I'm not sure if this should be posted here or under hardware. Anyways, my sister has a Compaq Presario C501NR notebook with Vista Home Basic. RECENTLY it has stopped booting. At first it gave me an error that the file ntdll.dll was corrupt. I tried using the HP Recovery Manager, but was unsuccessful. I then ordered the recovery disc from HP. After receiving the disk I put the disk in the DRIVE and it booted up to the HP Recovery Manager. It reformatted the hard drive, created a partition for a recovery image and then installed the image on the drive. It said to restart the computer and then press F11 to complete the process. This is where I run into problems. Pressing F11 doesn't do anything except beep. As it attempts to boot it gives me the error 0xc00000e9 stating that there is a problem COMMUNICATING with a device. In the BIOS I ran a test on the hard drive. After about 15 seconds it says "#1 - 07 Fail." I have tried everything I know, but as I am a programmer and don't deal with hardware that much, I don't know what to do next. Any help would be great.Sounds like the harddrive has failed. Before running out and purchasing a new one, however, try this first:

Unplug anything connected to the computer. This includes any mice, printers, game controllers, PCMCIA cards, anything "extra," to see if something's causing problems.Yeah...error "0xc00000e9" indicates some problem with loading a driver, so "Anodoin" suggestion may help.I disconnected everything from the computer and that did nothing to help. This is rather annoying since my sister hasn't even had this computer for a full YEAR yet. I guess I'll just have to get a new drive.The BIOS test is not that extensive...travel to the drive maker's site and DLoad their free diagnostics and run it...
