I have a laptop with no CD rom nor Floppy Drive, but supports USB Pendrive boot (as well as PXE booting). I am simply trying to format the laptop's harddrive and make it bootable with just windows 98. Eventually I will install XP on it, using BartPE I will copy the installation files over network to a second partition on the hard drive, but meanwhile, all I want is to be able to boot from the harddrive, with Win98 dos prompt. I have successfully formatted the hard drive and made 2 partitions, both fat32. When booting from the win98 bootable pendrive I can see, and can access both partitions (D: and E:, since the pendrive is recognized as "C:\". From the usb pendrive I tried to make the D: drive bootable by typing "sys c: d:", but whenever I restart the computer, without the USB bootable pendrive, I get an "Operating system not found" error. Is there something else I need to do to make this hard drive bootable, other than making it a system disk, formatting fat32? Something to do with MBR? The tools I've used so far are: Partition Magic 8 (recovery disk), BartPE (from USB pendrive). Any help is appreciated! Edit: I did have a problem while running "sys c: d:" -- I got an error saying "Could not copy COMMAND.COM onto target disk", but I followed this MS Help&Support article http://support.microsoft.com/kb/96061, so I don't think that's the problem. Or is it?
