Windows 10 UEFI does not boot after clean install

Q: Windows 10 UEFI does not boot after clean install

Hello, I have a problem with booting Windows 10 X64, after installation with GPT, on a HP 8200 Desktop, with 2 HDD in Raid 1.I have updated the firmware to the latest version v 02.29 . Until the update, Windows 10 x64 was installed in UEFI mode and worked ok. I tried to update the firmaware to the last version because i was unable to use WOL for starting up the PC.After disabling fast boot in windows and made different changes in BIOS, WOL turned on the PC but after the boot screen Windows doesn't loads ( a blinking cursor remains in left up corner and doesn't do anyhing). If i try to turn on the PC from the button Windows loads normaly. I recreated the RAID, and reinstall Windows with GPT. After the setup finishes, and the computer reboots, i have the problem that i haved when starting from WOL (a blinking cursor remains in left up corner and doesn't do anyhing). I'ved tried to reinstall Windows changing different settings in BIOS, but it still doesn't boot. I boot from Hiren with the miniXP and i saw the partitons and the content of C:\ and all seems to be ok.I installed Windows in MBR, and with MBR is working fine. I think is a problem with loading the UEFI boot from the RAID.Now i am unable to activate Windows because of "hardware changes" and I want to have Windows installed with GPT. Thanks

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

I have a Slide i701 which came with Windows 8.1 and I used the Media Creation Tool ISO to upgrade it to Windows 10 Home Single Language x86. Yesterday, I downloaded the 1511 Build for the same. I'd like to clean install the build using the ISO and by clean install I mean, I will be cleaning the whole disk with clean all (diskpart) to start fresh. The tablet uses GPT, and I have a USB with the ISO booted with Rufus using the GPT scheme for UEFI.
1. Can I directly clean install by booting the USB like on a PC and then clean the disk with clean all command or do I have to do some additional steps, for eg:- I read somewhere that I have to convert the disk to GPT after using clean all.
2. How to activate after clean install.

Please leave your suggestions, esp. if you have done the same as above on a UEFI Tablet. Thanks

A:Clean install on Windows 10 Tablet - UEFI

The easiest way to do it is not mess with diskpart at all. Boot from the USB flash drive - select the custom install option - delete every partition on the "disk" - select the unallocated space to install to and click next to let Windows set up the "disk" the way it wants to.

It will activate based upon both the Windows 8 product key it finds in the UEFI firmware and the digital entitlement stored on Microsoft activation servers from the initial upgrade.

Before you do the clean install, I would highly recommend you export all the third party drivers using the dism /online /export-driver command.

Hey Guys, I'm still fixated on all the woes of UEFI. If a UEFI Windows 8.1machine upgrades to Windows 10 and at some point one wants to do a clean install of Windows 10 am I correct that the only way to do so is disable secure boot,and enable CSM (legacy boot) or is just disabling secure boot all that needs to be done.? I know the OS tied to the UEFI would be Windows 8.1 so I can't see how a clean install of 10 could be done any other way. If this is correct am I right in assuming that the partition scheme will still be GPT rather than MBR if only secure boot is turned off but, if legacy boot is enabled then the partition scheme would be MBR or can it be either way depending on what installation media one uses?

I have NEVER remained so confused about any issue as I am with UEFI. I wish someone would write a Simpleton's guide to UEFI (using small words) because this simpleton has come to the conclusion that's the only way she's ever going to get it and may not even then. The whole issue of UEFI is crap as far as I'm concerned only making a clean install harder. Don't think that I haven't researched this issue prior to this post. I have-a lot. I just get more confused the more I read.

Hello, Community! I'm about to do a clean install of Windows 7 Pro SP1 64-bit on a T530 (BIOS v2.68) with an SSD. My issue is I'm new to UEFI and have never done an install with UEFI. I suspect that my apporpriate install BIOS Setup should be:UEFI/Legacy Boot: UEFI OnlyCSM Support: YesDoes the T530 support a UEFI boot interface similar to pressing F1 and getting into BIOS? Then after I install Windows 7 then install all the T530 HW drivers, I should set the BIOS settings to:UEFI/Legacy Boot: BothUEFI/Legacy Boot Priority: UEFI FirstCSM Support: Yes Does my above configuration plan make sense? I have two requirements once Win7 is installed - first, I must be able to boot from an external USB when needed. Second I must be able to boot into either BIOS or some UEFI graphical interface (I see on this forum that when some people set UEFI they lose that ability).. Will my above plan achieve this for me? Thank you!

