i get the error message “Boot disk failure, insert system disk and press enter.” when switching my computer on. it was fine about 2 hours ago but now this is happening. I checked in my bios to see if the disks were being recognized and they weren’t. I panicked for a moment and then thought about obeying the error message so i put in the system disk and got to the recovery console, only to find that i could log onto my two XP installations and browse the directory structures just fine. so the windows setup application has obviously recognized my two SATA hard drives, but my stupid BIOS won’t. Can anybody suggest a cause, solution or workaround for this problem? it would be most appreciated.
