Computer won't boot

I am working on upgrading the hard drive to a 1.2G WD. The BIOS is 8/23/93 AMI 486DX-66. I used the CMOS disk utility to format the drive (mistake?)and auto-detect which appeared  to work OK.When I tryed to boot up the computer with the new hard drive installed it took several attempts before it read the DOS disk and started the install. The process then aborted and the message "NO ROM BASIC SYSTEM HALTED" appeared on the screen. I re-formatted the drive again and now when the system is booting it does one of two things. It gets right ot the point of "starting MS-DOS" and then automatically re-boots (in a sort of stuck loop) or it freezes.
    I've tried to put back the old drive and re-set the CMOS for it's parameters, but no luck in getting this computer to boot. I've set the CMOS from A:, C: to C:, A: boot sequence with no change in results.
     What am I missing??

You have to make sure that the PC supprts the large HD, some of the older PC's couldn't have a HD bigger than 540MB. Anyway assuming that the computer'ss bios detects the HD at 1.2GB. Leave the BIOS to a: c: get your DOS bootable disk in. If it's the disk 1 of the dos setup, it will go into the Setup screen. press F3 to get out of it. To do a low level format, you'll have to run the FDISK utility from the floopy disk, so type "a:\fdisk" this will bring up a menu, press 3 to delete the partition. Then press 1 to delete the primary partiton. Then follow the steps on the screen,  to make sure that you are deleting the right paartition it will ask you the volume name wich will be displayed on the screen. Then confirm the deletion of the partition. Then we need to recreate it. It should take you back to the main menu, this time press 1 to create partition, then 1 to create a primary partition. say yes to use the whole hd for the partition. Confirm the HD space and then give the partition a name, if you like you can leave blank, and confirm. Exit the program i think it will will tell you to press escape to exit. the copmuter will reboot, leave the disk in the drive and then you'll have to format it. So do the same as above press F3 to get out, then Type a:\format c: /s /u. Good luck. I hope this fixes your problem, if not comment and let me know how far you got.

mjvisser,
The proposed answer assumes that your BIOS supports the new drive.
I don't think it will.
You'll need some sort of "overlay" software (such as DiskManager) to enable your BIOS to make use of the drive's full capacity.
Let me know if you need more.
Regards,
Ralph
