The hard disk is FAT32 format, a 2G IBM hard disk. An old Fujitsu laptop. The DOS installation CD is fine, because DOS can be installed normally on a desktop. But on the laptop it says no valid FAT32 partition can be found, and the installation can't continue. fuck!But my laptop really is currently using a stripped-down XP, in FAT32 format. Checking the hard disk under XP shows no problem at all! The laptop's hardware specs are low after all; although XP runs on it only barely, QQ, web browsing, and programming are all no problem. But one system takes up more than 800 MB, so there isn't much space left on the hard disk. But I have XP on my desktop, I just want to use DOS on the laptop.
