Hi Ms. Debleena,
I got the same problem with Ms. Agnes,
"Windows has encountered a problem communicating with a device connected to your pc. This error can be caused by unplugging a removable storage device...,or by faulty hardware such as a hard drive or CD-ROM.Make sure any removable storage is properly connected and then restart your pc.
File:\Boot\Bcd
Status: 0xc00000e9
Info an unexpected I/O error has occurred."
I already followed the procedure you mention (Step #3) but still got the same problem, it does not fix the error.
One factor i think was it asked me to load drivers something like that cause my windows7 doesn't appear in the list when i tried to do the System Recovery Options. I don't know anymore what to do. Oh by the way my unit was Samsung N148Plus Netbook.
Thank you & regards.
