How do I retrieve lost .mdb after reinstalling xp mode in windows 7?

I was having problems getting virtual xp mode to boot on my windows 7 computer. I deleted windows xp mode and reinstalled it. I was then able to open xp mode but when I opened Acess 2003 and looked for my database for my business It seemed to have disappeared. Did searches in xp mode, on windows 7 in all drives. Found many other older access mdb files but not the most cureent one. Pleas help. Info in the file dates back over 10 years

I'm really not a person that can answer your question, because I know nothing about XP Mode. However, your use of the word "deleted", rather than "uninstalled"
, makes me wonder if you looked in the Recyle Bin? Since I imagine that you did, I would suggest using a program designed for recovering lost files, like O&O DiskRecovery. It costs about $100, but a file containing 10 years of data might be worth the cost.

EDIT: There are freeware recovery tools available, but I'm not familiar with them, so I can't recommend any of them.
