I adjusted the partitions of my lenovo g480 and accidentally deleted the hidden partitions. I restarted and the laptop just boots up with a blank screen.
I tried pressing the novo button and the selection menu shows up. Whatever I select on the popup (normal startup, bios setup, boot menu, system recovery), nothing happens; and all I'm left is a blank screen.
I tried connecting the laptop into an external display and still nothing shows up in the external display.
I tried removing the battery and the 30s power button pressing, and it didn't work.
Need this laptop for work. Hard disk when used in another computer the files are still there.

After removing the AC adapter, battery, and HDD, can you try to hold the power button for 20secs to remove residual power again on the machine. When finished, plug the AC adapter only then power up the machine and try accessing the BIOS via the F2 key or Novo button..
If successful, hit F9 to load defaults and hit F10 to save and exit. On another machine, connect the HDD and backup your files then format it. When finished, put back the HDD on the G480 and boot from a Win7 installer via the F12 key to reinstall Windows 7.
if the G480 came preloaded with Win7 Home Premium 64bit, reinstalling this same OS will automatically find the product key that's embedded in the motherboard and will activate your copy of Windows.
If the above steps doesn't help then there's likely a problem with the BIOS and needs to be reflashed. I would recommend you check these authorized service centers and report the issue:
