Learning all the Time
XP / Vista / Win 7 / Win 8 / Win 10
Hi Matt and welcome to FpcH
FreeDos is a DOS-based OS.
EFI is a type of FAT-based format - suitable for FreeDos but not Win7.
If you have Win7 you don't need it.
I would be tempted delete the partition ( using the Win7 disk ) and format the whole disk as one partition.
If you wish you can create a second partition later from DiskManagement. ( I am not a Win7 user and I am assuming that it is similar to Vista in this respect ).
