[SOLVED] installed fedora-24; unable to boot into windows-10

schneidz · 06-28-2016, 08:26 AM

[asus vivomini vm65] hi, i had to hack around with the bios in order to get it to boot up the live-usb. when i restarted fedora, the grub menu didnt list windows-10. here are my partitions:

Code:

[schneidz@xbmc ~]$ sudo fdisk -l

does anyone know what i can try ?

The partition sheme is not very practical.

You should create a new partition sheme:
1. /boot 1GB
2. swap 1,5 * RAM size
3. / 50-100 GB
4. /home 50-100 GB
5. /var 50 GB
6. /tmp 50 GB

And when you can´t boot into Windows, then you should check grub.cfg.

i tried running grub2-mkconfig but it doesnt pick up anything windows related.

edit:
i manually added this to grub.cfg:

Code:

menuentry 'Microsoft Windows 10' { set root='hd0,gpt1' chainloader /EFI/Microsoft/Boot/bootmgfw.efi boot }

but when i select it grub instantly highlights the 1st choice (fedora 24) and restarts the countdown.

There is no entry for Windows 10.

http://askubuntu.com/questions/56449...e-not-detected

or search with Goooogle for Grub2 add Windows 10

thanks, my edit above.

edit:
i tried typing in the commands manually into the grub command line.
when i try to run this:

Code:

chainloader /EFI/Microsoft/Boot/bootmgfw.efi

i get invalid signature.

a little clarification, the bios menu was very confusing but i think i had to disable secure boot, and enable legacy mode and csm compatibility modes in order for the pc to boot from a usb. the windows-10 came pre-installed from the oem but it is not able to be booted now (even when i try to reset the settings in the bios). although i am able to mount the partitions in fedora.

yancek · 06-28-2016, 01:01 PM

What exactly were you doing? Why were you booting a Live usb, to install Fedora? You have mixed an MBR and EFI install and this is the result. You show an EFI partition (sda1) which should contain both your windows and Fedora efi boot files. You also have a BIOS boot partition (sda6) which is used when you use GPT without EFI. Mount the EFI partition and take a look at what is there, Fedora and windows files? If not and you were just installing Fedora, it would be simpler to reinstall using EFI. There might be some other way to change this, I don't know.

schneidz · 06-28-2016, 02:23 PM

the only method i know how to install fedora (linux) is using a live-usb. everytime i tried to boot the live-usb on the pc it would go directly into windows. i had to experiment by toggling various switches in the bios for it to recognize the fedora live-usb as a bootable drive.

the only thing thats different this time i installed fedora was that it complained that it needed a 1 mb efi-boot partition because it saw something about efi so i had to create it manually.

fyi:

Code:

[schneidz@xbmc ~]$ sudo mount /dev/sda1 win

none of the screens in the install menu said anything about installing an efi (unless i missed something). do you know what command is needed to install linux using efi ?

schneidz · 06-28-2016, 03:03 PM

ok, with a little more web searching i think the correct question i would want to ask is how to boot up a linux live-usb (particularly fedora-24) in uefi mode.

yancek · 06-28-2016, 05:39 PM

From your last post, does that mean you have no directory or files referencing Fedora in the EFI directory?
What hardware as some manufacturers do not comply with EFI standard on booting? Check the link below at the Fedora Project for details on booting UEFI.

^ thanks again. i dont have any fedora stuff in /dev/sda1 (only windows stuff).

schneidz · 06-29-2016, 02:39 PM

ok, so i re-installed fedora this time making sure there was a directory named /sys/firmware/efi before running the live-usb's install process.

this is the first pc i bought in 7 years so i had no idea there was such a split between normal bios booting and efi booting. also there is no mention in the pc's manual-booklet or the on screen post messages about selecting a drive to boot. it says 'hit f2 or del to enter bios'. i read an amazon review about a similar pc and the poster said in order to install linux one must repeatedly hit f8 to get to the boot menu to select the usb (i actually tried all the function keys before but none worked -- hitting f2/del/f8 works about half the time).

the problem i am having now is that the first time i rebooted the pc, it gave me the grub menu. i selected windows-10 to verify it works and it did. but when i tried to test if fedora-24 would boot, it no longer shows grub (it boots directly into windows) ?
