2100 HDD0 Initialization Error 1

I’ve seen a problem on some IBM/Lenovo Thinkpads. When you install an SSD drive, rebooting or restarting from the OS does not work. When you reboot, instead of opening the boot partition, it throws this error:

2100 HDD0 Initialization Error 1

Other than avoiding reboot and using shutdown instead, the only solution I’ve found is this:

  1. Shut down the laptop then power on to boot.
  2. During the “ThinkPad” splash screen, press F1 on your keyboard to enter the BIOS.
  3. choosing config , Serial ATA (SATA)
  4. Change the SATA controller mode option to AHCI To compatibility way.
  5. reboot

Reboot from OS should now work.
