Got my laptop in February 2017 and it was working normally till about 3 months ago. Then whenever restarted, it enters bios and shows message "Hard drive - not installed".
If I continue, it normally just turns off and I have to start it again. Sometimes it starts straight away, sometimes I have to repeat this process a few times.
I tried a few solutions suggested for this error (from https://www.dell.com/community/Laptops-General/XPS-13-9360-freezes-and-shows-quot-Hard-Drive-not-ins...). SupportAssist doesn't show any problems, drivers are up to date.
Anyone experienced the same problem and if so, what did you do to fix it?
I have the same issue. Dual boot with Linux, weirdly it only says hard disk not installed on booting grub - windows boot manager works fine. Please solve this - this must be the third time a dell/windows update breaks my system.
