Compaq Presario Missing Boot Partition

Hi there everybody! Was hoping some one could point me in the right direction. One of my co-workers has a Compaq Presario 7360 (500 processor, 64K ram) that spit out the following message when she turned it on a couple of days ago:

No Operating System Found.

She brought it up because she was thought maybe one of her kids clicked or unchecked some option they shouldn't have. :D I explained that it is pretty difficult to remove the o/s by "accident," and told her to bring it in.

She didn't have anything on the HD that she was worried about recovering, so I started by throwing in a Win 2K disk and booting the pc: No o/s detected.

Thought maybe the hd was fried and somehow interfering with the cdrom, so I opened the case and disconnected the hd. System boots to the Compaq start-up screen, checks the ram, then says "Press any key to boot from cd". I hit the keyboard, Windows 2K loads and ultimately says there's no hard drive and it can't install itself.

Installed a spare hard drive I had, reconnected everything, tried again.

This time the system tells me that there's a disk controller error, but then Win 2K starts, detects the hard drive, asks if I want to install on existing partition or format, formats the hard drive... then says Windows 2K has to reboot and setup will resume on startup - except that instead of "resuming" the whole thing restarts... disk controller error, Win 2K kicking in, detecting the now formatted harddrive, asking if I want to install on existing partition...

Etc.

Did a bunch of research online and discovered that Compaq stores some of it's BIOS info on the hdd... and that I am supposed to be able to download a couple of files off the Compaq site, install them via A: and zooommm - off I go...

Except I can't find the damn files anywhere...

Anyone have any suggestions? Is the BIOS even the problem... ?

Thank you, thank you, thank you, for even reading this far! :D

Some of the diagnostics and BIOS manipulation stuff are put on a non-bootable partition at the front. You download 2 floppies from Compaq, 1 of diagnostics and 1 of diagnostic partition management. After loading you then access the partition with [F10] when the cursor blinks in the upper right of the screen during POST. And it is possible to build one of the systems without the partition.

Fdisk and delete partition would do the wipeout. But I would suspect controller problem based on the additional problems you have.

Kaeri,

I am having the exact same problem. Co-worker just brought me a Compaq 7360 with the same symptoms. Compaq does store part of the BIOS on the hard drive in a hidden partition. This process is known as Initial Microcode Load (IML). I located the ROM BIOS update from Compaq at the following URL but before you try it be forewarned... After updating the BIOS successfully the system would only boot to the Compaq flash screen. I cleared CMOS with the jumper and also removed / replaced the system battery and now the system boots, checks memory, then hangs on the splash screen. Before updating the BIOS I was able to enter the BIOS setup (F10) but now the system says that it is entering setup but never goes any further. Also the system will not boot to either the CD-ROM or Floppy drive which it did before updating the BIOS. Sigh... hanging it up for tonight as I have to get up early for work. If you have found any info from another source please share. Thanks!

Problem solved. Hard drive failure (Quantum Fireball) had a burnt chip on the hard drive logic board. Replaced drive with a new 7200 RPM Maxtor unit and a clean install of Windows. System up and running fine.
