YANCEK !

It isn't going to work !!

On the Fedora hard drive I created a formatted /boot/efi , mount point /boot/efi.

And still the install of Fedora 27 can't find /boot/efi.

If I take the Windows drive out of computer and convert the computer to a Fedora system, do you think I will have problems of installing Fedora, I mainly want a Fedora system only.

I'm convinced that UFI won't work with a TWO Drive system.

I'm not sure what exactly you did so I have no idea why it "didn't work". You haven't responded to previous questions I've asked so there isn't much I am willing to do except to point you to the link below which explains how to dual boot windows 10 and Linux (Ubuntu in this case) on two separate drives with two separate efi partitions. All I could suggest is that you read it as the process should be the same in Fedora if you have GParted on your Fedora.

If you want to share the windows efi partition with fedora, during the partitioning stage select custom select both drives, select the partition on sda you want to use as /

Find the /sdb1 (windows efi partition) set the mount point to /boot/efi, do not format.

If your intention is to use the sda1 boot partition as the efi partition for fedora, you will need to format it as fat32, flag it as an efi(ef00) partition type, and set the mount point to /boot/efi

okay we'll give it another run at it.

First,on the HP 280 E3 setup.
Secure Boot;
Legacy Support - Enable
Secure Boot - Disable
Fast Boot - Enable

And now on the Windows10 hard drive you say don't Format the /boot/efi how can you verifie that, it is't already Formatted.No!! I did not touch that Partition.

And final, the / Partition should have a Mount Point /boot/efi assign to it.

How do you do you set Mount Points in Gparted ? KDE Partitioning does a better job at it.

Guys, this /boot/efi is totally new to me, and I do appreicate your help, I do have to install a lot Fedora on the DAMN Windows 8, 10 boxes for my family and friends, believe me I have converted a lot of them to Fedora. Please come back with Windows 7 . Life was so simple then.

I'm getting to Damn old at 77 to have to contend with Windows anymore.

Are you booting the installer in legacy mode or efi mode? It is better to boot same as windows in efi mode so disable legacy support.
You don't use gparted or KDE partitioning to set the mount points. This is done at the settimg up of your partitions stage during the fedora installation.

Your root partition will be at / and the efi partition you want to use will be at /boot/efi

Your root partition will be at / and the efi partition you want to use will be at /boot/efi[/QUOTE]

[U]nderstand, but do I setup a /boot/efi inside the / partition at Fedora install ?

No, just set it as the mount point and the installation will auto create the /boot/efi, at least it did the last time I installed Fedora in EFI mode.

Yancek, I ask in a previous question about the settings below and ColorPurple responded with the answer about how to set them correctly, but his answer does not at this time show in this thread,is there a way to retrive that answer ?

Thank you.

disable fastboot, disable secureboot, disable legacy support to boot in efi mode. Need to use a 64bit iso for efi mode.

colorpurple21859,
I moved the Fedora drive from sda to sdb. Windows 10 is now on sda and Fedora is on sdb

I'm still having problems, can't find /boot/efi , I made a /sdb4 vfat partition and formatted it to a /boot/efi system in the Fedora setup, should I have formatted to a vfat partition ?

The above changes where also made, your point "to boot in efi mode" I assume that by making the three changes above it will auto boot into /boot/efi , yes or no ?

/boot/efi is the mount point for sdb4 and should be an entry for it in your /etc/fstab. The file system that you format sdb4 should be fat32. partition type for sdb4 should be esp.
Did you get any error messages during the partitioning stage of the installation?
What files are on sdb4?

The Mount Point /boot/efi on sdb4 and partitioning in vfat or EFI System format, I still get a error message:

"No Boot Loader Device found, You must include an EFI System Partition on a GPT formatted disk"

This is the whole problem of getting Fedora installed on this HP Windows 10 computer.

I have not touch the EFI partition on sda in Windows10 system.

I,m beginning to believe that this HP 280 does not like to have Two Drives installed in it.

According to the message sdb needs to be GPT instead of msdos. You may be able to convert sdb to GPT with gdisk without any data loss.

edit: while in gdisk change sdb4 partition type to ef00 also if it needs changing.

(quote) edit: while in gdisk change sdb4 partition type to ef00 also if it needs changing.

Is gdisk on the Live DVD, I have never used gdisk, I have all my Data files on sdb, if I format
to GPT will I loose the /home directory ?

Does changing partition to GPT Effect all the partitions or just the drive as a whole ?
