Windows Dual-Boot installation issue

Once the drive can be seen, the drive to be selected is “sda”, seen in /dev as sda, sda1, sda2 and sda3. sda is the drive, sda[1, 2, and 3] are the 3 existing partitions on the drive

The detailed instructions from the link in my earlier post should guide you for the rest of the install, as will most of the many posts here about dual boot installs.

Please follow the part about using the windows efi partition and mounting it at /boot/efi without formatting. The efi partition should be sda1, but verify before you use it. It should show as (efi system partition) to the installer.
Everything else can be put into the free space you provided.

Okay I can confirm that RAID is enabled, what is it? and do you know how to switch to AHCI without loosing data?

Thank you!

What’s your machine spec? Can you share a screenshot of the relevant BIOS page? Usually, there is a toggle for such things but they vary between machines.

Got it done! Everything was going smooth, I was following this tutorial when I encountered a problem around step 10. The installer says “Error checking storage configuration”, and doesn’t let me proceed.

So this is my new sticking point.

image of the actual error I’m getting

I tried this option per computersavvy’s thread, but it didn’t make any difference

finally these are some more details I was able to find after setting the partition to efi

Apologies for the different replies, the forum wont let me add multiple photos in a single post

Oh my … !

@imntesta is in a hurry to get Fedora into his machine! That’s good … that’s very good except that hurrying often introduces more problems. Some of those screenshots are quite scary, my friend. Don’t do those.

You need to take the following steps:

  1. You already have three (3) partitions on the SSD (nvme0n1p1, nvme0n1p2, and nvme0n1p3)
  2. Since Windows is already on the Machine, I assume it is nvme0n1p3 (678.32GiB). That means nvme0n1p1 should be an EFI System Partition (ESP). Please note this specifically … You do not need another EFI partition. You already have one. Also … what ever you do, DO NOT … don’t format the existing EFI partition because that will elongate your journey and surely make you despondent. Don’t do it. You are warned!
  3. Create the following partitions on the free space 256GiB (/boot, /, /home, and /swap)
  4. Set the mount-point for nvme0n1p1 to /boot/efi (assuming nvme0n1p1 is actually the ESP … I am betting on it). See? You are only mounting the existing EFI partition, you do not need to create one – no need to format that too.
  5. Now run the installation

How did it go?

Haha I sure am!

When creating those partitions on the free space 256gb, is that something I do within windows disk manager or within the Fedora installer? How exactly do I go about that and how much space should I allocate to each?

Sorry for all the questions, just want to make sure I get this right.

Thank you!

You do that within Fedora Installer please.

The sizes are up to you … but I suggest you reserve about 40GiB to 50GiB for / (root partition). /boot can be 1GiB (512MB might just do since only kernels are stored there but I like overheads so mine is 1GiB. /swap can be 8GiB (I have seen recommendations in favour of twice the size of your RAM. However, this also depends on your computing needs. Fedora may not use the physical swap space if you have enough RAM for your computing needs).

You can allocate the remaining space to /home. Eventually, your data will live in /home. So, it deserves enough space to take whatever you will be throwing in there

imntesta has me confused as to exactly what he is doing and why he is using 2 different machines. He has posted different machine photos here so I cannot be certain we are even giving him correct guidance.


Here he showed he was working on a machine with a standard HDD shown as /dev/sda

now during the install he shows he is working on a machine with an nvme SDD

Those show two distinctly different machines and he is having problems following guidance already given. I am confused!!! :thinking:

It is possible that @imntesta is running the installation from a USB live media. However, I am not sure how ls /dev will represent the live USB. I can confirm that USB sticks are labelled like regular HDDs. My 4GB stick bears /dev/sdc1 as at the time of writing

When running from live USB I see the partitions on the USB as /dev/sdaX, etc. but that would not explain why /dev/nvme0 did not show on his first pic above. It seems that he has to be posting pics from 2 different machines.

See this response.
Some computers ship with hard-drives configured with software RAID (BIOS). Such drives are not detected by Anaconda. In @imntesta’s case, the SDD showed up after he changed the configuration from RAID to AHCI

Ahhhh! :grimacing:
I don’t use Dell, thus am not used to that dell bios so I missed that. Still confused but better. :thinking:

Thank you both for your help! I just got home from work and I’ll be giving your suggestions a shot.

Great news! Fedora is succesfully installed! Thank you both for your time and incredible help.

Now I do have a couple of follow up questions if possible:

First, I noticed fedora is not recognizing my wifi hardware at all because I have no way of connected to wifi from the settings, how can I fix this? On that note how should I go about updating and getting all of the appropriate drivers? This is the laptop I’m using

My second question is that I’d like for the Fedora installation to remain “hidden” at boot, so that windows just automatically boots up and that I can only get to Fedora if I purposefully hit f12 to access the boot menu. Is this possible?

First we need to know which wifi chip you have.
Please run lspci | grep Network and post it so we can see what is there.
Different manufacturers use different chipsets and each require different drivers so to get the proper driver the chipset must be identified.

That would have been easier had you specified that earlier, but we can fix the grub menu to boot windows by default.

This thread talks about how to do this, and I would suggest you read it carefully then make your own choices as to how to proceed.
@chrismurphy in his post near the end of that discussion seemed to have the best solution, and maybe he can give you detailed guidance about that.


Glad it worked out. We are here to help. I believe this thread is now resolved. Please, tick the post that solved your problem as the “Solution”. That way, people with similar issues can find answers without starting duplicate threads. Start separate threads for your new questions since they do not concern Fedora installation. They relate to managing an already installed Fedora/Windows.

Welcome to the Fedora Community. I hope you enjoy Fedora.
