Windows 7: Setup was unable to create a new system partition

Setup was unable to create a new system partition

Hi folks!

I've been experiencing some troubles installing Windows 7 from a bootable USB.
I was so clever that I deleted all the partitions even with my Windows 8.

I was trying to downgrade and had loads of issues getting the USB to work, but that's fine now and I got to the setup. However, I had problems with partitions unable to be written onto. I have cleaned and formatted and set the partition to ntsf as I found somewhere in these forums. At The end, I'm still getting the same old error setup was unable to create a new system partition..............

Any help would be greatly appreciated

Hmmm, is this a UEFI based system? If so you need to do things differently to install Windows 7.
See here: UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with

If no help, try this.

Delete both partitions.
Create one single partition encompasing the entire drive (you can re-size it later if you want another partition or two).
DO NOT format, just click next and let the install program do what it needs.
See if that works.

If that is an UEFI system you may have to set the BIOS to Legacy Mode.

Your specs say LENOVO.

1) DISABLE Secure Boot.

2) Boot the Windows 7 x64 DVD in UEFI mode.
3) Delete all partitions & than use Drive Options>NEW to make the UEFI Partitions.
4) screenshots in

Thanks guys...worked like a charm! For some reason I considered that first partition to be my USB (just cause of the similar size - although....I have no idea why - was scared comp. recognised it somehow)

It's all well now. I'm all set. Thanks for The help again
