I am trying to dual boot Pop! OS with Windows 10 on my PC, I have the disk partitions set up (about 50 GB for the new OS), as well as the .iso in a flash drive for booting. But whenever I boot from the USB to go and install Pop! OS, the new OS cannot see the hard drive, it can only see the USB that is being used to boot the OS.
In the help section of the installation process, there is a tip that fast startup needs to be turned off, which I then did, but after trying to install the OS again, it still will not detect the hard drive.
Any help would be much appreciated. I am using a Lenovo 81XH IdeaPad Flex. Thanks!
