Hello everyone,

A few days ago i decided on completely reinstalling everything on my computer, but as you can see in the title, i have a problem within the installation of Windows 7. Everytime i try to install it from my USB Flash Drive, i manage to get as far to select wether to upgrade or custom. I pick custom, as all old files have been wiped, but upon selecting my drive to install it on, it gives the error of not being able to create a system partition, and is unable to find an existing one. This happens both when ive created a new partition and formatted it, and when i leave the drive on unallocated space(preffered method)

All other hard drives have been unplugged, and im installing from an USB 3.0 flash drive in a 2.0 port, and all excessive USB devices have been pulled as well.

Ive tried using a method through diskpart, but that failed.

DiskPart <ENTER>
list disk <ENTER>
select disk 0 <ENTER>
clean <ENTER>
create partition primary align=1024 <ENTER>
format fs=ntfs <ENTER> (Will Take a While)
assign <ENTER>
active <ENTER>
exit <ENTER>
exit <ENTER>

Thanks for the help, but sadly, the error still remains. It still fails to create or find an existing system partition

Then where do you get the error when running the Diskpart commands? Be specific.

Next test the hard drive with the maker's HD Diagnostic
extended CD scan to know for certain its condition.
 
No no, the diskpart commands are all working, but upon reinstalling windows it fails, where you have to select where to install it.

*edit: i had already scanned with HDtune pro, and the device is looking fine, nothing out of the ordinary

How did you determine if you have a UEFI BIOS or not? Is there a boot choice for UEFI when you boot flash stick?

How did you create the flash stick and what was the source of the ISO. Confirm the ISO and try writing a new stick from Step 1 of Clean Reinstall Windows 7
 
Motherboards manufacturer page, Motherboards - F1A55-M - ASUS
It states it has UEFI BIOS, no choice to boot as UEFI however, upon hitting f8 (boot location select) it just prompts for location.

I created the USB using the recommended program rufus on here, as for the .ISO, i cant remember. theyre long standing .ISO's i havent had problems with before.

Then this is where the problem lies.

Boot the stick using the one-time BIOS Boot menu key. Is there a choice for UEFI flash stick? If not then the stick is not formatted correctly or the BIOS settings are awry.

Boot into BIOS setup to report back all settings choices for UEFI, CSM, Legacy BIOS, BIOS Boot Priority order.

Confirm that the stick maintained the settings in Option One of UEFI Bootable USB Flash Drive - Create in Windows
after you added the ISO, since these can jump around then.
 
i noticed the settings jump when selecting an ISO in rufus, and i accounted for that.
As for the BIOS settings, i can only give you the boot order, as i cant find the other settings. (probably there, but i dont see them)
boot option priorities: (listed as named in BIOS)
1. P5: WDC WD5000AAKX-003CAO (my HDD)
2. P4: TSSTcorp CDDVDW SH-222BB (Optical drive)
3. Disabled

You have a UEFI BIOS but see no choices on any BIOS tab (usually Advanced, Boot and Security tabs) for UEFI, CSM, Compatiblity Module, Legacy BIOS? How about on Security tab for Secure Boot?

If the flash stick is plugged in at the time then it should show up in the boot order, and be listed as UEFI Flash stick providing it's formatted correctly and UEFI is enabled in BIOS setup.

Try plugging it in if not and check in BIOS Boot order AND one time BIOS Boot menu key.

If you want to install in UEFI, you have to create the EUFI usb installer, did you follow Greg`s tutorial and do that ?

The USB gets recognised in the BIOS and in the boot menu, but not as a UEFI device. Inside the BIOS there is no security tab, only Main, Ai Tweaker, Advanced, Monitor, Boot, Tool. I still cant find anything that matches your description

Addram: yes, i followed the instructions, set everything up as listed.

You should not disable UEFI install until it is first attempted correctly, as it offers the latest features of the BIOS. We once needed to disable UEFI because of persistent install problems, but these no longer prevail if there is cooperation in troubleshooting them.

Look at every setting on every tab of the BIOS for UEFI, CSM, Legacy BIOS and Secure Boot. If this is an EFI BIOS then there should be one of those. If not then the most rudimentary UEFI firmware only offers the UEFI choice when you insert a UEFI capable DVD or flash stick, and it needs to be chosen to install to UEFI. So make sure your ISO confirms using the HASH check in Step 1 of Clean Reinstall Windows 7 then write another stick making sure the settings don't slip from those pictured in Step 1 of UEFI Bootable USB Flash Drive - Create in Windows when you add the ISO. Do you now see a UEFI Flash stick choice when triggering the one-time BIOS Boot menu?

If this fails try DVD install. Burn ISO to DVD using ImgBurn at 4x speed.

So far, i managed to find one hidden UEFI/legacy option in the BIOS. Upon going to SATA configuration, setting the onChip SATA type to RAID, a new option appears: Board SATA RAID ROM. On that option i can choose UEFI DRIVER, Legacy ROM or Disabled.
Also found in the USB Configuration, the option for legacy usb, enabled or disabled. As well as legacy usb 3.0 support. Will look around more

I asked for all available choices. I would not change AHCI to RAID for SATA controller except to test if you can boot disk as UEFI to do install. If so then that RAID choice may be a generic SATA selection and not exclusively for creating a hardware RAID array. However I haven never seen access to UEFI in such a way, though its possible and worth testing for install if no other UEFI choices exist.

The other USB choices are standard in every BIOS. Enable both.
 
Those are all the options i found. Ive changed my settings back, and enabled the USB options.

I have an idea, weve been trying to solve the problem in the BIOS, if i understand correctly, which is on the motherboard. I could try hooking the HDD i want windows 7 on into a different motherboard, and try there.

*edit: dont have equipment for it, so nevermind

Confirm you're using a USB2 port.

If not try disabling USB3 in BIOS.

Can you get flash stick to show up as EFI with RAID setting and UEFI? When selected do other settings appear?
