Notebook Boot and Lockup

Windows 10 + UBUNTU 17.10 dualboot on HP Envy x360 u000.

After installation, I am not able to make any changes in BIOS. The settings are not "Default". Secure boot is disabled.

I have tried the following things:

1. Wipe my HDD and tried to install Windows 10 again - `Windows could not update the computer’s boot configuration. Installation cannot proceed`
2. Tried to install UBUNTU - `[ 0:000000] [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x52 (or later)`
3. Also tried to boot UBUNTU live - same error as above.
4. Tried to update/reinstall the HP BIOS firmware with HP BIOS Recover USB - `Error code : 4(0x00000004)`. I tried both the ways. from windows and with bootable USB. got the same error
5. Removed battery and hold the power off button for 1 min. No luck.

Now I am totally stuck here.

I had my old HDD with windows 8 on it and I upgraded with a new SSD but I haven't done anything with my old HDD. So now I am using my laptop with that HDD. To boot windows I am doing manually EFI boot. Still not able to repair the bootloader on that too.

***Update 1 (12-7-2017)***

So, I am able to boot from UBUNTU 16.04 live USB

1. Tried to repair with `Boot-Repair` - No luck
2. Tried to remove/delete bootloader entry with `efibootmgr` but I can't do anything. every time I got this error `Permission denied`
3. `sudo efibootmgr -v` gives all the details of my SSD (volume ID and all), which I have used to install UBUNTU 17.10 where all the problems occurred in the first place. I am getting the same output even if I removed all the Drives from the motherboard.

So, everything written into BIOS is write protected. I am not able to do anything about that.

The issue is affecting lots of Lenovo laptops, found here.

The issue is also verified by Ubuntu community and They have disabled the download link because of this issue.
