windows10 has disappeared after installing mint, unable to boot either os.


I installed mint cinnamon yesterday after watching good installation videos and following all instructions. I made a bootable flash drive with iso file obtained from the mint website's torrent link and then installed, giving mint about 400gb and left w10 about 500gb. Mint started as promised but when I went to use the keyboard in the menu, mint crashed, restarted, and kept crashing when I touched a key. So I shut down, restarted and couldn't stop w10 from booting, grub didn't show up. So I went into bios, changed the boot order, restarted, and got "no bootable device" on the screen. Back to bios, windows has disappeared from the boot list and no sign of mint. I'm having to use the flash drive because my pc can't find either os. I've run boot repair from the terminal and nothing works. Ideas anyone? Thanks...

Acer aspire E5, about two years old, amd harddrive.

You should be following the instructions on Linux Mint's website rather than watching videos.

How? What did you do exactly? Details, details, details - they matter!

That suggests you have done something your not talking about here. And that the Windows boot manager is installed instead of GRUB.

This suggests that when you changed your BIOS settings, it's trying to find an OS on a drive that does not have one installed on it and/or something's happened to it's boot loader. Which isn't surprising given what you've said earlier.

Can you post more details about exactly what you done that led to all of this.

Also, could you post the output of the following command:

Code:
lsblk
(use CODE tags)

Since you already have the boot repair software, it has an option to Create Bootinfo Summary and selecting that option and posting a link to the output might be useful.

If you had a default pre-installed windows 10 it was probably UEFI/GPT and you would need to install Mint UEFI also. Without the bootinfo output everyone will just be guessing.

Thanks for the responses.

After enjoying mint from the flash drive, I decided to install it and clicked on the install mint icon, and then followed all instructions. When I restarted my pc, grub appeared and I clicked on mint and it booted no problem. A notice appeared saying network connections were available and I noticed mint wasn't connected to the net. I clicked on menu, put the cursor in the text field, and the moment I pressed a key, mint crashed and asked if I wanted to restart. This happened over and over, so I shut down the pc, started again and no grub, windows starting instead, and after trying several times still no grub, so I went to bios and put windows at the bottom of the boot order, restarted and still no grub, went back to bios and windows had disappeared from the bootlist and I couldn't recognise anything related to mint.

Anywho, I got a w10 iso file and did the repair thing and I now have w10 back, so that's better. "this pc" shows my c drive at its reduced volume and no other info. I'd rather be using mint...

You can run "lsblk" from the Mint install media.

If you can boot the Mint install media and run boot repair again it will give a lot more information on possible boot problems.

What does your partition table look like?

Can I run the flash drive while w10 is running?

You need free space unallocated space for Linux to install on. Let Windows have the first part of a hard drive. It has probably 3 partitions and one that boots everything called an EFI that it will share with Linux boot system. I'm guessing you are using UEFI instead of legacy mbr.

Here is the Linux Mint User guide (shows install steps): https://linuxmint.com/documentation.php

The boot repair output will show all the information asked for by other members and is the simplest step since you have alread used it once. Running it from windows won't work, you need to boot the Mint flash drive and run it again.

Hint: If you are a Linux novice and need to dual boot it with Windows, you might find setting up Windows boot from Grub to be complicated. Just get rEFInd, install it after reading the docs (from either Linux or Windows), and it will boot both Windows and Linux fine.

I'm using uefi because legacy didn't work before, except the first time, then it disappeared.

Yes, I followed that guide.

Rad, can I use the manager to delete mint from the 400gb I gave it, and then try to reinstall?

Yes you can delete that partition with that program & install mint again in the unallocated free space. Information for installing Linux Mint is page 15-16 in the user guide. Also this covers how to setup your partition for Linux Mint when installing it: http://linuxbsdos.com/2015/08/18/how...uefi-firmware/

If it has installed in the 400 gb you might want to see if you can boot that partition with your Linux Mint installer. I cannot find information on it. I've never used Linux Mint nor setup Grub. There is an issue somewhere. In bios is secure boot disabled for your computer? Is Grub selected as your boot loader in bios? Maybe do this:
http://ubuntuhandbook.org/index.php/...ntu-wont-boot/

If you manage to boot your Linux Mint hard drive & are using efi instead of mbr you can use sudo efibootmgr in the terminal to set boot order in Linux Mint so Grub is first.
