Hello, I am Tanveer Raihan. I am a Mechanical Engineer working in a Power Plant. Recently I have faced a problem regarding the control panel of our generators. The control panel contained an IPC which runs on Windows XP operating system. Recently HDD of that IPC got crashed leaving us in a complete disaster. We have searched that particular model of HDD at our local market but failed. Then I have tried to install the windows on CF card but currently the market is out of CF card more than 4 GB and I think less than 4 GB isn’t sufficient. So, I have no choice left but to use a USB pen drive or Portable HDD. But can any one give me a guide or tutorial about how to install windows XP on the pen drive. I am in badly need here. If anyone can give me anything, I would be heavily grateful.
