I need help installing Ubuntu on my Dell Inspiron 7577.
Note, this laptop comes with windows 10 pre-installed on a SSD.
I tried installing Ubuntu 17.10 using a USB device. But as I went on with the installation it said that it didn't recognize any operating systems on my computer. It also said that I was force booting into UEFI mode and it would cause problems with the dual-boot also.
I researched and found that if I switched from RAID to AHCI the Ubuntu installation would finally recognize windows and give me the option to install alongside it.
Now the problem is, if I switch to AHCI then I cannot boot into Windows anymore.
How do I solve this? please.
I ran this: export LC_MESSAGES=POSIX; sudo lsblk -f; sudo lshw -C storage
