Printable version of Format XP. updated 3-20-05 If you currently have an XP CD (not Restore media supplied by the OEM) and simply want to Clean install XP, select the Clean Install link below with a step by step guide to Clean install XP. Before formatting a hard drive, make sure you have backed up all the important data and anything that cannot be replaced from other sources. Need a boot disk? You can get images to create all types from www.bootdisk.com. Hint: It is usually not necessary to format XP to correct a problem. You should first try to find a solution from the Microsoft Knowledge Base, the Microsoft newsgroups, manufacturer web sites or if you suspect a virus, get the latest virus definitions from your AV manufacturer's web site; you can also run one of the many free web format virus scans. As a last option before resorting to a format and reinstall, a Repair Install will usually fix file corruption problems and leave your applications and setting intact. Updates not included on the XP CD used for the repair install will need to be reapplied and should be applied before connecting to the internet. Updates can be downloaded and burned to CD media prior to the Repair Install or clean install. The alternative to applying the SP updates after the repair or clean install is to slipstream the updates into the XP CD. Check for links in the Clean Install link below as they will be the latest updated links for slipstreaming. The Repair Install is not a fix for and will not remove a malware or adware problem, but it will restore files affected by the malware or adware applications after they are removed. Repair Install http://michaelstevenstech.com/XPrepairinstall.htm Clean Install http://michaelstevenstech.com/cleanxpinstall.html XP FAQ http://michaelstevenstech.com/xpfaq.html __________________________________________________________________________________ Identify the file system you are using. To identify, follow the steps below: 1. Double-click My Computer on the desktop or from Explorer right click the My Computer Icon. 2. Right-click the disk that you want, and then click Properties. 3. Look for the File System entry. * If the disk is formatted in NTFS, your options for returning to Windows 95, Windows 98, or Windows Me are limited. The Win 9X based operating systems do not read or recognize NTFS, and you cannot convert the disk to use the FAT or FAT32 file system. The bootable disk that you use and the drive on which you want to install Windows 95, Windows 98, or Windows Me cannot use NTFS. Microsoft does not support any third-party solutions for converting NTFS to FAT or FAT32. * If the drive is using the FAT file system, you can install any operating system. If the drive is using the FAT32 file system, you can install Windows 95 OEM Service Release 2 (OSR2) or later.

One notice of interest though, is that the XP Home version does not have a Repair XP option, only XP Pro has that abilility. Also, when you format the hard disk drive, it's very critical to use a Win98SE boot disk with the FDISK utility to delete the partition, create the new partition, and make it active. This will insure a trouble free clean install of the new OS.
