Loading an O/S depends on the one used.
For Windows NT-based O/S (Win 2000, XP) the process is:

> Load Master Boot Record from boot device (1st sector of disk) (contains program code and partition table (one partition set "active")
> MBR identifies boot partition and loads program code from boot sector (1st sector) >
Load and run NTLDR (expected in root) - ascertians file system (NTFS / FAT); reads boot.ini (expected in root) to present Boot Menu
> Run NTdetect.com (identifies hardware) >
NTLDR loads operating system core (NToskrnl.exe etc. (from system32)
> NToskrnl.exe loads remaining operating system files
