I am quite new to Linux and Ubuntu. I recently ran into a pretty troublesome problem and was wondering if anybody could help.
At first, I wanted to dual-boot with Ubuntu 20.04 and Windows. However, I ran into a problem as I was trying to install it. I got this error message:
This computer uses Intel RST (Rapid Storage Technology). You need to turn off RST before installing Ubuntu. For instructions, open this page: help.ubuntu.com/rst
I tried following the first solution on this AskUbuntu post. However, when I booted to Windows, it immediately went into recovery mode. I switched the SATA controller and tried all of the recovery options, but it looked like my Windows was gone.
I have a Windows bootable CD, so I thought I'd just install Ubuntu over everything. I turned off RST and went to install it, but after installing it I realized that it only partitioned out 13.6 GB of my 1 TB disk. I had thought it would wipe the disk completely and install Ubuntu.
I tried installing it again but it only seemed to be able to sense those 13.6 GB. Does anybody know what happened and if I can fix it? Nothing I've tried seems to work. Thank you.
