Win7 install, setup was unable to create a new sys partiton...

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

My drive setup is as follows:

Drive 0 200gb, trying to install win 7 on this one. This was installed into the computer recently.

Drive 1 Total 250GB. Has ubuntu installed
Partition 1 Primary: 140gb, ext3
Partition 2 Logical, 91gb ext3
Partition 3 logical 3.9GB, swap

Both drives are sata, Drive 0 is first to boot from i believe. Anyway, i had an 80gb drive originally that failed, when i removed that I rebuilt grub on ubuntu to just recognize ubuntu and its own drive (drive 1). Thereafter I stuck Drive 0 in, and tried to install Win7 on it, and got the above error. I disconnected my ubuntu drive, and the error is still present. Heading home from work now, but pile on the suggestions. Ill try them tomorrow.

 

We couldn't create a new partition or locate an existing one.

So I was doing a clean install of windows 10 using a USB and I deleted all the partitions including the system reserve one. The only drive left now is "Drive 0 Partition 1". It is set as primary.

The problem is everything I click to continue the installation, I get the error "We couldn't create a new partition or locate an existing one."

I followed instructions from sites such as this, Error: 'We couldn't create a new partition or locate an existing one. For more information, see the Setup log files.' when you try to install Windows 8 (CP)
and I still got the same error.

I would greatly appreciate it if anyone could help.

 

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that
