BSOD after the restart during the install of Windows 7 Ultimate

[Gelo Reyes]

Good day people,
does anyone here having the same problem after downgrading from Windows 8 Pro to Windows 7? I'm using Asus S550CM notebook with 4GB RAM, 1.3gHZ CPU, NVIDIA GT635M and Core i5. This happens to me everytime I install Windows 7 in my system. After filling the required fields during the installation, the computer restarts then BSOD. Thanks in advance

Back up your files, unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, set SATA controller to AHCI, Hard Drive first to boot, Save changes and Exit.

If you notice UEFI Boot choices in BIOS Boot Priority menu then proceed with UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with. If you don't want a UEFI install you can Bypass UEFI to Install WIn7. This video can help you decide: UEFI BIOS vs. Legacy BIOS - YouTube

Then boot into Windows 7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here. I would use a fresh ISO written with tool in Step 2 as yours is in question.

At first installer screen Press Shift + F10, or enter System Recovery Options to open a Command Box, type:

DISKPART
LIST DISK
SELECT DISK 0 (after confirming Windows 7 target HD #)
CLEAN
CREATE PARTITION PRIMARY
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 wiping the HD and marking Active which overcomes certain install failures.
