the computer,- very frustrating when you are having a job requiring traveling. After ten days the computer computer came back with a scrambled hard disk with at note saying that it was an software error, although it was no doubt an hardware error because it worked perfectly with an external monitor.

Now, I want to install win 7 32-bit on my laptop. But, My CD Win 7 bootable won't boot at my laptop. After i check bios, i found something strange on boot menu orders, if the boot in "Legacy" mode, that laptop will boot from my cd. But if "UEFI" mode, looks like the system has ignore my boot cd, and go straight to windows 7 64 bit. Has anyone solve this problem? Will somebody help me to solve my problem? Thanks anyway

A:if UEFI mode on Bios, Cannot boot from CD... :(

You can install 32 bit to an EFI BIOS but it has to be in Legacy mode, with EFI Boot disk removed from the BIOS Boot order, and the HD wiped with Diskpart Clean Command so installer can reformat it from (EFI formatted) GPT disk to the normal MBR disk.

Or at least I think thats what's happening.

In the past under windows 7 or any other OS you can tell Bios to boot from USB. (or from your version of a quick boot options on system start) I cant do this now. The option wont show. I have read if you disable secure boot and or UEFI mode this will allow the USB to be seen at boot but if you do this you can no longer boot windows 8.

It doesn't make since to me they would force you to have to go into bios and change this setting each time you want to switch from a hard drive booted windows 8 or load a live version of another OS from a USB at boot time - so I must be missing something or not understanding something right.

I have tried asking the HP people and getting answers out of them is worse than pulling teeth. Since this new UEFI thing is windows 8 related, I thought i'd ask here to see if anyone can shed some light.

Hello

Since UEFI exists, some people talk about BIOS replacement by UEFI in short-term (2011 for exemple) (see "News").

Who never has problem with BIOS bugs ? I must fight against several problems on one of my mobos because of its incorrect BIOS code, essentially for long time boot BIOS and very buggy S3 sleep mode.

However, when I read many posts about people who have installed their Windows 7 x64 in UEFI mode, I'm afraid of some new problems that UEFI causes, according to these people, even during a Windows session, even if installation was fine.

I would like to know your experience about UEFI, on motherboards which support it (my motherboard is an Intel DG45ID which proposes UEFI boot).

Thanks

A:Is it right time to install Windows 7 x64 in UEFI mode ?

I think most cost effective motherboards are still BIOS/MBR. I haven't really looked hard but I haven't seen any UEFI motherboards readily available where I am. I'd only jump to UEFI at this stage if I needed > the 2TB limit. 1TB at a time is big enough for me to backup. If the BIOS is playing up can't you flash it to a later version?
