Why does Ubuntu 13.10 not detect my Win7 partition?
- by goutham
I'm trying to install Ubuntu 13.10 alongside Windows 7 on my DELL INSPIRON 14z 5423 laptop and I'm new to all of this.
I'm using the Ubuntu 13.10 64-bit ISO burned onto a CD.
The first time I tried to install it, Ubuntu said it did not detect any other OS, which meant I only had 4 options:
Erase disk and install Ubuntu (I don't want to do this)
Encrypt new Ubuntu.
Use LVM.
Something else.
If I choose the Something else option, it brings me to the partition menu and says that I have 1 disk with free space of (500Gb), but that's not true because I have Windows 7.
I restarted the laptop several times and booted the CD again and I got exactly the same as I did previously.
How do fix this problem and install Ubuntu alongside Windows 7?
After executing "sudo fdisk -l" command in terminal
