Nevermind, I don't have a Windows XP disk. It came installed with my computer. My computer has been working fine the past like 5 hours, but it hasn't done much. I think it will be okay.
If your computer has the facility to make a restore CDR(s) or DVD from a hidden partition or FAT32 partition on your hard drive you should do this at the first opportunity.
This computer had a 5 GB hidden partition and some new computers have a 15 GB FAT32 partition. The latter will show up in Disk Management.
The former may be determined by mathematical calculation if you know the nominal (or decimal) size of the hard-drive from which the binary size may be calculated and any apparently missing space, other than the numerical size reduction, caused by formatting will most likely be a recovery partition.
E.G. A 100 GB hard drive will be 93.13 GB (binary) after formatting.
