"Operating system not found"

by Wayne Lockwood / April 2, 2007 3:21 AM PDT


I have a Dell Inspiron 1100 that froze up. After turning it off the following message came up: "Operating system not found"

In my atempt to boot from D: , I used a system disk to reinstall the system that came with the computer new. A hardware diagnostics test came up & suggested a fan test failure. After a help website, new thermal compound, a cleaning of the fan I have hopefully overcome hump #1.

C:\> DIR
1 FILE 93,880
0 DIRS 33,439,744

SCANDISK: "no problems"


33,538,000 bytes total disk space
98,304 bytes in 1 user file
33,439,744 bytes available on disk

16,384 bytes in each alllocation unit
2,047 total allocationn unit on disk
2,041 available allocation units on disk

655,360 total bytes memory
547,632 bytes free

** I did try to copy the i386 off a reinstall disk; however, ran out of disk space & could not acces a dir to remove any files.

Any suggestions are greatly appreciated--THANKS

Not sure I understand

If the red message above each posting page is missing please let us know so we can tell the techs.

I'm not sure I understand here. You say you were attempting to boot from D? What is your system configuration?

You fixed the fan, cleaned out all the dust. What happened then when you tried to reinstall the XP? What error messages did you see?

Using the XP CD, did you try and re-format and re-install of the whole system?

The reason the operating system is missing is

because it is not visible. Make a Partition Magic Boot Magic rescue floppy and boot from it and it will show the operating system as hidden. Select it and boot and Windows XP will boot up for you.
