In computer science, a cache (pronounced /kæʃ/) is a collection of data duplicating original values stored elsewhere or computed earlier, where the original data is expensive to fetch (owing to longer access time) or to compute, compared to the cost of reading the cache. In other words, a cache is a temporary storage area where frequently accessed data can be stored for rapid access. Once the data is stored in the cache, future use can be made by accessing the cached copy rather than re-fetching or recomputing the original data, so that the average access time is shorter.
A cache has proven to be extremely effective in many areas of computing because access patterns in typical computer applications have locality of reference. There are several kinds of locality, but this article primarily deals with data that are accessed close together in time (temporal locality). The data might or might not be located physically close to each other (spatial locality).
There are several different technologies that use the term file shadowing, but the intent of file shadowing within these technologies is to provide an exact copy (or mirror of a set of data).
For file shadowing to be effective, the shadow needs to exist in a separate physical location than the original data. Depending on the reasons behind the shadow operation, this location may be as close as a second harddrive in the same chassis or as far away as the other side of the globe.
try a system restore, or last good known configuration by tapping F8 key during boot up make sure you boot to the correct drive during boot up as default is drive c the hard drive and not D; the cdrom which will not let your recovery disks run you can either reset it in bios or during boot up hit F11 or F12 to get boot menu check with manufacturer to know for sure
after that its data recovery time
but also Reset BIOs to factory settings that fixes a lot of issues with updates
