Before of all of this, that's what I did :
- Disabled "Secure Boot" and "Fast Boot" options
- Created a disk partition, free space of 50GB
- Used a live USB
- Programs used : Rufus, Win32DiskImager
- Installed the ISOs from the official websites
My PC : - Lenovo Ideapad 320-15IAP the specs are these :
Anyways, at first, I've attempted to install Ubuntu.
I've used Rufus to write the ISO on usb, with the ISO option, the newest Ubuntu release (Bionic Beaver). Also, I did this in EFI USB Mode through Windows Advanced Options (if that's what is called)
So I what I did during the installation :
- Used network, Normal Installation
- chose the option "Install along side with Windows 10"
and here it goes, it got stuck at installing 'grub2'.
When I say it got stuck, I mean it was like that for ages.
Well, I've decided to power down the laptop, it booted up straight to Windows 10, formatted the partition and gave it a try again. Still same results. I used the "Something Else" option as well, but same bad luck.
I did leave it for a day, hoping that it'd install but nope. Also, tried to install it without Wi-Fi, still nope.
I swear, I've tried every possible way to install this xD
As a result of all this, there's a boot option of ubuntu now, which looks like this : http://terminalinflection.com/wordpress/wp-content/uploads/2012/10/GRUB-Ubuntu.png
Could that be a way to repair the lost ubuntu? Uh, the partitions are already deleted. So, I guess it wouldn't work, anyways, as part of the solution of this problem, how can I get rid of this boot option ? Or else, is there a way to rescue this poor thing?
Soooo, I gave up on Ubuntu, wrote Kali Linux 2018.2 on usb, ran it as EFI USB Mode, normally, I was expecting it to have a "Graphical Install" option as many people recommend to install it that way, but it had a "Start Intaller" option, so I went with that option, everything went "almost" well, so as you have already guessed, this 'grub2' stuck, again and again.
( NOTE2 : I've used Rufus to write ISO for Kali Linux EFI, but faced a problem during installation something related to CD, can't remember exactly. Went for DD option instead the problem with the CD was solved, but the 'grub2' was not. But then used Win32DiskImager, still same issue.)
I did the installation of Kali Linux again but with Legacy Mode this time. Graphical install, the installation went fine af, BUT, it now boots up straight into Windows 10, without any boot menus, as expected "grub menu".
The 'ubuntu' as mentioned earlier still exists as a boot option. The partitions that were created in Kali Linux Legacy mode during installation which was partially successful, haven't removed them yet.
I don't know what else to do, someday I swear I will remove this Windows 10.
I would like to have an explanation of this whole 'grub2' thing, both Ubuntu EFI and Kali Linux EFI stuck at the same step.
I came cross to an idea that EasyBCD could restore the missing Kali Linux legacy grub menu. I'm going to give it a try right now, I will keep you updated.
[UPDATE 1: As I said, I'd try out EasyBCD, uh because Windows is in UEFI regardless if the system is in Legacy mode or not, can't make any changes or add a new entry, so yeah...]
