Dell 755 SFF won't boot properly
Hey Guys!
I got a old Dell 755 SFF.
The computer isn't booting "right". On every start it wont find boot devices.
But with a press on F12 during boot i can boot from a USB or HDD.
So i pressed F12, installed Windows 7, rebooted and.. yep! nothing.. No boot device found..
USB and HDD are properly recognized by BIOS...
Boot device order in BIOS is: HDD, USB, CD/DVD
May you help me?

Are you sure the boot HDD is connected to SATA 0 on the motherboard?

Look in BIOS setup for the option to disable USB boot support, save the change and exit.
See if that helps.

Reboot, press F2 and open BIOS setup. Look for SATA Operation option. Is it set to AHCI or ATA?
When was last time motherboard battery was replaced? Probably a 3-volt CR2032 lithium ion battery, ~$2 at discount stores.
