Windows 7: Cannot install windows 7 "partition error" microsoft solution not work

Cannot install windows 7 "partition error" microsoft solution not work

Hi,

I am unable to install windows 7 onto my computer. When going to custom in the installation menu and selecting the partition and then pressing ok/install the following error message comes up:

"setup was unable to create a new system partition or locate an existing system partition. See the setup log files for more information."

I have tried deleting the partitions and formatting them and not formating them and many other things.
I have tried the microsoft solution which is to delete the partitions and to just install on that "unallocated space"

What can I do?

Many Thanks

Unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, save changes. (If an EFI BIOS you'll need to decide if you want UEFI BIOS vs. Legacy BIOS: if UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with, or enable Legacy BIOS or Compatibility Support Module to proceed with normal install.) Set DVD drive first to boot, HD second, set SATA controller to AHCI, Save changes and Exit.

Then boot into Windows 7 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, 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 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.
