I then tried to boot using the Dell operating sysem reinstall disk that came with the computer. I tried the repair install, and it reacted the same way as a normal boot as well.
I then found a second boot menu besides the safe mode menu, which had a few different options, including IDE Drive Diagnostics and Boot to Utility Partition. I ran the Drive Diagnostics, and the primary hard drive passed. Then I tried to boot to the Utility Partition, and got the same result as for a regular boot, with the flash of a blue screen.
I went back to safe mode and poked around a bit. I looked at MsConfig and under the Boot.ini file there was a button to check all boot paths. When I clicked it, I got a message saying:
It appears that the following line in Boot.ini file does not refer to a valid operating system
C:\cmdcons\bootsect.dat="Microsoft Windows Recovery Console"/Cmdcons
Would you like to remove it?
It had a Yes and a No button below that.
Is this the problem, and should I remove it? If not, what's my next step?
