Sometimes when the CMOS battery dies the BIOS will reset the drive configuration from AHCI to RAID. If that’s the case, you would not be able to see your hard drive until you swap the configuration back to AHCI. This is a common issue with Dell workstations. I actually just fixed two Dell Latitude laptops with this issue by replacing their CMOS batteries so can confirm it is very much still a problem (and has been since first experiencing the issue in 2012). When removing the CMOS battery the BIOS would reset back to RAID and the hard drive will be inaccessible. Not sure if that’s the issue you’re experiencing but definitely worth a shot. Edit: to clarify, make sure your BIOS drive configuration is set to AHCI not RAID. Answer from eggplant_zoo on reddit.com

Because you wiped the drive, all data including the Windows files were erased. You will have to reinstall Windows which you can do by downloading the media creation tool found here. That will create a bootable Windows installation flash drive. This support page explains the data wipe function. And this YouTube video should help as it is a good tutorial on a clean install of Windows 10.
