This depends on the size of the hard disk. Right click the drive in Computer and see what the Properties say - 149Gb will indicate a 160Gb disk (don't ask - I don't get it either). If the disk is large enough to Partition into separate pieces, one for each Operating System, go ahead.
If you have a 160Gb or a 250Gb or larger, give XP about 80 and the rest to W7.
The only drivers from Dell for that laptop are for Windows 7, not even Vista. It's very very very unlikely that the laptop will work properly on XP. You'll probably be able to boot off XP, but video, audio, webcam, etc... won't work.

I just did. Custom XP CD with newer drivers and switching it from AHCI to ATA in the BIOS. Now that part is the easy part, most laptops work like that.. But it still failed several times but finally I got it by disabling Intel SpeedStep in the BIOS as well. The drivers aren't a big deal for me but then again I've put XP on a large amount of computer that are older than 2010. It's not easy, and this would be one of the more difficult models.
One thing I hate is the amount of people that don't know the answer but still fill up message boards with junk responses. Everybody has to have attention it seems.
