Ubuntu doesn't show any Partitions avaible

[DonMacorli]

Hello everyone, I am having a problem installing ubuntu. I tried back in January but fail because of the same error...

So I have a hp ultrabook laptop. It came with 4 primary partitions: Recovery, HP_TOOLS, System and C. After searching a little I decided to delete HP_TOOLs and reduce my Windows partition(So i have around 10Gb free). Problem is that whenever I try to install ubuntu it doesn't show anything :/

Does any one now what could I do? Note that after installing ubuntu, i'm planning to reinstall windows since I've had problems with it since last time i tried to install ubuntu(it doesn't reconigze new usb anymore for example)

This is what my computer shows when i type sudo parted -l:

Model: ATA Hitachi HTS72323 (scsi)
Disk /dev/sda: 320GB
Sector size (logical/physical): 512B/512B

The last one is my usb where i currently have the ubuntu iso.

Thanks in advance for any help

If you are planning to reinstall windows you need to do this first before installing Ubuntu because if you do it will over write the MBR. It is better to do the windows first. When you reinstall windows do a format.

Did you create another NTFS partition? You still show 4 primary partitions and with MBR(msdos) that is the limit.

My laptop already has 4 primary partitions: how can I install Ubuntu?

Good advice on how to handle all four primary partitions used. - srs5694

Be sure to create recovery DVD(s) first. And a Windows repair CD.
