Hello,
I have a Dell Optiplex 7170
Ram - 4GB
Processor - I3

I have Windows XP 32bit installed in it.The pc does not enter the Windwos when the SATA configuration in BIOS is set to AHCI (DEFAULT).

If i change the SATA configuration to ATA it will enter into Windows and work properly but if i shutdown and turn it on again the config changes to AHCI and doesn't enter into Windows.
