Setup was unable to create a new system partition

Hello,
i am trying to install windows 7 on my disk and when i click install i get this message:
Setup was unable to create a new system partition
See log for more information
I followed this guide: Setup was unable to create a new system partition: Fix for Windows and now it says in installation window that partition is system and it still doesn't work.
In ease us partition manager it says it is: Primary and active as it should be, so i don't know why it is doesn't let me install Windows.
Thank you for answer.

Simple way is to delete all partitions and leave drive blank so it's like a brand new drive

I have one partition on disk i want to install windows for data and second i made for windows, so i can't delete all partitions on disk, if that's what you meant. Or i could move it to another disk i have enough space, if deleting all partitions on the drive and making new would help. I had already installed windows there and it got corrupted, so i needed to reinstall. No idea why it doesn't let me install now.

You must give us more details.
- Are you trying to install booting from a DVD or flash drive? Is it a OEM reinstall disk or a normal M$ win 7 installation disk?
- Is G: cleaned (no data on it)?

I am trying to install from booting usb, downloaded Windows 7 ultimate SP1 x64 from official site.
Yep it is clean, i made manually that partition with diskpart and it is primary and active so it doesn't make sense it still doesn't work, because after googling this issue, it found articles, saying it doesn't let you install, because you are trying to install onto logical partition.

Open disk manger (C:\Windows\System32\diskmgmt.msc) delete the G: partition. You will have than a 42.8G unallocated partition. Click on it and create a new primary NTFS partition.

You can also do it under Win 7 install. Boot the win 7 installation disk, go to install, advanced - select the G: partition - delete it and choose to install on the unallocated partition.
