UEFI boot keeps changing; UEFI/Win7 handshaking confusion

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

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.

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.

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.

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!

**** 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:

SEL DIS 0 (after confirming Windows 7 target HD #)
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)

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 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!

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

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

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.

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

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

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.

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

Hi, I am using a Lenovo Y50-70 Laptop. Lately, I installed a Samsung Evo 850 SSD and made it a dual boot with Windows 10 and OpenSUSE Tumbleweed. After few months I tried to install another operating system but any kind of USB bootable device is not recognized by the system. I tried resetting the BIOS settings removing the battery and it didn't work. So as an experiment I removed the SSD and reinstalled the HDD(with the operating system), and then I did reset BIOS settings again. HDD is detected by the system, it is displaying in the BIOS settings, but the boot entries from SSD is still visible and boot entries from the HDD are not detected. Please help.

This is somewhat of a follow on to my earlier post dealing with migrating the OS to an SSD.  After havinig cloned the OS from the 2TB HDD, I wanted to boot from the SSD.  In the old days I would have gone to BIOS and from there selected boot priority of the various devices.  In this instance, I encountered UEFI and could not figure out how to change boot priority.  I saw options for legacy boot, some messages about disabling secure boot, and I was afraid to touch either.   So....I just swapped the disk cables and booted from the SSD.  
Still, I have the question, how can I change the boot priority?  Is there some Dell manual that gives a good explanation of the UEFI interface for me to study?

Heys guys, I'm hoping I can get some help with this. I have a Lenovo y410p. It has 2 drives, one with the OS (120GB SSD 40mm N.2 NGFF) and a data drive(1TB HDD)
My computer recently crashed when I was installing a piece of software, (Bentley MX Road, it's a road alignment package.) When I restarted my laptop I was greeted with a lovely message informing me that winload.efi was corrupt. That was fine so I did a bit of research to fix it involving getting a recover DVD and going to the command prompt to rebuild BCD. That didnt work for me as it didnt detect windows. I tried to see what was up with the SSD using DISKPART & CHKDSK. Neither of these showed the SSD. They only showed the HDD
So now to take a step back, In order to get the recovery DVD to boot I had to change the boot option in the BIOS from UEFI to legacy support. This showed me a list of bootable devices (HDD, SSD, DVD etc.) When UEFI is selected only one option is available which is the Windows boot manager. This is followed by the serial number of the HDD which does not have any OS on it.
I have tried using f12 which give me the windows boot manager option and nothing else. When I select this, it boots me into the error message.
So to get to the root of this, how can I change the boot order when the BIOS is set to UEFI so I can repair the winload.efi file on the SSD. Thanks for any help.

You change it the same way as before. Usually you can do it withe the OEM software installed on Win8.

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.

Following the crash of my old system due to hardware failure I recently put together the computer I am currently using, the following are the specs and I will get into the issues I am having following.

CPU: AMD FX-8350
Memory: 8gigs
GPU: SAPPHIRE Radeon HD 7870 GHz Edition

The issue that I have been having is that following a clean install of windows 7 I attempt to upgrade to windows 8 and am halted differently depending on my install method. To begin with, upgrading from the desktop seems to work at first and upon restart I get a windows 8 logo screen, followed by another restart with a blank screen. The system them goes idle and nothing happens.

Upon further investigation, the UEFI settings appear to be the cause of a lot of the issues I am having and as such I create a USB drive to install from. I am able to begin the setup, and after deleting all partitions I am able to set up the drive with a new partition system in GPT format.

Here the system copies the files, expands the files and seems to install everything normally. It reaches the restart portion of the install, and after taking out the USB stick it restarts. From here it loads up a windows 8 logo screen with the dancing dot circle at the bottom, and after a while it will restart again. It loads back into the same dancing dot circle for a while and once again restarts.

However, this time it restarts into a blank screen, and after a little while the HDD stops working and ... Read more

Can someone elaborate on this UEFI thing as I am totally confused.
There is an option in the BIOS that says: Delete Boot Option, but there is nothing to delete. There is also no Add Boot Option.
Also there are supposed to be other options such as Launch CSM or Secure Boot Control, but they are missing too.
There is no UEFI option too. There was one with BIOS version 302, but I updated to latest BIOS 417 and it was gone.

My attempts to install Windows 7 fail miserably and I don't know why. The weird thing is that if I disable USB via I/O Interface Security then Windows 7 loads after a fresh installation, but if they are enabled it gives me a BSOD with 0x000007E error. Tried to install Windows 8 and at one point it was working, but then I installed a bunch of drivers and it started giving me a fancier BSOD. I think the Intel Rapid Storage Technology driver was to blame?

So what is this UEFI thing and how do I use it to install Windows 7 or 8 properly? What options do I disable/enable in BIOS and at what point?

Thank you.

I think some other people will explain you about the UEFI, but my concern is the BSODs, stop 0x7E, caused by Intel Rapid Storage?

You may boot into the BIOS, and then disable Intel Rapid Storage and/or Intel Smart Response. Also if there is a xTreme Hard Drive (Gigabyte XHD) option, keep it disabled.

One more vital question is ..... you have two discs. Definitely you are installing windows on the OCZ SSD? When UEFI is on, the disc will be formatted as GPT during install. But what is the format of the Samsung HDD? If it is MBR, windows will never load. If you know about it, let us know.

But if you dont know, download Partition wizard Bootable CD (the last one in the link). Burn it in a blank CD or in a USB flash stick.

Boot into Partition Wizards GUI following this instructions. When you are on the last screen, take a camera snap of the screen and upload the snap here.

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

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.

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.)

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?

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.

Add the following like to the .VMX (machine configuration file)

I am swapping out my older X58 BIOS motherboard for a UEFI motherboard with a new Ivy Bridge i5. I'd rather not have to reinstall Windows 7, and just want to make sure I can swap the boards and CPUs without issue. Thanks!

A:Changing From BIOS Motherboard to UEFI

I don't know how likely that is.

Before you try any transplant, I strongly recommend that you image your HD. I've used Acronis True Image, although it's not completely foolproof.

You may be able to simply swap motherboards, Windows 7 detects the hardware changes, and off you go. You may have to install a few new drivers.

If that doesn't work, you may be able to use the sysprep utility on your WIndows installation, with the "generalize" switch. That's intended to allow producing a generic Windows installation for diverse hardware. (Drivers are removed.)

If all else fails, re-install Windows. I hope that you aren't using an OEM copy of Windows. Microsoft may not be willing to activate it on a new system.

I had a successful windows 7 installation on a Samsung spin point in UEFI. I recently purchased a crucial SSD and went to reinstall. When I go to install now it is installing in BIOS mode not UEFI.

Here are my steps:
Booted install media in UEFI mode
converted SSD to GPT using Diskpart and verified
Selected the SSD to install
Finished install

When it is finished it boots windows 7 in BIOS mode and the SSD has been converted back to MBR. I am not changing any of the steps that worked successfully for me before so I am not sure what is going on.

The only thing that I think could be happening is that in the UEFI bios there is still an entry in the boot order for the windows boot manager even though that HDD is no longer in the system.

How do I remove the Windows Boot Manager entry from the bios or how do I completely clear the bios of all boot information?
(I don't care about any of my setting in the bios as I have them wrote down and can just go back in to change them.)

A:Win7 reinstall UEFI problem

The easiest way to reset BIOS is to power down, remove the power cord. Open the computer and remove the CMOS battery. Press and hold the power button for 10-15 seconds to let all the caps drain.

Put the CMOS batery back, connect the power cord and power on.

You should get an error message about CMOS check sum or parity error, press F1 to enter Setup, F2 to continue, or something like that. Go into setup, change CMOS settings, save and exit.

In order to take my win 8 laptop and install win 7, I had to go from UEFI to MBR. Through research I'm hearing that win 10 will be a bit more MBR friendly as opposed to the (even more) anti-social UEFI.

A:Need advice on MBR vs UEFI signatures, consider going win7 to 10

UEFI is the new replacement for BIOS so I would install to UEFI by turning off CSM or Legacy Mode in BIOS and booting disk as UEFI device to delete all partitions so it resets disk to GPT.

