Either your setup floppy boot failed or setup script on floppy is unable to
handle partition scheme on disk.

I think you need to check BIOS settings first to see if you are really
booting from floppy and if you have disabled virus checking.  Eventually, if
it is proprietary designed machine with enhanced security,  check if there
is not any other lock enabled on disk system sectors.

Banks are often using expensive machines with proprietary design and some of
them (like Compaq or  Dell machines) are requiring small service partition
on begin of disk. So be careful with utilities like delpart.exe (you can
download this one on MS web site). First use fdisk and check partition
scheme, if there is small (20-40MB) unactive primary partition of unknown or
weird named type (ie. not FAT, big DOS, NTFS or HPFS) on begin of disk, do
not delete it and do not use delpart.exe on this machine. Use fdisk or
similar partitioning tool and delete remaining partitions, create one
primary type FAT32 partition, set it active and try to run your floppy
again.

Note that if you have problem with deleting NTFS logical disks using FDISK
and you cannot use delpart to clear out whole table, you can use any NT
based OS installation CD (or even only NT setup floppies - look for images
on www.bootdisk.com if you have not any) and run installation until
partition setup screen, delete unneeded NTFS logical disks from here and
cancel installation immediately.