A:Clean Install of Windows 7 Pro on a Lenovo T530 with an SSD - UEFI Issue?

Hello and welcome,
 
I've moved your post to the T-series forum.
 
A couple of quick thoughts.  Others will probably have more suggest.
 
Boot your installer via the USB 2.0 ports.  Clean '7 won't have USB 3.0 drivers and the installer will fall over.
 
If booting the installer from a flash drive you'll have to modify the it for UEFI booting. Don't know about a DVD.
 
F12 will get you the boot menu and on current UEFI machines there will be a tab for BIOS access.  Not sure about the 530.
Depending on what you're going to be booting via USB in the future UEFI-only may be fine.  Doesn't really matter if you leave at "both" but occasionally something will boot in the "other" mode and produce unexpected results.  I'm inclined to leave it at whatever the OS install mode is and toggle as necessary - but whatever floats your boat.

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 have a new Precision 7710 with a 2.5 inch 1GB SATA SSD (system boot=Disk0) and a 1GB NVMe PM951 SSD.
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.

Hey all,

I just got a new HP ENVY dv7t-7200 CTO Quad that came pre-loaded with Windows 8. I wanted to install Windows 7 so I enabled "Legacy Support" in the BIOS which disabled UEFI mode. Everything went fine from there. I ultimately decided to go back to Windows 8.

I've been having some trouble with my existing Windows 10 installation, and I'm planing to resinstall the OS from scratch on a brand new SSD that's fresh out of the box.

I want to install it with UEFI and Secure Boot from a USB, as I'm currently using Bios.

I've installed OSs before so I know the basics about partitions and so on, what I'm not certain about is how I can be certain that I'm installing Windows 10 as UEFI, and not as legacy bios.

Is there a tickbox or an option that you need to select during the installation process, or is this something that you need to select from your MB.

I plan to install from a USB stick. I've already downloaded the ISO and made the stick as I previously upgraded from Window 7.

Ak

A:UEFI without doing a clean install?

I don't think that is possible without another clean install to set the proper partition structure for UEFI. However, I don't quite understand where the new hard drive fits in? The way I see it, you need to setup your BIOS for UEFI , select the UEFI boot option for your CD/DVD (in the boot menu). Once done, you can simply reinstall Win 8 (using the UEFI CD/DVD option) and make sure you delete all existing partitions as part of the process. So, once your hard drive shows 100% unallocted, simply click Next and the instllation process should create the proper UEFI partition structure.

If you are installing Windows 7/8/10 from a USB flash drive in UEFI Boot Mode, then you need to have a UEFI Boot Mode compatible Windows 7/8/10 USB flash drive.

Here is more info: UEFI Boot Mode (installing using the GPT partition style) and Legacy BIOS Boot Mode (installing using the MBR partition style). -> link

Asus motherboard with UEFI firmware. How to install Windows 7/8/10 64-bit in UEFI Boot Mode.

You do not need to change the default UEFI firmware (BIOS) settings.

Note: You need to select to boot from the UEFI type (marked UEFI in the boot menu) if you want to install Windows 7/8/10 64-bit in UEFI Boot Mode (see screenshot below).

Note: You do not need to change the boot order of drives in your UEFI firmware settings.
- Connect your Windows 7/8/10 64-bit USB flash drive (Note: FAT32 file system) or insert your Windows 7/8/10 64-bit DVD.
- Restart the computer.
- Press the correct key to enter the boot menu (for example, Asus F8 and Gigabyte F12).
- Select to boot from the "UEFI: USB/DVD device name" (see screenshot below).

If you are booting from a Windows 7/8/10 64-bit USB flash drive in UEFI Boot Mode, then UEFI firmware run \efi\boot\bootx64.efi file. Note: This file does not exist by default in the Windows 7 installation media, so you need to create this file by using the Rufus program, if you want UEFI Boot Mode compatible Windows 7 64-bit USB flash drive.

