I have a Dell Latitude E5450 with a 128GB mSATA drive, which has been working fine for 3 months. I have the latest firmware for the BIOS (A10). I have Fedora 22 installed on this disk and have had no issues until this week.
When booting I get a message "No boot device found". I had a look in Diagnostics and it tells me it couldn't find any hard disks. I looked in the BIOS and it also doesn't show any disks. Hitting F12 for the boot menu shows no internal hard disk.
If I boot a Linux live CD (Fedora, or any other recovery CD), run "fdisk -l" I can see /dev/sda (the drive the BIOS can't find!). Now if I reboot, the disk is detected and the OS on the disk boots just fine.
If I reboot again, it works fine. If I power down the laptop, the problem starts again.
I'm not looking for the following answers because the disk boots once detected, these options are not answers to this question:
- suggest changing the boot order
- suggest changing the AHCI/IDE option (it's not an option on this laptop)
- suggest changing the SATA operation option (AHCI or RAID)
