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

wim said:

Did clean the dvd allready. Also used an external dvd drive. I'm out of options. I guess i'm going to bring the laptop back where I purchased it.

I did some searching and I discovered this. See photo.
When in disk managment I went to OS C: properties. Then properties of disk and then tab volumes. There is nothing there. The SSD disk has info. Its has partitionstyle MBR. The normal HDD I first have to tick the box fill in so the info appears. I was forced a restart. Does this make sense?

CSM is not need as your Pre-installed Windows 7 is installed in Legacy mode already & booting.

It was a dual boot with old win7 on the HDD and a new win7 on the ssd. I used an upgrade version of win8 over the new win7 SSD. The old version of win7 still was there. Does Win8 change the way the disks behave?

1) The thread is about downgrading from Windows 8 Pre-installed to Windows 7.

2) Dual Boot Installation - Windows 8 and Windows 7 or Vista

3) Is the Windows 7 Pre-installed, installed in UEFI mode?

Try booting the Windows 8 Upgrade DVD.

That was what I also thought, but the plan was to install it on the SSD. I'm going to try it. I will report later. Thanks for all the time you invested. Greatly appreciated!

Unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, save changes. If an EFI BIOS, enable Legacy BIOS or Compatibility Support Module, set DVD drive first to boot, HD second. Then set SATA controller to AHCI. Save changes and Exit.

Then boot into Win7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here. The disk you have may be dirty or defective.

At first installer screen Press Shift + F10 to open a Command Box, type:

DISKPART
LIST DISK
SELECT DISK 0 (after confirming Windows 7 target HD #)
CLEAN
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

Next click Install Now, then Custom install 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.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt.You are creating the partition here for the purpose of marking it Active which overcomes certain install failures.You are trying now to install Win7 to the SSD, correct?

Boas pessoal,
Comigo funcionou assim, entrei na bios, desactivei a opção secure boot no separador security, activei a opção launch csm no separador boot, gravei, reiniciei, carreguei na tecla para aparecer o menu de escolha de boot ( no meu é a tecla ESC ) e logo apareceu para escolher, pen, dvd,disco, etc...

Hello everyone,
With me it worked this way, in my bios e disabled the secure boot option in the security tab, i enabled the launch csm in the boot tab, saved and exit, and then i pressed the ESC key (wich is my key, yours can be diferente) and it show me, the ÛSB boot, DVD boot, HDD boot, and that way i manage to install the win 7 via a USB 3.0 drive.
Thanks to this fórum, in the page 4 on the 4th post.
Sorry for my bad english. From Portugal.

Hello all.
I have the same issue attempting to install Win 7 x64 on a Win 8 x64 pre-installed laptop. The laptop MEDIONshop Nederland | MEDION AKOYA E7221 laptop is equiped with 2 HDD/SSD drivebays and has excellent driversupport, including Win 7 drivers.
I felt it would be much more responsive running Win 7 from a SSD so bought the new Samsung 840EVO 120GB for that. Still had a WD Scorpio Blue lying around for data utalising the second drivebay.
The original HDD I took out just in case the laptop ever has to go back in factory conditions.
Then of course I ran into the same problems OP had.

Since the AMI bios also has the launch CSM and disable secure boot options listed, I now feel confident the transition will succeed.
Will let you know how I'll get on. Thanks in advance, best regards Bart.

Yes, a Win8 PC needs to have Secure Boot Disabled in BIOS setup as shown in Downgrade Windows 8 to Windows 7.

Or if this presents problems you can Bypass UEFI to Install WIn7.

I'm having this exact same problem on a Dell Precision T1650. When legacy options are disabled, the Windows 7 installer hangs on the splash screen before ever loading the installer. I can install fine if it's Win 8 or if legacy options are enabled. I can't use legacy options though like the original poster. I need the OPROM free for a RAID controller I'm installing. Any ideas how to get this to work without using legacy?

Are you getting an EFI listing for your bootable installer when you boot in to choose it, as shown in UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums.

If using a flash stick did you follow the special steps for UEFI Bootable USB Flash Drive - Create in Windows ?

I fixed this problem for myself. LSI said the card needs to have the OPROM available, which is the resource Windows needs and gives the error code 10 on. When I switched to UEFI mode and left legacy option roms available it still wouldn't work. When I switched to UEFI and then turned off legacy option roms then it worked. I have an Optiplex 790 sitting around which is basically an older T1650 and the bios on that machine didn't have the option to turn off legacy boot roms. I could switch between UEFI and legacy boot mode, but there was no option to turn off legacy roms. In the T1650 bios, there is an option for switching boot modes and a seperate option for disabling legacy option roms. The two are distinctly different. It's possible you'll only have the option to switch between boot modes, in which case the bios may still have a handle open to the legacy option roms, even though you've switched to UEFI boot mode. If that's the case, look for a bios update (the 790 had the most up-to-date) and hope that will give you the option. Otherwise I don't believe there is anything you can do other than get a new card or a new motherboard.

You said that you'd disabled Legacy Options in BIOS. Disabling Legacy Mode or CSM choices should be sufficient to enable UEFI install.

That's why I asked if you have UEFI boot choices for your installer. Did you try the UEFI DVD boot?

You'll always have to choose your boot device when installing, using either the BIOS Boot Priority order choices, or the one-time BIOS boot Menu key at boot.