Hello!
I've been reading for a while, but decided to become a member only day before yesterday to post being unable to find solution. I do apologize in advance if this is a dumb question or answered earlier

I would like to nuke system for clean install. I understand there will be system reserved partitions, however, my main concern relates to OS and DATA partitions - Please review attached screenshots and advise



150 GB for C (OS) drive?
30 GB for RECOVERY?
Remaining for DATA?

I am unsure where did I read RECOVERY should be the last partition - how would this be accomplished?

Thanks in advance for prompt response

A:Partitioning UEFI enabled system for clean install

I would have to ask you to be more precise about exactly what you want to do.

For instance, if you are going to wipe the drive and start over by installing Windows 8.1 by yourself, you really do not need a Recovery Image partition (last one) because you will not have a factory image to place in it.

You have to be careful when pre-partitioning. It can be done, but if not done correctly, you will get error messages about not being able to create certain partitions.

A Recovery Image partition is normally just a little larger than the image placed in it. It is created by creating a partition, like the OS partition, and then shrinking it to allow unallocated space for that partition.

The other partitions, Recovery Tools, System, MSR, and OS are created automatically by the install, and these are the critical ones you have to be able to create if you do it manually.

The actual sizes of your OS or Data partitions will depend on how you use your system. A 150 GB OS partition would work fine for me, but you may want to install programs which take more space.

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?

3. Downloaded Lenovo One Key Recovery ISO (OKR8 ISO) and installed it. Now the one recovery seems to work - at least the screen comes up but there is an error when I tried to do recovery - error code 0xe0ef0050

4. Created a Windows set up USB using my friend Enterprise DVD and overwrote the Install.wim file using the Install.wim that I got from the recovery partition (had to split the image into swm files) but it didn't work. It said the product key doesn't match with the image (I didn't enter any product key anywhere)

The title of this thread was too descriptive to fit within the character allotment...;) Here's what I would have titled it had things not been truncated:

Installed UEFI 8.1 (clean) boot partition alongside 8.1 Legacy boot installation in the same system!

Here are some comments...

*My system at home consists of an MSI 970a-G46 motherboard running on UEFI version 2.5 (the latest.)

*Already have a decent 8.1 Legacy Windows install in place, but wanted to add a pure UEFI 8.1 installation from my developer 8.1 upgrade iso but found myself without a USB drive of sufficient size to hold all of the Win8.1 installation files.

*But I did have an extra 320GB SATA II hard drive lying around and I thought I'd try and do my UEFI OS installation from a spare internal SATAII drive instead of the recommended USB drive device.(The size here is arbitrary in that it was all I had...;)A ~150GB drive would work fine, too--you just need enough room for the UEFI install partition and the UEFI Windows installation itself, plus any utilities and things you might like to include in your boot partition.)

*First thing I did was wipe the 320GB drive completely, of course, convert it to a GPT drive (from MBR), create a ~4GB partition, format it to FAT32, make it primary and mark it active, assign it a drive letter (H:\) and then copy over all the Win8.1 installation files from my developer iso. The remaining ~316GB of drive space I left as unallocated for UEFI 8.1 to install into. I als... Read more

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!

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 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.

Windows 10 already utilizes GPT partitioning....on a clean install. The only thing you would need to do is change your BIOS firmware from Legacy BIOS to UEFI BIOS. You will need to confirm that in your BIOS. Or to check with in windows.....in the search bar of cortana, type system information and when the window pops up, scroll down to BIOS mode......here's mine.

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?
2. If I download the legitimate iso fr... Read more

Hello everyone
I am trying to make Windows 10 scripted installation with UEFI boot.
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. 
Here comes the tricky part I can choose my newly created Windows 10 boot source with Dell's own WINPE10 drivers. Then it loads the Boot source file that I created but It stop at the Windows 10 logo it never loads the deployment menu like in legacy mode, so I cannot deploy a scripted installation.
I am stuck what could be wrong or what have I missed ? Please help

I re-installed Windows 10 on my girlfriends pc and now it won't boot, it goes to a recovery screen as shown below:



I installed Windows via USB with the Windows 10 media creation tool. When I got to the screen when I chose the partition, the SSD which I wanted to install Windows on had a message "windows cannot be installed on this drive" so I clicked format, but it had the same message. So I Googled this as I haven't had this issue before, and found a solution to manually wipe the drive and convert to GPT as below:
Open the diskpart tool:
diskpart
Identify the drive to reformat:
list disk
Select the drive, and reformat it:
select disk <disk number>
clean
convert gpt
exit
Close the command prompt window.
Continue the Windows Setup installation.

