Compaq Armada Laptop won't boot - Help!

[Fatboy]

I bought a 2nd hand compaq armada M300 laptop a while ago - I've got an external floppy drive, but no CDRom.
I put the harddrive in my desktop, partitioned the hard drive, then put the win98 CD on the D: partition, put the hard drive back in the laptop, and booted up off the floppy drive. I then ran the windows 98 setup off the d: partition.

The installation went fine, but when it got the the 'reboot the computer' step, it wouldn't boot, and I get the error message:

'Invalid system disk - Replace the disk, and then press any key'

But If I put the drive in my desktop, it boots up fine?

Anyone got any ideas what this could be?

Cheers,

Grant

Ah, cheers for that ernest - I didn't format s the C drive - I assumed windows did that when it set up - I'll give it a try.
