I've got Toshiba Satellite U50t-A-10H with Win8.1 installed, UEFI, HDD 750GB + 32GB SSD cache.

I'm trying to install Ubuntu on it. I've split my disk, made 200GB free unallocated space and booted Ubuntu USB. I proceeded with settings to install Ubuntu and I've got to stop on the partition manager page where I needed to choose disk where it should be installed. Nothing was there. No drives, just blank window. When I clicked on some button or on Install button the whole installation window freezed.

Ubuntu partition manager in liveUSB Ubuntu alerts that there is something wrong with drives and wants to fix or ignore the problem. When I ignore it, it starts normally and sees the whole 750GB disk as one drive with ! next to it.

Switching from UEFI to CMS mode doesn't help, same problem.

First I wanted to do dual boot but I'm OK with formating the whole disk and installing only Ubuntu. How could I do it? Does anybody know what the problem could be?

EDIT: output sudo fdisk -l (if it helps):

We can't see the disk in ubuntu at any version because all disk is has allocated ubuntu. If we want to see whole disk space then go to system setting and its show all configuration of computer as well.

  • But how can I install Ubuntu when it doesn't see disk? – Jakub Turcovsky Jan 24 '15 at 13:48
  • While you installing ubuntu from your system its asked how much you want to give space him so by default give him 100GB. And then follow instructions one by one. – Verma Jun 20 '16 at 06:48
