Thanks for the write up, I'm sure this'll be linked to many a time.
Awesome tutorial @linux-aarhus. I hope you don't mind, I did a minor grammar and spelling revision. I did not change your directions in any way. Just a minor cosmetic polishing. I hope you are not offended.
What if you select the left disk?
Maybe you better set to "correct disk" instead?
I would have corrected myself, but I am too cautious on editing others' wikis nowadays..
Thank you for your editorial suggestions.
I am Danish and English is my second language.
Though it has been in use since 4. grade (my 11. year) and now, at my 59. year, it is not getting near perfect.
So thank you for your contribution.
Is it on purpose that it is suggested to create a second/seperate ESP for manjaro ?
Yes it is.
I do a lot of support in our local community - mostly Ubuntu - and I have noted that a lot of issues strive from the fact that Windows thinks their $esp is theirs.
I have explained why beforehand
The cost of the extra $esp is minimal compared to the benefits.
The benefit is - you don't mess with your Windows partition. Manjaro creates a pointer to the Windows Bootloader and under no circumstances are your Windows boot entry nor your Manjaro boot entry going to dissappear in an update.
You can of course use the existing bootloader - but you are asking for all kind of troubles.
Mk - I was guessing it might have something to do with windoze shredding the bootloader or something, but wasnt sure.
OP has edited in first post to include my link in section [Oh No - It boots directly to Windows]
Appreciate the inclusion. However, instead of booting up after installation to find it boots only to windows, we can, after Manjaro installation, and still at livecd OS find out if there could be any problem.
The following is done at livecd terminal, after installation is completed and applies only to UEFI installation.
Is there an entry for manjaro and at top of the bootorder? 
If none, continue with the following commands.
Lets say the root partition (no separate boot to keep it simple here) is sda5 and the $esp is sda2
sudo mount /dev/sda5 /mnt sudo mount /dev/sda2 /mnt/boot/efi sudo cp /mnt/boot/grub/x86_64-efi/core.efi /mnt/boot/efi/EFI/boot/bootx64.efi sudo efibootmgr -c -d /dev/sda -p 2 -L "manjaro" -l "\EFI\Manjaro\grubx64.efi"
Verify again with "efibootmgr" that 'manjaro' is now listed and at top of bootorder.
 - It is still possible to have the manjaro entry listed and still boot to Windows. In that case, see the link and it is possible that the computer make and model has some difficult setup. See the [Some diificult UEFI setup] in the link to fix it.
I have modified the post to include ^^^^ - it is valuable information and I really appreciate your knowledge in this specific area.
Once again my thanks to you!
I guess this was a typo?
sudo mount /dev/sda2 /mnt/boot/efi
Yes. Thanks. Corrected above.
Frede, your English skills, including grammar, have greatly improved over the past couple years. It speaks highly of your motivation. If only more of us had your enthusiasm!
I would also like to suggest PLOP for computers that do not support live USB booting. I have tested it out on Windows XP/7 and it works just fine. Just run the BAT file and it will do its thing.
22 posts were split to a new topic: Dual boot tutorial - a question
This guide is very good, the idea of separate EFI is a nice solution for preventing possible bootloaders' wars. However, some things should be taken into account:
- The second ESP partition may become visible in Windows, and this is obviously not a good thing, so one might need to hide it with unassigning the drive letter in Windows' Disks utility.
- This is something really important. In case of user's decision to make a reinstall of Windows such user should not delete its ESP. Otherwise Windows fill find Manjaro's one during the installation and make use of it.
Stupid question: I am installing Manjaro on a new laptop with Win10 installed on it. Wanted to keep the Win10 install since the SSD is large enough. Following the guide I realize that the current installer does not automatically create extended partitions. So if I follow the guide as it is, I end up with 5 partitions (Windows EFI, Windows NTFS, Manjaro EFI, Manjaro EXT4 root, Manjaro Swap) which is more primary partitions than possible. Is it me doing something wrong or the guide is slightly imprecise here? Didn't use Windows for over 10 years and therefore always used the Legacy mode in UEFI machines, so I'm kind of a newbie here.
That is a limitation of MBR partition schema.
But on a new Win10 laptop this should not pose a problem as Windows 10 uses GPT partitioning.
If you are using Legacy boot or CSM as it is also called the partition schema will be MBR as this (probably - no knowledge) will be what the Windows installer will choose.
Booting the system without CSM - pure UEFI - should make the Windows installer choose GPT.
Well, the installer reports it to be a problem. It is a Thinkpad X250, so it is 4 years old (it's just new for me since I bought it recently ). Any idea how I should adapt the guide to work with the MBR partition table? Thanks!
Never tried - but as MBR has a limitation of four on primary partitions you need to keep the partition count below four.
You should not need to create an EFI partition.
Using a swapfile instead of a swap partition will further decrease the needed partitions.
But there is an EFI partition already there. The laptop came with Win10 preinstalled and had a large NTFS partition and a small EFI partition already. So it looks like everything is done the UEFI way, only the partition table being MBR rather than GPT... Then Manjaro should also get an EFI partition, right?
