I Downloaded Wubi.exe & Ubuntu 12.04 LTS From The Official Website Then Put Them In A Single Folder In My Internal Hard Disk. Then I Run Wubi, And It Got Installed Within 2 Minutes. And Then I Rebooted My PC. Then Ubuntu Loaded Up And There Were No Icons Anywhere Just A Black Bar At The Top And The Ubuntu Default Background Wallpaper. Then A popup Came Up Saying Verifying Files And Then A Box Popped Up Saying "No Root File System Defined, Fix This In Partitioning Menu". I Tried To Close It But It Pops Up Again. And Im Stuck Here With Absolutely No Idea What To Do. Im Good At Windows But I Have Zero Experience Of Linux Ubuntu. I Need Help Desperately!
EDIT: I Tried "sudo parted -l" with lower case L. It Asked Me Whether It Was A GPT Table. I Said "No" Then Nothing Happened. But My Problem Still Isn't Solved.I Also Tried "sudo blkid" And It Told Me That My Hard Disk Partitions Are Of "NTFS" Type(Which I Already Know). Please Help Me.I Tried "sudo apt-get remove dmraid" But It Returned with a error code 1 And My Problem Wasn"t Solved.Installation & Un-installation Processes Take Less Than A Minute, Isn't It Fishy?
