Dilemma in installing Fedora in EFI


Trying to install Fedora 27 on sda in EFI and there is no EFI partition on sdb drive which is Windows10.
How can this be fixed ?

The Fedora install on sda is looking for /boot/efi and there is no /boot/efi
on either drive sda or sdb.

When creating / would you make a Mount Point pointing to /boot/efi

Did you install windows 10 or was it pre-installed?
It would be unusual for a "pre-installed" windows 10 to not be UEFI/GPT and not have an EFI partition.

If windows is not an EFI install, then it would simplify things to not install Fedora EFI because if you did, you would have to make a selection on boot to change the drive OS. You might be able to create an EFI partition for Fedora if it is on another drive and use EFI. I haven't used Fedora for years so can't be any more help.

Windows10 was installed on a HP 280 G3 new computer.

I have two hard drives sda is Fedora and sdb is Windows 10.

I was told on a prior post that /boot/efi fat32 partition could not be created on sda, it had to be created on sdb the Windows 10 hard drive.

Fedora27 install is looking for /boot/efi partition before completing install.

Using the Fedora install medium, boot it and open a terminal and run this command as root and post the output here:

Code:
parted -l

Your parted output in the last post contradicts the information you gave in your initial post, that there is no EFI partition on sdb which clearly shows. I'm not sure what the problem is, usually a Linux system would create another directory within an already existing EFI partition for it's boot files. I find it curious that windows is on sdb since a pre-installed would certainly be on sda. Are you trying to keep windows and Fedora separate and don't want Fedora files on a windows drive? That might work, I'm not really sure.

I think Fedora doesn't automatically setup the efi partition, during partitioning. If I remember correctly, you have to select the efi partition you want to use, then fedora installation will do the rest. If you want a separate efi parition you will have to create it during partitioning. If you are going to use the one that windows is on just make sure it will not be formatted.

What command would i use to tell Fedora to look at the Windows drive for /boot/efi ?

I could put the Windows drive on sda and Fedora on sdb if needed.

The reason I'm using two drives is because the Windows10 drive is only 500gb and the
Fedora drive is 2TB, I'm trying to upgrade Fedora to 27 but the /boot/efi is giving me problems because Fedora can't find /boot/efi

You might take a look at the link below which is a tutorial on installing Fedora 25/windows 10 UEFI. I doubt the Fedora installer has changed much but you should be able to see if there are any differences from your install. Note that different existing partitions are shown in the installer, using the manual partitioning option. This should include the efi partition. The problem might be that the efi partition is on a different hard drive, although I really don't know why that would be a problem. Well, good luck with it.

Would the command mkconfig -o grub help fedora find the /boot/efi partition on sdb/Windows.

But I'm not sure how to type out the command.

The "grub-mkconfig" command will be run at the end of the installation to create a boot menu on Fedora.

In the link I posted, figure 6 should show the partitions on the drive(s) including the EFI partition as shown. On the right side of the window, there is a Mount point box to enter /boot/efi so if you don't see that, I'm not sure what you would do. After selecting the drive on which to install, do you click the radio button on the bottom of the page "I will configure partitioning"?

Yancek:

Are you suggesting I should have a /boot/efi on each drive.

I tried that before and Fedora on the install and Fedora still could not find /boot/efi.

Having two different Hard Drives is a problem here with EFI.

According to the information in the link I posted, during the installation of Fedora you should see an "Installation Destination" window which should show both drives. If you select the one on which you have windows, do you see an efi partiton on the left side of the new window. If you do, you could select that and then find some way to select the other drive for your / and other partitions. When you click the Done tab in the upper left of that window, do you go back to the Installation Destination page? Or on the right side of the manual partitioning window, can you change the drive by clicking the Modify tab on the right and go back to select the other drive?

Quote:

My understanding is that this is possible, at least with some systems but have not done it myself. So if you tried it previously, did you boot the Fedora installer and open a terminal and as root create a partition on the drive you wish to install to (500MB or less) and format it FAT32 and label it /boot/efi? What exactly did you do if not the above?

If you can't perform the steps I outlined in paragraph 1 above, I have no other suggestions. Try the Fedora Project or Forums sites if you have not already done that.

Everyone is telling me not to format /boot/efi fat32 partition, boy!!! am I beginning to get real confused.
I do appreicate everyone's help but the info I'm getting has to do with one hard drive, The one hard drive , Windows10 is not big enough ,500gb, which is not big enough with volume of data I have in Fedora.
I'm sure some will come up with the solution if they will put on their thinking cap.
I will make another /boot/efi fat32 partition on my Fedora drive but I'm still confused about the Formatting the partition.

You indicated previously that you created an efi partition before and Fedora couldn't find it but give no details on exactly what you did?
Do you not understand that if you format the current efi partition for windows you won't be able to boot anything.
If you create another efi partition on the other disk you would obviously have to format it FAT32.
Going back over my posts I see that I asked you 5 specific questions in an attempt to elicit specific information from you. You have provided NO answers to these questions so, good luck.
