So, why I’m I writing about putting in Ubuntu with Home windows 10 as soon as once more? As a result of as of late Home windows 10 Professional model comes with BitLocker encryption and therefore while you attempt to twin boot like regular, it both refuses or creates challenge.

I observed it with my new Dell XPS 13. I purchased the final Dell XPS in France and it was preinstalled with Ubuntu. Sadly, Dell India had no choice apart from shopping for the Home windows 10 model. In a manner, that’s good as a result of it helped me to write down this tutorial.

To be trustworthy, twin booting with BitLocker encrypted disk can also be not difficult. It simply entails the additional step of disabling encryption earlier than beginning the twin boot and re-enable it after putting in Linux.

Don’t fear. I gained’t depart you similar to that with my phrases. I’ll present you every step with acceptable particulars.

Please needless to say I’ve used Ubuntu right here, however the steps needs to be relevant to Linux Mint and different Ubuntu-based distributions as effectively.

This twin boot information is solely for programs which have Home windows 10 put in with BitLocker. Since it’s comparatively a more moderen factor, the steps are just for UEFI programs with GPT portioning scheme. Please verify your system first earlier than following the steps.

I additionally advocate studying all the steps earlier than you begin following it. This may increasingly enable you to find ache factors and chances are you’ll put together accordingly.


Listed below are the stuff you want:

A Home windows 10 system with BitLocker encryption.A USB key (also referred to as pen drive or USB drive) of at the very least 4 GB in measurement and no knowledge on it.Microsoft account for saving the restoration key of BitLocker encryption (exterior USB can be utilized as effectively however MS account might be extra handy).Web connection.Non-compulsory: Exterior USB disk for making again up of your knowledge.Non-compulsory: Home windows restoration disk.A while and persistence (obligatory).

Step 1: Make a backup of your essential knowledge on an exterior disk

That is non-obligatory but advisable. It’s best to make a backup of your essential information on an exterior disk as a result of you’re going to take care of disk partitions.

In case you are unsure of something, I counsel search for paperwork, music, films and different essential stuff you could not lose and duplicate them on an exterior USB disk. You should use an exterior HDD (slower however cheaper) or SSD (quicker however costly).

You might also use a pen drive for copying information and storing it on another pc (when you have multiple system).

If potential, have a Home windows 10 restoration disk with you (non-obligatory)

This one is non-obligatory too however could possibly be useful if something goes unsuitable. You possibly can repair the boot information and restore Home windows.

Earlier than you do this, you could again up your restoration key. It’s a 40 digit key to reset BitLocker encryption. Why? As a result of you’re going to change the boot settings and BitLocker gained’t like that. It’ll ask you to enter the restoration key to make sure that your encrypted disk is in secure fingers.

It’s possible you’ll again up the important thing on an exterior USB disk or to your Microsoft account. I saved it to my Microsoft account as a result of it’s simpler to maintain monitor of the restoration keys at one central place. After all, you could guarantee that you’ve got entry to a Microsoft account.

Confirm that your restoration key is correctly saved by going to this hyperlink and logging into your Microsoft account.

Whilst you look forward to the decryption to finish, you must go on and obtain Ubuntu ISO. As soon as BitLocker is disabled, you’d discover that the lock has disappeared from the drive icon.

Step 4: Obtain Ubuntu ISO

Whereas the disk is being decrypted, you must make the most of the time in downloading the ISO picture of Ubuntu desktop model. It’s a single file of round 2 GB in measurement and chances are you’ll obtain it straight or use torrent when you have a sluggish and inconsistent web.

Step 5: Create a reside USB of Ubuntu

After you have received the ISO, you must get a instrument for making the bootable reside USB of Ubuntu.

It’s possible you’ll use Etcher on Linux, Home windows and macOS. Nonetheless, the best way Etcher creates a bootable disk leaves the USB in a bizarre state and also you’ll have a tough time formatting the disk after the twin boot is over.

Because of this, you’re utilizing Home windows, I like to recommend utilizing a free instrument like Rufus. Obtain Rufus from its web site.

Plug within the USB key. For the reason that USB might be formatted, ensure that it doesn’t include any essential knowledge.

Rufus robotically identifies the plugged in USB keys however it’ll nonetheless be a good suggestion to ensure that it’s pointing to the proper USB. Then you must browse to the placement of the downloaded ISO picture.

From right here, transfer ‘booting from detachable media’ up the order in addition from USB.From inside Home windows, entry UEFI settings and select in addition from detachable media. This can reboot the system and also you’ll be booting from the USB.

I favor the second technique as a result of you could have difficulties in with boot settings from the primary technique.

Within the Home windows menu, seek for UEFI and click on on ‘Change superior startup choices’:

Below the Superior startup choice, click on on Restart now button.

On the subsequent display, click on on ‘Use a tool’:

After you have the free area, repeat the process from step 6. Which suggests boot from the USB and begin the set up process. While you see the Set up kind display once more, go along with One thing Else this time.

It’ll take you to the partitioning display. Right here, you should utilize the free area you created earlier for putting in Ubuntu.

In the event you see grub rescue display, chances are you’ll attempt to repair the boot challenge by booting into reside Ubuntu USB and use the boot restore instrument.

In case you are not in a position to repair the grub error and getting panic assault, settle down. You possibly can revert to Home windows. Go into UEFI boot settings and use Home windows boot supervisor in addition into Home windows. Right here, delete the Ubuntu partition to say the disk area and from the UEFI boot settings, delete the Ubuntu/grub boot file.

In case you are not in a position to boot into Home windows in any respect (extraordinarily uncommon case), it’s time to make the most of the Home windows restoration disk and the backup you had made earlier.
