Thank you




info: I have created D: partition afterwards, since I wasn't able to do so while in installation process, but as far as I know thats normal.

1. Formated USB to bootable UEFI
2. Set USB as first in boot priority, BIOS second and Windows last.
3. Disabled Fast Boot and Secure Boot Control.
4. Enabled USB Legacy Support, Launch CSM, Launch PXE OpROM.
5. Followed Windows installation instructions, recreated disk partitions, finished installation.

Thats what I've done.

Looks good. How is performance? You can try Fast Boot again to test the difference.

Will this work for my Asus X550LA-SI50402W laptop? I could not get into the BIOS by just pressing F2 at POST, according to their eManual. Thanks.

Boot into BIOS setup, if this is a new Win8 PC look for a setting to disable Secure Boot. Then enable Legacy BIOS or Compatibility Support Module (CSM). This should remove any EFI Boot Disk from BIOS Boot order. Set DVD drive first to boot, HDD 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 OS version here.

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

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

Next click Install Now to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

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.

The purpose of creating the partition above is to wipe the HD and define an Active partition which resolves most install failures. Afterwards you can adjust the OS partition size in Disk Mgmt, create other partitions as desired.

Can you boot into Windows 8? If so you'll need to Boot to UEFI Firmware Settings from inside Windows 8 in order to access the settings you need to change - which will be at least disabling Secure Boot on the Security tab.

Once you've saved that setting, boot via Startup Options Menu - Boot to in Windows 8 into the Win7 installation disk

Then select UEFI DVD drive to boot the disk, delete all partitions during the booted install, create New as you wish or just click Next to let Win7 format an install partition. Clean Install Windows 7

If using flash stick install with a verified ISO image, the stick should be formatted using Option One of UEFI Bootable USB Flash Drive - Create in Windows then choose stick as a UEFI device in same boot menu.


If you receive any errors or failure please report back exact wording and/or behavior.

Thank you for your instructions. I forgot to mention I have the Windows 7 install on a bootable flash drive.

The first time I tried to run the install, I think the OS error said the digital something could not be verified. What does that mean?

It means you should follow the steps I just gave you exactly and report back results.

If you haven't yet disabled Windows 8 Secure Boot in BIOS then you are not going to install anything except Win8.