I followed these steps and windows installed normally, then when it went to boot I got the recovery screen.
I have tried several solutions found from googling but nothing has worked:

Select option to repair your system instead of installing.
Go to command prompt (in advanced options) and hit following commands to repair MBR.
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
Press [y] when system asks you to accept.
Exit

Running start-up repair didn't work either.

I've tried formatting the drive several times and re-installing windows, same issue every time.

I don't really know what to try next. Any help please?

Hi,


I previously had XP32 running from the first partition of an SSD.
I cleaned off the second partition, shrunk it down to 90GB, TRIM, and performed a clean install of W7-64 onto it. I allowed it to install only essential security updates during installation.
Now at boot it produces the message: NTLDR is missing, Press Ctrl+Alt+Del to restart


That is interesting because NTLDR is used to start XP, not W7.


Only when I boot with the W7 installation DVD in the drive, it boots correctly into the Boot Manager and gives me a choice of W7 (default) or XP.


I have gone searching for solutions, and here are the remedies that I have tried so far:


1. the W7 partition was not set as Active, so I set it as active. No change.
In Computer Management the W7 partition is now shown as Healthy, Boot, Page File, Active, Crash Dump, Primary Partition. The XP32 partition is shown as Healthy Primary Partition.


2. I booted from the install DVD, went into Repair, and selected the Repair Boot Config. The installer, however, could find no problems with the setup. I did this 3 times as someone wrote that was necessary. No change.


3. In the Bios, I had the boot order set as Removable, CD/DVD, Hard Disk. Someone said that they had success in solving this by making the Hard Disk the first boot device. So I changed the order to Hard Disk, CD/DVD, Removable. But it did not work. It just went straight into the NTLDR error. So I changed the order bac... Read more

I have had the exact same result with Win7 final RC as well as Win7 Ultimate install attempts. The hardware is brand new Asus 785 Chipset mother board (Kit from AMD/Microsoft Seminar with Win 7 Ultimate NFR) with AMD Phenom II x4.  I've got Win XP 64bit running just fine on this system using  another HD  as a test of the entire system. Only a single hard drive is connected during the testing and install.  DVD boots up fine and begins to intall Win 7 64bit. Then when it attempts very first re-boot during the installation it hangs. I've swapped out hard drives -with no change in outcome.  There is no question that the motherboard, RAM, DVD drive etc. are all working fine. This must be some weird compatibility problem.  I have attempted the installation 3 times with Win 7RC and with the working final release of  Win 7 Ultimate  4 times -with the same hangup on the first re-boot.

A:Windows 7 does not boot from first restart during clean install

Problem is solved. I found the answer on another forum from a posting by WHEST: http://www.sevenforums.com/hardware-devices/34790-windows-7-cannot-see-hard-drive-during-installation.html
  Relevant answer is here:

Firstly, if you have it set in the bios to boot from the cd/dvdrom it can cause installation to loop after the first reboot, as it restarts installation and loops - to fix you remove the install dvd during reboot, or go into the bios and reset it to boot from the hard drive first - so you need to remove the dvd while its rebooting quickly - you have 15 secs to do so before it restarts if you don't hit a key, or go into the bios, and reset it to boot from the hard drive. You have to be watching the last part of the install and be ready to pull the DVD out.  I also hit the Del key so I could reset the BIOS Boot setting. For all other Win OS I have set CD/DVD to be the first boot device followed by the HD, but of course the Geniuses at Microsoft had to screw this up and create headaches for some of us.  Logic and prior experience will not have helped you figure this one out. Keep in mind that it is helpful to assume that MS has done something really dumb. Then you will be on the right track. I consider this a first class BUG. Will Microsoft pay me for the 8 hrs I wasted trying to solve this ridiculous stupidity? I doubt it. So, it seems to me that when you install Win7 you must not have DVD as your first BOOT device, and simply hit F12 (on most hardware) in o... Read more
