I'm installing windows 7 onto my computer after upgrading my CPU and what not.
My computer's about 8 months *young*.
My harddrive and everything worked before I moved parts around, and now when I'm reinstalling windows 7, it gets to where it says: Where do you want to install Windows 7?
Then it doesn't detect my hard drive..

I;ve tried many different and working cable/power next tothe SATA cable for my harddrive. I also tried using a different WORKING sata cable. I also tried a different WORKING sata slot on my motherboard.

On BIOS Settings -
Under Advanced:
Storage Configuration
Onboard SATA Controller: Enabled
SATA Operation Mode: IDE
SATA IDE Combined Mode: Enabled

IDE1 MAster: Not detected
IDE2 Slave: Not detected
SATAII_1: ATAPI CDROM
SATAII_2: Not detected ...etc.

I already tried resetting CMOS, etc. ._.

:(

You should still be able to get to the command prompt from a USB installer if it was properly created, you do not need to go into the bios first other than to start from the USB. I usually use the MS Tool from HERE.

I generally put my boot drive on the lowest # (0 or 1) then HDDs, and then optical -- of course for an install on an SSD I leave HDDs disconnected until done.

What motherboard? What SATA port are you using for the HDD? A SATA II or SATA III? Not on a Marvell or AS_Media port?

I would see if the drive shows up in diskpart. To do that boot from the Windows installer disk but don't try to install, just go to the command prompt and type:

diskpart
list disk
select disk n (where n is the disk we are looking for from the list disk)
clean

If it shows up and cleans, then it will be a single unallocated partition where you can install Windows 7.

Are SATA Ports supposed to matter? o_O I tried plugging it into I and II, but I haven't tried the rest ... it goes up to six ports. I never had to use the other ones because my hard drive used to work before ._.
I'm booting from a USB - how can I go to the command prompt from there? Do I go to the BIOS first or...

Try disabling Sata IDE Combined mode (it means different things on diffferent motherbds)
Set Sata mode to ahci
Hard drive on the lowest number AMD sata port. Cd/dvd drive on the highest numbered AMD sata port.

Edit - for specific help we really need your motherbd model# and the drive you are using.
