|I have a pretty old (>4 yrs) Dell Dimension 4300 which worked fine till a few days ago. All of a sudden, with no changes made to the hardware or software, it regularly (in about 50% of the cases) didn't boot anymore. It shows the Dell logo and then it says "Primary drive not found." before it should show the Windows splash acreen. I then have the option of hitting F1 to continue, or F2 to go to a configuration utility. If I hit F1 it sometimes does boot, sometimes not. |
If I look in the BIOS (version A06, newest as far as I could find out) I usually see that primary drive 0 (and other drives too) is not configured (usually "OFF" or "Unknown Device"). If I set that back to "auto" (-detect) it sometimes reboots without any problems and sometimes it has exactly the same issue.
At one of the good boots I run an extensive chkdsk. No errors were found. I've deconnected and reconnected the IDE cables, no avail.
Anyone has any idea what might cause this?
