Are you encountering STOP errors while upgrading to Windows XP from Microsoft Windows 2000? Is setup process getting terminated halfway and you can not access even the Windows 2000 operating system? This behavior of Microsoft Windows renders your system completely inaccessible, as there is no working operating system on your hard drive. At this point, all of your Windows hard drive partitions become inaccessible and you come across significant partition loss situations. To recover lost partitions in these cases, Partition Recovery is required.
As an example of above mentioned problem, you may come across any of the below error messages, while upgrading your system to Windows XP:
STOP: 0x0000007B (parameter1, parameter2, parameter3, parameter4)
Setup has encountered a fatal error that prevents it from continuing.

Setup cannot continue. Power down or reboot your computer now.
The error message may also occur during setup process, when your system reboots during installation process. You can try out following things to fix this problem and perform :
Boot Sector Virus- The above STOP error occurs when your system gets infected by boot-sector virus. If you can boot your system, use an updated anti-virus software to scan the hard drive and remove the viruses, if it finds any.
Device Drive Problems- You may encounter this behavior due to damaged device driver of boot controller, damaged information in Windows registry, and boot controller is not configured. MS Windows XP needs a mini-port driver for communicating with hard drive controller. You need to replace the damaged driver from Windows XP boot CD.
Resource Conflict- The problem may also occur because of resource conflict between another controller/SCSI devices and the boot controller. To resolve this issue, contact hardware vendor.
If an anti-virus application can not remove the boot-sector virus, you need to repartition and format the hard drive and then reinstall Windows XP. This method removes all the existing Windows hard drive
