Dell vostro 1000 orig HD 80gb has bad sector. Preformed check disk to mark bad sector and recovered. Purchased a new 160gb HD and used GHOST 2003 to clone the drive. This is a great program and have not had any issues from previous cloned drives. I've actually worked with drives in a worse condition with success. Cloned drive and during process no error's noted, successful clone. When booting up on new 160gb HD, " Error Loading Operating System." I removed drive and installed it as a USB drive can see all data and no errors, all data is there. I ran GHOST a 2nd time. I then used Windows Disk and ran a repair to make sure nothing was missed. Same error. Not sure which direction to proceed. I ran the DISK diagnostics no errors on drive and it will load in CMOS. Current Dell bios ver 2.5.2. I don't think it's a BIOS issue.
