I'm new to Linux and faced a problem which is really serious for me.
I downloaded Ubuntu 12.04 ISO file and used Unetbootin to make a usb stick. I had installed Windows 8 that moment, unfortunately I couldn't install Ubuntu alongside Win8 so I erased my disk and installed Windows 7. Sadly I can't have "installing Ubuntu alongside with windows " option now too. I tried other version of Linux or even Ubuntu 13.04, but still the answer was NO.
I have: Asus K55v 6G RAm, 750G HDD, core i7.
My disk is MBR with:
1)100 Mb System reserve 2)C:126G primary 3)D:244G Logical 4)E:284G Logical 5)43G Unallocated
I can't install Ubuntu manually because it can't see my partitions or Unallocated space,it just sees my whole hard disk entirely, I tried it and it erased whole of my hard disk.
I don't want to use Wubi. BTW all that I was talking Here was about _64 bit OSes. Few month ago I had no problem of installing win7 and Ubuntu alongside!
I'm getting worry about maybe my laptop has physical or some kind of problem.
