This can be achieved by using a regular USB/pen/thumb drive. The hack would be more than enough to keep even your curious geeky computer friends from booting into the system. That said, it is by no means foolproof , so you might not want to bet your life on it.
DISCLAIMER: the following method requires you to make some changes to your operating system. Please read the instructions thoroughly before beginning and if you are still not sure what you are doing, you should seek help from a knowledgeable friend or abetter avoid it.
Here’re the steps:
- Format the USB drive.
- Within Windows Explorer go to Tools > Folder Options. Within the View tab, choose “Show hidden files” and uncheck “Hide protected operating system files”.
- Open up the Windows Partition (usually C:), copy boot.ini, NTLDR and ntdetect.com onto your USB drive.
- Boot up the system and change the boot order preference to check for a USB device first. You can access the BIOS menu generally by hitting F8 when the computer just starts.
The changes are fully recoverable, although it would require some work for the uninitiated. If something goes wrong or you want to restore back things as they were then use the Recovery Console from your Windows CD.
