I’ve noticed an issue on a few IBM/Lenovo Thinkpads. When you install an SSD drive, a reboot or restart from the OS does not work. When you reboot, instead 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:
- Shutdown the laptop then power on to boot.
- During the “Thinkpad” splash screen, Press F1 on your keyboard to enter the BIOS.
- Select Config > Serial ATA (SATA)
- Change the SATA Controller Mode Option from AHCI to Compatibility mode.
Reboot from OS should now work.
