Boot (turn on) the notebook from the Lenovo button (has a ^ next to it) that is either on the side of the notebook or near power button. Check BIOS settings, try changing from secure boot to legacy.   If boot normally, then download updates again, reboot into BIOS and change back to secure boot.

 

This worked for a few others after the latest round of Windows 10 updates were installed out of sequence.

Re: G50-45 - Will not boot up, continuous restarts.

The problem was that I could not get the computer to start the bios. So tabbing the recovery button ore pressing f12 did dent help.

But I tried to change the hdd, and that help. The old hdd I broken, It will not work on the other computer either. But the new hdd is working on the Lenovo. I have now restored the computer, and all seems to work again.

I used this laptop for 3.5 yrs (Win 8.1, 64 bit) & this problem of restarting several times even from the Novo button appeared recently.

After all the usual methods that didn't work I updated the BIOS (a2cn45ww.exe) from 2.08 to 2.13. This update file is available online & the procedure is simple. This solved my problem for good. (The power supply, battery pack, memory, HDD are all good).

Re: G50-45 - Will not boot up, continuous restarts.

I would go with a Seagate drive (new) if possible and try that for a change. Also - make sure you are matching the specifics (speed, connection and size) of the original drive if possible.

Using old (used) hard disk drives can be a problem all by itself, and may actually hide the underlying cause of disk failure from troubleshooting efforts.

Spinning drives die randomly from all kinds of failures, usually if "sooner than expected" it is due to rough handling more than any other cause. Bumps, drops and jolts to the computer can cause the hard disk to wear unexpectedly and will hasten the failure rate.