I don't know if Linux supports it however.

If you're happy with it and not curious about new features you're missing then you can however stick with Legacy BIOS which works fine for 10.

(A large portion of my issue and what led up to it resides here)

I know barely anything about boot managers and whatnot. This is a part of a long series regarding other problems I've had that I posted previously here a while ago, but no one seemed to know anything about it (although the above link is to another forum).

Well I had gotten past that original problem by forcing the "UEFI DVD drive" to be booted instead of the "BIOS DVD drive" version, as I have the option to pick either type (as to utilize a GPT format instead of an MBR format, I do have a UEFI motherboard by the way). As I try to install Win7 x64, it creates the GPT disk and MSR and EFI partitions correctly, but when the setup restarts for the first time, inbetween the "Installing Updates" phase and "Completing Installation" phase, it gives me this error:

Windows could not finish configuring the system. To attempt to resume configuration, restart the computer.

I tried to manually create the GPT disk and EFI, MSR and primary partitions but no change. I tried different permutations of boot orders and nothing changed. Now, I can successfully install Win7 via the "BIOS DVD drive" and use a MBR style disk instead, and it installs fine. The only caveat is I can only boot up Windows in MBR format if I have the installation disc in the DVD drive, which is silly, and refuse to settle for.

My Win7 is installed on an Asus M5A97 UEFI board with latest BIOS from 10/12. Win7 was cleanly installed this week (after a disk failure BTW). I could tell, when entering BIOS and selecting to boot from CD, that the DVD was listed as a UEFI boot disc. So, I assumed that the installation would install itself as UEFI.... but is that what really happened?

I followed the instructions for using MSINFO32, looked for the line BIOS MODE... it was not listed at all. Weird. I ran the same MSINFO32 with admin privileges, same results.

BIOS Boot order displays a UEFI Windows Boot Loader. Drive C:\ consists of three system partitions on a GPT disk. However, based on the LACK of information from MSINFO32 I am not sure if Win7 is UEFI, or Legacy.

Hello everyone,

I made a post about this over on the Tom's Hardware forum also, but I think this might be a better place to ask.

I'm trying to install Windows 7 from a USB stick onto a small partition (100GB) of a 4TB HDD for an HTPC. When I first tried to create a partition during the windows install, it made the 100GB partition I wanted, but it also split the remaining HDD space into 2 different drives. After some reading, It seemed like the problem was that the drive needed to be formatted/partitioned in the GPT style rather than MBR (in order for windows to accurately see the full 4TB drive).

So, I created a boot disk with the program Parted Magic, formatted the whole drive with the GPT format, and created my 100GB partition in NTFS. Now when I try to install Windows 7 on the partition, it says, "Windows cannot be installed to this disk. The selected disk is of the GPT partition style." And this is essentially where I'm stuck...

I've tried updating my UEFI firmware, and playing with various settings (turning safe boot off/on, changing legacy support options, etc...) but nothing seems to work and/or I just create new issues.

At this point, I'm in way over my head. Does anyone have any idea how I can fix my issue? Any help will be greatly appreciated!

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...

Initially when I first installed Win7, it created 3 partitions, ESP, MSR, and the OS. However do to some glitches with dual booting, I had to delete both OSes and start again.

When installing Win7 now it is no longer creating the 3 partitions, just 2, MSR & OS. I am trying to get it to create the ESP partition. The hard drive is GPT.

A:Win7 installation on UEFI system issues

You have to boot the DVD in the UEFI mode. If you have an F key to give you a boot device menu, use that. If not, go into the bios and select the UEFI DVD entry.

Did you install Ubuntu as UEFI?

But a GPT drive has a hidden partition, which you say it created earlier. If the drive is already GPT, it does not need to be recreated. It might only create a EFI and OS.
I tried several different ways to show only 2 partitions, but even when I preset the drive to GPT, it still showed a 100 MB, 128 MB, and OS.

UEFI can install like MBR in that it may use a single EFI partition for both UEFI installs. So installing with one drive disconnected might be beneficial, but your choice
