today my pc did not start, after the bios loaded, the message "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER' appeared. there are 3 HDDs plugged into the computer which are all shown in the bios. But if I boot from USB I can't select (find) any HDD.


There is no IDE device connected.

All HDDs are Sata

I am very sorry to bothered you but somehow magically after about the 30th restart it just started and showed some windows error which I was able to repair. Still not sure where this malfunction came from (since the corrupted hdd was not the active hdd)

Update: No it shows the error again

reseting bios made me able to acess the HDDs via Windows Installer. My previous windows installation was not detected. After formating C:\ and reinstalling now it seems to work.

Is there a floppy disk in the 3½ inch drive? (Or a unbootable pendrive/SD/whatever modern version of a floppy is on your PC). – Hennes Jan 16 '13 at 18:30
What version of Windows are you using? – techturtle Jan 16 '13 at 18:39
