With the PC powered off, remove the CMOS backup battery (CR2032) for AT LEAST 10 minutes (Intel says 15 min). Reinstall and then try. If it still will not boot I would suspect the BIOS was somehow corrupted.
There are many Inspiron 15 models. What is the exact model number?

Its the 15 7000 from about august 2016. I also can't find any guides online for getting the cmos battery out for this particular model.

There are reports that Ubuntu 17.10 corrupted the UEFI of certain models of Lenovo laptops.
The thread is in the Linux forum of the Lenovo forums.

FIXED: Remove CMOS battery, wait 10 minutes like fireberd said, put everything back together again, good as new
