I was trying to set up dual boot on my laptop which came with Windows 10 pre-installed. I wanted Ubuntu 18.04 alongside windows, but while setting up Ubuntu, I noticed that I need to disable RAID for the hard disk in order to view the hard disk partitions in Ubuntu installation process.
So, I went into the BIOS and disabled RAID for the hard drive on my laptop. However, now, I don't need Ubuntu, and I am trying to enable RAID back on for the Harddrive, but I don't see an enable option. A few of the online resources said that I need to access the Advanced tab of the BIOS to be able to do this, but my BIOS doesn't have an advanced tab.
