This Samsung 250 GB solid state drive replaced my Seagate Barracuda 1TB 64MB Cache 7200 rpm 3.5-inch internal disk drive because I wanted to speed up my computers boot time. It is used to just store the operating system files. I have a Seagate Desktop SSHD 2TB 64MB Cache 7200 rpm 3.5-inch internal disk drive to store everything else. My computer now boots up very fast.

I also forgot to change the SATA controller mode from IDE to AHCI.

I had to open the RUN dialog box by right-clicking over the far left-bottom corner of desktop, selecting the Run option and then typing MSCONFIG and Enter.

Click on Boot tab, check the Safe boot box, and click OK to restart the computer.

After restart, go into BIOS settings by pressing Delete, change the hard disk mode to AHCI, save settings on exit and reboot. Windows will now boot in safe mode.

Run MSCONFIG again, go to Boot tab, uncheck the Safe boot option and click OK to restart.
