Ok a friend of mine owns a store and his POS PC went down. It had no power what-so-ever. The PSU tested fine, so we through a new motherboard in it. We couldnt find the exact original board as this is a Socket 462 antique board. (He will be upgrading the whole system soon we just need the info) When I put the new motherboard in the pc boots up and says "error loading operating system" I put in a XP disc and tried to do a repair installation it gets all the way up to the first reboot where it should go into the GUI part of setup with 39 minutes remaining, but it never does. Upon that reboot it immediately says "Error loading operating system" I have done much google searching to no avail, many sites say make sure LBA mode is checked in the BIOS, well this BIOS doesnt allow that. Other sites say the drive geometry is too far gone and there is no hope it will need to be low level formatted. Well I used an Acronis boot disc, copied an image of the hard drive onto a perfectly working machine. Tried a repair install of XP on it, and get the exact same symptom! So this to me rules out hardware issues. The data he needs from this POS is apparently not extractable by throwing the drive in as a slave on another PC. The POS company says you must go into the POS system and export it for the data to be any sort of usable. So any suggestions would be greatly appreciated!!!
