Dual install Win 7 and XP

I am running W7 64 and need an XP dual boot machine (Logitech doesn't support their old wheels in W 7 64). After reading the tutorial I started by creating a new partition and renamed to S: the 100 Mb W7 system partition. Now in W 7 I can see the following:
C: W 7 partition
D: DVD/CD
E: Win 7 data partition
F: New partition for XP
S: System partition.

Insert the XP disc and when prompt to select the partition where to install XP the drive letters are mixed up. The partition I want to install XP appears as E:. The 100 Mb appears as C:, the main as D: and the W 7 data as F:.

I am afraid I am going to run into problems here. Any sugestions? Thanks

No.. You should be fine.

XP is just seeing the partitions in the order they are actually in. The partition letters you set up in 7 won't be read by XP the same way.

Thanks. I am going to try.
