Asking advice: Installing mint-19 along side factory installed Windows-10. UEFI is turned off so other operating systems will boot. I have set up multi-booted operating system. However, it's always on older BIOS machines and I was never concerned whether or not Windows survived. This new machine is for my wife and she wants both Mint and Windows. I'm under the gun and require reassurance and guidance. Thanks for your help.

If windows boots with uefi turned off, then will be no different then duel booting on bios machine.
If windows won't boot with uefi disabled, turn back on uefi, disable secure boot and fast boot in firmware/bios, disable fast boot in windows advance power settings. Use windows disk management to shrink windows to make room for Linux.

Great stuff :-) thanks

Researched the Dell support site. Dell has a plethora of help material that is well organized and speaks to my question. However I needed reassurance from the troops in the field :-)



cheers :-)

Just to re-iterate - make sure UEFI is turned on. And always left on.
Otherwise you will have a world of grief on the domestic front.

I take your point to heart. I don't need family turmoil :-)

thanks for the heads up!

cheers :-)

Not sure I understood your initial post as you refer to UEFI being turned off on the computer with windows 10 on which you want to install Mint. Windows 10 default from the factory is UEFI mode on a GPT partitioned drive. I would suggest you read the link below which gives a good amount of general information on dual booting UEFI with windows 10/Ubuntu (or its derivative Mint). Some is specific to Ubuntu but most will apply to both.

Thanks for your post:-)

Studied a great amount of material about UEFI, GPT Partition, and FAT file systems. Thoughtfully and thoroughly, followed DELL instructions in this regard. working though windows Settings, Update/Security, Recovery, Restart, Troubleshoot, Advanced Options, UEFI Firmware, Restart, UEFI disabled, Secure Boot - Off. the same process with UEFI disabled and Secure Boot disabled. played with this and received no-joy:-(

Determined: DVD distros built with UEFI and required GPT partition formatted FAT file system. Also burned distro with Windows 10. To determine whether/not some idiosyncrasy existed there.

Googled for advice, and followed many suggestion: No joy:-(

There was partial success with Fedora 31, however, it crashed and locked up the Dell only recourse -> pull the plug. No joy:-(

An article: [url] https://www.happyassassin.net/2014/01/25/uefi-boot-how-does-that-actually-work-then/ Post has some age to it, yet it gives good insight too UEFI.

I have question: But as I set here thinking - it's too embarrassing to ask :-( No joy !

I have not followed link in your post, but I will, and get back to you :-)

cheers :-)

Not sure what you are referring to here. windows 10 requires UEFI on a GPT drive and will not install on a GPT drive unless using UEFI. THat is not required with the various Linux systems. If it is UEFI, there will be an EFI partition which must be formatted fat12, fat16 or fat32. The windows system partition will be ntfs and the Linux will have some Linux filesystem, many ext4.

You can determine if your windows install is EFI by checking Disk Management on windows ( actually not sure about that? ) or by booting any 'live' Linux and opening a terminal and running the following command in a terminal as root user: parted -l (Lower case letter L in the command, if you are using one of the Ubuntu's like Mint, prefix the command with sudo) It will show the partitions and one should be labelled quite clearly as EFI.

If you are planning on using Mint, you should do an online search for dual booting with windows 10. You should find a number of sites such as the one below.

First you need to determine what mode windows 10 is using https://www.tenforums.com/tutorials/...gacy-bios.html https://pureinfotech.com/check-gpt-m...on-windows-10/
I have seen newly bought uefi systems with windows 10 installed in legacy/csm. What ever mode windows is using is what will determine the mode that Linux should be installed in.

wayne1937,

Assuming your W10 uses UEFI, make sure that:
1. UEFI is ON.
2. Secure Boot is disabled.
3. Fast Startup is disabled.

Then follow this guide:

Thanks for your post.

for my situation, the whole process turned out to be extremely simple. installed both mint19.3 cinnamon and ubuntu18.04.4 along side windows10. 1) turn off secure boot. 2) leave UEFI on. 3) power down machine. 4) load disk. 5) power on machine, when machine first begins its start up - tap f12 several times. boot order screen will appear. script will appear which identifies itself as being associated with the disk to be booted. use arrow key to select script. machine will boot the disk. It took a long time for ubuntu to come up on screen, but after it was up install went quickly. mint came up quickly and installed quicker.

until it was discovered f12 is the f-key to use for DELL to enter BIOS, not much success. before f12 came into focus, it took a long list of clicks and restarts to enter the BIOS. however, Dell finally got there, and that's when Secure Boot was disabled. Much later, after much reading and research and many attempts to boot the before noted two disk, it became an embarrassingly simple process.

an extremely huge thank you goes out from me to all those who give their time and effort to the cause of Linux.

cheers :-)

Hi guys. I just wanted to do a fresh install of Linux Mint 19 and at the end of installation process i have an error: The 'grub-efi-amd64-signed' package failed to install target/ . Any help please?

Since this is a completely different subject, you are better off opening a new thread with the appropriate subject line so people can see it and give you answers. Hijacking an old thread with a different subject doesn't really help you because people scan through subjects to see what they can answer.
