Operating System Not Found

By TWonk ·
Hi. I was given a PC without a hard drive. So I installed onto the Gateway PIII-550 Mhz/128 MB RAM PC a 40 GB Western Digital hard drive and W2K Pro operating system. The disc was partitioned and formatted to 8 and 32 MB on drives C and E, respectively; W2K Pro is on drive C, CD-ROM on drive D. Setup was ok.
After POST-ing from a cold boot, though, it stops with a flag ?Operating System Not Found?. A few warm boots gives the same flag. Only after entering the BIOS and doing essentially nothing but exiting and rebooting does it proceed into W2K Pro O.S., sometimes. The Boot-up files were copied off of this retail version of W2K Pro O.S. onto floppies and loaded from a cold boot. It booted ok the first time and proceeded to W2K Pro, but upon shut down and a cold boot, the flag returns. It only precedes to W2K Pro after alternating warm and cold boot a few times, plus entering/exiting the BIOS with no changes.
Note- the appropriate Phoenix P14 BIOS flash for the Tabor motherboard was downloaded to floppy for an update. But, even though the floppy was moved to the first bootable object in the BIOS, the warm reboot from Windows GUI failed to produce the Intel Flash Memory Update Utility dialogue box to allow loading of the update program. The warm boot then proceeded past the POST back to W2K Pro GUI.
So, any solutions for fixing a system that boots improperly to its Windows destination?
Thank you for your reply, TWonk.

Was the HD that you installed pre-installed with the operatin system? If so, the HAL will be different and will not work. I would suggest reformatting the HD and re-installing the operating system from the CD (booting from CD). If the operating system is not found, it could also be a bad connection on the HD, please make sure that all connections and jumpers are set correctly on the HD.

You must verify for the first time your HDD. The first partition C: (8 MB??? I spouse is 8 GB) is active? You can verify this with fdisk. The other possible think is how jumper is your HDD. Even with installed OS on other computer it must boot on new computer, and you can install the specific drivers for your new hardware.

sounds like hdd controller or jumpring on the drive. you really need to get that bios updated.
can you get hands on older promise ide controller like ultra33 or ultra66.
but the boot when BIOS properly identiies the drive sounds like maybe you need to have the wd configured as 'sole drive' (no jumpers). or you need to have it configured backward compatible mode or something. i would research this on the gateway website. what cable you using? what model exactly is the drive.
what can you configure in bios regarding the drive. can you sloww detection. can you enable lba. have you played with all of that.
i bet if you find an older 4gb drive and stick that in you will work fine

Another possibility is that the M'Board can not recognize that size HDD. Some of the older P3 M'Boards had an upper limit on the size of the HDD that they could recognize.

While Flashing the BIOS may cure this problem if you do not have the most up to date BIOS you may need to alter the size of the HDD to a jumpered 32 GIG max. I'm not sure if WD have this option but Seagate certainly do and you can jumper a 40 GIG drive to 32 GIG which should be recognized by the M'Board. While I know it sounds as if you are wasting money by having 8 GIG that you are not using buying a suitable HDD is far more expensive than just jumpering down a bigger drive.

You'll need to go the Gateway Site and look for BIOS Updates for your model and see what they give you as an advantage of installing them.

The W2K Pro OS was installed from a CD to drive C, partitioned to 8GB only. The 2nd partition is
32GB with nothing on it. The times I was able to proceed to Windows,Windows Explorer showed the drives to be 8 and 32 GB, respectively. So, BIOS
is able to see all the whole 40GB drive, it just
won't boot properly.

To flash the BIOS, you could disconnect the HD and force it to look for another OS (aka A drive). The flash should update the BIOS to allow larger than a 6 GIG primary partition (PIII - 550Mhz, if memory serves me correctly).

Or you could repartion the HD to 6 GIG primary and 34 GIG extended.

Try this. Take a win98 boot floppy.

Don't have any other hard drives on the system.

Boot the system and at the a: prompt type the following.

fdisk /mbr

and press enter.

This will replace the master boot record.

Remove the floppy and reboot.
