I was having Intel Rapid Storage Technology RST issues with a newly installed drive...did not need performance so switched BIOS to RAID auto/ ATA to eliminate the Intel RAID controller usage
- Run msconfig (right click far left bottom corner of desktop then left click run, type msconfig).
- Click boot tab, mark safe boot, restart, change to AHCI in BIOS, boot, Windows boots in safe mode.
- Run msconfig again, boot tab unmark safe boot, restart PC.
