[RESOLVED] XP will not boot: Invalid Partition Table

[Shinma]

... How do I do that please...

You can read/copy the part number displayed on the hard drive.
Conduct a corresponding web search. If unfamiliar with process, post the number here. Someone should be able to identify it for you.

Hard drive diagnostic utility should be available from the hard drive manufacturer's website.

... can I access that from REATOGO?? ...

I do not use that software, so unable to assist.
