Remove Lenovo G770 Hard Drive

2012-12-06 replace hard drive with SSD

Since I have to remove the hard drive to install Chameleon to dual boot Windows 7 & Lion, I documented the procedure for later if I need to do it again. The hard drive on my Lenovo G770 is 750GB Western Digital Green (this may be the problem why dual booting with EasyBCD doesn’t work). Anyhow, this is the way I did mine.

1. Remove battery, charge cable, make sure there’s NO POWER connected. Ground yourself to make sure there is no static charges that can damage electronics components.

2. Remove the plastic cover with 2 removable bigger screws and 4 small attached screws (have locks on screws).

back plastic cover     remove 6 screws

remove 6 screws     remove 6 screws

remove 6 screws      remove 6 screws

remove 6 screws      lift the back cover from left up

There are 2 screws holding the hard drive and bracket to the chassis, remove these 2 screws and slide the case out (toward the front)

remove 2 screws      slide the case back (toward the front)

Lift the hard drive and bracket out, there are 4 screws holding the hard drive to the bracket, if you have usb sata external adapter, to connect you don’t have to remove the bracket, just leave everything and connect to the usb adapter. But if you want to replace the hard drive, remove the 4 screws, take out the hard drive and replace with a new one. AGAIN, MAKE SURE TO GROUND YOURSELF (touch some computer case that plugged in-grounded or wear ground strap to pc case).

All the grounding yourself is a good precaution on working with any electronic devices. If you work next on a computer, lamps, anything that electrical with metal case plugged in to AC socket, considered grounded. When you touch these cases, metal body, you’re discharged any electrical static charges through earth ground.

Be safe,



  • If I change the hard drive and put in a larger drive does the system auto discover the change or do I need to go into the bios and change the drive settings?

    thank you


    • It should detect the new drive capacity automatically, no need to configure in the bios, but you can go to the bios to see if the drive is there.
