Hi I have a Dell 8400. I am trying to reload the OS MS XP Pro. Unfortunately the setup does not recognize any onboard HDD's It will recognize all the externals but. not any of the internals. I can see the HDD's under Disk Management By all appearances it all seems normal. The PC is up and running and C: & D: are visable for usage with out issue. The problem is the PC is doing some hinky stuff. Some folders I can not delete they are empty etc. Everything has become painfully slow despite the fact the PC has been cleaned and defragged. This is driving me crazy though I do not have far to go.
Thanks

this helped when i was trying to install a new hd on a friends dell...
Reboot your system and hit F2 as soon as you see the Dell startup screen (the options are F2 for setup, F12 for boot sequence).
In the System Setup screen, do these steps.
Select Drives:
Make sure your Diskette Drive (3.5 floppy) is set properly (Usually set to Internal)
Make sure that "Drive 0: SATA-0" drive is set to "ON"
Go to "SATA Operation":
Your system proabaly came set to "RAID Autodetect / AHCI" - THIS SETTING CAUSES YOUR SYSTEM TO GO INTO AN IDE LOOP AND DOESN'T ALLOW IT TO FIND YOUR FACTORY INSTALLED SATA DRIVE.
CHANGE THE SATA OPERATION SETTING TO "COMBINATION"
Reboot - make sure that the boot sequence is set to CD rom before HD and make sure that the reinstall CD is in the drive. Setup will load, hit enter to reinstall XP PRO. Your HD should now be detected and you should see the licensing agreement.
If you have your files backed up I recommend deleting the partition and reformatting prior to installing XP, it will give you that option after the license agreement.
Once you have successfully reinstalled the OS, Dell recommends that you change the SATA Operation setting back to RAID AUTODETECT / AHCI (or back to whatever your factory setting was) to avoid any problems with other IDE devices installed on your system.
Hope that helps!
