Dual boot Windows 10 and Android-x86

Hello!


Excuse me if this is the wrong section, please move to the appropriate section. My colleague has an old netbook and would like to either install Android-x86 on it or dual-boot with Windows. As I am a bit more advanced, I decided to try it myself so I can help him step-by-step.


The first attempt was to install Android-x86 only in a USB Flash drive. So I removed my test-notebook's hard disk (to avoid any accidents) and proceeded with the installation. I won't go into details as this is not the purpose of this post. After some attempts I did it right and could boot into Android-x86.



Then I wanted to go a step further and dual-boot with Windows. My Colleague is going to use Windows 7, but I had already installed Windows 10 Pro 32-bit on my test-notebook and wouldn't want to format and install 7. Besides, how different it could be using Windows 10? So I loaded Computer Management, then Disk Manager and shrank the Windows partition by about 10GB to make room for the Android-x86 installation. To identify the space easily within Android-x86 Setup, I even created a new simple volume and formatted it as FAT32 and labeled it Android. Within Android-x86 installation there were no partition names, only sizes in KB, but I managed to identify the correct partition and install Android there. When asked I also installed the Grub boot loader to be able to boot into Android and added an entry for Windows. After reboot I expected to boot into Grub and see selections about Andoid-x86 and Windows. But instead I booted into Windows 10! So I thought to use EasyBCD to add a boot entry for Android. Using the Metro interface made no difference and the computer booted into Windows 10 again without giving me any choice. I then loaded EasyBCD again and this time I disabled the Metro interface, so I had the old good Windows 7 (legacy) boot loader. I could see the entry for Android but I could not boot into that. I tried to add a boot entry with Grub (legacy) connected to the Android partition without any success. Then I tried all other available partitions, naturally nothing again. Once I tried to add a Grub2 entry but all I got was an empty list without boot entries, so I saw a Grub command prompt. I know nothing of Grub, so I cannot use this command prompt to boot into Android-x86.


Is anyone familiar with Grub and EasyBCD to tell me what to do? If that helps, in Windows Disk Manager I see 4 partitions and Android is installed in the third partition which is formatted as ext4. In Android Setup I see more partitions (weird) and the Android partition is sda5. Android-x86 was 6.0 RC1 Marshmallow, but I don't think that matters.



Thank you in advance...

Missing Bootable devices in BIOS after removing Ubuntu dual boot

Windows 10 Pro, Version 2004, OB build 19041.572

I have a Gigabyte GA-Z77X-UP4 TH mb. My BIOS has been set to UEFI for a while now and I had no issues with it. When I needed to boot into some live cd or flash drive, I would press F12 at boot and have a list of bootable devices to choose from. I also saw all of these devices in the BIOS, where I could choose them for a boot order.

I found myself using Ubuntu quite often with the “try ubuntu” option, so last week I decided to install it as a dual boot. I used a secondary hard drive for the Ubuntu partitions (not C.) After a few days, I decided to get rid of the dual boot. I went through all the steps to delete it; deleting the ubuntu partitions, and using diskpart to get GRUB removed from the boot loader. Although after this, the computer would boot right into Windows, for some reason, the ubuntu was still listed in bcdedit /enum firmware, so I also used bcdedit /delete to delete that.

Here’s the issue that I have now:

When I press F12 to boot into a live CD (or flash drive), the only boot option is Windows. In my BIOS, in the boot order section, I can only choose Windows; there is no more list of all my drives and CD ROM to choose to boot from.

The only way to get back the list of bootable devices is if I switch the “Boot Mode Selection” from “UFEI only” to anything else, like “UEFI and LEGACY” or “LEGACY only.”

However, if I switch to anything other than “UEFI only,” the computer won’t boot into windows; I get an error saying, “Reboot and select proper boot device.”

I am 99% sure that before I did the dual boot, I had “UEFI and LEGACY” selected in the BIOS and in Windows System information, it would show that my BIOS is UEFI.

What I need now is to be able to see a list of bootable devices in my BIOS, including my CD ROM, so that I can choose to boot from a CD or flash drive when desired, and of course, that my computer should boot into Windows when I just want to boot normally.

Notes:

1. Fast boot is disabled.
2. I read that Secure boot should be disabled but I don’t have that setting.
3. I read that CSM should be disabled but I don’t have that setting.
4. My C drive (SSD) is GPT, Active & System.

Any suggestions?
