I want to back up the system disk (C: drive) of my computer. It is a small 20GB harddisk. I use Paragon Backup & Recovery™, version 10.1, build 9169 (01.12.09 ) Free Edition. The OS is Windows XP SP3. Producing the backup copy appears to run fine, no errors reported. Then I Restore this backup onto a different 20GB disk. Seems also OK. But when I try to boot from this newly restored disk, an error message is produced early in the boot right after POST: "NTLDR is missing. Press Ctrl+Alt+Del to restart" The same happened when I used V10.0, but not with V9. When I check the root directory, the NTLDR file not missing and it is not corrupted. I have also tried setting the HDD Raw option, but same error. Any ideas on how to handle this problem?
