Hello everybody,
I have a Philips NMS TC-100 with 8088 processor. The defective MFM hard drive has been replaced with another MFM hard drive. In this new hard drive there was a French version of DOS.
I wanted to replace the operating system with an English version, and then I deleted the primary partition with fdisk.
On reboot, I get the error "missing operating system" and it doesn't boot from the floppy.
If I detach the hard disk, the computer correctly boots from the floppy disk. But of course I can't install the new operating system on the hard drive.
The BIOS menu cannot be accessed on this computer. The settings can be changed through the dip-switches on the motherboard. But on the original computer manual, there is no way to change the boot sequence. There is no switch that allows you to change the boot sequence.
Is there a way to force boot from the floppy disk without detaching the hard disk? Otherwise I can't install the operating system!
Thank you!
