Changed Sata settings in BIOS now disk is invalid
My laptop wasn't running games as it should so instead of troubleshooting the problems we decided to do a clean install of windows 7. None of the drives would show up so we looked it up and used the driver cd that came with the laptop and they weren't on the disk. then we tried to boot from the OS to find the drives. We were able to find the drives but couldn't format them or delete any. We read through the options and it said files would be moved to windows old and we wouldnt be able to boot from it and we would be able to delete the partitions later. Windows wouldn't reboot after the installation and i had to choose which windows 7 to boot from so i restored the original to factory and tried again and it still didn't work. now there's a windows setup option and two windows 7 options during the boot screen. We did more research and we found out we had to change the sata settings in the bios to find the drives. I changed from the default intel settings to AHCI and booted from the cd. We were able to find the drives but couldnt delete any of the partitions. instead of formatting the disk and reinstalling they reinstalled again on the current copy of windows now theres three windows 7 options and one windows setup option and all of them go to blue screen. i tried to do it again but theres just an unallocated space disk that's about 100 gb. the 500 gb disk drive can't be found. while booting from the cd i ran diskpart and it says disk 0 is invalid. the computer had a RAID setup and i think changing the options in the BIOS is why. we've tried changing it back and no luck. would clearing the drive with diskpart and doing a clean install fix it? if not can someone please explain how to fix what's happened to this computer
