I bought GA-MA770 yesterday, aswell as Phenom X2 II 550 BE.
Anyway, as i finished connecting everything i turned on the computer.
After a few secs bios loaded and a big message appeared
""DISK BOOT FAILURE. INSERT SYSTEM DISK AND PRESS ENTER""
So i started googling.
I've found something what appeared to be a solution. I connected my DVD drive to 4/5 sata port, then loaded failsafe configuration, then optimal and then save.
But it didn't help.
Here's what i have done so far :
i v bought new sata cables
i checked the voltages, both my hard disk and dvd are getting enough of it
i tried to boot dvd only, then hd only, then both
i tried bios reset, didn't help
i've tried switching to AHCPI, didn't help
i connected the hdd and dvd on the second machine, the devices work
Does anyone have any idea what to do? Here's my setup
Assuming your HDD and optical are both SATAs, connect HDD to SATA2_0, optical to SATA2_1; enter BIOS, go to "Integrated Peripherals" page; make sure "Onboard LAN Boot ROM" is disabled, set "OnChip SATA Controller" to "Enabled", "OnChip SATA Type" to "Native IDE"; go to "Advanced BIOS Features" page, set "First Boot Device" to "CDROM", "Second Boot Device" to "Hard Disk", check that the correct drive is first in "Hard Disk Boot Priority"; <F10> to save and exit; reboot with OS install disk in DVDROM - you will need to reinstall the OS for a new motherboard...
