installing XP as duel with vista

[Guest]

Trying to install XP displayed long error message. I'm adding only few lines
as below:

"check to be sure you have adequate disk space. if a driver is identified in
the stop message, disable the driver or check with manfucture for driver
update.

Check hardware vendor for any BIOS update. Disable BIOS memory such as
chaching or shadowing"

any solution?

Forget all these, will I be able to install XP if I format particular
partition?

Vista got crashed. Neither I'm able to reinstall nor recover. Vista is
demanding some driver to access hard disk. I don't know what kind of driver
need to provide.

Even it is not recognizing partition C: (where vista was installed) to
recover. If I try to re-install it is not recognizing partition type (NTFS) .

Can anybody suggest me how to get out of it and install XP. Its hard to say
"if format of partition C: help to install XP, I'll do it"
