|If you're asking about creating a dual boot setup, you'll have to start from scratch. Your hard drive will need at least 2 partitions - one for ME, one for XP. The ME partition MUST be FAT32, the XP partition can be either FAT32 or NTFS. However, if you want ME to be able to read the XP partition, both partitions must be FAT32. This is were it gets a bit tricky. The Microsoft formatting tool limits FAT32 partition size to a max of 32GB, so if you want a larger FAT32 partition than that for XP, you'll need to use a 3rd party formatting tool. The HDD manufacturer has software that can be used for that - it's available at their website.|
Once you get the partitioning straighted out, install ME on the C: partition. Once that's done, boot onto ME, then pop in the XP disc. A Window will pop up asking you if you want to "upgrade (recommended)" - do NOT do it! Instead, click on "Advanced" & direct XP to install to the D: partition. The installation will proceed as normal from there & the dual boot menu will be created automatically.
