If the partitions have been deleted, it has no bootable OS..the hard drive will need to be re set up and formatted, Windows will have to be re loaded.
He was doing it correctly because the OS was paid for by someone else, and is not transferable unless the setup CD comes with the deal.
You will need a diskette with fdisk and format on it..you can get one by going to
www.bootdisk.com and downloading the Windows 98 Se boot disk (can't remember the actual version..if needed, I will get the info for you...only a couple of those boot diskettes have fdisk and format, etc included.
Then, hopefully you have a CD drive and a legal copy of an OS to reinstall.
