Good news. Congrats.

Since your floppy doesn't contain a valid bootsector, it won't start from floppy here. At least my mkdosfs created boot sector says: This is not a bootable disk. Please insert a bootable floppy and press any key to try again ...
The simplest solution is choosing win(9*|me) from boot manager then, press F8 immediately, select boot to command prompt. (Hope this works in me, too) Issue c:\> sys a: and c:\> edit msdos.sys then, as above. If booting from floppy still fails, check BIOS boot order.
Note: if you don't trust your winloose inst., check the created bootsector: 1) Label at offset 3 should read MSWIN4.1 or the like 2) some readable error messages at around 0x180 3) IO SYSMSDOS SYS at ~0x1d8
BTW[FAR OT]: Somebody remember IHC here?
