Asus N76 UEFI - W7 64 Install Hangs on Logo (DVD UEFI Boot)

Q: Asus N76 UEFI - W7 64 Install Hangs on Logo (DVD UEFI Boot)

**** This issue has been resolved ****
**** Look at Page 4, posts 4 and 5 ****
**** 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....There are no crazy error messages. It just sits doing nothing. The BR drive spins and then it just stops.

I have attached some screenies of my EFI. It is a brand new laptop.

I'd say a motherboard issue? But then, I have no issues running W8 on it. I just want a fresh install of the OS on the SSD. I have a brand new unused copy of W764 ULT.

Win8 PC's have Secure BIOS which must be disabled to install any other oS, then you can install in UEFI mode following these steps: Downgrade Windows 8 to Windows 7

hi,
i am having a peculiar problem with my newly purchased Acer TimelineU M5-581T laptop. it has 20GB SSD and 500GB HDD and UEFI MB also supports legacy BIOS. it came with Windows-8 pre-installed and had a single drive C:. i needed to partition it and had created drive D: with windows disk management tool by shrinking drive C: and then creating drive D: with available space. problem started to happen after that when i restarted laptop, it was failing to boot on Windows-8 and was going to repair option - eventually that was too failing, but i think i didn't try all the options under repair. i also don't have Acer recovery or restore disks with me, last i got that i should have created the disks before.

since repair didn't work, i tried to fresh install windows-7 from bootable USB containing windows-7 x64 installation.

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.

Let me first address a few things:

- I have read extensively on this topic, using guides such as this to determine whether or not I have bootable media for UEFI, which I do.

- I have both an original, unused Windows 7 Pro w/ SP1 x64 install DVD, connected through the USB 2.0 external DVD burner that was provided by the computer manufacturer, as well as a 4gb USB 2.0 stick that I created using Rufus (the settings are all correct and specified for UEFI/GPT/FAT32 and all that) and slipstreamed with Intel's USB 3.0 drivers for Windows 7 x64. Both devices boot and give me the same result: the freeze at "Starting Windows," where the dots start moving around momentarily before freezing in place.

- Booting the DVD in Safe Mode still gives me a freeze. The last "Loaded:" item in the list is disk.sys.

- I've seen it mentioned that some NVIDIA cards have had issues with UEFI and/or Windows 7 booting/installation, so I tried switching off the "switchable graphics" option in my bios so that my system would run using the integrated Intel graphics (which I would assume it had been doing anyway). Still the same result either way.

- I am not dual-booting, nor do I have any desire to use legacy bios if it's going to stick me in an infinite boot loop like the last time I tried that. My laptop, a Lenovo Y700-15ISK, has no option to use any "UEFI + Compatibility" option--I am only given the choice between one or the other.

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.

It hangs at the motherboard boot logo but doesnt go any further as when it trys to boot to the drive it never moves on. Doesnt even try to load windows, Yet booting to a cd and reloading windows will fix it on the same dirve and connecting any other drive around will allow it to pass this point.

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?

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.

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)

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.

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.

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.

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.

When I access my UEFI during startup, the Boot Priority section is either empty or shows unrelated drives attached. I can select the drive from which to boot by clicking on the Boot Menu, then clicking on the drive desired.

I purchased a new Intel SSD and installed it as the "C" and "D" drives and was happily booting from that SSD until I added new HDDs to my system. I now have four HDDs plus the SSD. One of those HDDs still contains the original Root C bootup and Windows 8 system on it. I frequently now find the system, reason unknown, may choose to boot from the HDD rather than the SSD.

I cannot find the method for directing the UEFI bootup menu/priority steps... my goal is to have the computer boot from the SSD, which if it were to fail, then would secondarily boot from the HDD original Root C.

The computer arbitrarily changes the SSD from drive designation "C:" to "J:" and the HDD to "C:"... how to specify the SSD as the "C:" unless it fails or is removed?

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.

A:ASUS X55A Windows Install + UEFI Confusion

Hi CYPER.

I am not very aware of the UEFI because when I got it and had a real hard time to install windows, I straight disabled it.

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.

   Tip
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 everyone,
I came here for help because I've just bought a brand new ASUS laptop (low-budget) model R540SA (Pentium N3700, 4GB DDR3, 240GB SSD). It came with no OS, as I wanted to, so I turned it on and started installing Windows 7 Pro x64. I thought, yeah it's a brand new laptop, it's gonna be easy and quick and I'll be able to use it in a moment... And I just can't do it. It drives me crazy right now, because hey it's a new laptop! It should work just fine!

I've read all the advices around the Internet (UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with among others) and nothing actually helped. I also tried the method using DISKPART. Every time I try to install Win7 it gives me BSOD when displaying Windows logo after the restart. I can't even check the error number, because it restarts automatically. I think everything in BIOS is set up fine (I made a few photos of the settings (number 2 to 5) - URL is at the end of my post). The only thing I suppose might help is a bootable pendrive. I already tried burning it using Rufus, but when I try to use GPT it says my ISO is not an EFI ISO so I have to change to MBR for BIOS and then it says I can't choose FAT32 with this ISO, so I have to choose NTFS (see photos 6 and 7) and when I try to boot I got this - see photos 0 and 1.

I have an ASUS ultrabook. Being an ultrabook it has a small SSD drive and no DVD drive.

It came originally installed with Win 8 and was later upgraded to Win 8.1.

After a while the system started behaving in very odd ways and I decided to reset from protected OS region.

Try #1 - When I tried to reset I received an error stating that it could not refresh because there were files missing. I read somewhere that you can't refresh using the Win 8 copy after you have upgraded to Win 8.1.

Try #2 - I have a retail copy of Windows 8 on a USB drive so I thought I would just install that. First problem - the key is no longer on a convenient sticker but is, instead, embedded in the UEFI. I was able to find a tool that exposed that only to receive an error stating that I can't use that key with a retail copy of Windows 8. Arrgh!

Try #3 - I have a Dell desktop running Win 8 and used that to create a Windows 8 recovery drive on a USB stick. I was able to use that to run a refresh which seemed to work (it certainly erased all the files) but the system is still not right. For example I can't run Netflix because it keeps telling me I am missing components. I tried installing the components it suggested for Chrome - no luck. I then tried installing MS Silverlight to run it in IE...again no luck, still get the missing components message and the install of Silverlight failed.

I followed the steps here:

But after restart on installation done, the PC cannot boot into Win 8 and I always get the light blue screen with a "Recovery" title stating that the PC couldn't be started properly and an error code 0xc00000001.

Played with the BIOS setting (CSM, Secure Boot etc), switched to onboard graphics, reinstalled a few times the UEFI way.
Also tried the automatic repair but to no avail.
The UEFI installation is always successful but I always cannot boot to Windows.
What different is that the installer always partition the drive to 4 partitions (Recovery, ESP, MSR, OS) instead of 3 in the tutorial.

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.

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!!!

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 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

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?
