If your hard drive goes bad on your computer, you simply just have to replace it with a new one. Then, install the Windows or Mac operating system and possibly recover files from the bad drive. What do you do if you have a tiny laptop that is hard to open up for replacement? Well, you can bring it to a certified hard drive replacement specialist or you have another option: boot to an external hard drive.
Instead of taking hours to open up your portable laptop, you may direct your laptop to boot to an external hard drive. Most newer computers are able to handle this and you may check to see if this option is available in the BIOS. In the BIOS, there will be options in sequence what to boot first: CD-drive, hard drive, network, USB drive, etc. If there is something that says USB, secondary or external drive, you’re in luck. Just make sure you direct your BIOS to boot to your external drive first and then let your operating system disk do the rest.
