I have Acer VN7-791G-77GZ laptop and Crucial CT512M550SSD1 SSD drive. My laptop don't recognized disk drive on boot, but recognized it after reboot. Also laptop hangs after wake up from sleep.

So, how it happens:

  1. Laptop is turned off.
  2. I turn it on and it shows "Default Boot Device Missing or Boot Failed". No disk drives recognized by BIOS in boot section.
  3. If I simply reboot it, it won't recognize disk.
  4. If I boot it from Mint liveUSB it will booted.
  5. GParted from liveUSB can recognize drives. Drives are mountable.
  6. I reboot laptop. Now SSD drive recognizable by BIOS. BIOS can see GRUB and Windows Boot Manager.
  7. So after reboot i've boot Windows 10. Windows can work for dozen hours without problems, but laptop hangs if it goes to sleep.

  • Did you try updating your Bios? My own laptop will never recognize my SSD because it doesn't support it, got it working by putting a Windows Boot Manager on the secondary disk, which initializes first and sees my SSD, then the SSD takes over and continues the boot process

  • Unfortunately, Installation of latest BIOS (v1.11) doesn't solve my problem. Commented Mar 9, 2016 at 21:33

I totally erased all partitions. Now this disk is OK.
